Question

我看过here。没有找到答案。

public class CallReceiver extends BroadcastReceiver {

private TelephonyManager mTelephony;
private IncomingPhoneStateListener mIncomingPhoneListener;
private String number;
private Context mContext;

@Override
public void onReceive(Context context, Intent intent) {
    try {
        mContext = context;
        number = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
        mTelephony = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        mIncomingPhoneListener = new IncomingPhoneStateListener();
        mTelephony.listen(mIncomingPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);
    } catch (Exception e) {
        Log.e("CallReceiver", "onReceive error:" + e.getMessage());
    }
}

public class IncomingPhoneStateListener extends PhoneStateListener {
    @Override
    public void onCallStateChanged(int state, String incomingNumber) {

        AudioManager am = (AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE);

        switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:

                // ******* This code should unmute and change volume to MAX
                am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
                am.setStreamVolume(AudioManager.STREAM_RING, am.getStreamMaxVolume(AudioManager.STREAM_RING), AudioManager.FLAG_PLAY_SOUND);
                // ******* end
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                break;
            default:
                break;
        }
        super.onCallStateChanged(state, incomingNumber);
        mTelephony.listen(mIncomingPhoneListener, PhoneStateListener.LISTEN_NONE); // unregister
    }
}

}

当设备处于静音模式或振动模式时，上面的代码取消静音并将音量更改为最大值。此代码适用于Nexus设备（例如Galaxy Nexus）但是，它不适用于三星设备（S3，S4，注2）[Android版本4.3]。

有什么建议吗？

由于我找不到答案，所以在我的服务中实际播放铃声，我想出了解决方法。

来电期间setRingerMode正常，不适用于三星设备
