ProGuard的：找不到引用的类com.google.android.gms.R [英] ProGuard: can't find referenced class com.google.android.gms.R

问题描述

在在Android SDK中的经理有些更新我尽量使签署的apk，并得到这样的：

After some updates in Android SDK manager I try make signed apk and get this:

ProGuard: [] Warning: com.google.android.gms.auth.GoogleAuthUtil: 
  can't find referenced class com.google.android.gms.R
ProGuard: [] Warning: com.google.android.gms.auth.GoogleAuthUtil: 
  can't find referenced class com.google.android.gms.R$string
...
etc.

如果设置 -dontwarn com.google.android.gms。** 编译就可以了。但运行后，我得到的错误这样的很多报道（许多设备）：

If set -dontwarn com.google.android.gms.** compiling is OK. But after run I get error many reports like this (from many devices):

Caused by: android.view.InflateException: Binary XML file line #32: 
  Error inflating class com.google.android.gms.common.SignInButton

在我的设备一切ok。更新前我还没有ProGuard的警告和所有的工作完美。它是如何解决？

On my devices all ok. Before update I have not ProGuard warnings and all work perfectly. How it fix?

推荐答案

虽然将其加入 ProGuard的-project.txt 文件的作品，它让所有的类。

Although adding this to proguard-project.txt file works, it keeps all classes.

-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**

我$ P PFER这个$，这使得apk文件大小小很多：

I prefer this, which makes apk file size much smaller:

-keep public class com.google.android.gms.* { public *; }
-dontwarn com.google.android.gms.**

另外请注意最新的谷歌播放Proguard的通知在这里：<一href="http://developer.android.com/google/play-services/setup.html#Proguard">http://developer.android.com/google/play-services/setup.html#Proguard

-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

-keep public class com.google.android.gms.common.internal.safeparcel.SafeParcelable {
    public static final *** NULL;
}

-keepnames @com.google.android.gms.common.annotation.KeepName class *
-keepclassmembernames class * {
    @com.google.android.gms.common.annotation.KeepName *;
}

-keepnames class * implements android.os.Parcelable {
    public static final ** CREATOR;
}
