Question

I’m opening an Activity using this:

startActivity(new Intent(Parent.this, Child.class));

And on the child, I have this code on the onCreate function (the if contains more than just true, of course):

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (true) {
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setPositiveButton("OK", null);
        builder.setTitle("Error");
        builder.setMessage("Connection error, please try later.")
            .show();
        finishActivity(0);
        return;
    }
}

Why is the activity not closing? I get the alert box, but then I have to tap the “back” button to go back.

Answer 1

Try using the finish() method to close the Activity.
