解析SDK的Android Proguard的問題

Question

我分析我的應用程序1.5.1，一切工作正常，但是當我去出口APK我得到：

[2014-09-05 19:53:08 - myapp] Proguard returned with error code 1. See console 
[2014-09-05 19:53:08 - myapp] Note: there were 662 duplicate class definitions. 
[2014-09-05 19:53:08 - myapp] Warning: com.parse.FacebookAuthenticationProvider$1: can't find superclass or interface com.facebook.android.Facebook$ServiceListener

在我proguard.cfg我有以下幾點：

-keepattributes *Annotation* 
-keep class com.parse.* { *; } 
-libraryjars libs/Parse-1.5.1.jar 

這讓我瘋狂！

Answer 1

你應該嘗試也在密切com.parse的子包：

-keepattributes *Annotation* 
-keep class com.parse.** { *; } 

不要添加-libraryjars選項，因爲Android編譯過程已經自動指定所有必要-injars，-outjars，並且-libraryjars爲您服務。它只會導致有關重複類的警告。

Answer 2

礦固定通過添加這樣的：

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