I wanna ask how to edit apk files and how to view source script inside with android aplications

Answer 1

it is very hard, because .apk files are compiled so you can't just simply change something like for example in the browser console

however it is possible to decompile -> change something -> compile again but you won't be able to change everything

what you could do is:

change icons/images
change the library's

if your a pro (but then you wouldn't probably ask) you could attempt to read the source code in java format

there are various apps out which will help you with this task, however I won't provide any links, you can google it yourself😉

Answer 2

There's an app named 'Show Java' in Google Play Store. It can be used to retrieve both XML and Java code of an Android app.

Answer 3

What you want to do is called reverse engineering and you can use tools like apktool and dex2jar to extract the sources from apk. This link gives full step by step description to do so.

Answer 4
