I had done Baidu Maps API when there are display problems, it is recommended to look at the Android development forum http://bbs.lbsyun.baidu.com/forumdisplay.php?fid=8
You can look under the DEMO run.
Then you look at the key is not correct.
Finally, is not enough, I suggest you put on the phone to delete the program directory, and try again, I was so successful.
