DexOverflowException：主dex文件无法容纳请求的类

DexOverflowException：主dex文件无法容纳请求的类

我是一个有用的助手，可以帮您进行文本翻译。

我有一个相当大的、多模块、多口味的多dex项目，但最近在尝试执行命令行构建（assemble{flavor}Release）时出现了错误。

错误信息为:

DexOverflowException: Cannot fit requested classes in the main-dex file

以下是 --debug 构建的更多日志：

如何控制主dex文件中包含的内容？如何强制主dex文件包含更少的方法？

我的设置：

compileSdkVersion 27
buildToolsVersion '27.0.3'

gradlew:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.5-all.zip
plugin: classpath 'com.android.tools.build:gradle:3.2.0-alpha04'

请在你的 build.gradle 文件中添加 multiDex，参考此帖子。 - Yusuf Adefolahan

我尝试了Alexander Bratusenko的答案，但没有帮助，不过这是一个很好的线索。真正有用的是，我将gradle插件降级到

classpath 'com.android.tools.build:gradle:3.1.4'

- Bartosz Kraszewski

当主dex文件的限制超出时，确认此解决方案有效。 - clearpath

禁用保留运行时注释类可能会有所帮助。只需将其放置在每个模块 gradle 文件的 android{} 部分即可。

dexOptions {
        preDexLibraries = false
        keepRuntimeAnnotatedClasses false
    }

通常这种情况发生在项目中大量使用dagger2的时候。

这里实际上发生的是您正在越过 dex 方法计数 65536 (这意味着您在 apk 中只能使用 65536 个方法)，而您只超出了 12 个方法

DexOverflowException: 无法将请求的类放入主 dex 文件中 (# methods: 65548 > 65536)

最好的建议是您应该真正减少方法计数。

删除未使用的库
如果您仅使用库的一部分，请尝试定义自己的方法并实现它。

此链接将有助于观察您的 dex 方法计数。

但是，如果您确实需要使用超过 65536 的 dex 方法计数，您应该查看启用 multidex

愉快的编码！

谢谢回复，不幸的是我已经启用了MultiDex - 问题是单个dex文件没有达到限制 - 在我的情况下，主dex文件超过了限制 - 其中之一。 - Bartosz Kraszewski

对于发布版本，您应该尝试使用proguard来解决这个问题。对于调试版本，可以尝试通过从主dex文件中排除一些类来解决它。

将以下内容添加到应用程序模块：

   import your.awesome.app.MainDexGenerator

   tasks.whenTaskAdded {
            if (it.name.contains('transformDexArchiveWithDexMergerFor') && it.name.contains('Debug')) {
                it.doFirst(new MainDexGenerator([
                        'io/reactivex/annotations',
                        'kotlin',
                        'com/fasterxml'
                        //....and other you think could work 
                ]))
            }
        }

您可以在intermeditates/legacy_multidex_main_dex_list/路径下找到Gradle要添加到主dex的类。例如，您可以在应用程序启动时排除未使用的模块或其他基本上您不需要的内容。不要忘记检查您没有破坏API19或更低版本的任何东西。

使用groovy插件在build.gradle中设置buildSrc。

在buildSrc/main/groovy/your/awesome/app中添加您的操作。

@CompileStatic
class MainDexGenerator implements Action<Task> {

    private static final String MAIN_DEX_FILE = 'mainDexList.txt'

    // list we want to exclude frome MainDex
    private List<String> excludedList
    MainDexGenerator(List<String> excludedPackages) {
        excludedList = excludedPackages;
    }

    @Override
    void execute(Task task) {
        for (File inputFile : task.inputs.files.files) {
            if (inputFile.absolutePath.endsWith(MAIN_DEX_FILE)) {
                List<String> result = Files.lines(inputFile.toPath())
                        .filter { isNotMatch(it) }
                        .collect(Collectors.toList())
                Files.write(inputFile.toPath(), result, WRITE, TRUNCATE_EXISTING)
                break
            }
        }
    }

    private boolean isNotMatch(String line) {
        for (String item : excludedList) {
            if (line.contains(item)) {
                return false
            }
        }
        return true
    }
}

要查看方法数，您可以使用apkAnalyzer工具。查找第一个dex。

您还可以尝试重构代码并从应用程序类中提取一些职责。

您也可以尝试将minApi增加到21。
