我的 android 应用程序在以下代码行崩溃：

Cursor cursor= getActivity().getContentResolver().query(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI,columns,
                    selection, selectionArgs, orderBy);

崩溃日志：

我怎样才能避免它？

我怀疑以下代码也可能是崩溃的原因

if (cursor!= null)
                cursor.moveToFirst();

光标始终关闭。

提前感谢任何帮助。

谢谢

试试这个技巧

Cursor cursor= getApplicationContext().getContentResolver().query(
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI,columns,
                    selection, selectionArgs, orderBy);

 if (cursor != null) {
   if (cursor.moveToFirst()) {
       ///// Put your idea here
   }
   cursor.close(); 
}
