使用Proguard构建Android APK并获取类not found异常

我一直在尝试用proguard创建一个Android APK。该应用程序在安装时可以工作，但当它试图使用com.google.android.gms.common.images.ImageManager中的对象时，就会抛出以下异常。我正在尝试将这个类用于Google Play游戏服务

在proguard-project.txt中，我有以下内容，但仍然不够好：

-keep class com.google.android.gms.common.images.** { *; }
#Google Play service
-keep class * extends java.util.ListResourceBundle {
    protected Object[][] getContents();
}

以下是project.properties文件，以防万一：

你看到这个了吗

前进问题

如果您正在使用Proguard，并且在模糊的APK上看到错误， 检查AndroidManifest.xml上的目标API级别。确保 将其设置为17或更高

---

在您的proguard文件中添加

-dontwarn com.google.android.gms.*

。

谢谢您的建议。我将android:targetSdkVersion=“17”改为17，但图像管理器仍然存在问题。这似乎是Google Play Game服务的jar文件的问题。我从第8版抓起一个罐子，proguard开始工作。很奇怪。
