Been debugging for a while… Help? Yes, I know what caused it, but idk how to fix it…
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Random ran = new Random();
String[] fate = {"Reese","Maak","Buscarino","Gaston","Sakuma","Namjoshi"};
int i = ran.nextInt(6);
if(i!=0){
String stuff = fate[i];
TextView t;
t =(TextView) findViewById(R.id.textView1);
CharSequence c = stuff;
t.setText(c);
}
if(i==0){
String stuff = "Reese";
TextView t;
t =(TextView) findViewById(R.id.textView1);
CharSequence c = stuff;
t.setText(c);
}
}

You’re missing actual line data, but I’d guess there is an error in your layout file (namely that you don’t have one).
Somewhere after the
super.onCreate(savedInstanceState);call you need to callsetContentViewwith a layout id. Because you aren’t setting a layoutt =(TextView) findViewById(R.id.textView1);is returning null, and when you try and callsetTextit is failing.
