android - Java 语言 RuntimeException : Failure delivering result on Activity

Question

如您所见，这是我的代码，我构建了几个应用程序，在这些应用程序中我使用了几种权限方法，没有任何问题。在这种情况下，我只有一个 Activity ，但它在想要返回请求权限结果时给我一个错误。

代码:

public class ActivityStartUp extends AppCompatActivity implements ActivityCompat.OnRequestPermissionsResultCallback {
    private static final String[] PERMISSIONS = { "android.permission.CAMERA",
            "android.hardware.camera", "android.hardware.camera.autofocus",
            "android.hardware.camera.flash",
            "android.permission.ACCESS_COARSE_LOCATION",
            "android.permission.WRITE_EXTERNAL_STORAGE",
            "android.permission.READ_EXTERNAL_STORAGE" ,
            "android.permission.READ_PHONE_STATE"};

    private static final int PERMISSION_CODE = 0xBAB0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_startup);

        if (Utilities.hasMarshmallowApi()) {
            requestPermissions(PERMISSIONS, PERMISSION_CODE);
        }else{
            //Open an activity
        }

    }

    @Override
    public void onRequestPermissionsResult(int requestCode,
                                           String permissions[], int[] grantResults) {
        switch (requestCode) {
            case PERMISSION_CODE: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    G.permissionGrantStatus = true;
                    Log.i("Log", "Permission Status:" + true);
                    if(Utilities.hasMarshmallowApi()){
                        // Do something
                    }
                    // Do task
                } else {
                    G.permissionGrantStatus = false;
                    Log.i("Log", "Permission Status:" + false);
                    // permission denied, boo! Disable the
                    // functionality that depends on this permission.
                }
                return;
            }
        }
    }
}

错误:

java.lang.RuntimeException: Failure delivering result 
ResultInfo{who=@android:requestPermissions:, request=47792, result=-1, 
data=Intent { act=android.content.pm.action.REQUEST_PERMISSIONS (has extras) }} 
to activity {com.bvapp.sh.uni.watermanagement/com.bvapp.sh.uni.watermanagement.ActivityStartUp}: 
java.lang.ArrayIndexOutOfBoundsException: length=0; index=0

如您所见，错误“grantResults”的长度为 0。我试图找到一个好的解决方案，但不幸的是我找不到合适的解决方案。为什么会这样，我应该如何解决？提前致谢。

也许这是你的问题(来自:OnRequestPermissionsResultCallback() - Android Developer)

Note: It is possible that the permissions request interaction with the user is interrupted. In this case you will receive empty permissions and results arrays which should be treated as a cancellation.
