启用Proguard后，Android应用程序崩溃

Question

每次我从Eclipse导出签名应用程序并将apk文件安装到手机上时，该应用程序都会崩溃。这仅在启用Proguard的情况下发生。

这是我的保护文件

-libraryjars /libs/firebase-client-android-2.2.3.jar
-libraryjars /libs/android-support-v4.jar

}

-keep public class * extends com.android.partysearch.ChatApplication
-keepclassmembers class * extends com.android.partysearch.ChatApplication{
 public <init>(android.content.Context);
}


-keep public class org.spongycastle.** {

}

-keep public class org.apache.** {

}

-ignorewarnings

-keepclasseswithmembernames class * {

}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}


-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-keepclassmembers class * implements java.io.Serializable {
    static final long serialVersionUID;
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

我运行了adb logcat命令来检查崩溃报告。以下是我认为很重要的报告摘要：

第二段：

如果有人可以帮助我，我将非常感谢并接受您的回答。

更新： 所以我将这些添加到我的proguard文件中

-keepattributes Signature
-keep class com.firebase.** { *; }
-keep class org.apache.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }
-dontwarn org.w3c.dom.**
-dontwarn org.joda.time.**
-dontwarn org.ietf.jgss.**

现在启用Proguard时出现与Jackson相关的错误。如果Proguard被禁用，该应用程序仍然可以运行。这是崩溃日志的片段：

E/AndroidRuntime( 6032): Caused by: com.shaded.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "time" (class com.partysearch.Room), not marked as ignorable (5 known properties: , "note", "level", "userName", "console", "gametype"])

我终于解决了。这就是我忘记添加到Proguard文件中的内容。吸气剂和吸气剂。

-keep public class com.example.YourModelClassName {
  public *** get*();
  public void set*(***);
}
