找不到 URI 的持久权限授予

Question

我正在使用意图操作 ACTION_GET_CONTENT。

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(i, 3);

我需要使用 onActivityResult 中的 URI 来复制用户选择的图像并压缩复制的图像。

但即使在 onActivityResult 中使用 takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION) 获得 uri 权限后，我仍收到此错误。这在我使用 Intent 操作 ACTION_OPEN_DOCUMENT.

时效果很好

这是堆栈跟踪：

Answer 1

您是否在清单文件中声明了权限？

请尝试添加这两个权限。

 <uses-permission android:name="android.permission.READ_USER_DICTIONARY">
 <uses-permission android:name="android.permission.WRITE_USER_DICTIONARY">

希望对您有所帮助。

Answer 2

But I'm getting this error even after taking uri permission using takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION) in onActivityResult.

takePersistableUriPermission() 适用于 ACTION_OPEN_DOCUMENT 和属于存储访问框架的其他操作，不适用于 ACTION_GET_CONTENT。

No persistable permission grants found for URI
