Track which application send toast message.
After I switched my phone form iPhone to Android (Google Pixel Phone), I found there are always some Toast notifications appear on the screen. Pic 1 is an example I usually met.
In the Android framework, Accessibility API can provide the possibility that can access the Toast message.
