android：错误转换字节到dex

所以，在升级build.gradle（Project）之后，运行项目时出现以下错误

dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha2' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } 

至

 dependencies { classpath 'com.android.tools.build:gradle:2.0.0-alpha3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } 

我刚把2.0.0-alpha2的gradle改成了2.0.0-alpha3 ，然后试图build立这个项目。

任何帮助，将不胜感激。

Answer 1

好的。 我不知道如何，但工作。

首先，我清理了这个项目，然后运行这个项目让一切顺利。

短暂的，先Clean然后Run 。

编辑第一次Clean ，然后Make Project也可以。

Answer 2

在我的情况下，我先Clean项目，然后按下Make Projectbutton， 如下图 ，然后开始工作。 Rebuild对我不起作用。

而且我也在更新Google Repository是必须的。

Answer 3

如果你正在使用任何插件。 然后，在您的模块Gradle文件（通常是app/build.gradle ）中，确保在文件底部添加apply plugin行以启用Gradle插件。

例如

Answer 4

我遇到了同样的问题，我干净的项目，一些其他问题导致无法清理，所以我手动删除目录'生成'，所以它可以清理好了，然后运行它为我好。

Answer 5

就我而言，我放了

apply plugin: 'com.google.gms.google-services'

在build.gradle文件的底部，并在defaultConfig中设置multiDexEnabled true 。 然后运行，它的工作。

Answer 6

我发现在我的情况下，这个问题是由不正确的build.gradleconfiguration造成的。 我有两个不同版本的com.google.firebase。 一旦版本相同，问题就解决了

Answer 7

我遇到了同样的问题。
首先从项目位置删除生成文件夹（您可以通过android studio或使用资源pipe理器访问它），然后build项目。

Answer 8

只需restart你的AS，然后Rebuild你的应用程序！

Answer 9

升级到Android Studio 2.1后，下一次重新启动时，我被要求升级到JDK 1.8。 升级到JDK 1.8之后，这就是我的AS项目在编译时遇到的问题。 我遵循了这个页面的所有build议，但是无济于事。 最后，我决定检查我的项目正在使用的JDK版本，而令我惊讶的是，它不知何故指向JDK 1.8！

道德故事：如果compileSdkVersion <= 23，请仔细检查您的项目是否使用JDK1.7，如下所示：

• 右键单击顶级模块
• 项目结构=> JDK位置

Answer 10

在我的情况下，这个问题是因为在一些包中的大写字母。

Answer 11

在我的情况下，这是由于我的库不被configuration为“机器人”。 例如， apply plugin:'java'而不是apply plugin:'com.android.library'

Answer 12

检查你build.gradle（模块： 你的应用程序 ）。

所有com.google.android.gms库必须使用完全相同的版本规范（混合版本可能会导致运行时崩溃）。

例如：如果您有com.google.firebase：firebase-ads： 9.6.1和com.google.android.gms：play-services-basement： 10.0.1

您必须将Firebase版本更改为： 10.0.1

Answer 13

之前：

 compile 'com.google.android.gms:play-services-location:10.0.1' compile 'com.google.android.gms:play-services-auth:10.0.1' compile 'com.google.firebase:firebase-database:10.2.0' compile 'com.google.firebase:firebase-core:10.2.0' compile 'com.google.firebase:firebase-messaging:10.2.0' 

后：

 compile 'com.google.android.gms:play-services-location:10.2.0' compile 'com.google.android.gms:play-services-auth:10.2.0' compile 'com.google.firebase:firebase-database:10.2.0' compile 'com.google.firebase:firebase-core:10.2.0' compile 'com.google.firebase:firebase-messaging:10.2.0' 

终于解决了。

Answer 14

由于某些原因，@ ChintanSoni的答案没有奏效。 我尝试手动删除生成文件夹，但不能删除某些文件，因为它们被某些进程使用。 清理和重新构build项目并没有帮助，所以我打开task manager ，select了JAVA(TM) Platform SE binary并按下了“结束任务”。

然后我试图再次运行该项目，并开始编译。

Answer 15

 dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') compile fileTree(include: 'Parse-*.jar', dir: 'libs') compile 'com.android.support:appcompat-v7:23.2.0' compile 'com.android.support:cardview-v7:23.2.0' compile 'com.android.support:design:24.0.0-alpha1' compile "com.google.firebase:firebase-invites:9.2.0" compile "com.google.firebase:firebase-ads:9.2.0" compile 'com.google.firebase:firebase-database:9.2.0' compile 'com.google.firebase:firebase-core:9.2.0' } 

我添加了com.google.firebase:firebase-core:9.2.0行，并为所有的firebase库select相同的版本（9.2.0），问题就解决了。

Answer 16

只是干净，重试解决了我。

Answer 17

我的项目在我的build.gradle文件（1.7和1.8）中使用了具有异构Java兼容版本的外部库。 我通过使用相同版本的lib和应用程序项目来修复它。 在我的情况下，两个：

 compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } 

Answer 18

对我来说非常简单。 只需添加：

// noinspection GradleDependency，GradleCompatible实现'com.google.android.gms：play-services-auth：11.0.4'

…和魔术发生。

Answer 19

这个问题主要发生在gradle或misversioned的库中，包括从库中定义相同的类时。 展开并检查导入的外部库…

你不能有两个相同的类被导出到一个地方，或代码，因此，dexer不知道应该使用哪一个…

Answer 20

如果您有多个项目，请确保您没有多次添加依赖项，我需要排除其他项目的依赖项，如下所示：

 compile(project(':OtherProject-SDK')) { compile.exclude module: 'play-services-gcm' compile.exclude module: 'play-services-location' compile.exclude module: 'support-v4' compile.exclude module: 'okhttp' } 

Answer 21

请在build.gradle中的android中添加此块

dexOptions { preDexLibraries = false }

Answer 22

尝试通过安装:app:installDebug 。 如果它工作，那么它与Android Studio的caching相关。 我删除了我的项目中的.gradle/文件夹，它的工作原理。

Answer 23

我有同样的问题，这是由不同的谷歌分析和firebase版本造成的。 我使用了'com.google.gms:google-services:3.1.0' ，然后添加这些依赖关系：

 compile 'com.google.android.gms:play-services-gcm:10.2.6' compile 'com.google.firebase:firebase-crash:10.0.1' 

所以把firebase版本改成10.2.6就可以解决这个问题。

 compile 'com.google.android.gms:play-services-gcm:10.2.6' compile 'com.google.firebase:firebase-crash:10.2.6' 

Answer 24

如果从两个不同的来源引入代码相同的库，将导致错误。
