Error inflating layout of FloatingActionButton : NoSuchMethodException

So I'm getting an error inflating the layout, something about NoSuchMethodException. I've looked at other solutions to this and I've made sure that I've done the following, which I have, and I'm still getting the exception. Does anyone know what could be causing this??! I am completely lost, everything was working fine and then I updated my android studio and now I'm getting this error.

My activity is an AppCompatActivity

My app layout, using AppCompat:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="windowNoTitle">true</item>
</style>


My layout code, using app namespace for setting the background tint:

<android.support.design.widget.FloatingActionButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@drawable/ic_add_white_18dp"
app:backgroundTint="@color/colorPrimary"
app:layout_behavior="Behaviors.ScrollAwareFABBehavior"/>

<include layout="@layout/content_main" />


This is my gradle build file:

compile 'com.android.support:multidex:1.0.0'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.google.android.gms:play-services:9.4.0'


Here is my stack trace:

Answer

I have exactly the some problem, it was random and it was today after mindlesly selecting "ok" on Android studio about something related to downloading stuff. :P

I tried to upgrate SDK build tools (without using them), and rebuilted the project but no luck.

Then, i upgraded to JAVA 1.8, moved to compileSdkVersion 24 and support library 24.2.1 and it worked.

So chances are that Google broke something on last update.
