Android - twitter4j Proguard錯誤

Question

我有問題試圖混淆我的apk - 與this SO question報告相同的問題。我應用了該問題的接受答案，然後創建了我的apk。

但是，當我運行我的應用程序時，它會在第一個啓動畫面顯示之前崩潰。

如何調試這個和/或是否有任何可能從我的proguard的-project.txt文件丟失?? ...

# To enable ProGuard in your project, edit project.properties 
# to define the proguard.config property as described in that file. 
# 
# Add project specific ProGuard rules here. 
# By default, the flags in this file are appended to flags specified 
# in ${sdk.dir}/tools/proguard/proguard-android.txt 
# You can edit the include path and order by changing the ProGuard 
# include property in project.properties. 
# 
# For more details, see 
# http://developer.android.com/guide/developing/tools/proguard.html 

# Add any project specific keep options here: 

# If your project uses WebView with JS, uncomment the following 
# and specify the fully qualified class name to the JavaScript interface 
# class: 
#-keepclassmembers class fqcn.of.javascript.interface.for.webview { 
# public *; 
#} 

-dontwarn twitter4j.** 

NB - 我還使用android- support-v4.jar和acra-4.5.0.jar庫在我的應用程序。

看起來像有一些問題。在最後分類。如果它幫助其他人，這裏是我的完整proguard-project.txt文件：

# 
# Add project specific ProGuard rules here.

-keep public class com.example.SplashActivity 
-keep public class com.example.FragmentActivityWithListener

# ACRA needs "annotations" so add this...

-keepattributes *Annotation* 

# keep this class so that logging will show 'ACRA' and not a obfuscated name like 'a'. 
# Note: if you are removing log messages elsewhere in this file then this isn't necessary 
-keep class org.acra.ACRA {

} 

# keep this around for some enums that ACRA needs

將-keep class twitter4j.** { *; }加到您的proguard-project.txt文件中。
