question

Here is an example:

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        CustomerMode.enable(this); // This is turning on Customer Mode


        // Below is checking if CustomerMode is on Primary Display
        // Please note that the CustomerMode SDK only works on Primary Display
        if (CustomerMode.isShownOnPrimaryDisplay(this) == true) {
            System.out.println("On Primary Display!!");
            Intent intent = new Intent("clover.intent.action.CUSTOMER_MODE");
            CustomerMode.getStateFromIntent(intent);
            CustomerMode.getState(this);
            System.out.println(intent);
            System.out.println("Customer Mode State " + CustomerMode.getState(this));
        } else {
            System.out.println("Not on Primary Display!!");
            finish();
        }
    }


    @Override
    protected void onStart() {
        super.onStart();
        // The lines below are the confirmation of the state of CustomerMode.
        // If CustomerMode is DISABLED it will show you the state and
        // will system print out a note to turn on CustomerMode
        if (CustomerMode.getState(this) == State.DISABLED) {
            CustomerMode.getState(this).toString();
            System.out.println("The State is:" + CustomerMode.getState(this) + " please enable the Customer mode");
            CustomerMode.enable(this);
        } else {
            System.out.println("Customer Mode is successfully enabled");
        }
    }


    // Below is where you can add your own code integration to exit CustomerMode.
    // This is just an example, although, it doesn't do anything for now
    @Override
    public void finish() {
        if (CustomerMode.getState(this) == CustomerMode.State.ENABLED) {
            CustomerMode.disable(this, true);
        }
        super.finish();
    }
}
