I have tried invalidating the caches and restarting but it still shows up and will not compile and run as it used to before. I tried renaming the class file if i remember correctly and must have changed the name on something that made this how up. It also gives me the same error where findViewById, .oncreate, and setContentView. I migh have also renamed or tried to rename one of the packages because it was examplecom and it wouldnt allow me to upload it.

package com.threedeestone.mike.threedeestone;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.widget.EditText;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

import java.text.DecimalFormat;


public class MainActivity extends ActionBarActivity {

Check this blog where explains the changes on the Library.

ActionBarActivity is deprecated, you should use AppCompatActivity instead and make a clear project and try it out.

public class MainActivity extends AppCompatActivity {

If the issue still it could be that in your gradle.app you don't have added this line of code 

compile 'com.android.support:appcompat-v7:22.1.1'
