Have followed instructions to the letter, watched numerous tutorials & still no answer after five days of trying. When I run any app(even the simple example) I get the title but just a black screen. No message box appears. I've installed everything that was stated, I've uninstalled and clean installed numerous time. I ran the app in "debug" mode & "compile & run" mode with the same result. I've also tried numerous example apps all with same result, I've also created a layout and generated members but still the same. I'm using a Samsung A5 phone. Any help would be appreciated, there doesn't seem to be any reason why this won't work.
