保护Google Play服务7. +会导致com.google.android.gms.internal.zzig：找不到引用的方法'boolean isAttachedToWindow（）'

Question

我有一个接近65K方法计数限制的应用程序。 我目前正在使用Proguard且没有混淆

# This is a configuration (rules) file for ProGuard.
-dontobfuscate
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers

# Dex does not like code run through the ProGuard optimize and preverify steps
# (and performs some of these optimizations on its own).
-dontpreverify
-dontoptimize
-verbose

# Only run ProGuard shrinking against Google Play Services (package = com.google.android.gms.*)
-keep class !com.google.** (also tried !com.google.android.** / !com.google.android.gms.**)
-dontwarn !com.google.** (also tried !com.google.android.** / !com.google.android.gms.**)

去除依赖项中未使用的方法：

compile 'com.google.android.gms:play-services-base:7.5.0'
compile 'com.google.android.gms:play-services-location:7.5.0'
compile 'com.google.android.gms:play-services-ads:7.5.0'
compile 'com.google.android.gms:play-services-gcm:7.5.0'
compile 'com.google.android.gms:play-services-identity:7.5.0'

但是，$ ./gradlew汇编给出以下错误：

:proguardGoogleDebug
Warning: com.google.android.gms.internal.zzig: can't find referenced method 'boolean isAttachedToWindow()' in program class com.google.android.gms.internal.zzig
Warning: there were 1 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedprogramclassmember)
:proguardGoogleDebug FAILED
FAILURE: Build failed with an exception.

有人解决过这个问题吗？ 提前致谢。

确保您的compileSDK为> =19。View＃isAttachedToWindow已在19中添加。
