Answer 1

you can try this, it opens setting screen

check for it

import android.provider.Settings;

int result = Settings.Secure.getInt(getContentResolver(),  Settings.Secure.INSTALL_NON_MARKET_APPS, 0); 

open settings

Intent intentSettings = new Intent();
 intentSettings.setAction(android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
 startActivity(intentSettings);
