java – Android Phonegap 2.1> 2.2升级错误

我正在开发一个Phonegap应用程序,看到Phonegap最近已经更新到2.2,有很多Android修复程序.所以我立即更新了xml,jar和JS文件.我的应用曾经很棒.它使用自定义Javascript界面​​来添加其他功能.不幸的是,当升级到2.2时,我收到以下错误日志：

Pastebin error log

这是我在运行4.0.4的Samsung galaxy S2上运行应用程序时出现的错误.这是我正在使用的主要应用程序Java文件.

Pastebin Java File

我希望你们能帮助我发现问题.我对可能导致JNI错误的原因一无所知.

编辑：我在Android 2.2模拟器上尝试了相同的代码,这给了我一个更具描述性的错误：

提前致谢！

解决方法:

此问题有一个当前的解决方法,那就是您将线程池添加到CordovaActivity：

private final ExecutorService threadPool = Executors.newCachedThreadPool();

当然,实现新添加的getThreadPool()方法.这是偶然添加的,并且希望以某种方式封装在下一个版本中.

public ExecutorService getThreadPool()
{
    return threadPool;
}
