Android: Crash when using vector Drawables on Pre Lollipop.

First of all, we need to know one thing that

For AppCompat users, 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 [https://goo.gl/u5suZB, https://goo.gl/fW5Tyd]. Using app:srcCompat and setImageResource() continues to work.

Second, Happy to advertise that They re-enabled that VectorDrawable in Android Support Library 23.4.0

For AppCompat users, we’ve added an opt-in API to re-enable support Vector Drawables from resources (the behavior found in 23.2) via AppCompatDelegate.setCompatVectorFromResourcesEnabled(true) — keep in mind that this still can cause issues with memory usage and problems updating Configuration instances, hence why it is disabled by default. If you want re-enable this, just stick this at the top of your Activity:

Finally, what thing we need to do

static {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

Still need

I’m guessing that most of you will be using Gradle so let’s quickly walk through that. If you’re using v2.0 or above of the Gradle plugin, we have a handy shortcut to enable everything:

android {
  defaultConfig {
    vectorDrawables.useSupportLibrary = true
  }
}

If you have not updated yet, and are using v1.5.0 or below of the Gradle plugin, you need to add the following to your app’s build.gradle:

android {
  defaultConfig {
    // Stops the Gradle plugin’s automatic rasterization of vectors
    generatedDensities = []
  }
// Flag to tell aapt to keep the attribute ids around
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
}

If you want to do something in your code

Drawable drawable = AppCompatResources.getDrawable(getContext(), R.drawable.your_vector_drawable);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
    textView.setCompoundDrawablesRelativeWithIntrinsicBounds(drawable, null, null, null);
}
