AudioManager's isSpeakerPhoneOn is flooding the logs.

It is coming via

protected class CommDeviceSniffer extends NativeSniffer {
    @Override
    public void updateStatusText() {
       showCommDeviceStatus();
    }
}

triggered from here
public void run() {
if (!isComplete()) {
updateStatusText();
}

    // When this is no longer enabled, stop calling run.
    if (mEnabled) {
        mHandler.postDelayed(this, SNIFFER_UPDATE_PERIOD_MSEC);
    }
}

->probably isComplete is not overriden in CommunicationDeviceView to mark sniffing complete.

Can you please check ?

Robert, could you please take a look? Thanks,

Every time the sniffer runs, we update the UI. However, we don't add anything to the logs. mSpeakerStatusView.setText() doesn't log anything to logcat. I don't see logs on my phone. Can you double check and add the logs that you see? Thanks!

    private void showCommDeviceStatus() {
        boolean enabled = mAudioManager.isSpeakerphoneOn();
        String text = ":" + (enabled ? "ON" : "OFF");
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) {
            AudioDeviceInfo commDeviceInfo = mAudioManager.getCommunicationDevice();
            if (commDeviceInfo != null) {
                text += ", #" + commDeviceInfo.getId();
            }
        }
        mSpeakerStatusView.setText(text + ",");

        if (mScoState == AudioManager.SCO_AUDIO_STATE_CONNECTING) {
            text = ":WAIT";
        } else if (mScoState == AudioManager.SCO_AUDIO_STATE_CONNECTED) {
            text = ":CON";
        } else if (mScoState == AudioManager.SCO_AUDIO_STATE_DISCONNECTED) {
            text = ":DISCON";
        }
        mScoStatusView.setText(text);
    }

private void showCommDeviceStatus() {
    boolean enabled = mAudioManager.isSpeakerphoneOn(); --->>>>> This line is frequently logging which comes from AudioManager.

From the AOSP source code, it looks like there is not such a log. Is this from customized log? But I think given the API is deprecated, it is better for oboe to call new API according to the guidance.

Yes, seems it is our custom log, but it catches the problem to frequently call AudioManager API.
Even if we plan to use new API, that should not too frequently call AudioManager.

That is good point. To show the communication device correctly, it is better to call it once and register a callback for the update instead of frequently calling the AudioManager API.
