恢复我的PhoneGap的应用程序时，当我开始我的应用程序，让它运行，后来回来它，然后点击应用程序图标，我经常得到的，“不幸的是，已经停止”。然后我再运行它，它很好。起初我认为这是因为任务杀手，但我从杀人名单中删除它，我仍然得到它。调试转储低于：“不幸的是，<myApp>已停止”在Android

我查看了CordovaWebview的代码[这里]（https://github.com/apache/cordova-android/blob/master/framework/src/org/apache/cordova/CordovaWebView.java），我不知道看不到indexOf的调用。你能告诉我你正在使用什么版本的Cordova吗？或者，甚至更好，找到这个调用的代码片段？ – verybadalloc
我的Jar文件是cordova-2.3.0.jar。 java代码非常简单，我已经将它发布在上面的原始问题中。 – user1798818
这确实是一个非常有趣的错误。在[科尔多瓦的（https://github.com/apache/cordova-android/blob/a0d2b96de6c13dc61cbe4701c8fbf10350a41845/framework/src/org/apache/cordova/CordovaWebView.java）代码一些挖后，似乎网址将成为空，虽然它已正确登录onPageFinished。你能用早期的版本来试用你的相同的代码，比如说2.4吗？ – verybadalloc
