即使在启用multidex后，也无法在Android Studio 3.0.1中合并DEX

我的android项目有问题。我最近从较低版本升级，然后用Linux重新启动我的操作系统。我的项目工作正常。但是，现在正如我编译的那样，它显示无法合并dex。我尝试过：启用;构建gradle中的apply plugin: 'com.android.application' android { compileSdkVersion 26 defaultConfig { applicationId "com.techniary.nepaltoday" minSdkVersion 19 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support:design:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.0.2' implementation 'com.google.firebase:firebase-auth:11.0.4' implementation 'com.android.support:support-v4:26.1.0' implementation 'com.google.firebase:firebase-storage:11.0.4' implementation 'com.google.firebase:firebase-database:11.0.4' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' compile 'de.hdodenhof:circleimageview:2.2.0' compile 'com.theartofdev.edmodo:android-image-cropper:2.6.+' compile 'com.squareup.picasso:picasso:2.5.2' compile 'id.zelory:compressor:2.1.0' implementation 'com.firebaseui:firebase-ui-database:2.3.0' compile 'com.squareup.okhttp:okhttp:2.4.0' implementation files('libs/YouTubeAndroidPlayerApi.jar') } apply plugin: 'com.google.gms.google-services' 选项，并尽一切可能。所以，这是我运行堆栈跟踪后的控制台日志，我还是无法弄清楚，出了什么问题。有人能帮帮我吗？ 任何帮助将非常感激。我已经发布了我的app build gradle和下面的错误

这不是一个多指标问题......它是一个依赖合并冲突问题。

通过它的外观，您的一个依赖项对CoordinatorLayout具有子依赖性，但指定了与您正在使用的版本不同的版本。您可以使用resolutionStrategy中的build.gradle来修复此问题，以定义要使用的支持库的版本。

首先创建一个变量来定义支持库版本：

ext {
    supportLibVersion = "26.1.0"
}

然后更新你的依赖关系以使用这个变量而不是硬编码值（注意双引号）：

implementation "com.android.support:appcompat-v7:${supportLibVersion}"
implementation "com.android.support:design:${supportLibVersion}"

然后，您可以向resolutionStrategy添加build.gradle：

configurations.all {
    resolutionStrategy.eachDependency { details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "${supportLibVersion}"
            }
        }
    }
}

这样做是要求Gradle忽略使用依赖项指定的版本号并使用您的版本。

如果您的multidex已启用但仍会导致问题。您可以尝试更改firebase的版本。试试11.8.0，如果它不起作用。试试12.0.0。尝试删除不必要的依赖项。

添加 implementation 'com.android.support:multidex:1.0.0' 也可以解决你的问题
