Hi,
I'm trying to learn Android programming.
In order to do so, I have extracted an apk in order to understand how it works.
My goal is to enhance an existing apk, for personal purpose, and I taught that it is the best way to start.
So now I have my source extracted from an apk.
How can I add it to Android Studio so I can start to debug it and later add the new functionalities that I will like to add to it ?
Thanks

Hi guys, I was wondering how you would go about personalizing ROMs for your own use. Nothing code-wise, but installed programs and such. Opening up the zip files of downloaded ROMs I see the apk files and the system apk files - is it really as easy as just removing those you don't want and plotting in the ones that you do?
If this rom is from the same board as you, can say so.
But, .. you still need to run a linux terminal the code to sign the package that you previously made with same special files..
Just the search tools and you'll find it!
...You can easily too start porting rom's too...
Hi all,

Is there a way to compile .java file to .class file and execute it
I wanted to compile c/c++/java programs, not for my phone but in my phone...
I searched but did not find an easy way for it.
At last I found out a real easy way to compile c/c++ by using adosbox for android.
I copied the turbo c 'tc' folder from my pc to my sdcard and used adosbox like command promt to go to 'bin' folder in tc and start tc.exe...
Then I could easily write and compile programs just like i did on the pc
But still no luck for java programs...
I copied the reqired java folder and then used adosbox to run the command "javac file.java" but it said "This Program Cannot Be Run in DOS Mode"
So if there is any other way to compile java programs in my phone
please help
Thanx in advance
Try looking at Eclipse, although Eclipse is a large desktop IDE, it includes its own Java compiler written in Java (in the part called "JDT core"), and if (as I hope) that Java compiler is not copyrighted by Sun/Oracle, you (or someone else already maybe) may be able to compile that part of Eclipse into a "native" Dalvik/Android App.
Googling the issue, I see that others have been asking for an Android port of Eclipse too, so maybe there will be some momentum going for this soon.
Need easy tutorial of Jave and Xml, for android, for begninger. can any one help me, treat me as i have no knowledge of computer.
Hello! Sorry if this is the wrong place to post this I just registered to the forum!
To keep it short I am a frequent player of the game 'Idle Heroes' and I got the idea to take the APK, modify it (for private use of course) and give me resources in the game so I can try out different heroes etc etc.
So I read up on the APKtool and all that but I am having some trouble, I can't find the framework I need.. I am just getting errors when trying to decompile and I can't find any framwork in my phone or online to download..
Any help is appreciated! Thanks!
If it's any help I have a Galaxy S9 (not rooted)
For apk tool you need to write it in the following format in command prompt... (assuming you are using apk tool 2.2.4)
Java –jar apktool_2.2.4.jar d C:\<path to apk file>
But this would give you stuff like the android manifest. If you want the raw source code itself, you would need to use something such as dex2jar. Format is below.
d2j-dex2jar.bat C:\<path to apk file>

Thanks for your reply! Unfortunately I'm still struggling.. As you said it's the source code I am after. If you haven't played the game I'll try to explain what I am after.
Every day you get daily missions you can do, I'd like to simply change the rewards from let's say 1 summoning scroll to 1000 so that each day I can get 1000 scrolls, and I also want to change the other rewards to give me a couple of thousand gems instead of the 20 I get each day, that will give me enough to get the heroes I am after!
Would you care to help me a little more specifically on how to achieve this? Right now I have put the .apk in "C:\android\apktool" along with the apktool itself (apktool.jar).
But I don't have a .bat file, what kind of .bat file do I want to create? Also I don't have any other folders or such. And yes I have the newest version of Apktool!
No matter what I write in CMD it gives me an error, I don't have any framework files etc and I don't know where to get them.. I did also use the code you gave me (java -jar etc etc) but it also gave me errors .. If you'd like me to try something else and/or post the errors here I'd gladly do so!
Sorry for being such a noob but I have never done anything like this before, I recently started learning C++ but it's mainly simple games (for PC) in UE4 and stuff like that, but nothing for mobile.
Thanks a lot for your time!
