Question

In my dev console, I get the following error:

android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@405126b8 is not valid; is your activity running?

It’s the follow line: alertDialog = new AlertDialog.Builder(Main.this).create();

Here is my code:

@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.splashscreen);

        alertDialog = new AlertDialog.Builder(Main.this).create();

        LoadData();
}

I dont no whats wrong.
