Android Geofence Transition PendingIntent似乎未運行（反應本機橋）

Question

我正在按照android guide android guide來構建一個簡單的本機橋，用於geofencing的react-native。

但是進入或離開地理圍欄時我沒有任何反應。 似乎PendingIntent / IntentService for Transitions無法正常運行。

MyModule基本上看起來像這樣。 它還像在文檔中創建mGeofenceList一樣，其中填充了react-native的數據。

MyModule的：

public class MyModule extends ReactContextBaseJavaModule {  

  //Build geofences
  private GeofencingRequest getGeofencingRequest() {
    GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
    builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
    builder.addGeofences(mGeofenceList);
    return builder.build();
  }

  //Build pending intent
  private PendingIntent getGeofencePendingIntent() {
    // Reuse the PendingIntent if we already have it.
    if (mGeofencePendingIntent != null) {
      return mGeofencePendingIntent;
    }
    Intent intent = new Intent(reactContext, GeofenceTransitionsIntentService.class);
    // We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when
    // calling addGeofences() and removeGeofences().
    mGeofencePendingIntent = PendingIntent.getService(reactContext, 0, intent, PendingIntent.
            FLAG_UPDATE_CURRENT);
    return mGeofencePendingIntent;
  }

  @ReactMethod
  public void startMonitoring() {
    mGeofencingClient.addGeofences(getGeofencingRequest(), getGeofencePendingIntent())
      .addOnSuccessListener(new OnSuccessListener<Void>() {
        @Override
        public void onSuccess(Void aVoid) {
          Log.i(TAG, "Start Monitoring");
          postNotification("Start Monitoring", "Pressed Start Monitoring");
        }
      })
      .addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
          Log.e(TAG, "Start Monitoring: " + e.getMessage());
        }
      });
  }
}

運行startMonitoring() ，將生成通知（“開始監視”）和日志，因此我認為該部分中沒有錯誤。

IntentService看起來也很基本/類似於文檔。 IntentService：

public class GeofenceTransitionsIntentService extends IntentService {
    private static final String TAG = "GeofenceService";
    private Handler handler;
    SharedPreferences sp;

    public GeofenceTransitionsIntentService(){
        super(TAG);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        sp = PreferenceManager.getDefaultSharedPreferences(this);
        handler = new Handler();
        Log.i(TAG, "Intent created");
    }


    protected void onHandleIntent(Intent intent) {
        Log.i(TAG, "onHandleIntent");
        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
        if (geofencingEvent.hasError()) {
            String errorMessage = "Error Code: " + String.valueOf(geofencingEvent.getErrorCode());
            Log.e(TAG, errorMessage);
            return;
        }

        // Get the transition type.
        int geofenceTransition = geofencingEvent.getGeofenceTransition();

        // Test that the reported transition was of interest.
        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER ||
                geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {

            // Get the geofences that were triggered. A single event can trigger
            // multiple geofences.
            List<Geofence> triggeringGeofences = geofencingEvent.getTriggeringGeofences();

            // Get the transition details as a String.
            String geofenceTransitionDetails = getGeofenceTransitionDetails(
                    geofenceTransition,
                    triggeringGeofences
            );

            // Send notification and log the transition details.
            //sendNotification(geofenceTransitionDetails);
            handler.post(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(getApplicationContext(), "Enter/Exit", Toast.LENGTH_SHORT).show();
                }
            });
            Log.i(TAG, geofenceTransitionDetails);
        } else {
            // Log the error.
            Log.e(TAG, "Invalid transition");
            handler.post(new Runnable() {
                @Override
                public void run() {
                    Toast.makeText(getApplicationContext(), "ERROR", Toast.LENGTH_SHORT).show();
                }
            });
        }
    }

    /*
        Helpfunctions for logging
     */
    private String getGeofenceTransitionDetails(
            int geofenceTransition,
            List<Geofence> triggeringGeofences) {

        String geofenceTransitionString = getTransitionString(geofenceTransition);

        // Get the Ids of each geofence that was triggered.
        ArrayList<String> triggeringGeofencesIdsList = new ArrayList<>();
        for (Geofence geofence : triggeringGeofences) {
            triggeringGeofencesIdsList.add(geofence.getRequestId());
        }
        String triggeringGeofencesIdsString = TextUtils.join(", ",  triggeringGeofencesIdsList);

        return geofenceTransitionString + ": " + triggeringGeofencesIdsString;
    }
    private String getTransitionString(int transitionType) {
        switch (transitionType) {
            case Geofence.GEOFENCE_TRANSITION_ENTER:
                return "entered Geofence";
            case Geofence.GEOFENCE_TRANSITION_EXIT:
                return "exit Geofence";
            default:
                return "unknown Transition";
        }
    }
}

但是此類的任何輸出都不會產生！

在本機模塊的清單中，我添加了權限：

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

在使用該模塊的TestApplication的清單中，我也添加了此權限，並在我添加的應用程序標簽中

<service android:name="com.mymodule.GeofenceTransitionsIntentService" android:exported="false"/>

我無法在模塊清單中添加最后一行，因為它缺少應用程序標簽並且沒有活動。 我不確定這是否是正確的地方。

我正在模擬器中進行測試，並將位置更改為GPS數據播放列表。

問題

1. 如何驗證ServiceIntent是否正在運行？ 我可以得到它的狀態嗎？
2. 日志出現在哪里？ 在com.TestApplication或其他地方？

當然：3.我的錯誤在哪里？

Answer 1

好吧，回答我自己的問題，或僅回答特定問題3：

上面的代碼沒有錯誤，或者至少沒有錯誤，並且可以在硬件設備上正常工作。

那么，如何在模擬器上正確調試Geofencing？
