【问题描述】：

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

# 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.**)

去除其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 assemble 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.

以前有人解决过这个问题吗？提前致谢。

【参考方案1】：

确保您的 compileSDK >= 19。View#isAttachedToWindow 是在 19 中添加的。
