Vector Drawables标志在支持库上不起作用24+ [英] Vector Drawables flag doesn't work on Support Library 24+

问题描述

今天，Android Nougat似乎是已发布。因此，我比以往任何时候都更兴奋地为分屏等新功能优化我的应用程序。我想推送针对SDK版本 24 的应用程序版本，以便不通知用户我的应用程序可能无法在分屏模式下使用。但是，这样做意味着我还应该更新支持库的版本 24 。像许多其他人一样，我在更新到支持库的 23.2.0 版本时遇到了问题。但是，我遵循了此答案，它解决了我的问题。现在问题从版本 24.0.0 和支持库开始返回。在所有测试中，我都使用链接答案中所述的gradle标志：

Today, it seems as though Android Nougat was released. Thus, I am more excited than ever to optimize my app for the new features like split-screen. I would like to push a version of my app that targets SDK version 24 so that users aren't notified that my app may not work in split-screen. However, doing so means that I should also update to version 24 of the Support Library. Like many others, I experienced a problem when updating to version 23.2.0 of the Support Library. However, I followed this answer and it fixed my issue. Now the issue is returning as of version 24.0.0 and up of the Support Library. In all of my tests I am using the gradle flag described in the linked answer:

vectorDrawables.useSupportLibrary = true

同样重要的是要注意，这仅发生在Lolliop之前的设备（Kitkat及更低版本）上。棒棒糖和完美的作品。使用以下依赖项时，该标记可以正常工作：

It is also important to note that this is only happening on pre-Lolliop devices (Kitkat and below). Lollipop and up works perfectly. When using the following dependencies, the flag works fine:

compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'

但是使用这些依赖项时，我会崩溃我在使用该标志之前得到的标志：

But when using these dependencies, I get a crash similar to the one I got before using the flag:

compile 'com.android.support:support-v4:24.2.0'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'
compile 'com.android.support:cardview-v7:24.2.0'

这是崩溃的堆栈跟踪：

我完全错过了什么吗？还是这已经是一个已知问题（我在Google上找不到任何东西）？任何帮助将不胜感激。

Am I totally missing something? Or is this already a known issue (I couldn't find anything on Google)? Any help would be appreciated.

推荐答案

呃...我讨厌这种情况。您问一个问题，然后几个小时后自己回答。无论如何，似乎我使用的是过时的构建工具版本。我所要做的就是在gradle中更改一行：

Ugh... I hate it when this happens. You ask a question and then answer it yourself a few hours later. Anyways, it appears as though I was using an outdated build tools version. All I had to do was change one line in my gradle:

buildToolsVersion "24.0.1"
