在根目录编译：
make update-api -j8
mmm framework/base/service
把service.jar和service.odex push到相应目录。
app内使用方法：
WatchManager watchManager =(WatchManager) getSystemService(Context.WATCH_SERVICE);
if(watchManager != null){
int step = watchManager.getTargetStep();
Log.e("Tim_SS","watchserver app step=" + step);
}
