Question

当我尝试从Flutter项目中构建APK时遇到了一个问题。我使用appicon.co来创建应用程序图标。

You are building a fat APK that includes binaries for android-arm, android-arm64.
If you are deploying the app to the Play Store, it's recommended to use app bundles or split the APK to reduce the APK size.
    To generate an app bundle, run:
        flutter build appbundle --target-platform android-arm,android-arm64
        Learn more on: https://developer.android.com/guide/app-bundle
    To split the APKs per ABI, run:
        flutter build apk --target-platform android-arm,android-arm64 --split-per-abi
        Learn more on:  https://developer.android.com/studio/build/configure-apk-splits#configure-abi-split

*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.

Gradle task assembleRelease failed with exit code 1

如何解决该问题？有人可以帮忙吗。

我不确定，但是在构建时应尝试构建应用程序捆绑包，因为它不会占用太多空间，并且会使人们更有可能获得您的应用程序。
