Going to home screen programmatically

Question

I want to go to the home screen programmatically in Android when the user clicks on button. How can this be done?

Answer 1

You can do this through an Intent.

Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);

This Intent will start the launcher application that the user has defined. Be careful with this because this will look like your application crashed if the user does not expect this.
