如何在ARFragment中添加存储权限？

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

private static final int STORAGE_PERMISSION_REQUEST_CODE = 1;

...

// 检查是否拥有存储权限，如果没有则请求权限
private void checkStoragePermission() {
    if (ContextCompat.checkSelfPermission(getActivity(),
            Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
        requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                STORAGE_PERMISSION_REQUEST_CODE);
    } else {
        // 已拥有存储权限，进行存储相关操作
        performStorageOperation();
    }
}

// 处理权限请求结果
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == STORAGE_PERMISSION_REQUEST_CODE) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // 存储权限已授予，进行存储相关操作
            performStorageOperation();
        } else {
            // 存储权限被拒绝，可以在此处进行相应处理
        }
    }
}

// 进行存储相关操作
private void performStorageOperation() {
    // 在这里进行存储相关操作，例如读写文件等
}

@Override
public void onResume() {
    super.onResume();
    checkStoragePermission();
}
