Python用sl4a开发Android应用，Webview中javascript调用android api闪退
如题
Python版本2.6.2
sl4a版本r6
主程序在webview中打开页面
# -*- coding: cp936 -*-
import android,sys
import time
if __name__ == '__main__' :
droid = android.Android()
droid.addOptionsMenuItem('Exit','exit')
droid.webViewShow('file:///sdcard/sl4a/scripts/home.html')
while True:
response = droid.eventWait().result
if response == None:
continue
print response
if response['name'] == 'exit':
break然后在页面中定义方法调用android apisayHello = function(){
var droid = new Android();
droid.makeToast('HelloWorld')
}然后调用sayHello方法，程序就闪退了
网上搜了很久找不到原因，求指点啊～～

貌似我找到问题所在了，据说是Android2.3中的bug引起的
Android 2.3中Webkit引擎导致VM崩溃的问题
http://www.linuxidc.com/Linux/2011-05/35782.htm
不过那个作者写的解决方法太高端，没看懂，求简易解决方法～～～～
补充，安卓api版本是2.3.3
