Android 8.1 铃声音量通话音量同步调节

最近收到客户反馈，想要实现铃声音量通话音量同步调节，具体修改参照如下：

/frameworks/base/core/java/android/preference/SeekBarVolumizer.java

        if (defaultUri == null) {if (mStreamType == AudioManager.STREAM_RING) {defaultUri = Settings.System.DEFAULT_RINGTONE_URI;} else if (mStreamType == AudioManager.STREAM_NOTIFICATION) {defaultUri = Settings.System.DEFAULT_NOTIFICATION_URI;//*/tyd.zcb, 20240116. voice call set null} else if (mStreamType == AudioManager.STREAM_ALARM) {defaultUri = Settings.System.DEFAULT_ALARM_ALERT_URI;} else {defaultUri = null;}/*/} else {defaultUri = Settings.System.DEFAULT_ALARM_ALERT_URI;}//*/

/vendor/mediatek/proprietary/packages/apps/MtkSettings/src/com/android/settings/notification/SoundSettings.java

        public void onStreamValueChanged(int stream, int progress) {
+            if (stream == AudioManager.STREAM_VOICE_CALL) {
+                AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
+                audioManager.setStreamVolume(stream, progress, 0);
+            }}

重新编译验证，修改生效，铃声音量通话音量已实现同步调节
