是什么导致使用 AdWhirlLayout 的 rotateThreadedDelayed 出现 NullPointerException？

这是堆栈跟踪：

java.lang.NullPointerException
at com.adwhirl.AdWhirlLayout.rotateThreadedDelayed(wHAT .java:237)
at com.adwhirl.AdWhirlLayout.handleAd(AdWhirlLayout.java:210)
at com.adwhirl.AdWhirlLayout.access$3(AdWhirlLayout.java:205)
at com.adwhirl.AdWhirlLayout$HandleAdRunnable.run(AdWhirlLayout.java:390)
at android.os.Handler.handleCallback(Handler.java:587)
at android.os.Handler.dispatchMessage(Handler.java:92)

我有同样的问题很长一段时间了。目前似乎没有解决办法，只能下载 Adwhirl SDK for Android 的源代码并自行修复此 NPE。
修复本身非常简单，已在此处进行了讨论：http://groups.google。 com/group/adwhirl-users/msg/b9641da44fa0f0ce

这是固定代码：

public void rotateThreadedDelayed() {
    int cycleTime = 30; 
    if( extra != null ) { 
        cycleTime = extra.cycleTime; 
    } 
    Log.d(AdWhirlUtil.ADWHIRL, "Will call rotateAd() in " + cycleTime + " seconds"); 
    scheduler.schedule(new RotateAdRunnable(this), cycleTime, TimeUnit.SECONDS); 
}

I have same problem for quite long time. It seems like there is not solution for now, except download source code of Adwhirl SDK for Android and fix this NPE by yourself.
The fix itself is pretty straightforward and already discussed here: http://groups.google.com/group/adwhirl-users/msg/b9641da44fa0f0ce

Here is fixed code:

public void rotateThreadedDelayed() {
    int cycleTime = 30; 
    if( extra != null ) { 
        cycleTime = extra.cycleTime; 
    } 
    Log.d(AdWhirlUtil.ADWHIRL, "Will call rotateAd() in " + cycleTime + " seconds"); 
    scheduler.schedule(new RotateAdRunnable(this), cycleTime, TimeUnit.SECONDS); 
}
