Android应用程序无法上传到设备（过时dexed罐子） [英] Can't upload Android app to device (stale dexed jars)

问题描述

我使用的是Android Studio开发这个程序，今天当我试图把它上传到我的设备来测试我有一个弹出式窗口说：

I am using Android Studio to develop this app, and today when I tried to upload it to my device to test I got a popup window saying:

安装失败，因为该设备可能有失效的dexed罐子不匹配当前版本（dexopt错误）。   为了继续，您必须卸载现有的应用程序。

Installation failed since the device possibly has stale dexed jars that don't match the current version (dexopt error). In order to proceed, you have to uninstall the existing application.

警告：卸载将删除该应用程序的数据。

WARNING: Uninstalling will remove the application data!

是否要卸载现有的应用程序？

Do you want to uninstall the existing application?

这给了两个选择，确定或取消。一旦击中OK，下面的消息显示，在Run标签：

It gave two options, OK or Cancel. Upon hitting OK, the following message showed up in the Run tab:

设备shell命令：下午卸载my.bundle.id
  未知故障

该应用程序似乎被卸载后，没有一丝它在管理应用程序。
我无法上传应用程序。我试图清理项目和重建，但没有奏效。

The app seems to be uninstalled, the is no trace of it under Manage Applications.
I am unable to upload the app. I tried cleaning the project and rebuilding, but it didn't work.

我该怎么办？

推荐答案

我发现DEX文件变得比缓冲大，即使它包含小于64K的方法。然后我启用ProGuard的，它帮助了很多降低DEX文件的大小。

I discovered that the dex file was getting larger than the buffer, even though it contained less than 64k methods. Then I enabled ProGuard and it helped a lot reducing the dex file size.

应用 DEX-方法，计数有很大帮助调试您的DEX文件，不仅受检查方法数，而是哪个包属于

THe application dex-method-counts helps a lot to debug your dex file, by checking not only the number of methods, but to what package they belong
