I am writing instrumentation test cases of a method that checks the state of my android device. I am mocking the context for this statement:
BluetoothManager bluetoothManager = (BluetoothManager) context.getSystemService(Context.BLUETOOTH_SERVICE);
But upon reaching this statement it gives the following exception:
----- begin exception -----
