symbol not found Android React Native

Question

So I'm using this package to try and integrate MapBox into a React-Native project I'm working on, and I keep getting this error when I run it. I've followed the instructions on their page and I'm still getting this, so I assume I forgot to install a package or something along the way. Anyone know how to fix this?

a:17: error: cannot find symbol
protected List getPackages() {

/Github/ReactApp/android/app/src/main/java/com/reactapp/MainActivity.java:17: error: cannot find symbol

EDIT: Here's the source code for MainActivity:

package com.reactapp;

import com.facebook.react.ReactActivity;
import com.oblador.vectoricons.VectorIconsPackage;
import com.mapbox.reactnativemapboxgl.ReactNativeMapboxGLPackage;

public class MainActivity extends ReactActivity {

    /**
     * Returns the name of the main component registered from JavaScript.
     * This is used to schedule rendering of the component.
     */
    @Override
    protected String getMainComponentName() {
        return "ReactApp";
    }
    @Override
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
      new MainReactPackage(),
      new ReactNativeMapboxGLPackage());  // <-- Register package here
  }
}

Can you include the source of your MainActivity.java file? Looks like a bunch of missing imports. — DataDino, Sep 07 '16 at 23:56
I've updated it to include the source code from MainActivity.java — ESensei, Sep 08 '16 at 04:46
Ok you're definitely missing imports. At least these two: `import java.util.List;import java.util.Arrays;` — DataDino, Sep 08 '16 at 04:52

You are missing some imports:

 import java.util.List;
 import java.util.Arrays;
 import com.facebook.react.shell.MainReactPackage;
 import com.facebook.react.ReactPackage;

Also one of your @Overrides is on a method (getPackages) that doesn't override anything from the super class. Remove it.
