您可能已经知道，从2019年8月1日开始，所有Android版本必须符合Google Play 64位要求。 Kivy + Buildozer允许我们创建此类应用吗？
提前谢谢！

在评论中，here's在Kivy存储库中有一个未解决的问题，涉及Kivy支持Google即将推出的64位二进制要求的计划。这是其中一位开发人员的评论：
在https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html中：
2019年8月，Play将要求具有本机库的新应用程序和应用程序更新除了提供32位版本外，还必须提供64位版本。
我认为我们应该默认使用arm64-v8a以防止以后出现问题，并开始考虑如何进行多个目标编译并将其嵌入一个APK中。
...它有三个竖起大拇指。
答案 1 :(得分：1)
Buildozer已经允许您创建这样的应用程序，只需将buildozer.spec中的android.arch配置令牌更改为arm64-v8a，而不是默认的armeabi-v7a。
我们不支持将多种架构捆绑在一起的APK，主要是因为所有已编译的组件都会大大增加APK的大小，但是您可以将每种类型的一个APK上传到Google Play。
我们可能会在接下来的几个月内更新默认值，并提供有关它的更多文档。

很简单，只需转到 import java.io.*;

文件中的第 232 行并将 buildozer.spec 更改为 arch，然后构建应用程序，然后通过更改 {{1 arm64-v8a 文件的 }} 到 arch。在 Google Play 控制台上，上传这两个文件。
