How to Replace Deprecated startActivityForResult in Android with New API?

As Android development evolves, so do its APIs. One notable change is the deprecation of the startActivityForResult method, which many developers have relied upon for starting an activity and receiving a result. With the advent of Android 12, Google recommends using the new Activity Result API. In this guide, we'll guide you through replacing the deprecated startActivityForResult with the new API to stay up-to-date with the latest Android development practices.

Why is startActivityForResult Deprecated?

The startActivityForResult method was a staple in Android development for launching activities and receiving results. However, it has some limitations, such as tight coupling between the components and difficulties in managing the request codes. To provide a more robust solution, the Activity Result API was introduced, offering a more flexible and type-safe way to handle results.

Introducing the Activity Result API

The Activity Result API was introduced in AndroidX, designed to simplify the process of starting activities and handling their results. This new approach is more modular and offers improved separation of concerns.

Here's how you can implement the new API:

Step-by-Step Guide to Using Activity Result API

Add Dependencies:
Ensure you have the necessary dependencies in your build.gradle file:

Enhanced Flexibility

The new API enhances flexibility by enabling you to define the contracts and the callbacks independently, allowing better separation of concerns and easier management of different types of results.

Conclusion

Migrating to the new Activity Result API is crucial for maintaining your Android applications' compatibility and leveraging the latest development practices. With the deprecation of startActivityForResult, adopting the Activity Result API ensures your app remains robust, maintainable, and in line with modern Android development standards.

Updating your code might seem daunting initially, but the improved clarity and modularity offered by the new API will pay off in the long run. By following the steps above, you can efficiently replace the deprecated startActivityForResult with the newly recommended Activity Result API.
