XML フィードを解析し、そのタイトルと画像を表示するウィジェットがあります。このウィジェットでは、定期的にコンテンツ (つまり、タイトルと画像) を変更するサービスを使用しています。このために、タイマー クラスを使用しています。このウィジェットを実行すると、一部のコンテンツは問題なく表示されますが、しばらくすると強制終了し、「ウィジェット更新の RemoteViews が最大ビットマップ メモリ使用量を超えています (使用: 2465280 最大: 2304000) 合計メモリは、デバイスの画面を満たすために必要な量を超えることはできません。一度"。この問題を解決するために誰か助けてください...よろしくお願いします
これが私の AppwidgetProvider=> です
