Can't upload Android app to device (stale dexed jars)
提问by Guilherme
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:
我正在使用 Android Studio 开发这个应用程序，今天当我尝试将它上传到我的设备进行测试时，我收到一个弹出窗口，上面写着：
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.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
安装失败，因为设备可能具有与当前版本不匹配的过时 dexed jar（dexopt 错误）。为了继续，您必须卸载现有的应用程序。
警告：卸载将删除应用程序数据！
您要卸载现有的应用程序吗？
It gave two options, OK or Cancel. Upon hitting OK, the following message showed up in the Run tab:
它提供了两个选项，确定或取消。点击“确定”后，“运行”选项卡中会显示以下消息：
DEVICE SHELL COMMAND: pm uninstall my.bundle.idUnknown failure
DEVICE SHELL COMMAND: pm uninstall my.bundle.idUnknown failure
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.
该应用程序似乎已被卸载，在“管理应用程序”下没有任何痕迹。
我无法上传应用程序。我尝试清理项目并重建，但没有奏效。
What can I do?
我能做什么？

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.
我发现 dex 文件变得比缓冲区大，即使它包含的方法少于 64k。然后我启用了 ProGuard，它大大减少了 dex 文件的大小。
THe application dex-method-countshelps a lot to debug your dex file, by checking not only the number of methods, but to what package they belong
dex-method-counts应用程序对调试 dex 文件有很大帮助，不仅可以检查方法的数量，还可以检查它们属于哪个包

I have also encountered this problem in Android Studio, from version 2.0 Preview 6 all the way up to 2.0 Beta 3 and none of the solutions mentioned here worked for me.
我在 Android Studio 中也遇到过这个问题，从 2.0 Preview 6 一直到 2.0 Beta 3，这里提到的解决方案都不适合我。
Turned up it had nothing to do with Instant Run. All I had to do was to increase the AVD's Internal Storage until the following notification disappeared. I also had to perform a data wipe after changing the values.
结果发现它与 Instant Run 无关。我所要做的就是增加 AVD 的内部存储，直到以下通知消失。更改值后，我还必须执行数据擦除。

I disabled Instant run for this project, and problem solved.
我为这个项目禁用了 Instant run，问题解决了。
Maybe it's a bug in the instant run feature of Android studio 2.0 preview.
可能是Android studio 2.0预览版即时运行功能的一个bug。
Instant Runis a new feature introduced in Android Studio 2.0.
Instant Run是 Android Studio 2.0 中引入的一项新功能。
ps: in case you don't find Instant run, its in:
ps：如果你没有找到 Instant run，它在：
Android Studio --> Preferences --> Build, execution, deploy --> Instant run.
or you can search for it in the preferences tab.
或者您可以在首选项选项卡中搜索它。

Go to AVD Manager, then in the action section of your device select wipe data. This worked for me, hope it helps....
转到 AVD 管理器，然后在设备的操作部分选择擦除数据。这对我有用，希望它有帮助......

I found out my problem was caused by old SDK Build Tools version, which was causing the Clean to fail. I upgraded my SDK Build Tools to the newest version and after that cleaning worked, and I no longer received the stale dexed jars error. Hopefully this will help someone else struggling with this issue.
我发现我的问题是由旧的 SDK Build Tools 版本引起的，这导致 Clean 失败。我将我的 SDK 构建工具升级到最新版本，在清理工作之后，我不再收到陈旧的 dexed jars 错误。希望这会帮助其他人在这个问题上挣扎。

This worked for me:
这对我有用：
In Android Studio this can be done by clicking on Build > Clean Project. SysadminTips
在 Android Studio 中，这可以通过单击Build > Clean Project来完成。系统管理员提示

When your dex file gets larger then buffer size( i.e. contains more than 65k methods) then this error occurs. You can avoid this error in two ways: 1.) Remove unused code with ProGuard - Configure the ProGuard settings for your app to run ProGuard and ensure you have shrinking enabled for release builds. Enabling shrinking ensures you are not shipping unused code with your APKs.
当您的 dex 文件变得大于缓冲区大小（即包含超过 65k 个方法）时，就会发生此错误。您可以通过两种方式避免此错误：1.) 使用 ProGuard 删除未使用的代码 - 为您的应用配置 ProGuard 设置以运行 ProGuard，并确保您已为发布版本启用收缩。启用收缩可确保您的 APK 不会附带未使用的代码。
2.) You can configure your app for multidex support. Refer this link to use it: https://developer.android.com/tools/building/multidex.html
2.) 您可以配置您的应用程序以支持多索引。请参阅此链接以使用它：https: //developer.android.com/tools/building/multidex.html
For multidex support I override this method in my application class:
对于 multidex 支持，我在我的应用程序类中覆盖了这个方法：
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
and modify my build.gradle like this:
并像这样修改我的 build.gradle：
android {
compileSdkVersion 21
buildToolsVersion "21.1.1"
defaultConfig {
minSdkVersion 14 //lower than 14 doesn't support multidex
targetSdkVersion 21
// Enabling multidex support.
multiDexEnabled true
}
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
Hope it helps!
希望能帮助到你！

In my project I got past this by being more specific about which portions of Google Play Services I was linking with. In particular, I changed
在我的项目中，我通过更具体地说明我正在链接的 Google Play 服务的哪些部分来解决这个问题。特别是，我改变了
dependencies {

compile 'com.google.android.gms:play-services:8.4.0'
}
to
到
dependencies {

compile 'com.google.android.gms:play-services-maps:8.4.0'

in my app module's build.gradle, since all I was really using was the maps API.

In my case was because my emulator was full of apps. I saw how much space the emulator had and was almost nothing so I deleted some apps and with this my problem was resolved
就我而言，是因为我的模拟器充满了应用程序。我看到模拟器有多少空间，几乎什么都没有，所以我删除了一些应用程序，这样我的问题就解决了
