Android应用程序在Proguard混淆后崩溃

androidobfuscationproguard

我在我的应用上运行了proguard工具来混淆代码。我知道当混淆发生时，proguard会根据自己的判断来缩小和优化应用程序。因此，在混淆应用程序后，应用程序正确打开，但当我尝试登录时，它会崩溃。这是我连接设备时获得的最佳日志。

我曾认为这是因为Proguard删除了它认为不必要的某些类或方法，从而导致崩溃。我所做的是再次运行Proguard，这次包括

-dontobfuscate

我希望这个工具能够缩小和优化，但不要混淆，这样我就可以得到一个正确的读数，知道缺少了什么。然而，当我使用这个工具生成apk时，这次运行得非常完美。问题是它没有被混淆。

所以我现在不知道该怎么办了。

有人有什么想法吗？

*编辑*

这是我的配置文件

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:

-libraryjars libs/crashlytics.jar

-keep class com.facebook.** {
*;
}


-keepattributes Signature

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService

keep all classes that might be used in XML layouts
-keep public class * extends android.view.View
-keep public class * extends android.app.Fragment
-keep public class * extends android.support.v4.Fragment

-keepattributes *Annotation*, EnclosingMethod

-keep class com.winwin.** { *; }
-keepnames class org.codehaus.jackson.** { *; }


-dontoptimize
-dontshrink

keep all public and protected methods that could be used by java reflection
-keepclassmembernames class * {
 public protected <methods>;
}

-keepclasseswithmembernames class * {
native <methods>;
}

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

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


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

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

 -dontwarn **CompatHoneycomb
 -dontwarn org.htmlcleaner.*

 -dontwarn com.fasterxml.jackson.databind.ext.**

 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 *;
}

==========================

这是我的项目资源管理器面板。

android-support-v7-appcompat / ConverserSdk / facebook / google-play-services_lib / library / Main / MainWs / SlidingMenu

因此，我的主要内容依赖于其他每个包。

@GrIsHu 我的doInBackground()方法中没有getter或setter方法，但是在这个方法中有错误检查，如果出现错误，我会调用具有setter方法的方法..这可能是一个因素吗？ - DJ-DOO
不要将要混淆的类添加到你的proguard文件中，只需在proguard文件中添加包含该类包名的语句：-keep class reflection.using.package.name.** { *; }。 - GrIsHu
@laalto 是的，我在我的后台操作中有一些JSON映射器。在它说“-keep class reflection.using.package.name.**”时，我需要将其修改为“-keep class reflection.using.com.DJ-DOO.name.**”吗？ - DJ-DOO
@dj-doo 请将 reflection.using.package.name 替换为库的包名称。例如，如果是Jackson，则为 org.codehaus。（这可能会保留太多未混淆的内容，但可以给您一个更安全的起点。） - laalto
这是Jackson。不幸的是，我没有在这个Web服务上工作。这个应用程序中有很多Web服务调用。所以我将其更改为“-keep class org.codehaus.** {*;}”？ - DJ-DOO

您需要保留一些类不被混淆。一个典型的Android项目的Proguard配置文件如下所示。这个链接可能会有用：Proguard for Android

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keep public class * implements java.io.Serializable
-keep public class * extends android.support.v4.app.Fragment
-keep public class * extends android.support.v4.app.ListFragment



-keep public class org.spongycastle.** {
  <fields>;
  <methods>;
}

-keep public class org.apache.** {
  <fields>;
  <methods>;
}

-ignorewarnings

-keepclasseswithmembernames class * {
    native <methods>;
}

-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();
}
谢谢您的回复，我已经去过那里并且遵循了该网站的指导。 - DJ-DOO

快速工作解决方案。
-keep  class com.fasterxml.jackson.annotation.** {*;}
-keep  class com.fasterxml.jackson.core.** {*;}
-keep  class com.fasterxml.jackson.databind.** {*;}
如何知道要保留哪些类？ - W.M.
这取决于你使用的库。对于 Android，默认情况下会保留几个类。 - Vinayak
