我正在尝试创建一个 android 应用程序来使用 Gimbal sdk 检测基于 Gimbal 的信标，但我的应用程序无法检测到信标。但是如果我尝试使用 BluetoothGATT，我可以检测到信标。以下是我的代码中侦听信标事件的部分。API 密钥验证成功，但仍然无法显示接近度。
public class MainActivity extends Activity {
private PlaceManager placeManager;
private PlaceEventListener placeEventListener;
private BeaconEventListener beaconEventListener;
private BeaconManager beaconManager;
private String TAG = "beacon";
public ArrayAdapter<String> listAdapter;
public ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
Gimbal.setApiKey(getApplication(),
"MY API KEY ");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
monitorPlace();
listenBeacon();
CommunicationManager.getInstance().startReceivingCommunications();
}
private void listenBeacon() {
BeaconEventListener beaconEventListener = getBeaconEventListener();
BeaconManager beaconManager = new BeaconManager();
beaconManager.addListener(beaconEventListener);
beaconManager.startListening();
}
private void monitorPlace() {
placeEventListener = getPlaceEventListener();
// placeManager = PlaceManager.getInstance();
// placeManager.addListener(placeEventListener);
placeManager = PlaceManager.getInstance();
placeManager.addListener(placeEventListener);
placeManager.startMonitoring();
}
private void initView() {
GimbalLogConfig.enableUncaughtExceptionLogging();
listAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_expandable_list_item_1);
listView = (ListView) findViewById(R.id.list);
listView.setAdapter(listAdapter);
listAdapter.add(" Gimbal API Key got Set Successfuly");
listAdapter.notifyDataSetChanged();
GimbalDebugger.enableBeaconSightingsLogging();
