Question

Here, I’m trying to launch a new activity called Detail.class.

final Intent intent = new Intent(this, Detail.class);
courseList.setOnItemClickListener(new AdapterView.OnItemClickListener(){
  @Override
  public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
    startActivity(intent);
  }
});

This is all in the onCreate().

It crashes when trying to start the new activity. Help is appreciated.

Answer 1

check the manifest file to double cross that “Detail” activity has been declared or not..and ya kindly post the logcat to recognize the cause of crash
