ProGuard的后坠毁的Andr​​oid应用

问题描述

我的应用程序崩溃的ProGuard后，我试图找到答案，但我没有发现任何东西。

logcat的堆栈跟踪

  W / SupportMenuInflater（13657）：无法实例化类：android.support.v7.widget.ShareActionProvider
W / SupportMenuInflater（13657）：抛出java.lang.ClassNotFoundException：android.support.v7.widget.ShareActionProvider

这是我的proguard.cfg文件，这是默认的版本，我并没有改变它

 ＃这是ProGuard的配置文件。

＃请注意，如果要启用优化，你不能只是
＃在你自己的项目配置文件的优化参数;

＃支持库包含对新版本的平台。
＃不发出警告的情况下这个程序是针对连接的旧
＃平台版本。我们了解他们，他们是安全的。
-dontwarn android.support。**
 

`

修改：问题是解决，我说这行proguard.cfg并没有错误。随着新生产线忽略来自ProGuard的支持库

  -dontwarn android.support.v4。**
-keep类android.support.v4 ** {*。 }
-dontwarn android.support.v7。**
-keep类android.support.v7 ** {*。 }
 

解决方案

在你的ProGuard的配置，你已经注释掉类，它无法找到的保持：

 ＃ - 保持公共类android.support.v7.widget.ShareActionProvider
 

你尝试再次取消注释和建筑？

编辑：由于没有解决不了你的问题，也许尝试这里描述的所有陷阱：

Android为V7支持库动作条 Proguard的配置。

具体，试着加入：

  -keep类android.support.v7.internal ** {*。 }
-keep接口android.support.v7.internal ** {*。 }
-keep类android.support.v7 ** {*。 }
-keep接口android.support.v7 ** {*。 }
 

您就可以使之更具体是否可行，因为这显然只是让所有的支持库类，甚至你不要使用。

My application crashes after proguard, I tried to find answer for this but I did not find anything.

This is my proguard.cfg file, this is default version, I have not changed it

# This is a configuration file for ProGuard.
# http://proguard.sourceforge.net/index.html#manual/usage.html

-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-verbose

# Optimization is turned off by default. Dex does not like code run
# through the ProGuard optimize and preverify steps (and performs some
# of these optimizations on its own).
-dontoptimize
-dontpreverify
# Note that if you want to enable optimization, you cannot just
# include optimization flags in your own project configuration file;
# instead you will need to point to the
# "proguard-android-optimize.txt" file instead of this one from your
# project.properties file.

-keepattributes *Annotation*
-keep public class com.google.vending.licensing.ILicensingService
-keep public class com.android.vending.licensing.ILicensingService
#-keep public class android.support.v7.widget.ShareActionProvider

# For native methods, see http://proguard.sourceforge.net/manual/examples.html#native
-keepclasseswithmembernames class * {
    native <methods>;
}

# keep setters in Views so that animations can still work.
# see http://proguard.sourceforge.net/manual/examples.html#beans
-keepclassmembers public class * extends android.view.View {
   void set*(***);
   *** get*();
}

# We want to keep methods in Activity that could be used in the XML attribute onClick
-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

# For enumeration classes, see http://proguard.sourceforge.net/manual/examples.html#enumerations
-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 **.R$* {
    public static <fields>;
}

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**

`

EDIT: the problem was solved, I added this lines to proguard.cfg and have no errors. With new lines ignored support libraries from proguard

-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }

解决方案

In your proguard config, you have commented out the keep of the class that it can't find:

#-keep public class android.support.v7.widget.ShareActionProvider

Did you try uncommenting that and building again?

EDIT: since that didn't solve your problem, maybe try the catch all described here:

Android Proguard configuration for the v7 Support Library ActionBar

specifically, try adding:

-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

You can then make it more specific if that works, because this obviously just keeps all the support library classes, even ones you don't use.
