Answer 1

对于发布版本，您应该尝试用ProGuard来修复这个问题。对于调试，您可以尝试通过从主dex文件中排除一些类来修复它。

将此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/中找到gradle想要添加到main dex的类。例如，您可以排除未使用的模型或其他东西，基本上排除应用程序类启动时不需要的所有东西。不要忘记检查您在API19或更低版本上没有损坏任何东西

@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
    }
}

此外，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。

这个答案有更多关于问题的细节--main-dex-list中的类太多，main dex容量超过
