After you've installed your app's .bar file, you can launch your app. If you don't have an HMI running on your target, you can still run your app from the command line.
To launch your app:
Run the launch command to start the app:
launch <project_name>
For example, launch com.example.hello.
To launch the app, the Application Launcher echos the command to launch the app to a PPS object:
echo "msg::start\ndat::${APP},ORIENTATION=0\nid::${APP}" > /pps/services/launcher/control
where ${APP} is the app's name in the /apps directory.
