[Q] Help Needed developing newest battery tweak

Collin_ph here. I've been working for literally months trying to get my battery tweak on the android market. The problem is that I don't do front end java development.. or should I say, I never have done it before. I have 2 full time jobs as a developer and a business owner and really don't have time to learn another language and framework. I'd LOVE to work with someone who A. is Experienced, and B. Has the time to work on something like this.
The next version really is going to be great, I just think it's time to get it on the marketplace so it's compatible with more than just certain ROMS on the Hero. I know it's technically possible.. I know the ins and outs of making it work, I'm just way behind on making a pure android app. If anyone really really wants to help, let me know. I'm wanting to make a profitable app on the market, and I want someone who'll share in the vision and the profits. There'll always be a free version, especially for XDA users. If you're interested, please PM me. This will make 3 times I'll be starting over because developers don't really have time to work on the project. If you're like me, you know this has potential.

Let's do it

collin_ph, will there be a shell script version of new battery tweak too, yes?
i think shell script is efficient and stable enough for me and i don't want to install an android java app.
love your tweak!!

LOL, with JM throwing his hat in the ring, you KNOW you're gonna have a winner!
A huge thanks to both of you guys!

In the long run, I really don't have any plans to continue the shell version. There are a lot of misconceptions about the shell version-- a lot of people think that there is no process that continues running, however, there is. I have a plan to have a very similar setup with the java version that should still have a small cpu and memory footprint.. possibly even smaller CPU usage as the Java version can be event based rather than timer based. Anyway, just know that I will do whatever possible to make the program fulfill its need the best and most efficient way possible. With Java, we can be usable on more than just a hero without having to port it every time, we can run on different roms without porting, we'll be able to run more things event based and remove most of the timer based things (if not all), and lastly, we'll be able to do things that we weren't able to do in shell. I'm excited for the new version, but as always, it's job is to make the phone faster and give it better battery performance. The new version will most likely be called "tweak tool", as Battery optimization will be only one of its functions, but the most important.
Anyway, after Easter, I'll be sitting down and going over a plan for the new version (once more). Hopefully we'll get a full blown launch out of this attempt.

Haha. I'm excitied. Hopefully you two will join together. This is gonna be outstanding! Ha. Yea I know I'll shut up.

I'll have to learn how to write Android apps. Already know Java.
Can't be that hard after modifying Android source, right?

If you set up Eclipse, there is a lot of help/examples available. App Inventor is another tool that might be an option, perhaps less flexibility, but a "block" oriented approach that does a lot of the work for you.

I've tried appinventor and as a developer, it feels totally bass ackwards. I'm no java developer, but I've already put together a couple of tests in eclipse, which is the direction I want to go-- especially since I'll be doing everything in my power to make sure it's optimized.

Holy crap, if you AND jaybob are going to help collin_ph, this app is as good as gold. You two are by far two of the most dedicated and steadfast devs I've ever known on XDA.
Excited to see what comes out of this, happily willing to buy any app that comes out of it as support

Ok, I lied :-)

Ok guys, it's been brought to my attention that my post was
1. Cantankerous.
2. Seemingly disrespectful of devs great work on here.
3. Taken too seriously for being an internet forum.
I would like to say sorry, and explain what I mean I tihnk it would be awesome to pull together the necessary funding for our very talented developers to create an XDA exclusive, completely original ROM. I'm not sure if it is possible, but something that is just for the Thunderbolt alone and isn't sense, isn't AOSP, isn't MIUI, and DEFINITELY not like Motorboat... I mean Motorblur. I think we really are on to something with the work that the Dev's are doing with taking different roms and porting them/using other roms as bases and then building from them; lets see what we can do to completely change the way that this stuff is done(if possible) by polling ideas(not unreasonable wishlists) and putting it all together. Possibly coordinating between Team BAMF, Chingy, and some other the other recognized DEV's.
What does everyone else think?

If it isn't sense/blur/touchwiz, it is AOSP. Miui is just modified AOSP (with no sources given back), just like all the other roms not sense/blur/touchwiz are also based on AOSP. You do know what AOSP means right? Android Open Source Project as in the android operation system that is the basis to all android phones just modded by the OEMs. What you're asking is similar to saying:
"Hey, I'm bored with linux, unix, osx and windows, can we make a new operating system totally not based on any of those for our computers?"
Perhaps rephrase your question one more time in a way that makes more sense? Third time is a winner

Ya got a point, I actually didn't know that! BUT, regardless of how its phrased, what do ya think it would require to do somethig like I mentioned? I, personally would love to see something excitingly new put out here. Like with the miui project, any chance of people putting their heads together to figure it out?

You've got OS's and you have UI's. Obviously it is entirely possible to custom build a UI, but its FAR more difficult than porting one over or mixing and mashing parts of Sense together. UberBAMF is definitely something new and out of the box. That's more radical than anything I ever expected... Or have ever seen elsewhere. UIs do a lot to sell a device, so its worth it for HTC or Samsung to invest in building one. Not so much for a team of volunteer devs.

Chances are unlikely to get a new user interface geared to only one phone built from the ground up from the android source by a team for a few reasons:
1) Lack of like-minded (knowledgeable) developers for one device that are currently free. Developers are very opinionated (just from my own experience even if they don't want to admit it). What should/shouldn't go into it would be a mess to deal with and debate alone, especially since the opinions of developers are generally not the same as those that don't develop. The ones already developing most likely don't want to give up their current projects as well. Basically, the developers that want to develop already have their projects and most treat them like it's their "baby" and most likely not willing to give them up or put them on hold. That moves into issue #2
2) Time. It would take considerable amount of time and organization to do that. Probably to get something stable that's original would take longer than most people would keep their Thunderbolt. Guys that work on their phones do this part time for fun as well and that combined with other side projects would press for time.
3) True developers & designers. There's a big difference between hacking some already made stuff to work with things and actually writing object oriented software from scratch. Obviously some guys putting stuff out for the thunderbolt are true developers that code professionally and others are just hacking around making things work done by others. Both have their uses, but you need real development for something like this and I don't think there's enough of those willing.

Forgot to add that the only way change happens is to build interest, so don't let my pessimistic observations detour anyone from posting their thoughts and ideas in this thread

Official: Palmdroid Development Thread (android app emulator for WebOS)

After speaking with some of you it has become readily apparent that while many people are comfortable waiting for a full android release for the HP Touchpad, there are also quite a few people out there that do not want to switch to a full android OS but simply wish they could have access to the vast app collection that android has to offer.
For these people I offer a solution.
Palmdroid​
The Palmdroid project is going to be an ongoing development project to bring a Dalvik like port to the Palm/HP WebOS operating system.
The goals of this project are as follows:
1) to offer a Dalvik port to WebOS that allows for android app emulation as if they were native WebOS apps much like Alien Dalvik on the nokia n900 or the app emulator of the blackberry playbook
2) Share useful information throughout development with the Touchdroid team as to help them reach their end goals and avoid conflicting and overlapping work as well as to foster collaboration and new ideas to speed the project along.
3)If possible (either worked into the project from the start or through later additions) provide the emulator as a download through the WebOS homebrew App catalog.
Now with the goals outlined I'll move on to how this is going to get going and what needs to happen next.
1) First and foremost... I need volunteer developers. If you have experience with Dalvik, WebOS development, Android development, UI development, C++, Java, Etc. I would like you to PM me with details regarding what you can help with. I have some java and C++ experience as well as a ton of web dev and project management experience but with alot of this I am learning as I go and if this is going to get done with any sort of speed I NEED your help.
2) I will be setting up communication channels for the dev team to discuss what needs to be done, share work, etc.
3) I will be setting up a web page (an extension off of my own since I can't finance purchasing another hosting account or domain name right now) where there will be regular updates on the status of the project as well as a section for the dev team as a repository for project related research, source code bits, group status reports etc.
Until the aforementioned steps are met this thread will be used to offer info, updates, and discussion related to development of Palmdroid.
I hope to have the support of the community here as we move ahead... i know I am new around here but I am very passionate about making this happen.
WebOS is a great operating system... and Android has some amazing apps... won't it be an amazing world when you can have both!
Palmdroid Coming Soon​

PS. this should probably have been in the development section but apparently I can't post there because I am to new here so forgive me. If a Mod would like to move it and give me posting abilities that would be fine.

I subscribed to this thread even tho I have no WebOS devices at all. But I'm intersted in this project's work (I'm not a developer just a "hacker") as the same idea was proposed in the Bada section, too. It seems quite a lot of work to do this, as it's not enough to port dalvik itself, a big chunk of android has to be ported also to make it work. But it's an interesting project!

Agree! I don't want the entire Android OS ... All I want is the apps running on a webos emulator.

Great! Thanks! I'll be watching closely!

while I probably cannot be of use for the development, I can be helpful for some other things. For instance, I am in the process of creating a logo for the project and also searching for possible devs. I will contact the touchdroid team and see what they think.

Brilliant Idea about starting the dev work
I would support this development and I am sure countless others who have just purchased $99/£89 HP Touchpads would do so. Once again thank you Robo-Rooter & Failhard to start this work.

Just got my 32gb Touchpad in the firesale. Really loving it so far. Having android apps on it would really top this device off. Good luck.

Have been using the touchpad for a couple of days and am amazed at the elegance and sophistication of the webos. Though an old android user ... I absolutely love the webOs interface.
Would love to see the palmdroid happen ... ALL THE VERY BEST GUYS ...
Thanks Robo-Rooter & Failhard for initiating this.

This would be absolutely perfect. I wouldn't want to ditch the WebOS but still be able to run Android apps.
You have my full support.

Great idea!
Great idea!

I have a droid (DesireHD) myself and comparing the droid's interface and webOS, I really like webOS. And looking at how the patches and O/C makes the whole tablet runs silky smooth, I really want an android app emulator. Current apps in webOS's catalogue is pathetic, but combining android's apps and webOS interface is the best one can get.

Subscribed. If I can't get the Android OS, an emulator would do nicely.

Yeah it will be great to those who want to keep WebOS

I am a long time webOS enthusiast, and I am hoping that I actually get one of the 6 TouchPads that I ordered over the last few days. I think your proposal is the best way to go, and would be way more useful, and probably easier, than a full dual boot android port. I just wanted to list some resources here to bring to everyone's attention. While XDA is the most amazing collection of talented Android and WinMo hackers, you probably want to enlist the help of the aces that live and breathe webOS. Here is where to find them:
http://forums.precentral.net/ Definitely the most popular webOS forum. All the homebrew devs and hackers hang out here.
http://www.webos-internals.org/wiki/Main_Page This is where all the nitty gritty is documented in a Wiki. I have known some of the webOS internals guys since the day the Pre launched, and they are very talented.
http://webchat.freenode.net/?channels=webos-internals This is their IRC channel.
Also, if anyone has not seen it, they have already got Ubuntu, including window managers, and apps like GIMP and LibreOffice, running inside cards in webOS. This leads me to believe that the Palmdroid concept is VERY possible.
http://forums.precentral.net/webos-development/292457-tutorial-how-get-ubuntu-touchpad.html
The nice thing is that lots of great auxiliary tools already exist to speed up the process, such as MetaDoctor for creating custom ROMs and Preware for downloading and compiling virtually any linux arm package.
Best of luck with everything. I am subscribing and will help where I can.

This is what I was waiting to hear!!! Let us know where to donate!

Q Best Linux desktop os for Android development

I was wondering if someone can recommend what they think that the best Linux desktop os would be for Android development. I was using Linux Mint but recently I switched to ubuntu. I have been recommended to use fedora or debian. I was just hoping to get opinions on which would be the better for a new dev to start using. Thanks in advance.
Sent from my SPH-D600 using xda app-developers app

What did you settle on and why? Cause I'm trying to decide atm too...
I know I'd be more likely to stick with debian/ubuntu based because it's just the type of package management I'm used to... Ubuntu has become my goto... or lubuntu/xubuntu if I need a lighter footprint, kubuntu if I'm looking for a more refined desktop that guests might be more comfortable with... You just can't beat the amount of packages that are "already ready already" in the ubuntu repos and the online community/following ubuntu has for quick help.
I am, however, a little more likely to try something different for the particular purpose of android development if recommended by a lot of experienced people.
I see more responses in older threads... but things change quickly in the OS world... especially with fast pased release cycles of some distributions. I hope some actual xda recognized developers give some feedback here.
I know a lot of people will say it depends on your needs and what you work best with and what works best for you and how you work and how I drink my sweet tea and blah blah blah... I want to know what you guys that are actually doing it are using and why so I can make an informed decision.. or else I'll just go with my goto (ubuntu)... but just in case I'll be clear about what would help too... That doesn't meant I don't care to hear opinions outside of the scope of my desire if you have good reasoning.
1. Package management. Easiest install/configuration of the specific tools needed to develop for android apps and package apk's, and android itself... kernels, build roms and similar non-app system component development or repackaging.
2. Of course an environment that feels intuitive and is conducive to the creative process involved is equally important.
3. This probably going to be a given in any distribution (I'll mention anyway...), but communication and resource access is important too.. so irc, web (xda-developers forum!), email...
I value the thoughts and opinions of this community. I've been getting great info off here for years. I'm just now starting to participate in the forum, but that's just because I've never been a forum person... I was just an irc and google geek... but when google takes you to great forums like this time and time again... I guess its time to grow and change. I'd like to be a future contributor too, it feels nice to give back...

I guess I'll stick with my combo of Windows 7 and Ubuntu. I will be changing desktop to classic gnome though. I'm not prepared for a radical change like unity... still just looks like a netbook launcher to me.. sadly the newer gnome releases seen to be heading in a radical direction as well.

[Q] Any good books on Android OS development?

I was just wondering if there were any good books about developing the Android OS. I am talking about taking source Android and developing it into something phone specific. Like HTC sense or Samsung TouchWiz. (I know they are both completely different processes). So if anyone could point me in the direction of a book specifically about developing android from the ground up, that would be great. Thanks

Developing Android or developing apps for Android? Can't do the first as it's done by Google..
For apps, read some reviews on Deitel's Android for programmers or Busycoder's guide to Android development... The latter will teach you via examples.

I am talking about developing android ROMs and possibly something like Sense or TouchWiz from scratch. Not a port of either, but something like that. I have just realized that all either of them do is more or less a system of APKs strung together to form a sort of OS within an OS. So I guess I will take a look at app development. Anything along the lines of launcher development and replacement system apps would be great.

I know right? Some people like reading physical books, rather than a tutorial thread, to learn development. I still have no hits for a book on developing (or cooking) ROMs. I will keep a look out. Rather than wait, I have simply purchased a book on app development and am working on a launcher app. We will see how it goes.
