Updated Android Studio, now Error Inflating Class

Question

My app was working just fine. I updated Android Studio. Then I built my app again for testing and now it immediately crashes! It's like Android Studio moved around resources. I'm not sure what is causing this error. I went through the trouble of building the app from scratch AGAIN, copying and pasting the code, and I get the same error. Help from the community would be appreciated.

Here's the XML file being referenced:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">

<com.mystuff.test.BattleView
    android:id="@+id/pea"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

</LinearLayout>

Here's the referenced constructor for the view and the thread:

//constructor gets the surface holder, assigns a callback and creates an instance of the thread
public BattleView (Context context, AttributeSet attrs) {
    super(context, attrs);
    SurfaceHolder holder = getHolder();
    holder.addCallback(this);
    thread = new BattleThread(holder, context, new Handler() {
        @Override
        public void handleMessage(Message m) {
        }
    });
    setFocusable(true);
}
//method to return the thread in case you need to control it from the activity
public BattleThread getThread() {
    return thread;
}

class BattleThread extends Thread {
    public BattleThread(SurfaceHolder surfaceHolder, Context context, Handler handler) {
        mySurfaceHolder = surfaceHolder;
        myContext = context;
        backgroundImg = BitmapFactory.decodeResource(context.getResources(), R.drawable.nopeastitlecrackedstart);
        backgroundOrigW = backgroundImg.getWidth();
        backgroundOrigH = backgroundImg.getHeight();
    }

//the rest of the thread.  Code I haven't changed before it broke.
}

check if you are using the correct package name in layout for BattleView. I guess it should be ' — SubinM, Jul 03 '15 at 17:12
I did not edit that in my original post and I have since. That was my bad, but not the solution to my problem. — Adam, Jul 03 '15 at 17:21
Try to update all the SDK libraries via SDK Manager too. (And make a Clean and then a Rebuild, as @EpicPandaForce suggests) — Joaquin Iurchuk, Jul 03 '15 at 17:55
Updating all the SDK libraries and then running a clean project and then rebuilding did not work. Same error. I'll try making the Battle thread a static inner class. — Adam, Jul 03 '15 at 20:39

Thanks to everyone who took the time to read through the code and give me some advice. After much trial and error, it turned out that my canvas draw method inside the Battle Thread had become too large and was not compiling correctly. It wasn't over the method limit size so I have no idea why it was rejecting it, but through a process of elimination, that turned out to be the solution. It was frustrating that I didn't get that specific error in any of the logs and had to go find it myself.
