Android Geofence Transition PendingIntent似乎没有运行(反应本地桥接)

Question

我遵循android指南android指南为react native for geofencing构建一个简单的原生桥接。

但我在进入或离开地理围栏时没有得到任何回应。转换的PendingIntent/IntentService似乎没有正常运行。

MyModule基本上是这样的。它还创建了mGeofenceList，就像在填充了来自react native的数据的文档中一样。

MyModule：

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());
}
});
}
}

当运行startMonitoring()时，会生成通知(启动监视)和日志，所以我认为错误不在这一部分。

IntentService看起来也非常基本/类似于文档。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";
}
}
}

但是这个类的输出都没有产生

在本机模块的清单中，我添加了权限：

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

在使用该模块的TestApplication的清单中，我也添加了该权限，并在应用程序标签中添加了

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

我无法在模块的清单中添加最后一行，因为它缺少应用程序标记并且没有活动。我不确定这个地方是否合适。

我正在模拟器中进行测试，并将位置更改为GPS数据播放列表。

问题

1. 如何验证ServiceIntent是否正在运行？我能得到它的状态吗
2. 日志显示在哪里？在com.TestApplication或其他地方

当然：3.我的错误在哪里？

Answer 1

好的，回答我自己的问题，或者只回答特定的问题3:

上面的代码没有错误，或者至少在硬件设备上可以正常工作。

那么，如何在模拟器上正确调试Geofencing呢？
