适用于图书馆的Android-proguard项目

Question

我在我的应用程序中使用了com.tonicartos.widget.stickygridheaders.StickyGridHeadersGridView ... 这是我的proguard-project.txt：

-keep class com.tonicartos.** { *; }
-dontwarn com.tonicartos.**

但发生此错误：

E/AndroidRuntime(6213): FATAL EXCEPTION: main
E/AndroidRuntime(6213): Process: com.myapp, PID: 6213
