关于 Notification 的 TransactionTooLargeException的问题

最近做计步器，需要每隔五秒更新通知栏的ui,

考虑的性能问题，notification不是每次都new

然后再后台发现报了如下问题：

android.os.TransactionTooLargeException: data parcel size 521616 bytes

查看

setOnClickPendingIntent 的源码，发现
最终，系统是这么做的

 *
 * @param a The action to add
 */
private void addAction(Action a) {
    if (hasLandscapeAndPortraitLayouts()) {
        throw new RuntimeException("RemoteViews specifying separate landscape and portrait" +
                " layouts cannot be modified. Instead, fully configure the landscape and" +
                " portrait layouts individually before constructing the combined layout.");
    }
    if (mActions == null) {
        mActions = new ArrayList<Action>();
    }
    mActions.add(a);

    // update the memory usage stats
    a.updateMemoryUsageEstimate(mMemoryUsageCounter);
}

mActions 没有考虑到add的内容是否重复。。。

所以，如果重复
setOnClickPendingIntent 的话，就会产生上面的bug,

解决方案
===================》notification 复用了一百次（）之后，选择丢弃，重新new 一个，

while (flag) {
    index++;
    if (index%100==0){
    //当到第一百次的时候重新init一个，之前的丢弃
        initNotification();
    }
    else {
        addNotificaiton();
    }
}

bug解决！
