How to avoid reverse engineering of an APK file?

Question

I am developing a payment processing app for Android, and I want to prevent a hacker from accessing any resources, assets or source code from the APK file.<

Answer 1

There is no way to completely avoid reverse engineering of an APK. To protect application assets, resources, you can use encryption.

• Encryption will make harder to use it without decryption.choosing some strong encryption algorithm will make cracking harder.
• Adding some spoof code into your main logic to make more harder for cracking.
• If you can write your critical logic in any native language and that surely make harder for decompile.
• Using any third party security frameworks like Quixxi
