在Oreo / Nougat中在拨出呼叫上启用扬声器时出错

问题描述 投票：3回答：1

我需要在拨出电话期间打开扬声器，但它的抛出异常下面是我使用过的代码片段：

audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
                    audioManager.setMode(AudioManager.MODE_IN_CALL);
                    if (!audioManager.isSpeakerphoneOn())
                        audioManager.setSpeakerphoneOn(true);
                    audioManager.setMode(AudioManager.MODE_NORMAL);

它适用于6.0以下的设备，但不适用于8.0和7.0。

logcat的：

找到了答案。

您正在尝试在通话期间使用AudioManager，Android系统禁止使用它。在扬声器上实现设置的方法是替换Phone行为并实现InCallService。

然后你可以打电话给setAudioRoute(CallAudioState.ROUTE_SPEAKER)，并能够处理不同的设备（如蓝牙或有线耳机）。

您可以在此处查看API定义：https://developer.android.com/reference/android/telecom/InCallService#setAudioRoute(int)
