I believe that the manufacturers also hear the voices of our engineers who like to write programs everywhere, so starting from the end of 2000, there will be a lot of support for Java mobile phone will soon be launched, of course, these manufacturers also provide a mobile phone development Program SDK, we can finally write small programs on the phone to amuse themselves! It's a dream I've been wa

In this case, the company will spend half of its time walk
