Try change the protected boolean onTap(int index) as below :

@Override
protected boolean onTap(int index) {
 OverlayItem item = mapOverlays.get(index);
 AlertDialog.Builder dialog = new AlertDialog.Builder(this.context);
 dialog.setTitle(item.getTitle());
 dialog.setMessage(item.getSnippet());
 dialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
    }
});
 AlertDialog alertDialog=dialog.create();
 alertDialog.show();
 return true;

}

You need to create the AlertDialog from the DialogBuilder.

Change code : itemizedOverlay2 = new AddItemizedOverlay(drawable_client); to itemizedOverlay2 = new AddItemizedOverlay(drawable_client, ActivityName.this); Where ActivityName referes to the name of the actvity. – Eldhose M Babu Aug 28 '12 at 08:30
