The application can now be started from your Android launcher (named App1 ). You will see
just a black screen. You can exit the application using the BACK button.
There's more...
Don't forget to put the application icon into App1\res\drawable\icon.png . Refer
to the topic's code bundle if you want to build the app quickly, or put your own icon there.
72 x 72 32-bit will do just ine. You can ind the oficial Android icons guidelines at

The oficial documentation on the AndroidManifest.xml ile can be found at http://

Furthermore, you can update your applications without uninstalling the previous version using
the adb -r command-line switch in the following way:

Otherwise, before installing a new version of your application you will have to uninstall the
existing one using the following command:
>adb uninstall <package-name>

project iles. This recipe will focus on the changes to be made to the App1 project in order to
add the C++ code to it.
