我目前正在尝试使用cordova(phonegap)进入移动设备的跨平台开发.

现在,我正在尝试构建cordova.jar-所以我刚开始.

当我运行android update project -p时. -t android-15在我的框架目录中,我得到输出：

E:\eclipse\cordova-android-master\framework>android update project -p . -t android-15
Updated project.properties
Updated local.properties
build.xml: Found version-tag: custom. File will not be updated.
Updated file E:\eclipse\cordova-android-master\framework\proguard-project.txt
It seems that there are sub-projects. If you want to update them
please use the --subprojects parameter.

然后,在我在框架目录中运行命令ant jar的步骤中,得到输出：

Buildfile: E:\eclipse\cordova-android-master\framework\build.xml

有谁知道我在做什么错？

正如自述文件所述,common-codec-1.6.jar位于lib文件夹中.

已安装android api 15级.

解决方法:

您需要使用API​​级别16进行构建,以免出现编译错误. API级别16中引入了WebSettings.setAllowUniversalAccessFromFileURLs()方法.
