¿Cómo verificar si hay auriculares bluetooth conectados a Android en este momento?¿Cómo verificar si los auriculares bluetooth están conectados en Android?

igual:

  • Si hay un auricular conected, la ruta debe sonar a este auricular

  • Pero si no hay una auriculares, el sonido debe permanecer en el altavoz

  • Esto debe verificar durante la aplicación, ya que si la batería del auricular se apaga, debe enviar sonido a la parte posterior del altavoz

Acabo de limpiar el código y lo generalicé un poco para que otros usuarios tengan el mismo problema. No publique elementos no relacionados como "android.bluetooth.headset.action.FORCE_ON" o "android.bluetooth.headset.action.FORCE_OFF" (que se refieren a las acciones creadas por usted mismo). Además, no use comentarios en idiomas extranjeros, por favor. :) Por cierto, gracias por el código. :) – DragonWork
