Intent back to previous activity crashing

caused by a string object is reading as null which is initialized.

    public String lastAction = "";

in onCreate

lastAction = model.lastAction;

it's working perfectly on the first onCreate, but when we go to the second activity and that lastAction object is null when back to previous activity using intent.

Just do operation 

if(lastAction!=null){
//do all stuff here 
}

OR

pass your object through onBackPress() method of second-activity.

OR

Save your object into sharefrefernce and get it when onCreate() when Activity called and onRestart() when activity will come out from stack.
