私はデバイスに接続して仕事をしているBluetoothアプリケーションをやっています。私にはたくさんの活動があります。私はBlutoothConnectionService.java
クラスのすべての接続を行います。私の中でBondedDevicesActivity
私は接続したいデバイスをクリックします。その後、サービスが動作し、別のアクティビティが開かれます。次に、いくつかのボタンをクリックして別のアクティビティを開きます。すべての活動で、私はブルートゥースを介していくつかの情報を送信しています。したがって、別のアクティビティを開くたびに、私はBlutoothConnectionService.java
クラスを使用します。問題はこのクラスにあり、常にデバイスに接続しようとしています。私はそれが接続されたら、それが決して接続が死ぬまでそれをもう一度試してみたいです。しかし、私はそれを作る方法を理解できませんでした。私はisConnected()
と呼ばれる方法があることを知っていますが、私はそれをサービスクラスに入れる場所がわかりません。ここにサービスの私のコードは次のとおりです。Bluetooth IsConnected()
