Blue screen when build for android

I tried to build a game on android but the game only shows a blue screen, no error or stuff. Here is what I have tried:

  • Checking if the game contains any scene
  • Try to build a completed old game. I haven’t touched this game for months and the last time I build this game, it worked as intended. But this time, the only thing I did was press build and the game got a blue screen
  • Switch to a different platform. When I switch to PC, the game build as intended

So I think the problem relates to some Android thing, not the game itself. But I don’t know what causes it.

  • My minimum API build level: Android 4.1
  • Target API level: Automatic
  • SDK Tools Version: 26.1.1 (already tried using the 25.x.x but still got the same problem)
  • SDK Platforms installed: Android 9+ (API 29), Android 4.1 (API 16)

I think you need to change the software.
