Exception from LayerDrawable

Question

I've an android app that using android support library version 23.2.1 and everything is working fine. However, I've updated the android support library version to 25.2.0 yesterday and realize some of the user are getting this exception (through Fabric crashlytics) but I couldn't reproduce it.

Here is the crash log:

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'android.graphics.drawable.Drawable android.graphics.drawable.Drawable$ConstantState.newDrawable(android.content.res.Resources)' on a null object reference

It seems to do with menu view. The layout for menu option is:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".tablet.ui.navimenu.ContainerActivity">

    <item
        android:id="@+id/memo_fragment"
        android:icon="@drawable/ic_class_white_24dp"
        android:orderInCategory="100"
        android:title="@string/memo_fragment"
        app:showAsAction="always" />

    <item
        android:id="@+id/notification_fragment"
        android:icon="@drawable/layerlist_menu_notification"
        android:orderInCategory="200"
        android:title="@string/notification_fragment"
        app:showAsAction="always" />

</menu>

layerlist_menu_notification layout is an icon with a badge:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/ic_notification"
        android:drawable="@drawable/ic_notifications_white_24dp"
        android:gravity="center" />

    <!-- set a place holder Drawable so android:drawable isn't null -->
    <item
        android:id="@+id/ic_badge"
        android:drawable="@drawable/ic_notifications_white_24dp" />
</layer-list>

Any idea where goes wrong?

@rafsanahmad007 yes, I've update the post with my layout code and yes, I'm using vector drawables. — Bryanleesh, Apr 17 '17 at 07:44

Try Change the following in build.gradle

 compileSdkVersion 25
buildToolsVersion "25.0.2"
compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:design:25.1.0'
compile 'com.android.support:support-v4:25.1.0'

Is't a bug in `25.2.0`? – Bryanleesh Apr 17 '17 at 07:47
