降级 android 支持库，构建 mozilla fennec

Question

我正在尝试为 Android 构建 Firefox。我遵循了这里的所有说明：https://wiki.mozilla.org/Mobile/Fennec/Android#Android_NDK_and_SDK_version_notes

I 运行 ./mach Build，终端显示如下错误：

现在，我认为问题的出现是因为 Android 构建 SDK 和支持库版本不同。但是我无法将我的支持库降级到早期版本。谁能建议我这样做的方法？

Answer 1

正如 MDN page (see the "2015/08/26 "Support library 23 and SDK 22/23" note), here's 邮件列表中关于如何降级库的交流所报道的那样。

简而言之，下载 this zip 并将其解压到 $ANDROID_HOME/extras/android/ 中。我建议先进行备份。
