问题 How do I get Arabic running on a BlackBerry? I've downloaded various simulators supporting different carriers and I've not seen Arabic offered as an input language. 回答1: It seems you want to see arabic text in your simulator. For that you have to add a language manually on simulator. It can be done on any simulator. (I have added Herbew on my simulator). I recommend you to use JDE's simulator. To do that you have to find out your simulator's xml file. You can find out in program files/

Code is below: HTML <form action="/jsp/mobile_files/results.jsp" method="get" autocorrect="off" autocapitalize="off"> <h1><input class=

问题 How do I programmatically find direction on a blackberry using GPS? 回答1: With GPS, the minimum resolution is aroud 3 meters. If you take consecutive GPS readings and look for significant changes in a given direction, it will give you a rough estimate of the direction of travel, and thus a probable direction the person is facing. This is not nearly as good as having a magnetic compass, which none of the Blackberries (Blackberrys?) on the market currently have. Some GPS systems have two GPS
