问题 I am using persistent object in blackberry to store config details specific to the app. Here is how I am implementing the class public class Preferences implements Persistable { private static PersistentObject persistentObject = PersistentStore.getPersistentObject(0x2759d6ff72264bdbL); private static Hashtable tbl = new Hashtable(); public static void storeLoginToken(String token) { token = removeCharAt(token,0); token = removeCharAt(token,token.length()-1); tbl.put("token", token);

问题 As the title suggests, I would like to create a mobile app that runs in the background and catches "incoming call" events. Moreover I would like to use a Cross-Platform Development Tool to do this. I looked at three tools: PhoneGap, Rhomobile and Appcelerator. But I couldn't find any documentation or examples that suggest they support such events. It seems like the iPhone (correct me if I'm wrong) does not support this but Android and Blackberry do. Did I miss something when I looked at the

问题 Exists an universal phone developement language?

Since iPhone's language isn't used by anything else either, it's pretty much a given that you won't find a universal solution. 回答2: Rhodes by

问题 I have written BlackBerry code to add an image to a ButtonField. I want the whole button to be occupied by the image, but the image is not displayed completely on the ButtonField. There is a lot of margin on the top, left and right of the button. I tried to use cellpadding but it didn't work.
