Database Info

[Q] Hello World!

Thats where I'm at...
I'm going to learn java then transition to android with the end-result being an app developed for android. I don't think it will be a difficult app to develop. A database with a front end GUI for data entry and retrieval with export and backup options. Nothing flashy or fancy, but nothing that currently exists fits what I want it for the way I want it. I would like to have it done by the end of the year working around real life.
I am completely new to Programming. More of a power user, but that is where it ends... I am a complete user.
I bought a book called Java 7 for absolute beginners by Jay Bryant (ISBN 1430236868)... Can't link to it because of anti-spam rules. Don't know if it will help.
What are some other books (I can't learn with e-books... I do better with a textbook) that the experts here would recommend?

Java is good, but you also have to learn all about the Android system.
This includes activities, providers, cursors, listviews and any number of things that are not in your Java book.
The usual mother lode for Android documentation is the, um, Android documentation!
http://developer.android.com/reference/packages.html
Short advice on how to write your app (pretty much standard advice for anything at all DB related).
Write a provider for your information that is backed by an SQLite database.
Write an activity that queries this and uses Cursor and CursorAdapter to fill a ListView.

I wanted to learn the programming language basics before throwing android into it.

A new App for web-tinkerers (Open Source)

I don't participate much, but I've learned a great deal from this site. So I'm posting this here as GPL2 software as a way of thanking everyone. All I really ask is that it not be used in a closed-source app without talking to me first.
Can't poast URLs, because I have fewer than 10 poasts (I lurk hard). Mod, if you don't deem this to be spam, would you kindly provide the link (or allow me to do so)?
[sourceForge.net]/projects/webremote/
Basically, this was meant to be a generalized HTTP(S) client, with the URLs being assembled dynamically and under a variety of different circumstances. The server-end of the transaction is a creation of the user.
I wrote this tool to assist me with repititive tasks at work (specifically, asterisk/linux administration). I wrote a PHP page to do things like add users, check server load, trigger recordings and dialplan modes, and so forth.
I have also used it in conjuction with a Raspberry Pi to trigger relays and read sensors in my home from wherever I happen to be at that moment.
There are lots of things I want to do with this app...
Implement GPS, so I can trigger URLs at waypoints.
Tie into NFC and make a bitcoin wallet that you can "bump" or scan a QR code to pay someone.
Implement Trigger packages to support one-click importing of Triggers for a specific task (IE, minecraft server administration)
Use BouncyCastle to encrypt the DB.
Hook into the camera and fire triggers using snapshots (or image files) as arguments.
Actually cause the HTTPS Receivers to validate certificates. Presently it does not (although the traffic is still encrypted).
I will take requests, questions, and bug reports at the sourceforge page, but how fast things get done will directly correlate to how much interest the project attrracts (which may very well be none).
For those learning how to program and trying to learn something by reading the source, I'm sorry.
I've tried to keep things hygenic. I come from a C/Java background, so Android was a bit of a leap, with respect to its organization. This program is a work of evolution.
To check out the source, use subversion:
svn checkout svn://svn.code.sf.net/p/webremote/code/trunk webremote
My working copy is also my Eclipse directory, so importing it with Eclipse should be minimal trouble.
If anyone *really* wants to thank me, I am a bitcoin user:
12rA36FH4NUFZojxyxQgWmQm6WUnzfQ1yR
Or you could buy the version I have up at google play (but I consider this a donation):
Can't poast URLs.... Search the Play store for WebRemote.
Thank you all again for sharing your knowledge.

Best back end for Android app?

I appologize if this is a dumb question, but I am new to app development, altough some experienced in php/html.
I want to create an app where user fills in forms. The app development is easy to find info about, but i also want a back end plattform where I read the submitted forms and organize users.
So, my question. Is there a sort of ready wordpress like plattform to customize, or should this be built from scratch? If so, which platform is the best?

One note I should add about Buddy (full disclosure: I work there) is that we maintain independent instances of the platform in different locations around the world. If you need to host your backend in Europe (for response time or data sovereignty reasons, for example), you can choose your app backend to be sandboxed in the EU. Likewise the US and likewise China (with Brazil, Singapore and Australia coming soon).

he best way to develop mobile apps is to use REST services. So now you can choose any thing.
Any language that can used for server side programming can be used.
Now it is up to you choose the language.
If you familiar with JavaScript then you can try nodejs. You can make small app server in it.
But if your server software design is very complex (containing threads and synchronisation) then java can be handy.
But there is no restriction of language.

Firebase should be also a way to go for this.

The best android back end services include, Parse, Kumulos, Kinvey, backendless, QuickBlox.
Concerning the forms where users can fill up information, would something like help out?
https://play.google.com/store/apps/d...solutions.fasp
On Apple's platform you might need an iPhone developer - it is quite possible to create and publish an iPhone app using your form.
I did take the help of mobile apps development service in toronto to know the process which is described here: http://support.brightcove.com/en/app-cloud/docs/step-step-guide-publishing-apple-app-store-using-mac

Thanks Carol for sharing such a wonderful article.

I have heard good things about Hasura (Not affiliated in anyway). And I think parse - mentioned above - is no longer available.

I'm wondering why nobody mentioned Google CLoud or AWS. They are most mobile friendly for a good price

Hi, if you will decide to build from scratch, there are different options/frameworks. But If you use kotlin you should look to Ktor.

PHP is it possible?

Hi experts,
I am an reasonably good php scripter, but know just the very very basics of mobile app development (Java/Smali/Android Studio).
I really have no interest in trying to learn enough to build a decent app as time is a big limiting factor for me.
I have an idea for an app, and I know I could do the whole thing in php quite easily, but I would like it to be a downloadable app, is it possible to write my software in php, and then have a very basic android/IOS app that basically just loads the website, the only thing the app needs to do, is run the webpages in fullscreen and hide any browser elements (url bar, scroll bar etc). The only thing that may be challenging is enabling "swipe" abilities, but I can live without that and just use hyperlinks for moving around, I would also look at preloading content so the app runs smooth. At some point if the app gets any interest I would pay to get ti developed properly.
Keen to hear your thoughts - maybe there are other apps already doing this I can copy, and I know some may say why not just make it browser based, but I believe the app store itself its the critical part of advertising and exposure of this service, also means I can release a real app version in the future and have it pushed to all devices.

Conceivable assaults ¶
Utilizing PHP as a CGI paired is a possibility for setups that for reasons unknown don't wish to incorporate PHP as a module into server programming (like Apache), or will utilize PHP with various types of CGI wrappers to make safe chroot and setuid situations for scripts. This setup typically includes introducing executable PHP paired to the web server cgi-receptacle catalog. CERT consultative » CA-96.11 prescribes against setting any mediators into cgi-canister. Regardless of the possibility that the PHP double can be utilized as a standalone mediator, PHP is intended to keep the assaults this setup makes conceivable:
Getting to framework documents: http://my.host/cgi-container/php?/and so forth/passwd The inquiry data in a URL after the question mark (?) is passed as summon line contentions to the mediator by the CGI interface. Generally translators open and execute the document indicated as the primary contention on the order line. At the point when summoned as a CGI paired, PHP declines to decipher the charge line contentions.
Getting to any web record on server: http://my.host/cgi-receptacle/php/mystery/doc.html The way data part of the URL after the PHP twofold name,/mystery/doc.html is traditionally used to indicate the name of the document to be opened and deciphered by the CGI program. Typically some web server setup orders (Apache: Action) are utilized to divert solicitations to archives like http://my.host/mystery/script.php to the PHP translator. With this setup, the web server first checks the get to authorizations to the registry/mystery, and after that makes the diverted demand http://my.host/cgi-canister/php/mystery/script.php. Sadly, if the demand is initially given in this shape, no get to checks are made by web server for record/mystery/script.php, yet just for the/cgi-container/php document. Thusly any client ready to get to/cgi-canister/php can get to any secured archive on the web server. In PHP, runtime design orders cgi.force_redirect, doc_root and user_dir can be utilized to keep this assault, if the server record tree has any indexes with get to confinements.

[APP] Seeking Help To Rev Engineer My Own App

First I want to make this clear right from the start that I am the developer/author of the app I am wanting to reverse engineer. There is nothing illegal or questionable about my intentions.
If I have posted this in the wrong section I do apologize and would ask that it be moved to the appropriate section.
Before I go into any specifics of what the app does or what it is used for; the reason why I am wanting to reverse engineer the apk back into source code has a somewhat unique origin that very few people will ever encounter. About 4 years ago I began development on my app that is now known as Ls Droid. I did not know any Java code and I had an idea at the time that lead me to find a development tool created by MIT that was known as App Inventor 2. If you've never heard of this before, App Inventor is a GUI based programming language based on Googles Blocky that allows the user to combine various types of blocks that each represent different code functions and create working Android apps. I'm not going to discuss how App Inventor works but you can read the overview of it at appinventor.mit.edu/ . Over time my app outgrew what MIT's version of App Inventor was capable of and I moved my app to another platform(Thunkable) that was still based on App Inventor but greatly expanded on it's functionality and was capable of dealing with larger projects than what the MIT servers would allow. I used Thunkable for several years and ran my app though it's entire Alpha development life cycle and into an open Beta. Unfortunately Thunkable had been creating their own(improved) version of App Inventor from the ground up and not only was it incompatible with app's created on the App Inventor platform but they did not include many of the things my app required to work and I was forced to look for another platform to move my app to in order to continue development. Unfortunately by this point all of the spin off versions of the original MIT App Inventor had created advertising components and the majority of people using these GUI based programming platforms were now focused on creating earning apps. As a result the people running spin off versions of App inventor are now focused on providing tools based around add based apps and less interested in fixing basic functionality for core components as they are rarely used in earning app.
So this brings me to my current situation. The compiler used by the current GUI programming platform I have been using for the last 8 months or so has become unreliable and buggy. Core functionality of how specific blocks function has also been altered several times in the last 6 months and each time a change like this is made requires dozens of hours to restructure my apps logic to work with the new changes. I have tried to leave these GUI based programming platforms several times and move my app into Android Studio but have never been successful. Attempting to recreate my app from scratch in Android Studio would be a massive undertaking even for someone fluent in Java and I only have a basic understanding of Java at best. I can however work from existing code and alter or restructure it with out a lot of trouble and that's basically all I need to do in my app at this point.
I have worked with a number of people in the past who have tried to help me turn an APK back into source code that worked in Android Studio and about a year and a half ago I was working with someone who was able to decompile the app and successfully import it into Android Studio where it did mostly work with the emulator. Unfortunately this person was killed in a car accident, I do have a copy of what they had done that was close to a working version but I was never able to get a copy of the source they had working in Android Studio. I have had a couple of other people look at this code since then but no one else was able to do anything with it. At this point the version that was being worked on that did open in Android Studio is old enough that it bears very little resemblance to the current version of the app and attempting to even work from this code now would be a massive step backwards.
In the past I have always looked for help from automotive reverse engineering forums since my app has a very unique purpose, it is used to read and write the binary code from an engine's computer on a number of General Motors vehicles that are popular/common in the hot rod community using a Bluetooth tool connected to the vehicles OBD II data port. I created this app to remove the cost barrier that had previously been required when you wanted to make changes to an engines program on fuel injected vehicles....my app is free and uses a relatively cheap OBD II tool. There are thousands of people that have used my app over the last couple of years and successfully re-tuned their vehicle with many of these people being able to do this with no cost out of pocket as they already had the tool my app was designed to work with.
My app is now at the point where even making basic changes or bug fixes is becoming an issue due to constant changes in the GUI based programming language. I have exhausted the help of various automotive community's, mixing smart phones and cars was a long shot in the first place and here I am 4 years later with a very successful app but it's well beyond what my network of car hacking colleges are able help me with. It's no secret that XDA has some of the best Android developers(and hackers) anywhere on the web so I figured this would be the best place to turn to for help.
Maybe this would be fun for someone here? I doubt people get a chance to decompile and reconstruct an app legally....and if they do it's extremely unlikely it was done on an app built with a program like App Inventor. I have no issues making my apps source code public so I have no issues discussing anything to do with this publicly, but if someone would prefer to discuss this by PM or Email I'm fine with that as well.
My app can be found at ls-droid . com near the top of the page, there are a couple of versions posted currently with 2.2B being the last public release but it's not exactly current. I do not want to post the APK for the most recent version of the app I have been working on at the moment on the off chance someone wanting to use the app were to find it since it has some pretty nasty bugs right now due to compiler changes. You can search Youtube or Facebook and should have no trouble finding information on my app if your wondering how it works.
