[Interest] android: how to check if java native method is defined?

[Alexander Dyagilev]

Hello,

I have a broadcast receiver registered in manifest.

It executes native method.

The problem that if the main activity is not running, i'm getting 
zygote  : No implementation found error and my app crashes.

Is there a way to check if native method is defined. I would like to 
just not do anything in case it is not.
