启用Proguard后，“应用程序停止工作”

Question

这是一个工作中的应用程序，可以在模拟器和测试设备上运行。

但是现在，我启用了Proguard并使用Android-Tools > 导出已签名应用程序导出了签名的应用程序。

然后，我将此.apk复制到SD卡上，并尝试在设备上安装。但是该应用程序停止工作，如果我尝试打开它，则会要求强制关闭。

如果从Eclipse运行，则它在设备上正常工作。

因为说：

只有在导出发布的.apk文件时，Proguard才会生效。我检查了一下，在bin文件夹中的apk文件大小为1.8mb，而导出后得到的是1.4mb。看起来Proguard已经完成了它的工作。但是应用程序无法工作。可悲的是我无法看到任何日志等...

编辑：

如果我禁用Proguard，然后导出，发布的apk文件现在可以正常工作。所以，Proguard存在问题吗？

我今天刚开始使用它，不确定我是否使用正确。如果有错误，请纠正我。 这是LogCat错误：

是的，我已经尝试了3-4次，但都没有成功。实际上，禁用Proguard后问题就解决了。因此，我认为问题出在Proguard上，而不是导出方面。 - Archie.bpgc

与大多数未经解释的崩溃/强制关闭一样，除非您发布崩溃时的logcat错误，否则其他人无法帮助您。这将提供关键线索，以确定在proguard操作中出现了什么问题，因此需要更改proguard配置。 - Chris Stratton

@ChrisStratton 但是我该如何获取日志呢？我应该从配置文件中删除与日志相关的代码，然后在模拟器上安装apk吗？ - Archie.bpgc

我在你的文件中没有看到任何“-libraryjars”条目，我记得我也需要插入它们，尝试像这样添加它们“-libraryjars libs/android-support-v4.jar”。 - Tomer Mor

我不确定，所以请先尝试参考文献。 - Tomer Mor

堆栈跟踪显示ActionBarSherlock在使用反射时找不到构造函数"a(Activity,int)"。其文档确实指定了每个ActionBarSherlock扩展都应该具有此构造函数。由于该构造函数在代码中似乎未使用，ProGuard无法知道这一点并已将其删除。因此，您需要明确告诉ProGuard保留它：

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

一般来说，如果您在代码或其库中遇到与反射相关的堆栈跟踪，您需要添加相应的配置。
