在我的项目中包含播放服务和 firebase 库后，我正在处理我的 android 应用程序，我收到此错误并且无法运行我的代码

:app:prePackageMarkerForDebug :app:transformClassesWithDexForDebug To run dex in process, the Gradle daemon needs a larger heap. It currently has approximately 910 MB. For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB. To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html Error:The number of method references in a .dex file cannot exceed 64K.

将堆大小增加到 2048M 之后。 Gradle 给出这个错误

Error:Execution failed for task ':app:transformClassesWithDexForDebug'. com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536

我按照 android 开发者网站上给出的所有说明进行操作，但仍然遇到这个问题。如何解决这个问题？

最佳答案

您需要在 android 默认配置中启用 multidex 然后:

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        applicationId "com.example.case"
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 43
        versionName "4.0.13"

        // Enabling multidex support.
        multiDexEnabled true
    }

当您在日常生活中构建应用程序时，通常会使用 debug 默认风格。因此，如果您的应用程序有超过 65k 的方法，则需要在所有类型上都启用它。

附带说明一下，您可能希望在调试版本上使用 Proguard，这样您就不必在其上启用 multiDex。

完整的 app/build.gradle ( documentation )

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

    defaultConfig {
        ...
        minSdkVersion 14
        targetSdkVersion 21
        ...

        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

最后一部分:在 list 中添加 MultiDex 应用程序(或作为您自己的 Application

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.multidex.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

关于android - .dex文件中方法引用数超过64K，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/37430331/
