I cannot do anything because of the error log popping up with empty error messages. Please help me.

Details

I have connected a samsung device and install kies driver software, and this happened after I tried to test the application on the real device.

Any help would be appreciated. Thanks in advance !

Answer 1

Try switching to a new window.

Just right click on any of the file names on the top menu, and click on "new window".

Answer 2

Seems to be a problem with the render target of API 19. Try changing the render target to something lower than 19, e.g. 18. (That's the little Android symbol with the number and the dropdown arrow above the rendered layout.) It fixed the issue for me.
