Proguard with AbstractModule

Question

當我的android應用程序啓動時，會引發以下異常：

can't instantiate class com.project.modules.ClientServicesModule; no empty constructor 

我的模塊類看起來像下面這樣;

public class ClientServicesModule 
    extends AbstractModule 
{ 

    private Context context; 

    public ClientServicesModule(Context context) 
    { 
     this.context = context; 
    } 


    @Override 
    protected void configure(){ 

     .... 

     bind(new TypeLiteral<Dao<City, Integer>>() 
     { 
     }).toProvider(new DaoProvider<City, Integer>(OpenHelperManager.getHelper(context, DatabaseHelper.class).getConnectionSource(), City.class)) 
      .in(Singleton.class); 

     ... 
     } 
} 

我Proguard的文件：

-target 1.6 

-verbose 
-dump ../bin/class_files.txt 
-printseeds ../bin/seeds.txt 
-printusage ../bin/unused.txt 
-printmapping ../bin/mapping.txt

-keepclasseswithmembers class * { 
    public <init> (android.content.Context, android.util.AttributeSet); 
} 
-keepclasseswithmembers class * { 
    public <init> (android.content.Context, android.util.AttributeSet, int); 
} 
-keepclassmembers class * implements android.os.Parcelable { static android.os.Parcelable$Creator *; } 
-keepclassmembers class **.R$* { public static <fields>; } 
-keepclasseswithmembernames class * { native <methods>; } 
-keepclassmembers enum * { 
    public static **[] values(); 
    public static ** valueOf(java.lang.String); 
} 
-keepclassmembers class * extends android.app.Activity { 
    public void *(android.view.View); 
} 
-keepclassmembers class * { 
    @com.google.inject.Inject <init>(...); 
    @com.google.inject.Inject <fields>; 
    @javax.annotation.Nullable <fields>; 
} 
-keepclassmembers class * { 
    void *(net.eworldui.videouploader.events.*); 
} 
-keepclassmembers class * { 
    void *(roboguice.activity.event.*); 
} 

我的ProGuard配置工作，如果我添加一個空的構造函數，但隨後道不會加載爲空被傳遞到數據庫幫手。

如果我從我的pom.xml中刪除ProGuard步驟，一切都按預期工作。

的問題是如何使proguard的，這樣的模塊類可以與上下文中傳遞啓動。

謝謝。

Answer 1

嘗試下面的行添加到您的Proguard.config：

-keep public class * extends com.project.modules.ClientServicesModule { 
    <fields>; 
    <methods>; 
} 

，看看問題是否解決

編輯：

您可以通過定義保持整個命名空間：

-keep class com.project.modules.** {*;} 

如果有效，您可以嘗試排除其他不需要的人。看看我的第一個編輯
