当前回答

multiDexEnabled true

请尝试将此添加到您的应用程序defaultConfig{}。这帮我解决了问题

其他回答

在痛苦了两个小时后找到了解决办法。

文件路径:android/build.gradle

为我工作

defaultConfig {
    applicationId "com.something"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"
    multiDexEnabled true --> This works for me
}

如果您的minSdkVersion设置为21或更高,则multidex默认启用,您不需要multidex支持库。-参考:https://developer.android.com/studio/build/multidex#mdex-gradle

修改应用程序或模块的build.gradle

android {
    defaultConfig {
        ...
        minSdkVersion 21 <----- *here
        targetSdkVersion 26
        multiDexEnabled true <------ *here
    }
    ...
}

根据官方文件

Multidex support for Android 5.0 and higher Android 5.0 (API level 21) and higher uses a runtime called ART which natively supports loading multiple DEX files from APK files. ART performs pre-compilation at app install time which scans for classesN.dex files and compiles them into a single .oat file for execution by the Android device. Therefore, if your minSdkVersion is 21 or higher, you do not need the multidex support library. For more information on the Android 5.0 runtime, read ART and Dalvik.

当你使用依赖时,你的方法增加了! 谷歌有一个解。叫做Multidex!

注意:确保最小SDK大于14。

在你的构建中。gradle:

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}



  dependencies {
      implementation 'com.android.support:multidex:1.0.3'
    }

对于androidX使用:

 def multidex_version = "2.0.1"
 implementation 'androidx.multidex:multidex:$multidex_version'

欲了解更多信息,请访问原文链接:

https://developer.android.com/studio/build/multidex

Goto构建。Gradle的应用程序文件夹, 设置minSdkVersion为21

保存并运行您的应用程序,它应该没有dex错误现在运行

该错误是由你的应用程序Gradle文件中类依赖的数量引起的。如果类超过72,400个,您可能希望使用multidex作为更好地处理文件索引的解决方案。更多信息请访问:https://developer.android.com/studio/build/multidex
