Androidx 迁移获取 DexArchiveMergerException：无法合并 dex

Question

我已经迁移到 androidx，并且在使用它很长时间后，我无法摆脱下面的错误。我已经集成 multidex 但我仍然收到错误。

这是例外情况：

FAILURE: Build failed with an exception.

出了什么问题：

Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForBetaDebug'. java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我做不到。这是我的 build.gradle。有什么想法吗？

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {

    }

Answer 1

很难看出问题出在哪里。尝试以下操作之一：

1- 将 google 服务更新到最新版本

2-强制所有使用旧支持库的外部库使用相同版本，在依赖项之前添加：

configurations.all {
    resolutionStrategy {
        eachDependency { DependencyResolveDetails details ->
            if (details.requested.group == 'com.android.support' && details.requested.name != 'multidex') {
                details.useVersion "VERSION_HERE" // try 28.0.0
            }
        }
    }
}

dependencies {
    ...
}

这将使 gradle 更容易将所有支持库类替换为 androidx 类

3-"buildToolsVersion"不再需要，gradle会为您选择正确的版本，您需要这个特定版本吗？

4- 我停止使用 Fabric，因为它由于内部依赖性导致我的应用程序出现很多编译问题。如果可能，请尝试将其删除。

Answer 2

包中应该没有com.android.support。最好在 gradle.properties 文件中启用 Jetifier，而不是修复过时的库，甚至不应该包含这些库：

android.enableJetifier=true
android.useAndroidX=true
