问题 I've been updating meta data in the MediaStore through a ContentResolver, but this no longer works with Android Q (API 29). The following code gives me a warning, and the description is not updated: ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.DESCRIPTION, "Some text"); int res = getContext().getContentResolver().update( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values, MediaStore.Images.Media._ID + "= ?", new String[]{sImageId}); android.process.media W

I don't really get it, since MediaColumns.IS_PENDING is just a flag, how am I supposed to use it? Should I use ContentValues ? 回答1: SOLVED The code suggested from @CommonsWare has no problem, except the fact that if

问题 Background After migrating to Android Q I can no longer find a suitable way to gain write access to the documents folder ( /storage/emulated/0/Documents ) And before anyone mentions the many other questions on scoped storage I've read through many of them and from what I've seen so far all of the solutions use a app specific directory or accessing a media directory only (not documents folder access).
