Application Security/Java questions - Android Q&A, Help & Troubleshooting

While I'm not new to the Android scene, I've just recently begun learning coding and development. I have a small background in Java development but obviously never Android. In any case, my first project was developing some code for a friend that would prevent the .apk from being pulled through ADB and then decompiled and uploaded to warez file hosting sites. I believe I have most of my code correct as the compiled .apk will check against the market, but won't notify the user if it's an illegal install. Any help on this matter would be greatly appreciated. Please reply to this thread, or contact me via GTalk at [email protected]. Thanks!

Q... How to set up Linux dev environment

Ok I installed the jdk on 11.10 ubuntu. The installed eclipse from the software center. I'm currently installing the android sdk. All of the sdk. I'm assuming using eclipse I should install the adt plugin. I'm interested in developing an app. Any pointers would be awesome. If anyone has any links to read up on app development for newbs I would be grateful. I would like to build a ROM to, something for personal use. I would post it if I ever feel its worth it. I'm interested in learning development and i have some great ideas for apps that do not exist that could be decent money makers. Just gotta make the thing. As I already said any help or advice would be awesome. Links would be cool to read up on. And thanks in advance for anyone who helps.

Adding htt p: / SOMETHING /download.eclipse.o SOMETHING rg/releases/indigo (Indigo Repos) to your "Install Software"-List solves it.

[Q] Is dex2apk possible on ANDROID PLATFORM?

We have apkbuilder tool in Android SDK for Windows, Linux and Mac OS. Is it possible to develop a similar tool that runs on Android platform?
My friends and I are working on a MiniJava compiler on Android platform, and we hope that the whole process - getting the MiniJava source code, compiling the code into dex file, packaging dex into apk - can run consecutively on Android. Now we're having trouble packaging dex into apk, since the "apkbuilder" file runs some Java commands. Please help me if you have any idea.
p.s. This is my first post, so please tell me if there's something improper.
Please use the Q&A Forum for questions Thanks

[Q] What is an Easy way To Develop Android Games/Apps

EDIT: How Can I Easily Make a Sidescrolling Platformer Using An Easy Scripting Language For Android
Bump
Nobody Answered Yet I Modified My Post
Im Really Eager to start Making Simple Platforming Games For Android
bump Someone please post
There is no easy way. Anything that is worth doing is always worth the work you need to do.
Here is a Java-Script Builder
Don't know if you know anything about writing script or anything but you can PM(private message) me with an email address and I'll send you a zipped attatchment with a program for windows pc. It's called Sencha-Touch 1.1.1 App Maker.
I'm sure if your running windows on your PC and your here then you already have java runtime. Just update it if necessary at Java.com. Just click where it says "Do I Have Java" to check and update your version.
You will probably also have to go to Oracle(the java website) and download and install the "Java SE 7u2" for developers from the download section.
If you Need direct links to the Java's, I will include them in email to you.
Hope this gives ya some insight.
Can't get the zip to upload to an email but can give ya the website link in one. Don't think I'm allowed to post outside links.

You can get it for free at their website and ask questions on their forum if you need help with it.
Eclipse + Android SDK
I highly recommend using the standard Eclipse setup with the Android SDK. Java is pretty easy to learn, and can create games that are very simple to complex. I was confused where to start off as well, and tried out AndEngine. There isn't much documantation for AndEngine, so I followed Kilobolt's tutorial on game development. One of the best tutorials of programming that I have ever seen. I am working on a platformer at the moment, and everything is going pretty well. In simple, google "Kilobolt". He has tutorials for setting everything up. However, the tutorial begins with standard Java development, and Android comes into play when you are ready to port the game. Good Luck. :good:
Thanks for the info, I'll check it out.

[Q] I want to know how to change the system camera apk of the GS3.

Greetings!
Well, is how the title says. I want to start making my own systems apps. For instance, I want to start developing a camera apk for my GS3 but the problem is that I don't know how to do it. I don't know how to open those internals files like xml files(they do not open correctly with a note app), .rsa files, .mf files, .sf files, .dex files, .arsc files and the list continues. How to compile and discompile apks or flashable files...
All of this is because I want to star my own proyect, and through this way, to enter the android developing community of the GS3!
If anyone could help me to accomplish this I would be VERY grateful! If theres a guide (I tried to look for one but my research did not throw any result) that would be better!
Hope you could understand me because English is not my main language, but hey, I'm learning
Thank You SO MUCH for YOUR TIME!
Personally I think you should start to learn the programming and code from your toaster, but hey - if you want to damage your S3 - it is your free will (I hope)
OK, let's go to the matter, first. Assessing your coding skills based on your questions, I decided that you should start your learning from this.
Furthermore, to be more presice against your questions, if you would become literate expert in above linked knowledge, feel free to use
this as a small sample.
If it made you curious, why not try for even more interesting news?

Hello Beautiful community of xdavelopers!
I am just getting started with cordova/phonegap
I was so curious how can I connect to mysql in cordova and display its contents in app. So I came across this website that shows how to achieve the same "https://codesundar.com/phonegap-php-mysql-example/ ". I am basically trying to make android app using my web skills so I came across this ADF 'Cordova'.
I am just in alot of doubts but first one is security. When I write a code in php to connect and fetch data from mysql to display database or use mysql for user login credentials verification and build it into .apk anyone can reverse that and decompile the .apk to fetch the php code and the credentials used to access the database right?
What is the secure way around this?
As I know php is a server side scripting language so .php files are not accessible from browser so that makes it a bit secure but in case of cordova the php files will be compiled in the .apk with cordova build command
Please clear my doubt
