使用android map utils library生成已签名apk的错误

Question

由于我添加了这个依赖项，我无法再生成已签名的APK。古怪，构建/编译APK工作，但构建/生成APK签署失败，这些行：

Warning:com.google.maps.android.clustering.ClusterManager: can't find superclass or interface com.google.android.gms.maps.GoogleMap$OnCameraIdleListener 
Warning:com.google.maps.android.clustering.ClusterManager: can't find referenced class com.google.android.gms.maps.GoogleMap$OnCameraIdleListener 
Warning:com.google.maps.android.kml.KmlRenderer: can't find referenced method 'void setZIndex(float)' in program class com.google.android.gms.maps.model.Marker 
Warning:there were 4 unresolved references to classes or interfaces. 
Warning:there were 1 unresolved references to program class members. 
Warning:Exception while processing task java.io.IOException: Please correct the above warnings first. 
Error:java.lang.RuntimeException: java.io.IOException: Please correct the above warnings first. 
Error:java.io.IOException: Please correct the above warnings first. 
Information:BUILD FAILED 

这里是我的模块的build.gradle依赖部分：

apply plugin: 'com.android.model.library' 
apply plugin: 'com.google.gms.google-services' 

dependencies { 
    compile 'com.google.android.gms:play-services-maps:9.0.2' 
    compile 'com.google.maps.android:android-maps-utils:0.4+' 
} 

model 
{ 
    [etc...] 
} 

而且这是项目一级：

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle-experimental:0.8.0' 
     classpath 'com.google.gms:google-services:3.0.0' 

     // NOTE: Do not place your application dependencies here; they belong 
     // in the individual module build.gradle files 
    } 
} 

Answer 1

可能Proguard的（这是做的工作），当您试图生成APK签署（发行版），你可以解决这个问题通过增加

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

，但通常这是在地图图书馆已经完成，我会建议使用最新版本在你面前的地图LIB尝试上面的解决方案

com.google.android.gms:play-services-maps:9.8.0
