有时一个大项目下面会有很多个小模块，如果小模块之间没有联系，这时可以将每个小模块作为单独的项目，生成apk。
这时就涉及到怎么将多个apk放到一个项目中。
首先，将小模块生成的apk放到项目的assets文件夹中
java代码：

// 监听系统新安装程序的广播

filter.addDataScheme("package"); // 必须添加这项，否则拦截不到广播
registerReceiver(receiver, filter);
baoxian_zhushou = (ImageView) findViewById(R.id.baoxian_zhushou);
// 主页面小模块的图标
baoxian_zhushou.setOnClickListener(new OnClickListener() {
