Android: Window surface is invalid after suspend |

Hi
I built testgesture.c for Android and installed it successfully: ./androidbuild.sh org.libsdl.testgesture ../test/testgesture.c cd ../build/org.libsdl.testgesture/ ant debug install The testgesture application works as intended, but when I put my devices[1] in sleep mode and awake them after, the application can no longer update the screen (whatever has been on the screen before is still there). The rest of the application however still works (events come in and get proceeded). Changing the device from landscape to portrait mode fixes the problem. I noticed that the return value of SDL_UpdateWindowSurface()[2] in DrawScreen() is -1 after a resume and the output of SDL_GetError() is the following: Window surface is invalid, please call SDL_GetWindowSurface() to get a new surface Calling SDL_GetWindowSurface() indeed allows the screen to "come back" to life. However, I do not think that this is a good fix for this problem. Any recommendation?
