No persistable permission grants found for URI

问题

I'm using the intent action ACTION_GET_CONTENT.

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

I need to use the URI in onActivityResult for copying the image that a user chooses and compress the copied image.

But I'm getting this error even after taking uri permission using takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION) in onActivityResult. This works well when I use the Intent action ACTION_OPEN_DOCUMENT.

Here is the stack trace:

takePersistableUriPermission() is for ACTION_OPEN_DOCUMENT and other actions that are part of the Storage Access Framework, not for ACTION_GET_CONTENT.

回答2:

Have you declared the permissions in your manifest file ?

Please try to add these two permissions.

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

Hope it helps.
