没有为URI找到可持久的权限授予

时间:2016-01-07 20:51:23

标签: android android-intent permissions uri

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。

但即使在使用onActivityResult中的takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION)获取uri权限后,我也收到此错误。当我使用Intent动作ACTION_OPEN_DOCUMENT时,这很有效。

这是堆栈跟踪:

takePersistableUriPermission()适用于ACTION_OPEN_DOCUMENT以及属于Storage Access Framework的其他操作,不适用于ACTION_GET_CONTENT

您是否在清单文件中声明了权限?

请尝试添加这两项权限。

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