How to open Launcher launcher settings screen programmatically in Android using Intent

Question

I am looking for a way to open the Launcher list screen in the "Home" option in system settings using Intent.

The main system Settings → Home → List of launchers.

I need to open this Launcher list screen using Intent. If anyone could point me in the right direction, I would really appreciate it. Many thanks.

Answer 1

To open the settings page of the main screen, call the Settings.ACTION_HOME_SETTINGSintent. However, this is ONLY supported in API 21 and higher.

API 20 Settings.ACTION_SETTINGS, . ( )

, . API 21 , API 20 .

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
    final Intent intent = new Intent(Settings.ACTION_HOME_SETTINGS);
    startActivity(intent);
}
else {
    final Intent intent = new Intent(Settings.ACTION_SETTINGS);
    startActivity(intent);
}
