Java 启动外部意图在Cordova 1.6上有效，但在3.0 Android上无效

java javascript android

Java 启动外部意图在Cordova 1.6上有效，但在3.0 Android上无效,java,javascript,android,phonegap-plugins,cordova-3,Java,Javascript,Android,Phonegap Plugins,Cordova 3,我一直在开发一个Cordova Phonegap应用程序，可以启动外部活动。当使用Cordova 1.6时，一切正常，但当我使用Cordova 3.0时，插件将无法工作，测试时，我也不会在logcat上收到任何输出消息。请记住，cordova-1.6.jar中的某些类名与cordova-3.0.jar中的类名不同，因此在实现代码时，导入和某些方法会有一些小的更改。下面是我使用Cordova 3.0版的完整代码： java插件java类 调用插件的startapp.jsJavascript 这里是

java插件java类 调用插件的startapp.jsJavascript 这里是我定义插件的地方 plugins.xml定义插件Cordova 1.6
插件java代码被调用了吗？你能在里面放一个log语句，看看它是否被调用吗？你好，Mooreds，我在java插件类StartApp.java中添加了一个log语句，但在LogCat中没有得到任何输出。我要做的是发布Cordova 1.6的代码，它的工作方式就像一个魔咒，看看它们的区别！StartApp的原始作者：对不起，我目前没有做任何Android开发，最近安装了新的操作系统，所以我现在甚至没有安装模拟器。不管怎样，您是否碰巧在日志中看到一些JavaScript错误？cordova.exec甚至被执行了吗？可能会在cordova.exec之前/之后添加一些JS日志记录甚至警报。这个调用的返回值是多少？你好，dmedvinsky，我很高兴地说我找到了解决方案，并重新编写了插件类以适应Cordova 3.0.0 API。。我将很快在github上发布回购协议，供大家分享；你有什么最新消息吗
