A friend has a really great idea for an app that has universal appeal and a built in audience as well as buzz factor to it.
I’m looking for someone with skill sets capable of multi platform (Android, WinMo, JavaME) development (or even seperate developers for each platform) who can estimate the projects man hours and how soon they can start working.
Terms are Pay (work for hire) or Profit share (equal stake in sales).
Shoot me a PM if anyone’s interested.
Without giving too much away, apps utility is it's a kind off hot chick magnet (or identifier, depending on how you look at it). In detail it's a very useful app, can be used for both sexes.
ok minor edit to original post to see if this helps.
sounds like an app to find rape victims.
be careful.
I love it how every moron thinks their idea is some amazing multi-million dollar windfall just waiting to happen.
At first, let me thanks for your supporting to VPlayer.
I want VPlayer to be free at first, because I think the users will help me if I give out a better app. Now I wanna change my mind.
Considering the situation:
Gingerbread, Tegra 2, HTC hero, Droid X, EVO...
Hundreds of devices and feature requests are coming to me every day. And I want to accomplish these requests as soon as possible.
However, I cannot make it. 'Cause I can't afford these devices and don't have enough time to programm for a free software.
Although I've recieved many donations, but the amount can't even afford a nexus S. So many people are using VPlayer and request more features everyday. But they won't help me at all.
They didn't send me $1, They didn't send me a crash log. They just gave me 1 star, "fc on droid 2 / Nexus S", "If you support HDMI for EVO, will 5 star".
How come they want more and more but won't help any more ?
At last, I think I should make VPlayer a paid app to make it better.
Well, I don't use VPlayer but I totally agree.... If you are putting in that much effort and require funds to continue then yes a paid version would be a good step forward.
I would recommend though you try to keep some form of 'Ad-Support' version. After all, you need new numbers to test and report back.... Plus what with Google's new 15min rule a lot of users are thinking twice now before parting with their cash.
Having said that, VPlayer is easily tested within 15mins.... Providing it does not lock out/FC/Time Slip/etc at 16 mins onwards.
I'd have to agree that a lot of commenters in Market are plain brain-dead and they really discourage developers who put a lot of effort to bring quality software for free.
I will gladly pay for your app, its one of my favs!
Go ahead and make it a paid app, it deserves to be (and its your choice). Also consider an ad supported (in the settings/menu) version for us xda folks
Thanks.
I found RockPlayer to be the only player that would play an avi on my Nexus S, so I looked into buying their product. Then I realise it is done off market and tied to you IMEI number. I e-mailed asking them about this, saying I change device every 2 or 3 months and they said they would move a license twice. For this they want $10?!?!?! (On sale at $5 now I think)
I am thinking of e-mailing them back just to let them know they have put me off buying. If it was tied to the market I would probably have paid $5 already.
Anyway, to bring it back to relevance to this thread, if you charged $1 or $2 I would probably pay for it, if I knew it would play all the video types I needed.
I have to be honest though, I think your logic and reasoning is wrong though. You surely wont make enough money from this to buy every device that someone says it doesn't work on. I would prefer you were honest and just said, this app is taking a lot of time and you'd like some pay back from it. I don't think anyone would deny you that. (That sounds harsh, I don't mean to imply your not being honest now...)
Thanks.
Abitno,
Go ahead and make it a paid app. Time is money. If nobody else is providing what you have to offer I believe you should be entitled to be compensated to support development for such great work. If people don't like it, they will then have to go without an app that supports all the formats VPlayer can handle. I for sure will be willing to pay for such great work. Just make sure you strike a midpoint price. I would suggest a price range between $2.99 -$4.99.
Thanks for the great work and count on me on making a purchase although I already have the latest free version.

Be careful, I would suggest anything over $1.99 will put a lot of people off and you would end up with less...
You might find $0.99 would actually be the most profitable price point. I buy quite a few apps at that price without caring too much if they're useful or not!
Yup! I'd pay a dollar, hey if you did that you might make a killing.
I was using you app last week to watch the Cleaveland Show, really pleased so far. Personally I would prefer if it was a smaller file as have limited space on my N1.
Keep up the good work!
I've tried Vplayer on my Evo and I liked it a lot! I'd be willing to pay for it. Great software.
Agree on everything, make it a paid app!
yea, make it a paid app. But please give us a ad-version too!

best video app on the market i would go 3 on it no prob
ok, i hope you read this,
as you can see, i am living in egypt where not even Google Checkout is supported, i mean i can't even buy an app off the market even if i wanted to,
i developed a couple of apps, so i'll try to open some ideas for you,
Android Market have countries who can see paid apps, and most can't
making your application paid only leaves me no options to get it.
however making it ad-supported ( in a non spam-ing way ) makes it a good option,
you can also play with the filtering options as much as i can hear in the market to offer both versions in country specific way.
hope i made you see things more clear ...

I would suggest releasing two versions: Full/Paid, and a Free ad-supported one.
I've heard some people complaining that ads don't get you very much money, especially if no one clicks on them. I don't have firsthand experience with that, though. But even if the paid version doesn't add any extra features, label it a "donate/ad-free" version and some people would buy it just to get rid of the ads. Extra features in the full one just add more incentive, and the ad-supported one can still be used by those who can't buy it, like mezo9090.
What I suggest is that instead of making it paid, you should make it... open source. Yeah, open source. If such a great app becomes open, more developers will certainly join in (count me in once I finish that C++ course), which means more devices for testing and faster development in general. So, what do you think?
IMHO (as a non-developer) I would suggest you market it carefully. Id guess that your main competition is RockPlayer. I use both VPlayer and RockPlayer as I find some formats work better on one than the other.
I agree with a poster above that you would get a lot more response by pricing it low - I tend to be happy to throw a $ or two on a whim but anything more i tend to want to see a demo first ....
This is my favourite app - without it there would still be one area where Windows Mobile outperforms Android (well, there's RockPlayer, which was okay, but less developed, and with that annoying banner).
Add a price, and I'll pay it. My suggested price-point is £2 to £3. Congratulations on a fantastic App.
By the sounds of it, the Angry Bird developers have found it profitable to have an ad-supported version (although I know they have critical mass on their side). I's suggest a paid and an ad-free version if it's simple to put together.
All the best, very proud to have you on this board
I understand your case but if your app is to be on XDA it has to be free, or free with an optional paid version. Ads are reccomended in your case. PM me if you wish to carry on this application development, best wishes.
I'm not here to only promote my app. I'd prefer to open a much broader discourse re the freedom app development can bring, about the Android platform and development framework and other such things. I'm new to the XDA forums... you'll understand why if you keep reading.
I crafted my first Android app over the past few months. I've got a couple of old skool Symbian apps - one of which stayed in the Ovi store top 30 for well over three months (although that's not too impressive really). I really enjoyed learning Java and Android. I'm a (embedded) C++ geek and have never bothered with Java before now.
I gotta say I like it. I found both Java and Android easy and the development cycle fast. Not saying I've mastered it or anything like that it as I've only spent a couple of months working on the platform and language so far. I think the results are pretty impressive considering the effort (link below).
The story of my app creation might be interesting for a couple of reasons but it might also might bore you to tears... developing apps can bring freedom from the office cubicle. You can leave those Dilbert days behind And I don't mean swapping the office for a bedroom. I coded this app (and others) from a hammock on the beaches of Asia.
I live and work in Europe, on contract, in Spring/Summer/Autumn and beach bum in Winter. I've been doing this for years (missed 4 years in 14) and I'm always surprised how few other I meet on the road. I meet lots of fishermen, builders and tradespeople who take off annually - work in winter can be scarce. The coding profession lends itself pretty well to this lifestyle (I know this lifestyle isn't for everyone) but very few do it. I've met a handful of Israeli coders who traverse the beaches of India during the winter but that's about it.
Starting a app without internet access on remote beaches can be challenging but the samples in the Android SDK are pretty good. I used these as the base for my code. The documentation provided me with a reference for everything else I needed. I gotta hand it to Google, they've done a great job here.
I like to think the app stands out from the crowd in a couple of ways (but maybe I'm like a delusional parent ;-)). I like my UI. I paint and used to create my own comics as a kid. I've had a couple of "wow, what's that?" comments while testing it on the road. Also, there's no other app on the market that does the same thing; no competition.
I know this is kinda controversial and say the Android UI framework is just OK. When I compare it with something QT it's lacking. I guess that I believe that the test of framework is how easy it is for a coder to mould into whatever they desire. A great framework is like virtual plasticine. The Android framework is good but not great. I'd suggest the QT framework is great but I can only compare against what I've used previously. By the way the old Nokia frameworks were terrible.
So what does my app do? InterRupt measures the background noise and when a noise breaks (is louder than) the background noise it routes it through to the headphones. You can decide how much greater the noise has to be before you hear it in your headphones. It makes cycling and jogging safer when listening to music/podcasts/internet radio/etc. And it's a good solution for listening to music at work (read hammock)... which I do all the time. I can now hear my colleagues (other beach bums) speak to me ;-).
You can test my app on the market. There's a free trial - search for InterRupt.
I'm happy enough with it. But I guess like every coder, I see the faults in my own work and what I would do differently. Now, it's onto the challenge of promoting the app and this is where I don't have a clue. Any advice would be welcome. I'm now back in Europe and have internet access again.
I really like the idea of this.

Any advice on promoting an app?
Dude, it's a crowded market. So much so that it's no longer a meritocracy.
It seems dev's launch apps into oblivion and gotta find a way of bringing it to life - not an easy ask.
My app now disappears so far down the list that it takes literally five minutes to scroll to the app in the Audio category... ouch! That's after one week.
I've added a trial version and I've contacted some bloggers and Android sites that accept apps for reviews. A couple of guys have contacted me from these sites... really nice guys I gotta say.
How do most Android dev's get noticed in the crowd?
Should I choose another category? Is Audio more crowded than most?
All options and thoughts are welcome. Thanks dudes.
First of all, i have to say this is a very interesting app...i'm gonna try this as soon as i finish this reply.
i think xda is an amazing place to get started and to receive good feedbacks about how to really improve your app before advertising ....
and as for ideas.... i think a cool minimalistic website. Make sure your friends "Like" it... and that should atleast get you started ...
Thanks for the SolidKundi,
I haven't added InterRupt to my website, I had planned to do it this weekend. But it still doesn't help get word out there... people need to know the site. It's kinda the same problem.
Is it worth doing a PR launch? It seems expensive and I'm not sure if it'll get lost in the haze. I guess it might get some Google news rankings. Has anyone tried this before?
Paid apps are not allowed unfortunately.
I just need to vent. I'm a fairly active developer for the android platform. I've created a number of kernel patches and applications that I have released at no charge to the community for about 10 or so devices.
All this I do in my "spare time", which I have very little of because I am a full time professional student who takes on 32 credit hour semesters.
Recently, since my 1994 geo prizm is literally falling apart and I was hoping to scrounge together a little bit of money to get a new car so I don't end up stranded on my way to class, I decided to release a paid application. Fastcharge / Force AC toggle which allows you to toggle on and off the force AC feature. A feature which I have personally implemented and released source patches for on a number of devices.
Not only in every thread where I released the patch on a device did I write up how to toggle the feature through the command line, but I also stated that I also implemented a toggle into my completely free application that you can also download from the market, IncrediControl.
In good faith and knowing how annoying licensing is, I elected to not include licensing in my application. This is a huge regret.
Within a couple days of releasing the application to the market I googled it to see if anyone was talking about it. One of the first links was to a piracy site where a user was requesting the widget, to which another user obliged and posted the apk to a filesharing site. Doing something I never though I would have to do, I filed a DMCA takedown request, which was answered quickly and the app was taken down. Monitoring the thread, every single time a link gets taken down, another user requests the app and the original user reuploads it, most recently to 11 different sites.
So now, after filing dozens of takedown requests. This user has decided to unzip my apk, change out the artwork, and now is going around releasing it as his own work.
Really, all this to avoid paying $1.50 (only ~$1 of it actually going to me) to an individual whose yearly income is low enough that he doesn't have to file taxes?
This disgusts me.
This is even worse than the 50% "order cancellation rate" that the widget has. I'm not stupid, I know exactly what users are doing, but yet initially I was willing to ignore it. But this has gone too far.
What is even the point of pissing off a developer so much that he is considering saying screw the platform all together? It doesn't even make sense. We, the developers improve your devices, generally at little or no cost, and this is how we're repaid. With ~50% of current users of the application having pirated it. To avoid paying just over $1.
Now before someone even counters with the "my area doesn't support paid applications" argument I've actually gladly GIVEN the widget away to a number of users who casually mentioned in the release threads that they couldn't download it for this reason. Not to mention, everyone knows there are apps that unlock the market in these areas to be able to purchase apps.
How much more generous can a developer be than to provide source code patches for a feature, provide information on how to toggle the feature, provide a COMPLETELY FREE way to toggle the feature, and then charge a measly $1.50 for a secondary, slightly more convenient way to toggle.
Yet he's repaid like this .
Of course, this must suck for a developer like you. Unfortunately, it seems to happen more and more often, and all I can really say is:
I would gladly pay a few bucks for an application like IC or BootManager. That BootManager seemed really interesting, but we can't buy apps from the Play Store without CC (and as a 16-year old, I don't have one). I asked the developer if he accepted Paypal, but he didn't.
Don't get me wrong, and this is not an attack to you personally: developers, if you made something really nice, and people will like it, 70% of the people will gladly pay for it, just make sure you allow them to.

I honestly thought this was the case. It's really not. The problem is much worse than that. If 70% of users in the root community paid for apps it would be astonishing. Its made pretty clear by the number of users who download the app, back it up and then cancel the order.
If a 16 year old kid had made me that offer, the e-mail reply I sent would have the apk attached.
Well, that is a real flaw of Android: tweakability is really impressing, but these things make it really difficult to earn some money as a developer.
We have been thinking about anti-piracy measures as well, with stuff such as authentication with a server, and locking down the code and verifying integrity of APKs and stuff to make sure it's really hard to mess with the code, but it's just sad that there's a need for these measures..
The trouble is everything has piracy right from movies to game consoles through to mobiles and music.
I mean the iPhones appstore would be a hell of a lot bigger if there was no jailbreaking and installous.
Every platform has been cracked so you'll get it regardless of what you develop for.

I think you know you just needed to vent but can I change your picture.
There are some people in this world who just don't buy the idea of an idea as property. That's not compatible with this business model. That's the first problem.
The next problem is that
there's a million and one apps out there and which one are we going to choose? Where does it start, where does it end? We all have our limits. What's yours?
For me, the app has to be something very unique and possible generate me cash. For example something I use every day at work. If it's something that the phone should do anyway I tend to skip it and save the $1 for the next phone that does it out of the box. Your app is a great thing, but there's many utility apps out there. It just doesn't fall into the kind of thing I'd cave my strict budgeting for. There are people here with a 1000 apps installed and you expect them to pay $1000 in this sense.
Another way would be having utility in the cloud and then the app is free. Another one of course, advertising.
The difference with both of these is we don't need to risk a credit card with the market. That's the main reason I personally haven't bought many apps and I'd imagine it's a problem for minors too.
The very community that allowed us to create the app fails to pay for it's products is like life itself.
I'd say make something for the iphone instead because there's more profit there but that would never have been possible, see what I'm saying? That's the 3rd problem.
So you've got 3 problems there all converging into one big push towards piracy. But remember, can your app assure security that the pirated version cannot for example? This is how one has to think.
In short,
you can't do something and hope to make a bit from it on the side. You got to go out from the start and get the money aspect central from the start. I mean, that's business and of course that's exactly what the android community works hard to free us from.
Still, summarising those 3 points for suggestion:
- offer something free things can't (i.e. security, brand etc) For example, I never run pirated stuff for fear of insecurity on my data whereas I'll try out software that way on an old PC
- can always put a service in the cloud aka the javascript trap
- iphone is there if you want...
- needs to "the one app" a certain person would pay for, not something everyone likes
Also just to make that point again, if one does not believe in property then inconveniently there is no moral crime here. I suggest learn to live with this and go with the flow
I hope google sells PlayStore cards (like itunes cards) that allows user to buy apps, music, movies, books without a credit card. I really want to buy some amazing apps but i dont have a credit card so i just use free apps. I think that if u cant buy an app that cant be a reason to piracy or sidedownload that app.

The feature is 100% unique and so is the widget. Not to mention, if you didn't want to pay the $1, I provided a free way to toggle the feature in the utility app. The point is, that there is nothing forcing people to pay for the widget to use the feature. But instead of using the free option provided, they not only pirate the paid app, but edit the artwork and release it for free as their own. It defies logic.
Also, ad based apps don't work with the rooted community. I learned that early on. Myfree utility app is ad supported. With over 40,000 installs you would think it would make even a dollar a day. Nope, makes nearly nothing. That's when I realized that the same niche I was marketing to are the same people who block ads. Even if someone didn't want to block ads, they can't install a single ROM that doesn't include an ad blocking hosts file out of the box.

Be sure you're looking at all sides. Yes, you're in a losing war with guys intent on pirating your app. You can't stop them, and well, you goofed on the licensing, so someone will no doubt release the clone.
First of all, don't do the Big Media thing and assume that everybody that pirates your app would have paid for it if it hadn't been available. A lot of folks collect, or just try something once. You'll only work yourself into a funk thinking about all that money you "would" have if only they hadn't been able to pirate it. They wouldn't have. At least not all of them.
More importantly, be aware that placing something out there with value does reach folks that otherwise would have no idea of you or your plight. More than once, I've purchased an app that I don't really need, but found clever and cheap enough I can buy it without thinking about the investment. I've spent more on Android software at $1-15 over the last year than I did over the last 25+ at $30-100 a pop. I've only refunded an app once, by accident.
Finally, be up front about your situation. A guy trying to make do does influence my impulse buying. So does his reputation. If you're doing a lot, be sure that's clear on your app page, and let us know clearly you're the guy that also brought us whatever.
I am curious, though: How much did you actually bring in?
Chad- thanks for telling your story, I agree that you have every right to be disappointed. Especially the buying and refunding, that to me send almost worse because you can't stop dedicated pirating, but I would have hoped the rest would have bought the app.
It's easy to forget the human side of development, so thanks for sharing your side.
Jesus christ Chad. This is f$%&*#@ ridiculous. Probably the best and most generous kernel dev I have ever come into contact with, and people are cheating you out of 1.50. Please don't abandon Android. I need kernels when I get my rezound! but in all seriousness, warez needs to stop.

Yep. Sucks. After getting serious about android , which wasn't too far in, joining with a nexus one and seeing all the free HARD work we get, I definitely try buying stuff I use. If I can't pay sometimes I will see if dev does something else I can donate to. Its an issue I've thought about and part of it really boils down to how sorry people are in general. They want free and cheap. $1 is laughable even when it can be easily had for free. You really should market yourself a bit even though you don't want to. And people should really put a complimentary $5 or so budget a month or more and try to support devs. Maybe if you have something he gave free but has an app you won't use for a buck, buy the dollar app and uninstall after the 15 minute period. Or throw him a 5 through PayPal or something. Its simple really. If these devs don't have to resort to ramen and water they keep dev'ing especially for the community supporting him or her. And if they're eating vegetables and have plenty of red bull money it gives them wings. Otoh, the devs that make us pay to reinstall an app after we bought it on another or lost our phone suck. Balls. Won't buys theirs anymore.
teach a man to fish, you feed him for life. teach a man to fastboot, and you create competency. and less threads on xda.
Maybe you should implement a system like some developers do where you download the app for free with a time limited trail, then they would go to another website to pay for the app to unlock it, and the unlock codes would be unique for every user which would minimize piracy.

In the Netherlands we have prepaid Visa card.
Works well.
Maybe you google something similar in your own country.
(3V prepaid Visa cards)
That does suck but if someone wants to pirate an app even licencing doesn't stop them as there is an app that apparently patches licence checks.
It is so easy for even a non root and new user to find cracked apps, I have seen links on here and even on peoples facebook sites, it's got to the point where people can just browse a webpage and click a link to get the cracked version of an app.
Unfortunately if someone wants to crack it they can. Unless you could implement your own security check somehow, something obfuscated in the code, licencing is the only alternative as it would stop people using backed up cancelled versions at least.
Unfortunately it seems a lot of people just don't want to pay for apps.

also have to look at both sides. some people just refuse to pay for **** whatever it is, or get it as cheaply as they can. being android apps, the free route is how they're going to go. but the other side, you hsould be grateful for all the people that do pay. they're the ones helping keeping google, open source, android and everything in between chugging along. open source is the future and you can tell every corporation i said that. and thanks for you your work even though i've never used it.

There is plenty to disagree with in your post as it all seems like an attempt at rationalizing ways to get around the system. This last statement is a ridiculous attempt at summarizing why stealing is OK. Your morals don't define the crime, the law does. Stealing property, physical or intellectual, is not legal and not right regardless of your morals or lack of.
Chad,
I am sorry to hear of your products' abuse. I used your kernels all the time on my Incredible devices and bought IncrediControl to support development. I have purchased many applications just to support development and believe that is the way to get high quality applications.
Piracy is just so damn easy on Android. I know ppl that are doing it who I wouldn't even expect to be doing such a thing. This guy I know love android only because he can get everything free by just googling the apk.
awww thats sad i feel really bad for you!
I've used pre paid visa debit cards to buy apps. You can find them in Any money shop like Cheque cashing places for example. You can even just stick a dicky diver (£5) on them. Perfect for situations like this

A friend of mine is a car salesman and is looking for an app that he can use to quickly access information about cars on his lot while talking to customers. He asked me if I could "throw something together".
I recently started doing android development, and I've gotten about as far as doing the Hello World and a couple of other tutorials, and this sounds a little beyond me. But it seems to me that there must be something like that already - only when I google terms like "cars sales app" and so forth, I get a lot of free apps that were built for specific dealerships, for selling to their customers. Not so helpful.
What I have in mind is just a simple catalog of the current inventory - a big picture of the car, a screen full of details the customer would be interested in, a screen full of technical information for mechanics and salesmen.
If something open source exists, that's similar to this, which I could modify as needed, that would be ideal. If the exact thing I'm describing exists, that would also be awesome. If nothing remotely similar exists, then I hope one of you can make a million dollars building it, because it'll probably be a few months before I'm at that level myself.
Any ideas?
Why not just create a spreadsheet with all the details in and use one of the many document viewers to access it?
Or build a very basic internal website he can browse from his phone?
Anything else seems to be overkill to me.
Maybe he could just use an already-existing database app ? Sounds close to what he wants and they already exist. You know, if he wants to spend as little money as possible.
A web-site could also do the trick, do they not already have one ? Do they already have inventory on-line or not ? Where is the database for their inventory even housed and how is it updated ?
It seems like overkill to me to have and have to maintain two databases. Is that what they actually want to do ? Are they okay with that extra work ? Who is going to be updating it ?
Do they really want an app that can use data from an existing website or database et cetera ?
Honestly, it sounds like he's asking you to "throw together" something that would cost him (possibly tens of) thousands of dollars to have personally developed otherwise. Why doesn't he just go for a service that already exists ? Like this (no idea if it's any good, just Googled). In that situation they've already developed the app and interface and just need to plug you in - so most likely less expensive than developing something totally custom.
I think this is probably out of your reach unless this guy really wants to maintain two databases just so he can have one on his phone - that's him or another employee constantly updating this thing with all that information you're thinking of putting in for each car. Do they have the time, desire, or manpower to do that ? How did you, when you wrote the OP, envision this "app" being updated to keep inventory current ? Would YOU be the one doing that ?
I know you're new and don't value your skills highly (and at this point for legitimate reasons - you don't have the skill to do anything you want right now and that's okay) - but I'm just going to put in my two cents and say that I think you're getting used. Cool if he just wants you to set up a frame work and is cool with maintaining it himself - that's awesome - but I'd think an existent database app would work just fine if that's the case.
