I think that it is due to the copy cats that keep stealing apps and repacking them.

Most Android developers lack native coding experience, so after failing attempts to protect their applications with the DEX bytecodes obfuscator, they think that recoding parts of the application with the NDK will save them.

However as this article shows, and most here know, they shortly learn that against good attackers, the only benefit from using native code directly is it takes a little longer to decipher what the application does.

So then one turns to solutions like what you are describing.

Yeah like that one app I reversed a while ago that generated the API key in a native library. I was able to get the key by building my own app around their library and calling the function that returns the key. Didn't even have to disassemble the thing.
