Android 在Oreo/Nougat中启用传出呼叫扬声器时出错

在拨出电话时，我需要打开扬声器，但下面抛出的异常是我使用的代码片段：

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

它在低于6.0的设备上运行良好，但在8.0和7.0中不起作用

找到了答案

您试图在通话中使用AudioManager，而Android系统禁止使用。实现扬声器设置的方法是更换手机行为并实施InCallService

然后您可以调用

setAudioRoute（CallAudioState.ROUTE\u SPEAKER）

，并能够处理不同的设备（如蓝牙或有线耳机）

您可以在这里看到API定义：

您可以同时添加错误日志吗？@kshishoo我已经添加了日志。请查看它您找到解决方案了吗？您是否同时连接了蓝牙或耳机？是否可以在TelephonyManager事件中使用setAudioRoute功能？
