How to extend UnityPlayerActivity

I am trying to extend the UnityPlayerActivity. I am using android studio 3.2.1. I copied the classes.jar from unity into the libs folder in my android studio project. I have added it as a library. The problem right now is when I open my app it immediately closes. I think maybe something is wrong with my gradle but I have no idea how to fix it. It might also be the name of the package. I'm not sure if they need to be the same but my android project currently has a different package name than my unity project. I've never extended the UnityPlayerActivity before so I'm sure I'm missing something simple.

Here is my gradle:

 apply plugin: 'com.android.library'

 android {
 compileSdkVersion 27

 defaultConfig {
     minSdkVersion 16
     targetSdkVersion 27
     versionCode 1
     versionName "1.0"
     testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
 }
 buildTypes {
     release {
         minifyEnabled false
         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
     }
 }

 lintOptions { abortOnError false }
 }

 dependencies {
   implementation fileTree(include: ['*.jar'], dir: 'libs')
   testImplementation 'junit:junit:4.12'
   androidTestImplementation 'com.android.support.test:runner:1.0.2'
   androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
   implementation files('libs/classes.jar')
 }

 task deleteOldJar(type: Delete) { delete 'libs/LRA2n1Activity.jar' }
 task exportJar(type: Copy) { from('build/intermediates/intermediate- 
 jars/release/') into('libs/') include('classes.jar')
 rename('classes.jar', 'LRA2n1Activity.jar') }

Here is my manifest:

   <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="com.Immersion.LRA2n1"

Any and all help will be greatly appreciated.
