java.lang.NoSuchMethodError: No static method setFactory2(Landroid/view/LayoutInflater;Landroid/view/LayoutInflater$Factory2;)

Ok this is very weird. I'm suddenly getting this crash in my logcat when I run the app in the emulator, when before I've never had it, and I've not made any changes to my app since the last time I ran it in the emulator a few weeks ago and it was working.

Here's the full error:

java.lang.NoSuchMethodError: No static method setFactory2(Landroid/view/LayoutInflater;Landroid/view/LayoutInflater$Factory2;)V in class Landroid/support/v4/view/LayoutInflaterCompat; or its super classes (declaration of 'android.support.v4.view.LayoutInflaterCompat' appears in /data/app/com.pa.myapp-2/base.apk)

I tried Google searching but can't find this crash error anywhere else. I tried reinstalling Android Studio but it didn't help. Some "similar" errors I've found on stackoverflow says it may be related to appcompat version, but I've tried different versions with no luck. Here's my gradle compiles:

}

The logcat error says this line is to blame in my SplashActivity.java file, but I haven't modified this java file at all since I originally created the app 2 years ago.

super.onCreate(savedInstanceState);
