I have the same issue. From the official documentation:
As of API Level API level Build.VERSION_CODES.P only INTERSECT and DIFFERENCE are valid Region.Op parameters.
The issue is in FrissonView.java at line 226: canvas.clipRect(viewBounds, Region.Op.UNION);
As you can see the region is set to UNION which is removed since Android 9.0 P.
What I did is I added an if statement inside FrissonView.java, to check which Android version the phone is running and set the Region.Op according to it.
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.P) {
canvas.clipRect(viewBounds, Region.Op.UNION)
} else {
canvas.clipRect(viewBounds)
}
The app doesn't crash anymore on 9.0 devices but the waves from the view are a bit messed up, so this is not a perfect solution, more like a temporary fix.
I have the same problem... i hope this issue can fix...
