＆QUOT;应用停止工作＆QUOT;使Proguard的后 [英] "Application stopped working" after enabling Proguard

问题描述

这是一个工作的应用程序，无论是在模拟器，我测试的设备。

It was a working app, both on emulator and the device i am testing on.

但现在，我启用的 Proguard的并导出使用 Android的工具＆gt签名的应用程序;出口签名的应用程序

But now, i enabled Proguard and Exported the signed app using Android-Tools > Export signed application

然后我复制这个 .apk文件到SD卡上，并试图安装在设备上。但是，应用程序停止工作，要求强制关闭，如果我尝试打开它。

Then i copied this .apk on to the SD card and tried to install on the Device. But the application stopped working, asking for force close if i try to open it.

它的工作原理在设备上，如果我从Eclipse中运行。

It works on the device if i run from Eclipse.

一直以来，公司称：的

Proguard的只有效果，当你导出版本的apk文件。我检查，并在 APK 的bin文件夹中的文件大小为 1.8MB 其中的1我出口后，得到的是 1.4MB 。好像Proguard的已完成其工作。但是，应用程序无法正常工作。而可悲的是我看不到任何日志等。

Proguard has effect only when you export a release .apk file. I checked it, and the apk file size in the bin folder is 1.8mb where as the 1 i got after exporting is 1.4mb. Seems like Proguard has done its job. But the application is not working. And sadly i cannot see any logs etc..,

编辑：

如果我禁用Proguard的，然后出口，释放apk文件现在能正常工作。所以，有些问题Proguard的？

If i disabled Proguard and then Exported, the release apk file works fine now. So, some problem with Proguard?

我刚开始使用它的今天，我不知道如果我使用的正确方法。所以，请纠正我，如果我错了，任何地方。

I just started using it today, and i am not sure if i am using it the right way. So, please correct me if i am wrong anywhere.

这是LogCat中的错误：

推荐答案

堆栈跟踪显示ActionBarSherlock未能找到一个构造函数一个（活动，INT）使用反射。它的文件确实规定ActionBarSherlock的每个分机都应该有这样一个构造函数。 ProGuard的不会（也不能）知道这一点，已取消的构造，因为它似乎不用在code。因此，你必须明确地告诉ProGuard的，以保持它的：

The stack trace shows that ActionBarSherlock is failing to find a constructor "a(Activity,int)" using reflection. Its documentation indeed specifies that each extension of ActionBarSherlock should have such a constructor. ProGuard doesn't (can't) know this and has removed the constructor, because it appears unused in the code. You therefore have to explicitly tell ProGuard to keep it:

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

在一般情况下，如果你在你的code或它的库与反思这样的堆栈跟踪，需要添加相应的配置。

In general, if you get such stack traces related to reflection in your code or its libraries, you need to add corresponding configuration.
