问题
Before this, I had asked a question about the CLIENT side in stackoverflow.com , there is no solution to the client side yet. So I am thinking maybe I can show the server side, make a comparison between these two side. FYI, currently testing on an android version 6.0.1 device.
Below is my code(SERVER):
public class MainActivity extends AppCompatActivity {
BluetoothAdapter mBluetoothAdapter;
IntentFilter mIntentFilter;
BroadcastReceiver mReceiver;
Intent discoverableIntent;
private BluetoothSocket socket;
private static final int DISCOVERABLE_REQUEST_CODE = 0x1;
public static final String NAME = "bluetoothComm";
public static final UUID MY_UUID = UUID.fromString("a60f35f0-b93a-11de-8a19-03002011c456");
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void turnOnBluetooth() {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, 1);
}
public void init(){
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
Toast.makeText(MainActivity.this, "Bluetooth is not supported in this device", Toast.LENGTH_SHORT).show();
finish();
}else {
if (!mBluetoothAdapter.isEnabled()) {
turnOnBluetooth();
}
}
discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
startActivityForResult(discoverableIntent, DISCOVERABLE_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
android.util.Log.e("TrackingFlow", "Creating thread to start listening...");
new Thread(reader).start();
}
private Runnable reader = new Runnable() {
public void run() {
try {
BluetoothServerSocket serverSocket = mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME, MY_UUID);
android.util.Log.e("TrackingFlow", "Listening...");
socket = serverSocket.accept();
android.util.Log.e("TrackingFlow", "Socket accepted...");
}catch (Exception e){
e.printStackTrace();
}
}
};
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(mReceiver);
}
}
Above codes will give me no error, however, the bluetooth socket is not accepting new request, although it started to listen for incoming request. Please make a comparison between these two sides. I had spent so much time to figure the solution out...someone please help me!
