When compiling the game on android, errors fly out, what's the problem?

Question

Android

I am learning programming. Implemented the movement of an object through the Joystick for android ..
But here is such a problem.
When I compile an empty project for android, everything is fine and without errors, but when I "make a game" and after I try to compile, then there are definitely some errors, and after them an endless download appears . This is weird.

Answer 1

It's because of the assets. Googled the error itself, should bring up a specific reason. Most likely this is due to the coincidence of some scripts or methods.
