API23上的Android Google Maps API安全异常 [英] Android Google Maps API Security Exception on API23

问题描述

这是我遇到的例外:

java.lang.SecurityException
:com.google.android.gms.DynamiteModulesB line 50297 in az.c()
my location requires permission ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION


az : android.support.transition.TransitionIcs
c() : android.support.transition.TransitionIcs$CompatListener mCompatListener

我有一个使用getMap方法的地图片段，如果设备中启用了位置功能，则显示用户的当前位置，但是有时它给了我上述异常，我在代码中添加了一些位置权限检查，但是我没有不知道我错过了什么...

i have a map fragment using getMap method and show the current location of user if location is enabled in device, but sometimes it gives me the above exception, i've added some location permission check in my code, but i don't know what i've missed...

感谢帮助

这是一些其他数据:

compileSdkVersion 25
minSdkVersion 15
targetSdkVersion 25

    @Override
public void onMapReady(final GoogleMap map) {
    map.setMyLocationEnabled(true);
}

推荐答案

将这些添加到AndroidManifest.xml标记之前的AndroidManifest.xml

Add these to your AndroidManifest.xml before application tag

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

对于Android版本> = 23，还需要在运行时请求位置权限

Also for Android version >= 23, you need to request location permissions in run-time

     if (ContextCompat.checkSelfPermission(YourActivity.this,
                            Manifest.permission.ACCESS_FINE_LOCATION)
                            != PackageManager.PERMISSION_GRANTED
                            &&
                            ContextCompat.checkSelfPermission(YourActivity.this,
                                    Manifest.permission.ACCESS_COARSE_LOCATION)
                                    != PackageManager.PERMISSION_GRANTED) {
                        askForLocationPermissions();
      } else {
          //do your work
     }

和

private void askForLocationPermissions() {

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

            new android.support.v7.app.AlertDialog.Builder(this)
                    .setTitle("Location permessions needed")
                    .setMessage("you need to allow this permission!")
                    .setPositiveButton("Sure", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            ActivityCompat.requestPermissions(YourActivity.this,
                                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                                    LOCATION_PERMISSION_REQUEST_CODE);
                        }
                    })
                    .setNegativeButton("Not now", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
//                                        //Do nothing
                        }
                    })
                    .show();

            // 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.
            ActivityCompat.requestPermissions(this,
                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                    LOCATION_PERMISSION_REQUEST_CODE);

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

也

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String permissions[], @NonNull int[] grantResults) {
        switch (requestCode) {
            case LOCATION_PERMISSION_REQUEST_CODE:
                if (isPermissionGranted(permissions, grantResults, Manifest.permission.ACCESS_FINE_LOCATION)) {
                    //Do you work
                } else {
                    Toast.makeText(this, "Can not proceed! i need permission" , Toast.LENGTH_SHORT).show();
                }
                break;
        }
    }

和

   public static boolean isPermissionGranted(@NonNull String[] grantPermissions, @NonNull int[] grantResults,
                                              @NonNull String permission) {
        for (int i = 0; i < grantPermissions.length; i++) {
            if (permission.equals(grantPermissions[i])) {
                return grantResults[i] == PackageManager.PERMISSION_GRANTED;
            }
        }
        return false;
    }
