Support library VectorDrawable Resources$NotFoundException

Question

I am using Design Support Library version 23.4.0. I have enabled the gradle flag:

defaultConfig {
    vectorDrawables.useSupportLibrary = tr         


        

Answer 1

It took 3 separate things for me to get this to work using support library 23.4.0:

1. Add this to build.gradle

   defaultConfig {
       vectorDrawables.useSupportLibrary = true
   }
   

2. Add the following to onCreate of your Application class

   AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
   

   (From the reference of this link - "https://stackoverflow.com/a/45582033/10752962")

   In API less then 21,use this line before setContentView();

3. For all XML views in which you are setting a vector drawable replace

   android:src
   

   with

   app:srcCompat
   

   and in the code replace this:

   imageView.setImageResource(...);
   

   with

   imageView.setImageDrawable(...);
   

Answer 2

Support for vector drawables in places like android:drawableLeft was disabled in support library 23.3. It was announced on Google+:

we’ve decided to remove the functionality which let you use vector drawables from resources on pre-Lollipop devices due to issues found in the implementation in version 23.2.0/23.2.1. Using app:srcCompat and setImageResource() continues to work.

• https://code.google.com/p/android/issues/detail?id=204708

However, if you can live with those issues, in 23.4 you can re-enable this functionality using AppCompatDelegate.setCompatVectorFromResourcesEnabled().

If you're curious how this works, the best person to learn from is Chris Banes, who authored this functionality. He explains in detail on his blog.
