android - AAPT2 编译失败 : invalid dimen on Android 3. 0 Canary 1

Question

我正在玩适用于 Android 的 Instant Apps。我安装了所有正确的软件包，并且厌倦了创建具有 Instant App 支持的新应用程序(在创建新应用程序时选中 Instant App 框)。问题是我总是遇到编译工具的问题。有没有其他人有这个问题并且能够找到任何解决方法。

我的环境:

Android Studio 3.0 Canary 1

编译SDK:25

构建工具:“26.0.0 rc2”

Gradle 插件:3.0.0-alpha1

Gradle:尝试了 gradle-4.0-milestone1 和 2

Java 1.8/1.7

操作系统:尝试了 Windows 10 和 Linux Ubuntu 16.4 LTS

错误:

有问题的行包含 (520):

<item format="float" name="abc_disabled_alpha_material_dark" type="dimen">0.30</item>
