Question

我尝试在通话模式下将设备音频设置为扬声器它在我检查的大多数设备上工作。

我购买了OnePlus5设备并且没有使用它。

final AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.stopBluetoothSco();
audioManager.setBluetoothScoOn(false);
audioManager.setSpeakerphoneOn(true);

当我检查结果是假的时候：

audioManager.isSpeakerphoneOn() // return false

正如我在logcat中看到的那样，当我从原生拨号器设置扬声器时，他们使用一些不同的对象来设置扬声器：
