推荐答案

如果将设备连接到蓝牙，音频通过设备播放将通过蓝牙流唯一正确的？

If the device is connected to a bluetooth, audio played through the device will be streamed through bluetooth only right?

因此​​，也许你可以先检查设备是否连接到蓝牙设备搭配：

So maybe you can first check whether the device is connected to a bluetooth device with :

AudioManager audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
if(audioManager.isBluetoothA2dpOn()) {
    // Play audio...
}

Android的 AudioManager 类有更多的细节你可以钻进去。

Android's AudioManager class has more details what you can dig into.

如果蓝牙未连接，您可以以编程方式检查并连接到使用蓝牙机器人的包。

If the bluetooth is not connected you can programmatically check and connect to available bluetooth devices using Androids bluetooth package.
