what task are you on? you are getting the error because you declare the variable allDoneToast but never assign it anything. if its task 1 you need to assign your second line to the declaration on the first. you also dont need to show it yet

//this never gets assigned
Toast allDoneToast;
Toast.makeText(this, "All done!", Toast.LENGTH_LONG).show();

to fix it just assign it the second like but remove the call to show

Toast allDoneToast = Toast.makeText(this, "All done!", Toast.LENGTH_LONG);

you almost have it, you dont need to assign your third toast statement to a variable. 

Toast allDoneToast = Toast.makeText(this, "All done!", Toast.LENGTH_LONG);
allDoneToast.show();
//since you are chaining the makeText and show methods in one line, you dont need to assign it anything. 
Toast.makeText(this, ":)", Toast.LENGTH_LONG).show();
