connection between two android phones
- by user1770346
I m not able to connect my android device to other device(either android or non-android)via bluetooth.After detecting the devices from my android phone,i m not able to connect it to selected device from the list.The main problem is it not showing connectivity conformation message in selected device from list.How can i recover from this problem.
please help me.Thanks
My code for searching device is:(BluetoothSearchActivity.java)
public class BluetoothSearchActivity extends Activity {
ArrayAdapter<String> btArrayAdapter;
BluetoothAdapter mBluetoothAdapter;
TextView stateBluetooth;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ImageView BluetoothSearchImageView=new ImageView(this);
BluetoothSearchImageView.setImageResource(R.drawable.inner1);
setContentView(BluetoothSearchImageView);
setContentView(R.layout.activity_bluetooth_search);
mBluetoothAdapter=BluetoothAdapter.getDefaultAdapter();
ListView listDevicesFound=(ListView) findViewById(R.id.myList);
btArrayAdapter=new ArrayAdapter<String> (BluetoothSearchActivity.this,android.R.layout.simple_list_item_1);
listDevicesFound.setAdapter(btArrayAdapter);
registerReceiver(ActionFoundReceiver,new IntentFilter(BluetoothDevice.ACTION_FOUND));
btArrayAdapter.clear();
mBluetoothAdapter.startDiscovery();
listDevicesFound.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent,View view,int position,long id) {
Intent i6=new Intent(getApplicationContext(),AcceptThread.class);
startActivity(i6);
}
});
}
private final BroadcastReceiver ActionFoundReceiver=new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String action=intent.getAction();
if(BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device=intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
btArrayAdapter.add(device.getName()+"\n"+device.getAddress());
btArrayAdapter.notifyDataSetChanged();
Log.d("BluetoothSearchActivity",device.getName()+"\n"+device.getAddress());
}
}
};
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(ActionFoundReceiver);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_bluetooth_search, menu);
return true;
}
}
and my connectivity code is:(AcceptThread.java)
class ConnectThread extends Thread {
private static final UUID MY_UUID=UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66");
private static final String ConnectThread = null;
BluetoothSocket mSocket;
BluetoothDevice mDevice;
BluetoothAdapter mBluetoothAdapter;
public ConnectThread(BluetoothDevice device) {
BluetoothSocket temp=null;
mDevice=device;
try{
temp=mDevice.createRfcommSocketToServiceRecord(MY_UUID);
}catch(IOException e) { }
mSocket=temp;
}
public void run() {
mBluetoothAdapter.cancelDiscovery();
try{
Log.i(ConnectThread,"starting to connect");
mSocket.connect();
}catch(IOException connectException) {
Log.e(ConnectThread,"connection Failed");
try{
mSocket.close();
}catch(IOException closeException){ }
return;
}
}
public void cancel() {
try{
mSocket.close();
}catch(IOException e) { }
}
}
public class AcceptThread extends Thread{
private static final String NAME="BluetoothAcceptThread";
private static final UUID MY_UUID=UUID.fromString("fa87c0d0-afac-11de-8a39-0800200c9a66");
BluetoothServerSocket mServerSocket;
BluetoothAdapter mBluetoothAdapter;
public AcceptThread() {
BluetoothServerSocket temp=null;
try{
temp=mBluetoothAdapter.listenUsingRfcommWithServiceRecord(NAME,MY_UUID);
}catch(IOException e){ }
mServerSocket=temp;
}
public void run() {
BluetoothSocket socket=null;
while(true) {
try{
socket=mServerSocket.accept();
}catch(IOException e) {
break;
}
if(socket!=null) {
try {
mServerSocket.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
}
}
}
public void cancel() {
try{
mServerSocket.close();
}catch(IOException e) { }
}
}
