MainActivity context Android

I need to fetch the MainActivity context and call getIntent() to process the intent that started the Activity.

Due to some reasons, I don't want to do this in my MainActivity (that would have been a simple getIntent() in any non-static method of the class).

The MainActivity's instance will be exposed (somehow) and with that object, I need to invoke getIntent().

There's the following way:

public class MainActivity extends Activity {
  
  // Store the activity context
  private static Activity activityContext;

  public void onCreate() {
    activityContext = this;
  } 

  public static Activity getActivityContext () {
    return activityContext;
  }
}

But is there any other way to get the MainActivity context? Like a direct func to the Activity's instance instead of capturing the instance and exposing a method as shown above..

Solution

  • Retrieve the Intent in onCreate, pull everything you need out of it and then you can store it in a number of places.

    SharedPreferences or a Database or Static Variables or a Singleton

    When you finally need the Intent data you can pull it from a place that is more permanent, instead of an Activity which is not.
