Android Studio 4 incorrect vector drawable preview

Question

After update to Android Studio 4.0, all my vector icons display wrong on the preview screen. But they look normal after running an application on the device. It concerns all

Answer 1

In your build.gradle file

android { 
          defaultConfig
                      {
                           vectorDrawables.useSupportLibrary = true 
                      }
        }

dependencies {  
             compile 'com.android.support:appcompat-v7:23.2.0' 
             }

and use app:srcCompat instead of android:src

Invalid Caches/Restart

then try to create a new drawable vector its should works..

Answer 2

I fixed it by disabling Settings -> Experimental -> Use new Layout Rendering Engine.

Answer 3

This is probably because you have a non-default locale (to check run locale in terminal). In particular LC_NUMERIC. If that's the case, to fix the issue run the studio with e.g. LC_NUMERIC="en_US.UTF-8".
