How to Send Data Between Activities in Android Studio

As an Android developer, I frequently deal with the challenge of sending data between activities and operations. Smooth and intuitive user experience creation requires the capacity to communicate data fluidly, whether it be user input, preferences, or information collected from an API. I'll lead you through the process of passing data across activities in Android Studio in this tutorial, giving my personal experience-based insights and emphasizing best practices as we go.

Sending data from one activity to another in android studio

1: Define Intent

// Define Intent to start target activity
Intent intent = new Intent(this, TargetActivity.class);

2: Add Data to Intent

// Add data to Intent using putExtra() method
intent.putExtra("key", data);

3: Start Target Activity

// Start target activity with Intent
startActivity(intent);

4: Retrieve Data in Target Activity

// Retrieve data from Intent in target activity
Intent intent = getIntent();
String data = intent.getStringExtra("key");

5: Using Values

// Check for null values when retrieving data
if (data == "yes") {
    // Do this
} else {
    // Do this
}

In conclusion, a key component of developing Android apps is data transmission across activities, which facilitates smooth communication and interaction between the many components of an app. You may improve the functionality and user experience of your apps by efficiently transmitting data across activities in Android Studio by following the methods described in this article.
