我有Android Studio Beta版。我创建了一个新项目,编译我的旧模块,但当我尝试启动应用程序时,它没有启动消息:

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

dexarchiivemergenerexception:无法合并dex

但是我不知道如何解决这个错误。我在谷歌上搜索了几个小时,但没有成功。

我的项目gradle:

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta6'
        classpath "io.realm:realm-gradle-plugin:3.7.1"
        classpath 'com.google.gms:google-services:3.1.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的应用程序gradle:

当我没有导入第二个模块(解析器)时,应用程序没有在dex上崩溃,但当模块没有导入时,应用程序无法工作。: D: D


当前回答

删除Suragch建议的.gradle对我来说还不够。此外,我必须执行一个构建>清洁项目。

注意,为了看到.gradle,你需要切换到左上角导航器中的“项目”视图:

其他回答

以上方法我都试过了,没有一个有用。最后,我找到了适合我的工作:

应用程序/ build.gradle:

android {
    defaultConfig {
       multiDexEnabled true
    }
}

如果在包含kotlin支持后出现此错误,并且其他解决方案都不起作用,请尝试更改应用模块构建的kotlin依赖项。gradle:

implementation ("org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version") {
    exclude group: 'org.jetbrains', module: 'annotations'
}

这适用于我的Android Studio 3.0 Beta 6。请参阅下面的答案以了解进一步的解释。

我也有同样的问题。我通过执行一个干净的,然后从Android Studio 3.0菜单构建项目来解决这个问题:

Build ->清洁项目 Build ->重建项目

我尝试了所有其他的解决方案,但没有一个适合我。最后,我通过编辑build.gradle使用相同的依赖版本解决了这个问题。我认为这个问题发生在添加一个库到gradle使用不同的依赖版本的支持或谷歌库。

将以下代码添加到构建gradle文件中。然后清理和重建项目。

Ps:对我来说,这是旧的解决方案,所以你应该使用更新版本 在库。

configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
    def requested = details.requested
    if (requested.group == 'com.android.support') {
        if (!requested.name.startsWith("multidex")) {
            details.useVersion '26.1.0'
        }
    } else if (requested.group == "com.google.android.gms") {
        details.useVersion '11.8.0'
        } else if (requested.group == "com.google.firebase") {
            details.useVersion '11.8.0'

      }
