Скачать или смотреть Android Application Security Demo: Dalvik bytecode reverse engineering (Flappy Bird clone)

It is a quite simple to reverse engineer Dalvik bytecode, you need just APKTool and text editor. That is enough to modify ads IDs and credentials, get or modify API keys/logins/passwords and other sensitive information that is located in APKs. If an APK is not protected/obfuscated at all or if the only name obfuscation applied - it is a matter of minutes to make a clone of an application with different ads, inject a malicious code, and so on.

Want to know how to protect your applications from AntiLVL and reverse engineers? How to save it from being pirated or cloned? You might use DexProtector (http://dexprotector.com), best of breed protector and obfuscator for Android applications. It works straight with APKs, thus there is no need in any complicated integration with your build process.
