未从 Android 地理围栏事件收到 Intent

【中文标题】未从 Android 地理围栏事件收到 Intent

【英文标题】：Intent not received from Android Geofence event

【问题描述】：

一切都正确构建并在模拟器中运行，但我似乎无法让我的 IntentService 记录任何内容。我敢肯定，我缺少或忽略了一些基本的东西，但我对 android/Java 还是很陌生，目前已经没有什么想法了。

public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener 

private Geofence geofence;
private PendingIntent mGeofencePendingIntent;
private GoogleApiClient mGoogleApiClient;

@Override
protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    LatLng latLng = new LatLng(39.7492350, -104.9913250);

    geofence = new Geofence.Builder()
            .setRequestId(GEOFENCE_REQ_ID)
            .setCircularRegion(latLng.latitude, latLng.longitude, GEOFENCE_RADIUS_IN_METERS)
            .setExpirationDuration(GEOFENCE_EXPIRATION)
            .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT)
            .build();

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
    mGoogleApiClient.connect();


private boolean checkPermission() 
    Log.i(TAG, "MainActivity.checkPermission()");
    return (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);


private GeofencingRequest getGeofencingRequest() 
    Log.i(TAG, "MainActivity.getGeofencingRequest()");
    GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
    builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
    builder.addGeofence(geofence);
    return builder.build();


private PendingIntent getGeofencePendingIntent() 
    Log.i(TAG, "MainActivity.getGeofencePendingIntent()");
    if (null != mGeofencePendingIntent) 
        return mGeofencePendingIntent;
    

    Intent intent = new Intent(this, GeofenceTransitionsIntentService.class);
    return PendingIntent.getService(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);


@Override
public void onConnected(Bundle connectionHint) 
    Log.i(TAG, "MainActivity.onConnected()");
    if (checkPermission()) 
        mGeofencePendingIntent = getGeofencePendingIntent();
        LocationServices.GeofencingApi.addGeofences(mGoogleApiClient, getGeofencingRequest(), mGeofencePendingIntent);
     else 
        Log.i(TAG, "Permission not granted");
    


@Override
public void onConnectionSuspended(int i) 
    Log.i(TAG, "MainActivity.onConnectionSuspended()");
    if (null != mGeofencePendingIntent) 
        LocationServices.GeofencingApi.removeGeofences(mGoogleApiClient, mGeofencePendingIntent);
    


@Override
public void onConnectionFailed(ConnectionResult connectionResult) 
    Log.i(TAG, "MainActivity.onConnectionFailed()");

每当我使用模拟器或 android 控制台更新该设备的 lat/lng 时，以下服务都不会收到任何意图：

public class GeofenceTransitionsIntentService extends IntentService 

public GeofenceTransitionsIntentService() 
    super(GeofenceTransitionsIntentService.class.getSimpleName());


@Override
protected void onHandleIntent(Intent intent) 
    Log.i(TAG, "GeofenceTransitionsIntentService.onHandleIntent()");

    GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
    if (geofencingEvent.hasError()) 
        int errorCode = geofencingEvent.getErrorCode();
        Log.e(TAG, "Location Services error: " + errorCode);
     else 
        Log.i(TAG, "geofencingEvent was successful");
    

清单：

<?xml version="1.0" encoding="utf-8"?>

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

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <service android:name=".GeofenceTransitionsIntentService" />
</application>

我一直在参考以下资源：Android Documentation 和 Google Sample。

【问题讨论】：

我有几件事您没有澄清：1-您是否在真实设备上对其进行了测试？ 2-你在指定的纬度/经度范围内吗？ 3-是否安装了 Google Play 服务？ 4-您是否尝试过打开谷歌地图然后更新纬度/经度？有时这是让 GPS 在模拟器上工作的唯一方法。

请在真机上运行你的应用，然后告诉。

【参考方案1】：

位置服务在模拟器中似乎没有完全发挥作用。插入真实设备后，一切都按预期工作。
