How to manually do this?

MainActivity.Java 

 package com.sabithpkcmnr.sampleapp;  
   
 import android.content.Intent;  
 import android.support.v7.app.AppCompatActivity;  
 import android.os.Bundle;  
 import android.view.View;  
 import android.widget.Button;  
   
 public class MainActivity extends AppCompatActivity {  
   Button bt_restart;  
   @Override  
   protected void onCreate(Bundle savedInstanceState) {  
     super.onCreate(savedInstanceState);  
     setContentView(R.layout.activity_main);  
     bt_restart=(Button)findViewById(R.id.restart);  
     bt_restart.setOnClickListener(new View.OnClickListener() {  
       @Override  
       public void onClick(View v) {  
         Intent restartIntent = getBaseContext().getPackageManager()  
             .getLaunchIntentForPackage(getBaseContext().getPackageName());  
         restartIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  
         startActivity(restartIntent);  
       }  
     });  
   }  
 }  

activity_main

 <?xml version="1.0" encoding="utf-8"?>  
 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"  
   xmlns:tools="http://schemas.android.com/tools"  
   android:id="@+id/activity_main"  
   android:layout_width="match_parent"  
   android:layout_height="match_parent"  
   android:paddingBottom="@dimen/activity_vertical_margin"  
   android:paddingLeft="@dimen/activity_horizontal_margin"  
   android:paddingRight="@dimen/activity_horizontal_margin"  
   android:paddingTop="@dimen/activity_vertical_margin"  
   android:background="@android:color/white"  
   tools:context="com.sabithpkcmnr.sampleapp.MainActivity">  
   
   <Button  
     android:text="Restart This App"  
     android:layout_width="wrap_content"  
     android:layout_height="wrap_content"  
     android:id="@+id/restart"  
     android:layout_centerVertical="true"  
     android:layout_centerHorizontal="true" />  
   
 </RelativeLayout>  

We have added button named restart with id as restart in xml file

Finally, run your app there you may find your app restart when you press the restart button.
