刚刚将我的应用迁移到androidx，无法解决此错误。我只是在npx react-native run-android执行结束时收到的，这中断了应用程序。错误看起来像这样：

我已经尝试过清理，重建，使用版本的依赖项之类的事情，但是无法克服这一点。

android {
    compileSdkVersion 28
    buildToolsVersion '28.0.3'

    defaultConfig {
        applicationId "app-name"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode 2097177
        versionName "2.0"
        multiDexEnabled true

        ndk {
            abiFilters "armeabi-v7a", "x86"
        } …
