How to handle notch(display cutout) in android API lower than 28?

Question

Android added notch support on API 28, but how to handle it on devices running API 27 (Honor 10, Huawei P20, etc.) ?

I was trying to use DisplayCutoutCompat<

Answer 1

Google provided notch related APIs in Android P. Devices with notch and API version lower than P implemented their own notch APIs.You can consult the APIs from device specified documentation.

Also I did not see creation of DisplayCutoutCompat instance in official documentation, but you can create DisplayCutout as follow:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
            DisplayCutout displayCutout = getWindow().getDecorView().getRootWindowInsets().getDisplayCutout();
}
