java - 更新Android Mediastore中的专辑封面？

我想将我的图像设置为音频mp3文件的专辑封面。我知道专辑ID，当我更新时，应用程序抛出java.lang.UnsupportedOperationException。

这是我的更新代码。

ContentValues values_art=new ContentValues();

values_art.put(MediaStore.Audio.AlbumColumns.ALBUM_ART, img_path);

int b=getContentResolver().update(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, values_art,MediaStore.Audio.Albums.ALBUM_ID + "=?", new String[]{album_id});

if(b !=0){
    Toast.makeText(getApplicationContext(), "Successfuly Image Updated", Toast.LENGTH_LONG).show();
}
else{
    Toast.makeText(getApplicationContext(), "Not Image Updated", Toast.LENGTH_LONG).show();
}

我的Logcat：

最佳答案

您必须先删除先前的图稿（如果已经存在）：

Uri sArtworkUri = Uri.parse("content://media/external/audio/albumart");
int deleted = getContentResolver().delete(ContentUris.withAppendedId(sArtworkUri, album_id), null, null);

然后再次插入：

ContentValues values = new ContentValues();
values.put("album_id", album_id);
values.put("_data", file_url);
Uri num_updates = getContentResolver().insert(sArtworkUri, values);
