setRingerMode到来电时normall在三星设备不工作 [英] setRingerMode to normall during incoming call doesn't work on Samsung devices

问题描述

我读过这里。没有找到答案。

I've read here. Didn't find the answer.

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，上述code取消静音和调节音量到最大。
这code适用于Nexus设备（如Galaxy Nexus的）
但是，它不会对三星设备（S3，S4，注2）的Andr​​oid 4.3版]工作。

When the device is on silent mode or vibration mode, above code unmute and change the volume to the max. This code works on Nexus devices (eg. Galaxy Nexus) However, it doesn't work on Samsung devices (S3, S4, Note 2) [Android version 4.3].

有什么建议？

推荐答案

因为我找不到答案，我通过实际播放振铃声音在我的服务想出了解决方法。

Since I couldn't find the answer, I came up with the work-around by actually playing the ringer sound in my service.
