I'm working on ads: my customers gave me some APK files of their Apps.
My work consists of inserting ad banners into them.
After closing the ad banners, these apps will run.
My question is: How to decode and decompile APK file?
Usman Kurd
To decompile APK Use APKTool.
You can learn how APKTool works on http://www.decompileandroid.com/ or by reading the documentation.
You can try this website http://www.decompileandroid.com Just upload the .apk file and rest of it will be done by this site.
