Android 2.3中Webkit引擎导致VM崩溃的问题

gloomyboyo 2011-05-10

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。
