在java构建路径下添加google play服务库

Question

我正在使用地图视图。我已将Google Play服务库添加到我的项目作为依赖项目，它工作正常。但是，如果我尝试将其导入到项目的libs文件夹中并将其添加到java构建路径下，则会出错。

我可以在java构建路径下添加google play服务库吗？如果不是，为什么？

错误显示在 控制台：

请帮我解决这个问题。

修改

我已将 dontwarn 添加到我的proguard.txt文件中，现在我可以导出我的应用程序了。

proguard的-project.txt

    -keepclassmembers class fqcn.of.javascript.interface.for.webview {
   public *;
}

-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;
}

-dontskipnonpubliclibraryclasses
-dontwarn com.google.**
-dontwarn android.support.v4.**

我在google上搜索过但 dontwarn 的概念对我来说并不清楚。任何人都可以解释一下 dontwarn 的作用，并且在混淆时使用它是否安全？< / p>

Answer 1

您必须将google-play-services-lib添加为库项目。他们更新了 SDK 。有几个教程。对于 Eclipse ，这很简单：

Right click project -> properties -> Android

Answer 2

Google Play服务的Proguard配置

-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;
}

您必须将Google Play服务导入为项目。然后转到您的项目属性，然后转到Android构建路径（您选择sdk版本），然后单击添加到Google Play服务项目。清理并构建它。
