在库包中进行了一些潜水之后，我编写了一条规则来保护android.support.**上的所有内容，现在我终于只保护了android.support. .v7.widget.RoundRectDrawable.

After some diving in the library packages, I wrote a rule that protected everything at android.support.** and now I'm finally protecting just android.support.v7.widget.RoundRectDrawable.

因此，如果您对此有疑问，只需在您的proguard配置中添加下一条规则即可:

So if you are having troubles with this, just add the next rule at your proguard config:

-keep class android.support.v7.widget.RoundRectDrawable { *; }
