android - 打包aar 时 如何不混淆某个类及里边的某个方法呢

Question

package com.demo.download下有个 DownloadManager 类

1. public static DownloadManager getInstance() 方法

2. public void startDownload(Url url, String path, Callback);

假设就以上两个方法是对外公开的，这两个方法名及类名我不想混淆，
其他的方法名称及变量名称想都混淆了

该如何写混淆文件呢？？

Answer 1

1. Use @keep’s annotation
2. Google how to configure @keep in the proguard file

Answer 2

-keep class com.demo.download.DownloadManager  {
  public static DownloadManager getInstance();
  public void startDownload(Url, java.lang.String, Callback);
}
