Check if android device has 'Draw over other app's' feature

Question

I require the 'Draw over other apps' functionality to launch my activity from the background at a specific period. This works well on some devices, however I am testing it on a Samsung A01 device with Android 10 and the feature isn't available.

Is there a way I can check if the feature is available?

Answer 1

Actually I came to learn that the feature doesn't exists on Android Go devices.

Using the method isLowRamDevice() from ActivityManager, I was able to tell whether or not the device supports the feature.

How it works

ActivityManager activityManager = (ActivityManager) getContext().getSystemService(ACTIVITY_SERVICE);
boolean drawOverOtherAppsFeatureAvailable = activityManager.isLowRamDevice();
