尽管在清单文件中指定了权限，但是ACCESS_FINE_LOCATION SecurityException。

My app is attempting to access the device's location and I have included the following in the AndroidManifest.xml:

我的应用程序正在尝试访问设备的位置，我在AndroidManifest.xml中包含了以下内容:

<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>

I have implemented the GoogleApiClient.ConnectionCallbacks as follows to access the location service:

我实现了GoogleApiClient。连接回调如下，以访问位置服务:

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 void onConnectionSuspended(int i) {
        Log.i(TAG, Integer.toString(i));
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        Log.i(TAG, connectionResult.toString());
    }
}

When I trigger the location service call, the following exception is thrown:

当我触发位置服务调用时，抛出以下异常:

java.lang.SecurityException: Client must have ACCESS_FINE_LOCATION permission to request PRIORITY_HIGH_ACCURACY locations.

I am using an actual device to produce this issue and have been scratching my head on why the exception is thrown.

我正在使用一个实际的设备来产生这个问题，并且一直在思考为什么会抛出异常。

The issue was caused by a new feature for Android 6.0.

这个问题是由Android 6.0的一个新特性引起的。

Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app.

从Android 6.0 (API级别23)开始，用户在应用程序运行时授予应用程序权限，而不是在安装应用程序时授予。

http://developer.android.com/training/permissions/requesting.html

To get around the issue when the permission is not explicitly granted, I had put in a check to wrap location service calls (as per the Google Documentation, slightly modified).

为了避免未显式地授予权限时的问题，我进行了一个检查，以包装位置服务调用(根据谷歌文档，稍微修改)。

int permissionCheck = ContextCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION);

if (permissionCheck == PackageManager.PERMISSION_GRANTED) {
    //Execute location service call if user has explicitly granted ACCESS_FINE_LOCATION..
}

The Google Documentation also steps through how to request for the permissions that are needed.

谷歌文档还介绍了如何请求所需的权限。

Adding in @Siddharth's update to include a more helpful answer for checkSelfPermission()

在@Siddharth的更新中添加一个对checkSelfPermission()更有帮助的答案

//For this example, run the check onResume()
@Override
public void onResume() {

    if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED) {

        // Should we show an explanation?
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.ACCESS_FINE_LOCATION)) {

            // Show an expanation to the user *asynchronously* -- don't block
            // this thread waiting for the user's response! After the user
            // sees the explanation, try again to request the permission.

        } else {

            // No explanation needed, we can request the permission.
            // PERMISSION_REQUEST_ACCESS_FINE_LOCATION can be any unique int
            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_ACCESS_FINE_LOCATION);
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case PERMISSION_REQUEST_ACCESS_FINE_LOCATION: {
            // If request is cancelled, the result arrays are empty.
            if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted, yay! Do the
                // contacts-related task you need to do.

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.
            }
            return;
        }

        // other 'case' lines to check for other
        // permissions this app might request
    }
}
