Android Programming

• Traditionally to program Android powered devices you would use such tools as “Eclipse”, a Java IDE or “App Inventor” a web based development tool.

• “App inventor” has been dropped by Google • Each of these tools are “free” and use “open the open source” licensing

Android Programming

• Problem is five fold: – Learning new development tools – Learning new paradigms & vocabulary – Developing user interface without visual tools – Learning new programming language – Pain getting developed software to actual device

Android Programming

• An easy to learn, and easy to use “new” programming tool for Android powered devices is “Basic4Android” • Uses a Visual Basic (© Microsoft) like language • IDE with visual design of GUI in both virtual device, emulator & actual device • Costs $49 USD (Standard), $99 USD for Enterprise version

Android Programming – Basic4Android

• Free evaluation version can be used for 30 days • Very robust downloadable manual & user support forum • RAD tool of choice

Note:

Developing applications and using the emulator to test is fine, but you must have access to a real Android device(s) and test. You should always test against the type of devices that your software is targeted.
