Trying to get a reverse connection using msf venom on android 4.x.
The apk i have generated crashes after sending initial connection to the listener.
any ideas?

If you have adb, you can try attaching a usb debug session to get a stack trace. You might also find that in the syslog.
If you can provide a stack trace and the source code I can help you figure out what's going on.

Usuallly with network application crashes, they're in socket code that doesn't have proper error handling. My guess is you're writing data to a socket that's not open (tcp), or you don't have permission to send data (udp)
