Use this function to check if a permission is granted to perform a specific operation. The permissions are idenfified with the string constants declared in the Manifest.permission package:
void setup() { requestPermission("android.permission.ACCESS_FINE_LOCATION"); } void draw() { if (hasPermission("android.permission.ACCESS_FINE_LOCATION")) { text("Location is available", width/2, height/2); } else { println("No permission to read location", width/2, height/2); } }
