在网上查了一下，好像解决办法挺麻烦的，网上的资料都说是2.3的Bug。
Android2.2,2.3,2.3.3都存在的一个bug,在这里有详细的描述。
http://code.google.com/p/android/issues/detail?id=12987
问题的核心在于这样一句话：JNI WARNING: jarray 0x4074f6e0 points to non-array object (Ljava/lang/String;)
也就是进行JNI调用时，把一个Java中的String对象当数组来访问了，最终导致虚拟机崩溃。

在网上查了下，基本算是一个比较严重的BUG，没办法解决，所以如果说用WebView组件想在js和java之间相互调用的话就没办法适应所有机型，所以做android原生应用程序时最好不要用WebView组件，否则2.3系统会直接崩溃掉。
