Reload activity in Android

Question

Is it a good practice to reload an Activity in Android?

What would be the best way to do it? this.finish and then this.startActivity with the activity Intent?

Answer 1

Android includes a process management system which handles the creation and destruction of activities which largely negates any benefit you'd see from manually restarting an activity. You can see more information about it at Application Fundamentals

What is good practice though is to ensure that your onPause and onStop methods release any resources which you don't need to hold on to and use onLowMemory to reduce your activities needs to the absolute minimum.

Answer 2

In an activity you can call recreate() to "recreate" the activity (API 11+)
