android - GridLayoutの膨張例外

Question

非常に単純なウィジェットを使用してウィジェットを作成したいのですGridLayoutが、InflateExceptionが発生しました。

Binary XML file line #2: Error inflating class android.widget.GridLayout

4.0でのみ発生し、4.2では問題なく動作します（バージョン間に違いはありますか？）誰かがそれについて何か知っていますか？

RemoteViewでは、一部のレイアウトのみをコンテンツ内で膨張させることができます。ここでリストを確認できます

たとえば、TableViewが許可されていないことがわかります。logcat メッセージは、GridViewが許可されていないことを示していますが、ドキュメントでは許可されています。この機能はかなり新しいもので、4.2 より前のバージョンでは許可されていなかったと思います。または4.1。

おそらく、リモートビューで別のレイアウトタイプを使用する必要があります。
