MTK 如何设置视频来电的默认铃声

[DESCRIPTION]

背景：

原始设计语音来电铃声和视频来电铃声是一起设置的。即设置的默认铃声同时是语音来电和视频来电的铃声。

需求：

只想单独设置视频来电的默认铃声。

实现思路：

参考原先来电铃声的设置机制，给视频来电铃声单独设置属性写默认的铃声名称，然后在文件扫描时，判断扫描到的文件是设置的默认视频铃声的文件名，则在database中填写视频来电的键值为此铃声；

PS:被设置的铃声首先要存在于系统中，关于如何添加系统铃声请参考”FAQ06323[Audio
Profile]如何添加以及删减特定的默认通知铃声，如何设置默认铃声”；

[SOLUTION]

1，添加Video Call默认铃声的属性：

alps\build\target\product\core.mk中添加“ro.config.video_call”：

PRODUCT_PROPERTY_OVERRIDES := \

ro.config.notification_sound=Proxima.ogg \

ro.config.alarm_alert=Alarm_Classic.ogg \

ro.config.ringtone=Backroad.ogg \

ro.config.video_call=VideocallRt.ogg

2，添加对扫描到文件的判断是否是默认Vide Call的默认铃声：

alps\frameworks\base\media\java\android\media\mediascanner.java:

1),添加成员变量用做后面的判断：

private String mDefaultRingtoneFilename;

private String mDefaultVideocallFilename;

private boolean mDefaultRingtoneSet;

private boolean mDefaultVideoCallSet;

private static final String RINGTONE_SET = "ringtone_set";

private static final String VIDEOCALL_SET = "videocall_set";

2):添加读取video call默认铃声的系统属性：

private void setDefaultRingtoneFileNames() {

mDefaultRingtoneFilename = SystemProperties.get(DEFAULT_RINGTONE_PROPERTY_PREFIX

+ Settings.System.RINGTONE);

mDefaultVideocallFilename = SystemProperties.get(DEFAULT_RINGTONE_PROPERTY_PREFIX

+ Settings.System.VIDEO_CALL);//add this line

...

}

3):添加对扫描到的文件是否是视频来电默认铃声的判断：

参考标有//start modify”和//end modify”中间包含的为添加整段code，"//add this line"和”Modify this line"为添加添加的语句和修改的语句。

并请留意“else if (ringtones && doesSettingEmpty(RINGTONE_SET)&&!videocall) {”中要一定注释掉对VideoCall的设置：

private Uri endFile(){

boolean videocall = false; //add this line

.....

if (notifications &&((mWasEmptyPriorToScan && !mDefaultNotificationSet) ||

doesSettingEmpty(NOTIFICATION_SET))) {

....

//start modify

} else if(ringtones && ((mWasEmptyPriorToScan && (!mDefaultRingtoneSet||!mDefaultVideoCallSet)) || doesSettingEmpty(RINGTONE_SET)|| doesSettingEmpty(VIDEOCALL_SET))) {

if (TextUtils.isEmpty(mDefaultRingtoneFilename) ||

doesPathHaveFilename(entry.mPath, mDefaultRingtoneFilename)) {

needToSetSettings = true;

/// M: Adds log to debug setting ringtones.

Xlog.v(TAG, "endFile: needToSetRingtone=true.");

}

if (TextUtils.isEmpty(mDefaultVideocallFilename) ||

doesPathHaveFilename(entry.mPath, mDefaultVideocallFilename)) {

needToSetSettings = true;

videocall = true;

/// M: Adds log to debug setting ringtones.

Xlog.v(TAG, "endFile: needToSetRingtone=true.");

}

} else if (alarms && ((mWasEmptyPriorToScan && !mDefaultAlarmSet) ||

doesSettingEmpty(ALARM_SET))) {

...

}

...

if(needToSetSettings) {

if (notifications && doesSettingEmpty(NOTIFICATION_SET)) {

.....

//start modify

} else if (ringtones && (doesSettingEmpty(RINGTONE_SET)||doesSettingEmpty(VIDEOCALL_SET)) {

if(videocall){

setSettingIfNotSet(Settings.System.VIDEO_CALL, tableUri, rowId);
setProfileSettings(RingtoneManager.TYPE_VIDEO_CALL, tableUri, rowId);

mDefaultVideoCallSet = true;

setSettingFlag(VIDEOCALL_SET);

}

else{

setSettingIfNotSet(Settings.System.RINGTONE, tableUri, rowId);

// setSettingIfNotSet(Settings.System.VIDEO_CALL, tableUri, rowId); //modify this line

setSettingIfNotSet(Settings.System.SIP_CALL, tableUri, rowId);

setProfileSettings(RingtoneManager.TYPE_RINGTONE, tableUri, rowId);

// setProfileSettings(RingtoneManager.TYPE_VIDEO_CALL, tableUri, rowId);//modify this line

setProfileSettings(RingtoneManager.TYPE_SIP_CALL, tableUri, rowId);

mDefaultRingtoneSet = true;

setSettingFlag(RINGTONE_SET);

}

Xlog.v(TAG, "endFile: set ringtone. uri=" + tableUri + ", rowId=" + rowId);

//end modify

}else if (alarms && doesSettingEmpty(ALARM_SET)) {

....
