Question

我有android应用程序。当我在我的日食上运行或调试应用程序时，它可以顺利运行没有错误没有警告。之后我得到了Google for Google play。当用户从谷歌游戏市场下载时，它们会出现以下错误。请帮帮我，我无法解决这个问题。它找不到一些课程。

这是从开发者控制台获取的错误;

Answer 1

我遇到了类似的问题

在我的情况下，由于即时运行而发生这种情况，只需禁用它

转到：

Android Studio - ＆gt;档案 - ＆gt;设置 - ＆gt;构建，执行，部署 - ＆gt;即时运行。

Answer 2

请以正确的方式链接您的lib，您的库不会与您的应用程序一起编译，如果您使用的是第三方库，请确保在链接它们时将它们复制到项目中。链接库的屏幕截图可以提供更多帮助。

另外在旁注中，尝试在处理库时，比Eclipse更好地转移到Android Studio。

Answer 3

它说 -

java.lang.ClassNotFoundException: Didn't find class "com.versus.hit.yeni.ACProgressFlower$Builder"

检查您正在调用的是否存在于同一路径上的bin文件夹中，如果不尝试再次添加与@ahmad said相同的库，或者清理项目并再次运行。 NoClassDefFoundError表示类加载器无法找到您尝试使用的类的.class文件。

Answer 4

我通过改变

解决了我的问题

classpath 'com.android.tools.build:gradle:2.0.0-beta2'

到

classpath 'com.android.tools.build:gradle:1.3.0'

在build.gradle文件中。我不知道为什么这解决了这个问题。这可能是测试版中的错误。

Answer 5

卸载应用
重新启动手机
重新安装应用

Answer 6

从Project文件夹中删除临时 .gradle 文件夹。

Answer 7

在我的情况下，它发生是因为我移动了项目位置。我删除了＆＃34; .gradle＆＃34;包主模块，然后解决问题。

Answer 8

如果你不对你的项目做任何事情，但抓住这个问题，你可以试试。 Android对我来说是新手，所以当我遇到这个问题时，我会清除所有自动生成的文件，包括{studio}的.gradle，.build等。有用！享受你的编码！

Answer 9

您似乎在发布buildTypes的gradle文件中有minifyEnabled true，在调试中有minifyEnabled false。

如果是这样，请尝试添加您的 proguard-rules.pro 文件：

-keep class com.versus.hit.yeni.ACProgressFlower$Builder
-keep class com.versus.hit.yeni.JSONParser

引起：java.lang.NoClassDefFoundError：使用引导类加载器找不到类;没有堆栈可用
