Misc Advanced AppInventor Concepts

+Using Multiple Screens in Apps

You can have more than one screen in your app and move back and forth

Lets watch a very concise video to learn how to use this

http://www.youtube.com/watch?v=9DaT_XTvpGY&feature=related

Want to try it?

Create an app for yourself as an instructor Main page –name, place for picture, title, etc Contact me – phone, mailing address, office number, email About me – brief bio statement You could add others like class schedule, interests etc.

+Saving and Sharing

To share, backup or otherwise transfer source code you will download a .zip file

To share a runnable app you will download an .apk file

How do I do each of these???

Let’s investigate

Can I use QR codes to distribute? http://qrcode.kaywa.com/ Get a scanner in the Marketplace

+Want to distribute your app?

Local distribution Download Setup QR code Email Put on website

-Alternative-App-Stores

+Conversion

+Building your own Web Databases and APIs

Hosting a web database

Creating AppInventor compliant APIs

Google App Engine https://developers.google.com/appengine/

+Other Resources

Look at file on Wiki

Other examples on Wiki

+Build your own app

By yourself or with a partner Define an idea for an app Set goals Identify the steps needed Identify the components needed to accomplish the steps Design the GUI Build the blocks Test it Define and try some extensions

+Java and bridging

The is an official bridge to Java SDK and at least one “enhanced” third party one

The essential concept in both cases is Provide AppInventor widgets as Java classes to reduce our

coding workload Make it easier to transition from the AppInventor

environment to true and full-blown Java development

You will need to install and setup Eclipse, the Android SDK, Bridge SDK and some Android Version files in order to do any kind of development using Java See setup instructions

+Setup Instructions

For Windows http://javasrilankansupport.blogspot.com/2012/04/how-to-set

For Mac http://learnaboutandroid.blogspot.com/2011/05/setting-up-yo

Also install one of the Bridge SDKs previously discussed

if( component.equals( btnButton1 ) && eventName.equals( "Click" ) )btnButton1_Click();

else if( component.equals( asnAccelerometerSensor1 ) && eventName.equals( "Shaking" ) )asnAccelerometerSensor1_Shaking();
