New Feature! Save your blocks code as an image file! Print blocks code!

App Inventor Elsa Consulting passes this along on Facebook:

Tip: Right click for download blocks as png Image!

In case the link does not work, here’s an example – right click on a blank space in the Blocks editor view and get this pop up menu:

SaveBlocksAsImage

Select “Download Blocks as Image” and it downloads a graphic image of all of your blocks – which you can then print out if you want – finally!!!!!!

(FYI – my posting here on this blog is sparse for a little while longer. Been remodeling our kitchen which means lots of time and living in a mess. But I have gotten a lot of work done on Volume 4 of the App Inventor guide. Hope to introduce Volume 4 in about one month – with many neat features coming!)

Use Projects | Checkpoint to save a “Snap shot” of your App Inventor project

Tip – Using Projects | Checkpoint

As we develop our app code, we occassionally make changes that do not work. Sometimes our programming breaks a working app! When that occurs, we wish we had saved an copy of the file so that we can return to the original code before we messed it up.

There are several ways to save a copy:

App Inventor 2 volume 2 status

Volume 1 of App Inventor 2: Tutorial is available at Amazon.com.

Volume 2 is in development and will cover a lot of the Android features – like camera and database usage – key elements to create real-world applications.

Volume 2 is completely outlined. But before I start writing, I am creating a moderately large sample application to be used for the examples in the text. Design of the sample application is under way.

I am also working on video tutorials for learning App Inventor 2 – these will end up on Youtube as they get completed.

 

Welcome to the App Inventor 2 Guide and Tutorial blog

MIT App Inventor 2 is the fast and easy way to create Android apps for smart phones and tablets.

App Inventor provides a “what you see is what you get” drag and drop user interface designer, coupled with a unique graphical programming system that arranges program building “blocks” to define actions and behaviors. This makes for a simplified Android smart phone app development system that is quick to learn and quick to put to use developing your own apps.

You do not need to be programmer to use App Inventor (although any prior programming experience is valuable).

Using App Inventor, you can create many kinds of apps including personal productivity, business, games, multimedia, photography and others.

The user interface is drawn in the “Designer” and the program is created using the “Blocks” editor. A sample program in “Blocks” is shown here:

CaptureThese program components are dragged out of a palette of program “blocks” to define what the program does.

App Inventor does have some limitations – you cannot create all types of apps that are possible using the more complex Java programming language, Eclipse Integrated Development Environment and the Android SDK. But, you can create a wide variety of applications using App Inventor.

App Inventor has some limits on program size – you will notice especially that as your programs become large, the performance of the program “Designer” editor will slow down.
