关于android动态权限管理

Question

最近在做定位，有一种情况是系统设置里面的应用管理权限已经打开，但是第三方的安全中心里面应用的定位权限是关闭的，这时候checkSelfPermission依然是没有授权的，无法定位，前往系统设置也不顶用，用户也不见得知道手动去打开。该怎么处理？

将动态请求权限的代码封装成一个函数，在每一次应用启动的时候调用一次，我的代码如下：

    private static final String[] PERMISSION_EXTERNAL_STORAGE = new String[]{
            Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE};
    private static final int REQUEST_EXTERNAL_STORAGE = 100;



    public void verifyStoragePermissions(Activity activity) {

        int permissionWrite = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
        int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_PHONE_STATE);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    Manifest.permission.READ_PHONE_STATE,
                    Manifest.permission.SYSTEM_ALERT_WINDOW,
                    Manifest.permission.ACCESS_FINE_LOCATION,
                    Manifest.permission.ACCESS_COARSE_LOCATION}, 5);
        }

        if (permissionWrite != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(activity, PERMISSION_EXTERNAL_STORAGE, REQUEST_EXTERNAL_STORAGE);
        }

//       if (permissionCheck != PackageManager.PERMISSION_GRANTED) {
//            ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_PHONE_STATE}, 1);
//        }
    }
