Should you code obfuscate?
Code Obfuscation is safe. But still I would recommend you to first test your app compiled with obfuscated code before releasing it. Also, while testing before production should be done without obfuscation, as obfuscation is very time consuming many times. Your obfuscated code will be safer, but not safest.
