今天的教程简单演示一下如何给一款apk加启动弹窗 对话框等。
演示apk：华硕手机计算器4.0.0.52
工具：MT或者电脑端反编译工具
操作步骤：
首先正常安装打开这款软件是这样的。工具打开很简洁，没有任何权限提示
按常规操作。首先找到这个apk，使用MT的ACTIVITY记录，点击开启。我们要先查看这个工具启动的主界面Activity 的代码名字。
然后打开这个计算器工具，在上方的Activity就可以看到工具主界面
点击查看，选择classes.dex文件。关于apk资源内各个文件夹的具体作用可以查看以前的博文都有说明。点击classes.dex文件。出来菜单选择Dex编辑器++
现在我们需要工具刚才查看到计算器的Activity记录来找到这个完整路径文件
完整的路径com.asus.calculator.Calc

我们需要定位到工具主界面Activity。加入弹窗内容
内容可以任意修改。原路返回保存可以直接签名或者编译后在签名都可以。此时卸载原软件，安装编译签名后的软件，打开是这样的
效果：
这些步骤都是反编译apk起始的初步常识操作。当然也可以添加对话框等等。类似
或者点击对话框后跳转设定的网页 类似
做这个教程的目的是让初学者了解最简单的反编译操作，尽量每一步都详细说明。其实很多工具都有些类似的功能。例如查看活动Activity记录。很多软件Activity有很多。主界面 辅界面等等。当然加启动弹窗的方式有很多种。其中的一种方法不一定都可以通用所有apk。但要明白原理.
**系列教程将详细的由浅入深解析apk的各种反编译操作。有兴趣的友友可以关注
