Audiomanager扬声器不起作用 [英] Audiomanager Speaker not working

问题描述

我正在尝试在通话中启用扬声器:

I'm trying to enable the speaker while I am in a call:

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

我试图在setSpeakerphoneOn()之后检查音频管理器，并通过询问isSpeakerphoneOn()

I tried to check after the setSpeakerphoneOn() the audiomanager and get that the speaker is still not on by asking isSpeakerphoneOn()

audioManager.isSpeakerphoneOn();

在我的日志中，我看到一些我不理解的错误:

In my log I can see some errors that I can't understand:

E/AudioManager: Don't setBluetoothScoOn-PackageName: com.myapp.app  on = false
E/AudioManager: Don't setSpeakerphoneOn-PackageName: com.myapp.app  on = true

我在论坛中找不到有关此错误的任何信息.

I can't find anything about this error in the forum.

无法在设备上运行:中兴Z981，华为p9，我已经尝试过此 ，并授予android.permission.MODIFY_AUDIO_SETTINGS.

Didn't work on devices: ZTE Z981, Huawei p9, I already tried this, and android.permission.MODIFY_AUDIO_SETTINGS is granted.

推荐答案

我发现setSpeakerphoneOn()之前的setMode()(当前模式)修复了logcat上的错误:

I found that setMode() (the current mode) before setSpeakerphoneOn() fixes the error on the logcat:

AudioManager audioManager = (AudioManager)getApplicationContext().getSystemService(Context.AUDIO_SERVICE); 
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setSpeakerphoneOn(true);
