Here is my problem/question, probably a nooby one....
I have an activity where the app checks if the bluetooth is switched on, if not it displays a pop-up window with a button to activate it.
when activated there is a button which will search for bluetooth devices.
now my question is how can i pair to the selected device which will be protected with an password, if it is already paired just connect to it (witouth entering the password again)
after connecting to the device it should go to the next page.
Here is my Code
package com.example.silcamanager96x32;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;

import android.widget.AdapterView.OnItemClickListener;
public class Bluetooth_check extends Activity {
//global variables
private final static int REQUEST_ENABLE_BT = 1;
private ArrayAdapter<String> btArrayAdapter;
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_bluetooth_check);
btn_go();
btn_scan();
}
//tijdelijke button volgende pagina
public void btn_go(){

btn_go.setOnClickListener(new OnClickListener() {
@Override

// TODO Auto-generated method stub
Log.i("clicks","You Clicked B1");
Intent i=new Intent(
Bluetooth_check.this,
home.class);
startActivity(i);
}
});
}
//button scannen naar bluetooth apparaten en in ene lijst plaatsen
public void btn_scan(){
final Button scanb = (Button)findViewById(R.id.button);
final ListView Deviceslist = (ListView)findViewById(R.id.listView1);

//vraagt of app bluetooth mag inschakelen

if (mBluetoothAdapter == null) {
// Device does not support Bluetooth
Toast.makeText(Bluetooth_check.this, "Your device doesnot support Bluetooth", Toast.LENGTH_LONG).show();
}
if (!mBluetoothAdapter.isEnabled()) {
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
//onclick scan button
scanb.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{

}
});

// onclick item gevonden apparaten
AlertDialog.Builder adb = new AlertDialog.Builder(
Bluetooth_check.this);
adb.setTitle("ListView OnClick");
adb.setMessage("Selected Item is = "
+ Deviceslist.getItemAtPosition(position));
adb.setPositiveButton("Ok", null);
adb.show();
}
});
registerReceiver(FoundReceiver, new IntentFilter(BluetoothDevice.ACTION_FOUND));
}
@Override
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
unregisterReceiver(FoundReceiver);
}
private final BroadcastReceiver FoundReceiver = 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();
}
}};
}
