{
private String TAG;
@Override
public boolean onMenuItemClick(MenuItem item)
{
if (item.getItemId() == saveRoute.getItemId())

alertDialogSaveFile();
//nameInput = "testone.txt";

{
nameInput = saveNameInput.getText().toString();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
}
});
AlertDialog ad = alert.create();

Answer 1
Dialogs in Android aren't synchronous, so it's very likely that the UI thread is finishing onMenuItemClick() before creating/displaying your dialog (dialogs are managed by the enclosing Activity).
Edit: I misunderstood part of your question. Keep the call to alertDialogSaveFile() where it is and put the code that actually saves the file into the onClick() handler. Since dialogs in Android aren't synchronous, you need to perform the save action in the dialog callback itself. It's not possible to show a dialog, wait for the user to respond, and then get the result from the dialog.

I could have stored them on the SD card so there would be no...
