之前在
https://bitbucket.org/javafxports/arm/downloads 包含移动/嵌入式实验代码。我删除了该代码，现在它再次以正常速度运行。

The dalvik-sdk.zip that was previously available at https://bitbucket.org/javafxports/arm/downloads contained experimental code for mobile/embedded. I removed that code, and it works at normal speed again now.

您可以在旧位置下载新的sdk：
https://bitbucket.org/javafxports/arm/downloads/armv6hf-sdk.zip

You can download the new sdk at the old location: https://bitbucket.org/javafxports/arm/downloads/armv6hf-sdk.zip

对于这种混淆感到抱歉，我希望这可以解决这个问题吗？

Sorry about the confusion, I hope this fixes the issue?
