Android 2.3中Webkit引擎导致VM崩溃的问题
Android2.2,2.3,2.3.3都存在的一个bug,在这里 http://www.linuxidc.net/thread-2203-1-1.html有详细的描述。
其中，楼主的代码可以下来运行一下，我在2.2和2.3模拟器和2.3的真机上都存在这个问题。
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。
对这个问题进行跟踪时，费了很大的劲，所以先记录一下跟踪过程。
