Android 土工栅栏不触发

我正在尝试在我的应用程序上实现

地理围栏

，问题是当我在标记的位置时，它不会触发

我要做的是从一个角度设置

纬度

&

经度

我得到的值很好，因为我把它放在上面，位置是正确的，因为我读过很多答案，人们从lat/long设置了不好的值

我有两个类：

GeofenceSingleton.class

和

GeofenceTransitionsIntentService

GeofenceSingleton.class

如下所示：

public class GeofenceSingleton implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<Status> {

private GoogleApiClient googleApiClient;
private static GeofenceSingleton _singleInstance;
private static Context appContext;
private static final String ERR_MSG = "Application Context is not set!! " +
        "Please call GeofenceSngleton.init() with proper application context";
private PendingIntent mGeofencePendingIntent;
private static ArrayList<Geofence> mGeofenceList;


private GeofenceSingleton() {
    if (appContext == null)
        throw new IllegalStateException(ERR_MSG);

    this.googleApiClient = new GoogleApiClient.Builder(this.appContext)
            .addApi(LocationServices.API)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
    this.googleApiClient.connect();
    mGeofenceList = new ArrayList<Geofence>();
}

/**
 * @param applicationContext
 */
public static void init(Context applicationContext) {
    appContext = applicationContext;
}

public static GeofenceSingleton getInstance() {
    if (_singleInstance == null)
        synchronized (GeofenceSingleton.class) {
            if (_singleInstance == null)
                _singleInstance = new GeofenceSingleton();
        }
    return _singleInstance;
}

@Override
public void onConnected(Bundle bundle) {

}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}

public void addGeofence(Location location, String uid) {
    mGeofenceList.add(new Geofence.Builder()
            .setRequestId(uid)
            .setCircularRegion(
                    location.getLatitude(),
                    location.getLongitude(),
                    500
            )
            .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
            .setExpirationDuration(1000000)
            .build());
}

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

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

public void startGeofencing() {
    if (!googleApiClient.isConnected()) {
        Toast.makeText(appContext, "API client not connected", Toast.LENGTH_SHORT).show();
        return;
    }

    LocationServices.GeofencingApi.addGeofences(
            googleApiClient,
     // 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()
    ).setResultCallback(this); // Result processed in onResult().
    Toast.makeText(appContext,"Geofencing started", Toast.LENGTH_LONG).show();
}



public void removeGeofence(){
    LocationServices.GeofencingApi.removeGeofences(
            googleApiClient,
// This is the same pending intent that was used in addGeofences().
            getGeofencePendingIntent()
    );
}

@Override
public void onResult(Status status) {
    if (status.isSuccess()) {
// Update state and save in shared preferences.

        Toast.makeText(
                appContext,
                "YO",
                Toast.LENGTH_SHORT
        ).show();
    } else {
        Toast.makeText(
                appContext,
                "NOO",
                Toast.LENGTH_SHORT
        ).show();
    }
}
}

在我的

main活动中

GeofenceSingleton.init(this); //If I don't call this the class doesn't work
this.geofenceSingleton = GeofenceSingleton.getInstance();

然后我构建了一个

地理围栏

，如下所示：

Location geofence = new Location("");
geofence.setLatitude(Double.parseDouble(latitude));
geofence.setLongitude(Double.parseDouble(longitude));
geofenceSingleton.addGeofence(geofence, GeofenceKey);
geofenceSingleton.startGeofencing();

笔记 我已经在我的

manifest.xml

我将

服务

声明为

我在我的

build.gradle

：

compile'com.google.android.gms:play services:7.8.0'

它只显示

Toast.makeText（appContext，“YO”，Toast.LENGTH_SHORT）.show（）这是因为状态是success，并且还显示了
Toast.makeText（appContext，“geobinging start”，Toast.LENGTH_LONG）.show（）表示它已启动

问题:
为什么从未调用my
IntentService

我在我家放了一个
Lat
/
Long
，对它进行了测试，既然我在上面，它应该会被触发，不是吗？
正如我已经回答的，
Geofence API
有点像被动定位接收器，也就是说，当您需要
地理围栏
工作时，您必须同时从
LocationServices.FusedLocationApi.RequestLocationUpdate
请求坐标。
它永远不会工作，因为您所做的是

Intent intent = new Intent(appContext, GeofenceSingleton.class);

将意向传递给单身汉

你需要做的是

Intent intent = new Intent(appContext, GeofenceTransitionsIntentService.class);

如果您的意图已使用适当的类构造（请参阅），则还需要确保服务也包含在
AndroidManifest.xml
中

<application
    ...

    <service android:name=".GeofencingTransitionIntentService" />

确保您的服务和广播接收在清单中启用了这些属性

  android:enabled="true"
  android:exported="true"

工作正常吗？顺便说一句，我用这3个文件创建了一个新项目，然后试着去做，结果成功了，所以我也会为你工作。@Skizo ozᴉʞS我可以获得进入通知，但无法获得退出通知FIRED@Skizo-奥兹ᴉʞS同样，当我给出的半径小于25米时，我没有收到进入通知。知道它为什么不工作吗？？？退出通知不会被触发，因为您已经设置了TransitionTypes（Geofence.Geofence_TRANSITION_ENTER）您还需要添加GEOFENCE\u TRANSITION\u ENTER以获得退出转换。您不需要分配权限吗？您要导出它吗？
  android:enabled="true"
  android:exported="true"
