Example text

Simple yet very powerful — it lets you create new projects, delete existing projects, and upload and download source code. Now, on to the Design part of App Inventor Designer. Design Design, the second of the two screens making up the App Inventor Designer online application portion of Google App Inventor, looks like the following screenshot. We see this when we open a project in the My Projects screen that we explored just previously or log on when we have existing projects (App Inventor automatically opens in the last project you were working on).

This link, as we are notified in the previous mini dialog window, works only if you are logged in to your Google account. But, you can open your Design screen and let anyone you like who has an Android phone or other device to install the app. But, this is very limited sharing, meant primarily for your ease in testing apps. Toward the end of this book, I'll show you how to package apps for the Android Marketplace and share them (even sell them) to the world!

The files are now gone. But, what about the security of files you really want to keep?

Still, it does not hurt to have our own personal backups for those of us who like to be doubly sure (I raise my hand here). More Actions gives us a way to download (get project source code out of My Projects) or upload (load source code into My Projects).
