Title Body

I'm trying to move onto the third activity in a sequence. Going from the main activity to the second one works fine but when I try to go to the third activity from the second I the application crashes. Here's my code for the second activity: package com.example.helloandroid; import android.app.Activity; //other imports here public class Game extends Activity implements OnClickListener { private static final String TAG = "Matrix"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.matrix); View doneButton = findViewById(R.id.done_button); doneButton.setOnClickListener(this); } public void onClick(View v) { switch (v.getId()) { case R.id.done_button: Intent k = new Intent(this, GameTwo.class); startActivity(k); //finish(); break; } } } And the code for the third activity: package com.example.helloandroid; import android.app.Activity; //other imports here public class GameTwo extends Activity { private static final String TAG = "Matrix"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.matrixtwo); View donetwoButton = findViewById(R.id.donetwo_button); } }
