Probleme mit der Verwendung von Device.getName () . Es ist aus irgendeinem Grund, dass meine Bewerbung zum Absturz gebracht wird. < /p>

Ich mache einen Adapter (Halten von Bluetooth -Namen) in einem Dialogfeld. Wenn ich die Anwendung ausführe und Geräte füge.[code]mBluetoothAdapter.startDiscovery();
receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();

if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

toothadapter.add(device.getName());
toothadapter.notifyDataSetChanged();
}
}
};
AlertDialog.Builder builder = new AlertDialog.Builder(bluetooth.this);
builder.setTitle("Nearby Devices:");
builder.setAdapter(toothadapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {

}
});
AlertDialog alert = builder.create();
alert.show();

IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(receiver, filter);
[/code]

benötigen wirklich Hilfe dafür, warum dies geschieht.>
