// if select index == x , do something
keep in mind that java is not allowed to block the UI thread doing network post
have to wrap this inside one async task, e.g:
new xxxAsync().execute(usageUrl, json);
...
}
catch (Exception ex){
}
finally {
dialog.dismiss();
}
}
});
alertBuilder.create().show();
}
}
