Why am I getting a 'cannot resolve symbol' error?
<p>I cannot see why I'm getting this error?  I'm certain my Gradle file and java class are up to par. Class and gradle file posted below.  Also, I have no errors in my XML files.  </p>

<p>What I have done already:</p>

<p>File > Invalid Caches/Restart</p>

<p>Build > Clean Project</p>

<p>Build > Rebuild Project
Restart computer</p>

<p>These are the things that were suggested to do throughout the web but none of them worked.</p>

<p>SplashActivity.java</p>

<pre><code>package com.apress.gerber.currencies;

import android.support.v7.app.AppCompatActivity;

public class SplashActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
 // Letter "R" is red 
    setContentView(R.layout.activity_splash2);
