Android Bluetooth StartDiscovery() always returns false
问题 I am trying to discover bluetooth devices nearby, but startDiscovery() always returns false, as if it is not working. Therefore it is not able to find devices. I saw that i have to include Coarse_Location permission apart from Bluetooth and Bluetooth_Admin, but anyway, it doesn´t work. Here is the code I am trying right now, where there are mainly traces to see how it works: public class BluetoothActivity extends AppCompatActivity { RecyclerView recyclerView; ArrayList<BluetoothDevice>
