请更详细地描述这个问题，并可能发布完整的stacktracecontent://com.google.android.apps.photos.contentprovider/-1/2/content%3A%2F%2Fmedia%2Fexternal%2Fvideo%2Fmedia%2F727/ORIGINAL/NONE/113623020 这是库中选定视频的uri。在游标Cursor=getActivity（）.managedQuery（uri，null，null，null，null）上获取崩溃；请更新上面的问题描述，添加用于获取视频的代码和用于处理问题的代码response@Vaibhavi是否可能复制/粘贴了错误的堆栈跟踪？我没有看到关于无效列的任何内容。我也面临同样的问题。在此处检查我的解决方案：

 Intent intent = new Intent();
            intent.setTypeAndNormalize("video/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            intent.addCategory(Intent.CATEGORY_OPENABLE);
            startActivityForResult(Intent.createChooser(intent, "Select Video"),  GALLERY);
