[英]Unable to trigger geofence transition IntentService from PendingIntent
I want to dynamically update the list of geofences according to current location of user even when app is not in background. 我想根据用户当前位置动态更新地理围栏列表,即使应用不在后台。 So I am calling GeofencingApi.addGeofences from a service instead of activity. 因此,我从服务而不是活动中调用GeofencingApi.addGeofences 。
public void addGeofences()
{
if (!mGoogleApiClient.isConnected()) {
Log.v("TAG", getString(R.string.not_connected));
return;
}
try {
LocationServices.GeofencingApi.addGeofences(
mGoogleApiClient,
getGeofencingRequest(),
getGeofencePendingIntent(this)
).setResultCallback(this); // Result processed in onResult().
} catch (SecurityException securityException) {
logSecurityException(securityException);
}
}
Code to get PendingIntent: 获取PendingIntent的代码:
private PendingIntent getGeofencePendingIntent(Context c) {
if (mGeofencePendingIntent != null) {
return mGeofencePendingIntent;
}
Intent intent = new Intent(GeofenceService.this, GeofenceTransitionsIntentService.class);
return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
}
Code to get GeofencingRequest: 获取GeofencingRequest的代码:
private GeofencingRequest getGeofencingRequest() {
GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
builder.addGeofences(mGeofenceList);
return builder.build();
}
It does not trigger GeofenceTransitionsIntentService when user enters or exits a geofence. 用户进入或退出地理围栏时,它不会触发GeofenceTransitionsIntentService。 It works very fine when implemented in activity but it does not work from service. 在活动中实施时,它工作得很好,但不能从服务中工作。
Note: These functions are defined and called in a service which is dynamically changing mGeofenceList according to current location of user. 注意:这些函数是在服务中定义和调用的,该服务根据用户的当前位置动态更改mGeofenceList。

Following the example: https://developer.android.com/training/location/geofencing.html with code: https://github.com/googlesamples/android-play-location/tree/master/Geofencing 遵循示例: https : //developer.android.com/training/location/geofencing.html ,代码为: https : //github.com/googlesamples/android-play-location/tree/master/Geofencing
Use: 采用:
mGoogleApiClient.blockingConnect(TIME_OUT, TimeUnit.MILLISECONDS);
And add/change the code as following: 并添加/更改代码,如下所示:
public class RegisterGeoIntentService extends IntentService implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {
protected static final String TAG = "RegisterGeoIS";
private static final long TIME_OUT = 100;
protected GoogleApiClient mGoogleApiClient;
protected ArrayList<Geofence> mGeofenceList;
private PendingIntent mGeofencePendingIntent;
public RegisterGeoIntentService() {
super(TAG);
}
@Override
public void onCreate() {
super.onCreate();
Log.i(TAG, "Creating Intent service");
mGeofenceList = new ArrayList<Geofence>();
mGeofencePendingIntent = null;
}
@Override
protected void onHandleIntent(Intent intent) {
buildGoogleApiClient();
populateGeofenceList();
mGoogleApiClient.blockingConnect(TIME_OUT, TimeUnit.MILLISECONDS);
String connected = mGoogleApiClient.isConnected() ? "connected" : "disconnected";
Log.i(TAG, "Restoring geofence - status: " + connected);
addGeofencesButtonHandler();
}
...
public void addGeofencesButtonHandler() {
if (!mGoogleApiClient.isConnected()) {
Toast.makeText(this, getString(R.string.not_connected), Toast.LENGTH_SHORT).show();
return;
}
try {
LocationServices.GeofencingApi.addGeofences(
mGoogleApiClient,
// The GeofenceRequest object.
getGeofencingRequest(),
// A pending intent that that is reused when calling removeGeofences(). This
// pending intent is used to generate an intent when a matched geofence
// transition is observed.
getGeofencePendingIntent()
).await(TIME_OUT, TimeUnit.MILLISECONDS);
} catch (SecurityException securityException) {
// Catch exception generated if the app does not use ACCESS_FINE_LOCATION permission.
logSecurityException(securityException);
}
Log.i(TAG, "Trying to add Geofences - result: " + result.toString());
}
...
Add the following in AndroidManifest: 在AndroidManifest中添加以下内容:
<service android:name=".RegisterGeoIntentService" />
Call it with: 调用它:
Intent kickoff = new Intent(context, RegisterGeoIntentService.class);
context.startService(kickoff);
