Android Question Encrypt Asset Files

See here: https://www.b4x.com/android/forum/threads/secured-assets-encrypt-your-assets-files.35589/

If you don't use the designer you can also use some subs (e.g. CreateEdittext, CreateLabel, etc.) to create the layout. The data for the views like top, left, width and height can then also be encrypted. Store the info in the asset folder, too. A bit of work but if someone wants to copy parts of your app, the layout isn't usable or it is hard to "hack".

Thank you Kmatle, one more question can i use this to encrypt also .json and .js files? thanks

There's a point that eludes me: to decrypt all that stuff you need to provide your code the password. If you store it in code, well, it's there. If you download it at runtime from a server, decompiling your code gives hints on how to download it anyway. So, how secret it's the secret?
You could adopt a steganography-like method to hide it, but will it suffice?
