Question

I am using Following Code to start setting I want to launch the setting activity which is started by android ins

PackageList allowedAppsPackageName=CallH         


        

Answer 1

There are many action constants in the Settings class that can be used to create an intent that will start an activity for the provided sub-Setting or simply launch the Settings app depending on the action.

For example:

intent = new Intent(Settings.ACTION_SETTINGS); // ACTION_SETTINGS will start the Settings app

intent = new Intent(Settings.ACTION_WIFI_SETTINGS); // ACTION_WIFI_SETTINGS will show the WiFi settings

Answer 2

You can use this snippet to open Settings Activity :

Intent intent=new Intent();
intent.setComponent(new ComponentName("com.android.settings", "com.android.settings.Settings"));
startActivity(intent);

If you do not know what Activity you have to open,you can find it's name and it's package name as I mentioned here.
