Need help with android studio
Hi there!
Trying to learn the very basic of this but been struggling really hard a couple of days now.

I have made up some simple buttons just to try its function but just get this result: "unfortunately, myCalculator has stopped" when pressing any button on the virtual device.







Another thing is that every time I run any virtual device my discspace reduces by somewhere around 500MB-1GB each time. Cant find any way to "clean" or restore that space..


1) You buttonClick() method should be buttonClick(View view).
2) As of your second problem, this is strange. Does your disc space remain in use even after the emulator is closed.
