Intent intent = new Intent(this, SecondActivity.class);
intent.putExtra("name", "Call By Explicit Intent.");
startActivity(intent);

Steps to use Explicit Intent in your project.

1. Crate a project in android studio.
2.  Open your main_activity.xml and update it-
   

   <?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:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context="com.pankaj.explicitintent.demo.MainActivity">
   
       <Button
           android:layout_width="match_parent"
           android:text="Explicit Intent"
           android:onClick="openSecondActivity"
           android:layout_height="wrap_content" />
   
   </RelativeLayout>
   

     
   
3. Open your MainActivity.JAVA class and update it for change text at run time-
   
   

   package com.pankaj.explicitintent.demo;
   
   import android.content.Intent;
   import android.os.Bundle;
   import android.support.v7.app.AppCompatActivity;
   import android.view.View;
   
   public class MainActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
       }
   
       //___________methode will be call when click on "Explicit Intent"
       public void openSecondActivity(View view) {
   
           //__________create intent to open SecondActivity.
           Intent intent = new Intent(this, SecondActivity.class);
   
           //__________put some data for sending to second activity.
           intent.putExtra("name", "Call By Explicit Intent.");
   
           //____________call to start the second activity.
           startActivity(intent);
       }
   }
   
   

   
   
4. Create an activity(MainActivity.java) which will be open by explicit intent. Open your MainActivity.java and update it-
   
   
   

   package com.pankaj.explicitintent.demo;
   
   import android.os.Bundle;
   import android.support.v7.app.AppCompatActivity;
   import android.widget.Toast;
   
   public class SecondActivity extends AppCompatActivity {
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_second);
   
           //____________get data which is sent from mainactivity by intent
           String name = getIntent().getStringExtra("name");
   
           //____________Show this data into the toast.
           Toast.makeText(this, name, Toast.LENGTH_SHORT).show();
       }
   }
   

   
   
5. Open your activity_second.xml and update it-
   
   
   

   <?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:layout_width="match_parent"
       android:layout_height="match_parent"
       tools:context="com.pankaj.explicitintent.demo.SecondActivity">
   
       <TextView
           android:layout_centerInParent="true"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="second activity" />
   
   </RelativeLayout>
   
   

   
   
    
6. Now all the development process for Explicit Intent has completed, Please run the application.
   
   
   
   
    
7. Click on "Explicit Intent".
