Question

我在使用Intent传递arrayList时遇到问题。当搜索完成并运行ACTION_DISCOVERY_FINISHED时，应用程序就会停止运行。

DesafioActivity：（发送者）

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {

        public void onReceive(Context context, Intent intent) {         
            String action = intent.getAction();

            if (BluetoothAdapter.ACTION_DISCOVERY_STARTED.equals(action)) {
                mDeviceList = new ArrayList<BluetoothDevice>();

                mProgressDlg.show();
            } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
                mProgressDlg.dismiss();

                Intent newIntent = new Intent(DesafioActivity.this, DeviceListActivity.class);

                newIntent.putParcelableArrayListExtra("device.list", mDeviceList);

                startActivity(newIntent);
            } else if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                BluetoothDevice device = (BluetoothDevice) intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

                mDeviceList.add(device);

                showToast("Dispositivo Encontrado " + device.getName());
            }
        }
    };

DevicesListActivity;（接收机）

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_paired_devices);

    mDeviceList = getIntent().getExtras().getParcelableArrayList("device.list");

    mListView = (ListView) findViewById(R.id.lv_paired);

    mAdapter = new DeviceListAdapter(this);

    mAdapter.setData(mDeviceList);
    mAdapter.setListener(new DeviceListAdapter.OnPairButtonClickListener() {
        @Override
        public void onPairButtonClick(int position) {
            BluetoothDevice device = mDeviceList.get(position);

            if (device.getBondState() == BluetoothDevice.BOND_BONDED) {
                unpairDevice(device);
            } else {
                showToast("Pairing...");

                pairDevice(device);
            }
        }
    });

logcat的：
