android - SecurityException: Permission Denial 即使我正在获取运行时权限

问题描述

我在使用 Android 7.0 的多台设备的 Crashlytics 上遇到异常情况-

Caused by java.lang.SecurityException: Permission Denial: reading com.android.providers.media.MediaProvider uri content://media/external/video/media from pid=7070, uid=12033 requires android.permission.READ_EXTERNAL_STORAGE, or grantUriPermission()

我研究并发现当我们在 Android 6.0+ 设备中不采取运行时异常时会发生此异常。但是在我的项目中，我在任何需要的地方都使用了运行时权限。崩溃没有指定我项目的任何特定行。下面的代码我用来从用户那里获取运行时权限 -

  uploadVideo.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if (Build.VERSION.SDK_INT >= 23)
                        getPermission();
                    else
                        uploadVideo();

                }
            });


private void getPermission() {
        String[] params = null;
        String writeExternalStorage = Manifest.permission.WRITE_EXTERNAL_STORAGE;
        String readExternalStorage = Manifest.permission.READ_EXTERNAL_STORAGE;

        int hasWriteExternalStoragePermission = ActivityCompat.checkSelfPermission(this, writeExternalStorage);
        int hasReadExternalStoragePermission = ActivityCompat.checkSelfPermission(this, readExternalStorage);
        List<String> permissions = new ArrayList<String>();

        if (hasWriteExternalStoragePermission != PackageManager.PERMISSION_GRANTED)
            permissions.add(writeExternalStorage);
        if (hasReadExternalStoragePermission != PackageManager.PERMISSION_GRANTED)
            permissions.add(readExternalStorage);

        if (!permissions.isEmpty()) {
            params = permissions.toArray(new String[permissions.size()]);
        }
        if (params != null && params.length > 0) {
            ActivityCompat.requestPermissions(MainActivity.this,
                    params,
                    100);
        } else
            uploadVideo();
    }

 @Override
    public void onRequestPermissionsResult(int requestCode,
                                           String permissions[], int[] grantResults) {
        switch (requestCode) {
            case 100: {

                if (grantResults.length > 0
                        && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    uploadVideo();
                }
            }
  }
}

更新

根据阿里的回答，我需要分别检查这两个权限是否被授予。但是按照这个，如果授予了权限组中的任何权限，同一组中的另一个权限也会被自动授予。并且读写外部存储权限属于同一组。
