我的应用正在尝试访问设备的位置,我在以下内容中包含以下内容AndroidManifest.xml:

<manifest 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.app">
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

    <application>
        <meta-data android:name="com.google.android.gms.version" />
    </application>

</manifest>

我已实现GoogleApiClient.ConnectionCallbacks如下访问位置服务:

public class BackgroundLocationService implements
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {

    private static final String TAG = BackgroundLocationService.class.getSimpleName();

    private static GoogleApiClient googleApiClient;
    private static PendingIntent locationCallback;

    public static int LOCATION_INTERVAL = 10000;
    public static int FAST_INTERVAL = 5000;

    @Override
    public void onConnected(Bundle bundle) {
        Log.i(TAG, "Connected to Google API");

        LocationRequest request = new LocationRequest();
        request.setInterval(LOCATION_INTERVAL);
        request.setFastestInterval(FAST_INTERVAL);
        request.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient, request, locationCallback);
    }

    @Override
    public …

A LocationSource在Google Maps Android API v2中定义.

它用于googlemap作为位置提供程序.默认情况下,位置源由手机上的gps模块提供.

但现在我想使用另一个Location source,位置数据将定期发送到Android设备.

我不知道如何实现这个接口.那里有什么例子吗？任何人都可以帮助我吗？该文件没有说明任何内容.

我想在启用my-location图层的Google地图上显示用户的位置,但此功能需要" ACCESS_FINE_LOCATION "权限才能从GPS获取位置.是否可以阻止GoogleMap尝试从GPS获取位置？

如果我删除了清单文件中的" ACCESS_FINE_LOCATION " 权限,一旦我尝试显示地图,该应用程序就会崩溃,并显示以下错误:
