Android: getting Resources$NotFoundException for abc_ic_ab_back_material

Question

I\'m getting a Resources$notfoundexception on older (pre-L) devices. I\'m including the full stacktrace below.

My version of the support library is the latest (24.1

Answer 1

Instead of:

ContextCompat.getdrawable()

Try using:

AppCompatDrawableManager.get().getDrawable() 

Answer 2

Another solution,
in addition to AppCompatDelegate.setCompatVectorFromResourcesEnabled(true)
is to wrap your vector drawable into another drawable:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_your_vector"/>
</selector>

Might be useful when you use as a drawable for a TextView (i.e. DrawableLeft)

Answer 3

Accepted answer is not covered all cases. It will not work on Android 4.0.3/4.1.1/4.1.2 platform with 25.x.x support library. The right way to fix problem with abc_ic_ab_back_material.xml is to override homeAsUpIndicator attribute in your theme. For example, my theme is inherited from Theme.AppCompat.Light.NoActionBar. As for value of mentioned attribute, you can use @drawable/abc_ic_ab_back_mtrl_am_alpha or your custom 'back' drawable.

Answer 4

Please make sure you are using AppCompatActivity instead Activity. If you're using AppCompat's theme, then you also need to use it's Activity.

Answer 5

private resources its treated differently at compile time and runtime..to fix I usually take the offending private resource and backport it to my app in my res files

Answer 6

The answer to this turned out to be buried at the bottom of this guide:

It turns out that all you need to add this line in at the beginning of the activity that will use the resource:

static {
        AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
    }
