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

这些是错误

错误 1：

错误 2：

我希望任何人都可以帮助我解决这个可怕的错误

【问题讨论】：

错误：.dex文件中的方法引用数不能超过64K。在developer.android.com/tools/building/multidex.html

了解如何解决此问题

那个^以及To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties

或者，修复您的 Google Play 服务依赖项，使其不包含所有项。请参阅此页面上的第二个蓝色框。 developers.google.com/android/guides/…

multidex ***.com/questions/32407985/…

在 multidex 之前修复 Google play 服务，不过

【参考方案1】：

错误 1 ​​清楚地说明了原因。这是解决方案

查看您的应用程序的直接和传递依赖项 - 确保您在应用程序中包含的任何大型库依赖项的使用方式都超过了添加到应用程序中的代码量。一个常见的反模式是包含一个非常大的库，因为一些实用方法很有用。减少应用代码依赖通常可以帮助您避免 dex 引用限制。

使用 ProGuard 删除未使用的代码 - 为您的应用配置 ProGuard 设置以运行 ProGuard，并确保您为发布构建启用了收缩功能。启用压缩可确保您不会随 APK 一起发送未使用的代码。

也在你的 build.gradle 添加这个

defaultConfig 
// Other settings here
multiDexEnabled true

【讨论】：

只有 multiDexEnabled true 不启用 Multidex，不过

它有帮助！谢谢！！
