Android Question

Vector Drawables flag doesn't work on Support Library 24+

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


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'


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'


Here is the stack trace of the crash:

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

Answer

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 Anyways, it appears as though I was using an outdated build tools version.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"
