[英]signed vs unsigned apk: classDeffNotFound

原文 2013-07-17 05:43:57 8 1 android/ eclipse/ apk

I have been developing for android for a while, and have never encountered the following problem. 我已经开发了一段时间的android，并且从未遇到过以下问题。

I inherited a codebase that I am trying to move from hockey app to google play. 我继承了一个代码库，我试图从曲棍球应用程序转移到谷歌播放。 When I distribute the apk obtained from the bin directory, everything works fine. 当我分发从bin目录获取的apk时，一切正常。 However, when I export a signed apk, the app crashes claiming that one or another class is not found. 但是，当我导出已签名的apk时，应用程序崩溃声称找不到一个或另一个类。 The classes in question are classes that I create myself. 有问题的课程是我自己创建的课程。 And they are in the main package; 它们属于主要包装; so no dependency issues that I can see. 所以没有我能看到的依赖性问题。

Has anyone encountered this type of problem where bin apk works fine but not the signed apk? 有没有人遇到这种类型的问题，其中bin apk工作正常，但没有签名的apk？ I am not using proguard. 我没有使用proguard。 And I am using exclipse to export this app; 我正在使用exclipse导出这个应用程序; similar to how I have always exported other apps. 类似于我总是导出其他应用程序。

The problem cannot be the key used to signed. 问题不能成为签署的关键。 As far as I know, if the key were corrupted, it would not create the apk at all. 据我所知，如果密钥已损坏，它根本不会创建apk。

The problem persists whether I email the apks or install them with USB. 无论是通过电子邮件发送apks还是使用USB安装它们，问题仍然存在。

1 个解决方案

Try: 尝试：

1) Remove bin folder. 1）删除bin文件夹。

2) Rebuild project.[Eclipse will rebuild if 'Build automatically' is checked under 'Project' menu tab] 2）重建项目。[如果在“项目”菜单选项卡下选中“自动构建”，Eclipse将重建]

3) Now try creating signed apk. 3）现在尝试创建签名的apk。

I am facing this problem once in a while. 我偶尔会遇到这个问题。 I have been successful with above steps. 我已经成功完成了上述步骤。 If still problem persists, I will restart eclipse then follow same steps again. 如果问题仍然存在，我将重新启动eclipse，然后再次执行相同的步骤。
