AGK 2.21 crashes on Android if you call the advert system after loading a shader that doesn't exist or has a miss-spelled filename. The app displays a black screen for a long time after closing the ad; sometimes the advert content is corrupted with blocks of colour. Eventually the app will just exit.
The app resumes correctly if the .apk type is set to 'Google'
Good news: SetErrorMode(2) will catch the error but I missed it for a while because I was setting that
after I'd tried to load the shader.
Setting Error Mode to 0 before trying to load a non-existent shader results in a message box that reads "Vertex shader failed to compile: 0:1: L0009: Missing main() function for shader."
Bad news: The crash is silent if you try to load the shader or ads before calling SetErrorMode(). Good thing we have GetLastError() otherwise I might not have found it. Bottom line: Have SetErrorMode() as one of the first lines in your code!
Media-free test code;
- Populate with your own ad credentials
- Export .apk with APK Type set to Amazon
- Run app and wait for "btnRed AdvertLoadedAdMob(): 0" to change to 1.
- Press the red rectangle to show the ad.
- Ad will display with graphics corruption; closing the ad results in a crash.
