right, becuase you didnt send any data

check if the gotBasket is NULL before assigning

like this:

Bundle gotBasket = getIntent().getExtras();
if(gotBasket != null){
    gotPassenger= gotBasket.getString("passenger");
    gotStaffNumber= gotBasket.getString("clientcode");
    etPassenger.setText(""+ gotPassenger );
    etStaffNumber.setText("" + gotStaffNumber);
}

Instead of:

Bundle gotBasket = getIntent().getExtras();

better use this:

if(getIntent().hasExtras("passenger")){
//get Extras here
}

That way, you wont get NPE as you only try to get the Bundle Extras only if they were passed
