Android security for apk

I'm developing an android application for my client. He wants me to submit the apk to him for testing. I almost finished the application and i want to implement some kind of security to make sure that my client doesn't cheat me, until the payment is done.

Is there any way to implement any kind of security in the code?

I have compiled almost all security vulnerabilities and what measures to take before submitting your application to the play store. You can have a look here.

This library on github called AndroidTimeLock might be useful. It's specifically designed for sending a dev/test build that will expire and stop working. Of course if the person in question is technical and determined they could decompile the app, remove the timelock check and recompile.

Adding code obfuscation proguard (or as I prefer the paid DexGuard) would of course increase the difficulty of this.

You can make your core code builded a dex-format file.Then use some algorithms such as RC5 and others to encrypt your dex file.At last ,put the dex file in Asset file.Then when your project need the core code,you can dynmic loading/.

If you just need to send him/her the apk, you should obfuscate your source code . You can refer to this link——http://developer.android.com/tools/help/proguard.html，If you have finished it ,you needn't worry too much since the source code is in your hand and it's hard to get the source code by reserving. Besides your project has not finished . Last, even if your project is finished , it still works.

Did you ever hear of Proguard? This feature that you want is called Code obfuscation. Like pointed out in the comments, this is a duplicated question.
