Support library VectorDrawable Resources$NotFoundE

Question

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

defaultConfig {
    vectorDrawables.useSupportLibrary = true
}

I am using build tools version 23.0.2, but still, I am getting Resources$NotFoundException on KitKat or lower.

It is occurring when I use android:drawableLeft or imageView.setImageResource(R.drawable.drawable_image).

And yes, I am putting this on every activity where I am using drawables

static {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

Is this a bug of the support library?

Answer 1

To complement some of the answers here: backward-compatible support for VectorDrawables comes with a price and doesn't work in all cases.

In which cases does it work? I've made this diagram to help (valid for Support Library 23.4.0 to at least 25.1.0).

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.

Links to issues:

• https://code.google.com/p/android/issues/detail?id=205236
• 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.

Answer 3

Try using:

imageView.setImageDrawable(VectorDrawableCompat.create(getResources(), drawableRes, null));

You don't have to add AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); this way.

Just inflate your vector drawables using VectorDrawableCompat and you're all set.

Answer 4

defaultConfig {
  vectorDrawables.useSupportLibrary = true
}

use this in app.gradle

Then use AppCompatDrawableManager to setDrawable and getDrawable. Works for me

Answer 5

Sorry for being late to the party but this answer may help users who want to enable the flag AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); for all activities.

1. Create a class which extends to Application (android.app.Application)

public class MyApplicationClass extends Application
{
    @Override
    public void onCreate()
    {
        super.onCreate();
    }
}

2. Head over to Manifest.xml and add the following line to your tag

<application
    android:name=".MyApplicationClass"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    ...
</application>

3. Add the following code above onCreate in MyApplicationClass.java

// This flag should be set to true to enable VectorDrawable support for API < 21
static
{
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

Complete code for MyApplicationClass.java

import android.app.Application;
import android.support.v7.app.AppCompatDelegate;

/**
* Created by Gaurav Lonkar on 23-Dec-17.
*/

public class MyApplicationClass extends Application
{
    // This flag should be set to true to enable VectorDrawable support for API < 21
    static
    {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    }

    @Override
    public void onCreate()
    {
        super.onCreate();
    }
}

Answer 6

change

imageView.setImageResource(R.drawable.drawable_image)

to

imageView.setImageDrawable(ContextCompat.getDrawable(getContext(), R.drawable.drawable_image));

if you want to use vectordrawable in xml, use this:

app:srcCompat="@drawable/drawable_image"
