apkを使用して直接インストールするとアプリケーションが動作しますが、プレイストアにアップロードされたapkは機能しません。apkを使用して直接インストールするとアプリケーションが動作しますが、プレイストアにアップロードされた同じapkは動作しません。
バックグラウンドで実行されているインテントサービスを除いて、すべての機能が動作しています。サービスはある時間間隔の後に破壊されています。
私はフォアグラウンドサービスを使用しようとしましたが、dint作業を使用しました。

サービスが破棄されたときにリスナーを追加してから、リスナーを再起動して確認してください。 –
インテントサービスの代わりにサービスを使用する方が良いでしょう。インテントサービスは一度処理を終えた後に自分自身を破棄します。 – Reena
フローをトレースするためにいくつかのコメントを追加しました。サービスは実行中ですがデータはアップロードされません私はアプリからアプリをクリアして再起動すると、アプリを開いた直後にすべてのデータがアップロードされます。 –
