MainActivityZephyr クラスに測定値を送信する Zephyr HxM デバイスがあります。測定値は正しく受信され、logcat に出力されます。測定値が受信されると、メソッド測定で分析され、editText は受信したすべての測定値で継続的に変化し続けるはずです。
アクティビティが HxM デバイスに接続するとすぐに、アクティビティは完全にフリーズし、editText は変更されませんが、受信した値はログ cat に正常に出力され、コードは正常に実行され、条件が満たされると、ユーザーはRedAlert アクティビティに正常に転送されます。
なぜこれが起こっているのか、どうすれば修正できるのかについての助けをいただければ幸いです! 前もって感謝します。
