问题复现：
[2012-03-11 21:13:58] Installation error: INSTALL_FAILED_UPDATE_INCOMPATIBLE
[2012-03-11 21:13:58] Please check logcat output for more details.
[2012-03-11 21:13:58] Launch canceled!
原因分析：
很可能是因为之前卸载应用不彻底，只是简单的rm /data/app/下面的apk文件
解决办法：
办法1:
settings->applications->mange
applications-> select the application->select "unistall".
办法2：
若方法1不可行，可将/data/system/packages.xml中该应用相关信息删掉，然后再次安装即可，因为adb install后，会在packages.xml中添加相应的程序信息。
