int result = Settings.Secure.getInt(getContentResolver(), Settings.Secure.INSTALL_NON_MARKET_APPS, 0);if (result == 0) { // show some dialog here // ... // and may be show application settings dialog manually Intent intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_SETTINGS); startActivity(intent);}
