Question

我最近在Android版6.0的设备上发生了一个问题

我遇到了以下崩溃

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

任何人都可以帮忙吗？

以下是可用于请求运行时权限的示例代码：

private static final int MY_PERMISSIONS_REQUEST_READ_FINE_LOCATION = 100;

和

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
            Manifest.permission.ACCESS_FINE_LOCATION)
    != PackageManager.PERMISSION_GRANTED &&
                    ContextCompat.checkSelfPermission( getApplicationContext(), android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)) {

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

      // Show an explanation 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.

      ActivityCompat.requestPermissions(thisActivity,
            new String[]{Manifest.permission.READ_CONTACTS},
            MY_PERMISSION_REQUEST_READ_FINE_LOCATION);

      // MY_PERMISSION_REQUEST_READ_FINE_LOCATION is an
      // app-defined int constant. The callback method gets the
      // result of the request.
   }
}

然后你可以在这里收到请求：

@Override
public void onRequestPermissionsResult(int requestCode,
    String permissions[], int[] grantResults) {
    switch (requestCode) {
    case MY_PERMISSION_REQUEST_READ_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
  }
 }

您可以在活动中轻松调用此功能，但我强烈建议您在此处阅读documentation以获得更好的主意。

我希望这有帮助！

如果这些权限已经在AndroidManifest.xml文件中，请在应用级build.gradle文件中将targetSdkVersion设置为 22 ，如下所示...

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example.app"
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName '1'
    }
}

注意运行时权限始终是首选方法。

您的Android 6用户可以有选择地撤销您的应用程序的权限，因此您必须在运行时请求权限。

来自the documentation的示例：

private static final int MY_PERMISSIONS_REQUEST_FINE_LOCATION = 111;

// ...

// Check for permission
if (ContextCompat.checkSelfPermission(thisActivity,
                Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(
            this, // Activity
            new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                MY_PERMISSIONS_REQUEST_FINE_LOCATION);
    }
}

// Get permission result
@Override
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_FINE_LOCATION: {
            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted

            } else {
                // permission was denied
            }
            return;
        }
    }
}

客户端必须具有ACCESS_FINE_LOCATION权限才能在android 6中请求PRIORITY_HIGH_ACCURACY位置
