</android.support.constraint.ConstraintLayout>  

2.MainActivity.java:

package example.akash.com.screenorientation;  

  

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 button1;  

    @Override  

    protected void onCreate(Bundle savedInstanceState) {  

        super.onCreate(savedInstanceState);  

        setContentView(R.layout.activity_main);  

  

        button1=(Button)findViewById(R.id.button1);  

    }  

    public void onClick(View v) {  

        Intent intent = new Intent(MainActivity.this,SecondActivity.class);  

        startActivity(intent);  

    }  

}  

3.activity_second.xml:

<?xml version="1.0" encoding="utf-8"?>  

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"  

    xmlns:app="http://schemas.android.com/apk/res-auto"

</android.support.constraint.ConstraintLayout>  

4.SecondActivity class:

package example.akash.com.screenorientation;  

  

import android.support.v7.app.AppCompatActivity;  

import android.os.Bundle;  

  

public class SecondActivity extends AppCompatActivity {  

  

    @Override  

    protected void onCreate(Bundle savedInstanceState) {
