这个错误让我发疯。从 Google Play 商店下载时，我的应用程序在启动时崩溃并出现以下错误：

java.lang.ClassNotFoundException
in dalvik.system.BaseDexClassLoader.findClass

在我们的两台设备上从 eclipse 构建时，我的应用程序不会崩溃。然而一个月前，一位客户使用他的手机构建了我们的应用程序，然后它在启动时也崩溃了。我当时忽略了这个问题，因为它在我们的设备上运行，并认为它与谷歌地图密钥或密钥库有关。

现在事实证明，当从 Play 商店下载时，我们的应用程序在每台设备上都会崩溃。我知道没有一种简单的方法可以解决这个问题，但我们将不胜感激朝着正确的方向前进。

我也发现很难调试这个问题，因为在我们的设备上从 eclipse 构建应用程序时效果很好！

这是我报告的完整错误日志：

再说一次，我除了直接回答这个问题之外，也许有人可以通过这个错误日志来解释这个问题。

所以确实是 ProGuard 从我的项目中剥离了代码。我使用 ActionBarSherlock 和 facebook，这是我添加的，所以它可以工作：

# ActionBarSherlock 

-keep class android.support.** { *; } 

-keep interface android.support.** { *; } 

-keep class com.actionbarsherlock.** { *; } 

-keep interface com.actionbarsherlock.** { *; } 




# Keep line numbers to alleviate debugging stack traces 

-renamesourcefileattribute SourceFile 

-keepattributes SourceFile,LineNumberTable

这是脸书：

-keepclassmembers class * implements java.io.Serializable
{
    private static final java.io.ObjectStreamField[] serialPersistentFields;
    private void writeObject(java.io.ObjectOutputStream);
    private void readObject(java.io.ObjectInputStream);
    java.lang.Object writeReplace();
    java.lang.Object readResolve();
}

好吧，我建议您关注您从 eclipse 进行的构建与您提供给 Play 商店的构建之间的区别。

如果您可以重现您从 playstore 中看到的错误，同时使用 eclipse 构建并测试它，您肯定会找到答案。

我能想到的是应用程序获得签名的证书，但似乎并非如此。但是，您应该更多地考虑两个 .apk 之间的区别 - 开发人员构建和 Playstore 构建。

由于 .apk 基本上是档案，您可以将它们都解压缩，查看它们之间的差异。您应该使用 dedexer 尝试反编译 classes.dex 的两个实例（请参阅将DEX 反编译为 Java 源代码）。它可能是高度混淆的代码，但您应该寻找丢失的类或类似的东西。

希望你做对了。

右键单击您的项目文件夹 => 属性 => Java 构建路径 => 订购和导出 => 如果未选中，请选中“Android Private Libraries”框。它有效！
