安装应用程序后，发行版本看不到应用程序类 [英] Release version doesn't see Application class after installing the app

问题描述

在调试版本中，应用程序运行正常.但是，当我生成sign apk并安装它时，在打开应用程序后-由于logcat错误，它立即崩溃:

In a debug version app works fine. But when I generate sign apk and install this, after open app - it immediately crashes due to a logcat error:

 Caused by: java.lang.ClassNotFoundException: Didn't find class "com.mypackage.AppClass" on path: DexPathList[[zip file "/data/app/com.mypackage-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]].

我使用AppClass扩展MultiDexApplication，并且那里也有一些功能.我已经在清单中正确声明了该类.

I use AppClass to extends MultiDexApplication and I've got there some functions also. I have declared this class correctly in a manifest.

最复杂的是它可以在调试版本中工作，但仅在发行版中会出现此问题.

The most complicated is that it works in a debug version but only in release version this problem occurs.

如果有人可以帮助我解决这种情况，我将非常感激.

I would be really grateful if someone could help me to resolve this situation.

致谢

推荐答案

最后，我找到了一个解决方案，可以帮助我解决此问题.我必须将这部分代码添加到gradle中:

Finally, I found a solution which helped me to resolve this problem. I had to add this part of code in a gradle:

  dexOptions {
      preDexLibraries = false
   }

以下是您应用的一般部分build.gradle

And the following to the general part of your apps build.gradle

afterEvaluate {
   tasks.matching {
      it.name.startsWith('dex')
   }.each { dx ->
      if (dx.additionalParameters == null) {
         dx.additionalParameters = ['--multi-dex']
      } else {
         dx.additionalParameters += '--multi-dex'
      }
   }
}
