Since AndroidStudio update 2.2, it takes a very long time for my native code app to start (I see a blank screen for ~20sec).
My guess is that it's because it takes a long time for the c++ debugger to settle.
Is its possible to disable it (and use only the good old java debugger)?
I just had the same problem. You can edit your "Run/Debug Configuration" for the project. In the "Debugger" tab change "Debug type" from 'auto' to 'Java'. Solved it for me.
