启用Proguard后“应用程序停止工作”

Question

这是一个有效的应用程序，无论是在模拟器上还是我正在测试的设备上。

但是现在，我已启用 Proguard 并使用Android-Tools > Export signed application导出已签名的应用

然后我将此.apk复制到SD卡上并尝试在设备上安装。但是应用程序停止工作，如果我试图打开它，请求关闭力量。

如果我从Eclipse运行，它可以在设备上运行。

因为，它说：

Proguard仅在导出发行版.apk文件时有效。我查了一下，bin文件夹中的 apk 文件大小是 1.8mb ，其中导出后的1是 1.4mb 。似乎Proguard已经完成了它的工作。但该应用程序无法正常工作。可悲的是，我看不到任何日志等..，

修改

如果我禁用Proguard然后导出，则发布apk文件现在正常工作。那么，Proguard存在一些问题？

我的文件夹结构

我今天刚开始使用它，我不确定我是否正确使用它。所以，如果我在任何地方都错了，请纠正我。

谢谢

堆栈跟踪显示ActionBarSherlock无法使用反射找到构造函数“a（Activity，int）”。它的文档确实指定ActionBarSherlock的每个扩展都应该有这样的构造函数。 ProGuard不会（​​不能）知道这一点并删除了构造函数，因为它在代码中似乎未使用。因此，您必须明确告知ProGuard保留它：

-keepclassmembers class * extends com.actionbarsherlock.ActionBarSherlock {
    <init>(android.app.Activity, int);
}

通常，如果在代码或其库中获得与反射相关的堆栈跟踪，则需要添加相应的配置。
