java.lang.IllegalStateException：无法从CursorWindow读取第0行col -1。确保正确初始化Cursor

Question

我正在尝试从图库中读取图片。我正在使用带有marshmallow android版本的Motorola G2设备。

方法：

public String getPath(Uri uri) {
    String[] projection = {MediaStore.Images.Media.DATA};                   

   // Cursor cursor = this.getActivity().getContentResolver().query(uri, projection, null, null, null);

    Cursor cursor = this.getActivity().managedQuery(uri, projection, null, null, null);

    int column_index = cursor.getColumnIndex(projection[0]);
    System.out.println("In Iconiq:: In postImage:: Index:: " + column_index);
    cursor.moveToFirst();

    return cursor.getString(column_index);
}
