イースター、おめでとう

そして、あなたの助けを前もってありがとうございました.

サービスを介して 1 分ごとに更新されるアプリ ウィジェットがあります。

サービスはインターネットからデータを収集するため、ウィジェットの更新に数秒かかります。

問題は、その更新時間中にアプリ ウィジェット自体が数秒間完全に別の画像に置き換えられ (下の画像を参照)、その後通常の状態に戻ることです。

ウィジェットは通常、次のように表示されます。

ここに画像の説明を入力

これは、更新中に何が起こるかです!!!

ここに画像の説明を入力

数秒後、すべてが再び正常になります。

ここに画像の説明を入力

これを回避する方法についての提案は大歓迎です!!

この投稿で誰かが行った方法で、サービスをセルフストップしようとしました: Android ウィジェットが更新中に奇妙な画像を表示する

しかし、成功しませんでした。

これは、アプリ ウィジェットを更新するサービスのコード全体です (あまり役に立たないと思います)。
