Version 2.0 of my Photo Guide app for Android is now available – it is free, no ads either. No special permissions are required to install. Only works on Android 5 or newer.
Works on Android 4.4 and newer.
(Update: An updated version for 4.4 will be available in the store in about 1-2 days – its been uploaded and is awaiting Google processing. In the mean time, the version in the store works on Android 5.x).

This app was originally written using the Eclipse software development system, and the PhoneGap and JQuery Mobile libraries. The new version was converted to use Cordova (similar to PhoneGap) and the project was transferred to the new Android Studio for compilation and testing. This app was NOT written using MIT App Inventor.
As you know, MIT App Inventor is a graphical-based programming system, or a “visual development” system where programs are constructed by dragging and dropping “blocks” onto a Blocks editor.
Arduino, which we mentioned in conjunction with our Bluetooth interface code, is a microcontroller system that is normally programmed in a language similar to the C++ programming language – which is text-based.
Mitov Softwware has introduced a new visual programming system for Arduino. I have not yet had a chance to try this out – the software is in “Beta” test phase and is not yet generally available.
The simplicity of an App Inventor type programming environment might then be available for Arduino applications. This is very exciting. It may be helpful for enabling more kinds of people, with different types of backgrounds than software developers(!) to write code for Arduino boards.

What every beginner absolutely needs to know about the journey ahead
MIT App Inventor makes many things easier – but eventually one must learn to think like a software developer and become familiar with concepts like data structures, algorithms, design patterns, and software engineering design and project management.
Eric Payne has created an Apple Siri – like interface in App Inventor.
You can download his App Inventor source code here from Google Drive. Note that Google Drive displays the content of the .aia file (it is just a .zip file). Click on the “download arrow” icon at top center to download the .aia file to your computer, and then import the .aia file into your App Inventor account.

Most Android apps are written in the Java programming language. Google’s Android software development system converts “source code” (a text file) written in Java, into the code that runs on the Android device.
In many programming language systems, source code is converted into the “machine instructions” of the processor. The processor does not speak “Java” but speaks its own language. A program called a “compiler” converts the original program source code into the “machine language” of the processor.
Many programs for Windows, for example, have been converted into the individual instructions that are processed by an Intel or AMD processor. The “compiler” converts the program source code into a .exe file that contains the machine language instructions of the Intel and AMD processor.
But what if you wanted your program to run on a hardware device that has a Qualcomm or ARM processor?
The pace of change in software development is rapid – popular languages today may already be fading. Pay scales for some niche languages are very high (such as Ruby)- but the market opportunity might not be large or lengthy.
Web applications and mobile applications are the “hot” categories. Within those categories, there are a variety of currently popular software development tools:
This is for advanced software developers only: MIT App Inventor Sources. That’s the actual source code that makes App Inventor work behind the scenes – from the browser based editor to the server side support to the AI Companion. It’s all there.
With access to the source code it is possible to host App Inventor on your own server and it is possible to develop your own App Inventor components (this also requires making a custom version of AI Companion).
See nb136/nb137 release information. If your phone or tablet updates apps automatically, the new update should have been installed already (it was for me).
The new Companion supports internationalization (support for other languages besides English), larger screen sizes for tablets, improvements to the Twitter block interface, and new features to support Fusion Tables.
