其实你是没办法控制其他app，只是把audio这个服务抢过来。具体原理还没搞清楚。先提供代码给你们，能用最好。
public void stopOtherAppVoice(final Context context){
this.mAudioManager = (AudioManager)context.getApplicationContext().getSystemService("audio");
if (!this.isHeadphonesPlugged(this.mAudioManager)) {
this._sensorManager = (SensorManager)context.getApplicationContext().getSystemService("sensor");
if (this._sensorManager != null) {
this._sensor = this._sensorManager.getDefaultSensor(8);
this._sensorManager.registerListener(this, this._sensor, 3);
}
}
this.muteAudioFocus(this.mAudioManager, true);
}
@TargetApi(8)
private void muteAudioFocus(AudioManager audioManager, boolean bMute) {
synchronized(this.mLock) {
if (audioManager != null) {
if (bMute) {
audioManager.requestAudioFocus(this.afChangeListener, 3, 2);
} else {
audioManager.abandonAudioFocus(this.afChangeListener);
this.afChangeListener = null;
}
}
}
}
关键代码就这些，要完整代码的，私信我。
