IOIO For Android: Building Your First App

Today, we will share with you how to develop your first Android IOIO app. This tutorial is very simple as we will show you how to use your Samsung Galaxy S3 to control the IOIO for Android board build in LED. The objective of this tutorial is show you how to setup eclipse and Android SDK setting to compile the program to develop Android application (.Apk) for the Android IOIO board.

Previous tutorial, we have discussed lot of the Android IOIO board hardware setup tutorial. So, make sure that you already know all the pin IO for the IOIO board, especially the voltage input and output. So, the pin Vin is Voltage input pin, the voltage range is from 5v-12v.Here, the power source we are using is 12v, 1mA. Please take note that the 3.3v and 5v is voltage output pin, so don’t connect the power in to both of this pin. After, you have setup the Android IOIO Board, now you need to setup Android compile software on your PC.

The free software you need is the Eclipse and Android SDK, you can download and follow the tutorial here (Link) how to setup this software into your PC.

For better performance, we are recommend that your PC at least powered by Intel core i5 processor. Then here is the tutorial how to build your first App for Android IOIO:

Step1: Download the sample Android IOIO software “App-IOIO0326.zip” from here (Link). The unzip this folder”App-IOIO0326.zip” to your PC.

Step 2: Open Eclipse, then goto File > Import, and select Existing Projects Into Workspace. Then click Next.

Step 3: Setting Menu will Pop Up. Select ‘Select Root Directory’ and navigate to the file you just unzipped and point to the HelloIOIO folder found in /applications/HelloIOIO. Be sure the check box is selected for your project. Now click Finish.

Step 4: You has success setup HelloIOIO in your project. Now you need link this project to the IOIO library and IOIO Bluetooth Library.

Step 5: Open Eclipse, then goto File > Import, and select Existing Projects Into Workspace. Then click Next. Setting Menu will Pop Up. Select ‘Select Root Directory’ and navigate to the file you just unzipped and point to the IOIOLib file. Now click Finish.

Step 6: You should now have IOIOLib file. in your project explorer in Eclipse.

Step 7: Open Eclipse, then goto File > Import, and select Existing Projects Into Workspace. Then click Next. Setting Menu will Pop Up. Select ‘Select Root Directory’ and navigate to the file you just unzipped and point to the IOIOLibBT file. Now click Finish.

Step 8: You should now have IOIOLibBT. in your project explorer in Eclipse.

Step 9: Now, you have HelloIOIO, IOIOLib and IOIOLibBT in your project explorer in Eclipse.

Step 10: Right click to the ioio.examples.hell.MainActivity, then click Properties.

Setup 11: The Properties Menu will prompt up, make sure the ‘Project Build Target’ is properly selected according to the specific Android OS you are using.

Step 12: The compiler software setting is complete, now you can test run this application on your PC, RUN As> Android Application.

Step 13: OK, now we want to install this application into Samsung Galaxy S3 to communicate to the Android IOIO board. Go to Android IOIO >Applications>HelloIOIO> Bin, and the Copy “ioio.examples.hello.MainActivity.apk” into your Galaxy S3.

Step 14: On you Galaxy S3, go to settings>Developer options to enable the USB Debugging Mode (to allow your Galaxy S3 to Android IOIO board). You also need Settings>Security, to enable Unknown Sources (to allow install ioio.examples.hello.MainActivity.apk).

Step 15: Install ioio.examples.hello.MainActivity.apk on your Galaxy S3.

Step 16: Connect your Galaxy S3 to the Android IOIO Board via USB Cable.

Step 17: Now, adjust the Android IOIO Board “chg” potentiometer until Galaxy S3 show that USB debugging is connected in the notification bar.

That all!. You can click the application Button to On and Off the Android IOIO Board LED.
