【问题描述】：

我在尝试从我的 Flutter 项目构建 APK 时遇到问题。 我使用 appicon.co 创建应用图标。

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.

如何解决这个问题？有人可以帮忙吗。

【参考方案1】：

我不确定，但是在构建时，您应该尝试构建 app bundle，因为它不会占用太多空间，并且会让人们更有可能获得您的应用。
