关于dynamic-load插件式开发

标签：插件开发

dynamic-load插件式开发可以访问没有安装的APK中的类，也就是APK无需安装就可以被打开。具体原理有相关文档参考  http://blog.csdn.net/singwhatiwanna/article/details/22597587

       其中有一些缺陷，插件中无法调用系统相册或者相机等，只要是用到intent调用系统acitivity都是行不通的。

     dynamic-load有三种开发模式，第一种是主程序与插件没有交互完全独立开发的，第二种是插件可以调用主程序提供的接口（因为插件中不支持.so，service等，需要在主程序中注册，再提供接口给插件中使用），第三种没有去研究，文档中不推荐，也就没怎么看。具体可以看文档介绍。

        接下来看demo   demo用的是第一种开发模式  demo下载地址

        用法  ，demo中的Camera、ScaleAnimationDemo2、uploadTemp为插件，update为主程序。首先将   Camera.apk，ScaleAnimationDemo2.apk，uploadTemp.apk放入手机SDK 中的DynamicLoadHost文件中，如没有就在内置SDK中创建DynamicLoadHost文件，DynamicLoadHost文件名可以随便改的，必须和主程序中的

String apkPaths=Environment.getExternalStorageDirectory()+"/DynamicLoadHost";

         如果想在手机上运行安装后的插件，将插件中的plugslibs名字换成libs，就可以安装并正常运行，否则会报错。

         在dynamic-load开发中，主程序，插件都要用到dl-lib.jar包，主程序dl-lib只需放在libs中，插件中必须将libs改名，将dl-lib放在改名中的libs中，demo中改名为pulgslibs，并且右键build path——configure buid path——Libraries中点击Add Jars找到自己插件中的pulgslibs里的dl-lib确定，运行出来的apk就可以放在SDK中的DynamicLoadHost文件下，通过主程序运行就可以了。
