ActivityManager: Warning: Activity not started,...

Activity not started, its current task has been brought to the front的解决办法

在编译NDK程序时，因为修改了一下C++代码，用Cygwin从新编译后，而后在eclipse中运行程序时， console输出界面显示            Warning:Activity not started, its current task has been brought to the front           这时候发现模拟器上显示的内容仍是原来的；           对于这个问题具体缘由还不是很清楚，但在调式的时候发现，这样作能够解决这个问题；首先在Package Explorer中找到要运行的程序，而后点击右键，选中 refresh， 而后再选中run as -----> android application，最后解决了问题；           对比没有通过 refresh 和 通过 refresh 这步， 观察console输出时，发现二者有不一样的部分   如下是通过 refresh 这步在console输出的信息 [2011-05-08 19:13:11 - HelloWjr] Android Launch!

If you run an app from eclipse without it having to recompile (ie no code changes), it doesn't go through the uninstall-install process, it just pushes the application to the front just like you would if you resumed it from the phone. It's not an error but a 'working as intended'！ 也就是在修改了代码后，在没有从新编译这步， 模拟器原来的.apk就不会通过卸载跟从新安装这一步；因此当在eclipse中只是点击运行时，因为如今的程序没有通过编译这一步，因此安装的程序跟原来的同样， 因此在console输出的信息中会出现这一行信息：
