Demo Android app using BBBAndroid

Final Report:

Aim of the project: To develop demo Android applications for BeagleBone Black for all its supported interfaces and develop an Android HAL to support future development.

Code repositories:

1) bbbandroidHAL (link): This is the native C code library which can be used to develop Android Application for BeagleBone Black.

2) demoapps-bbbandroid (link): Demo application for BBBAndroid using bbbandroidHAL. It is just to demonstrate how one can develop android applications using bbbandroidHAL.

Documentation:

1) Videos (link): This playlist contains video demonstrations for all the demo apps (i.e. gpio, adc, pwm, i2c, spi, uart, can, usb).

2) Doxygen documentation for bbbandroidHAL (link).

3) Wiki for bbbnadroidHAL (link): This wiki also example codes along with function explanation.

Code completed in GSoC time Frame:

1) HAL Code for GPIO, ADC, PWM, I2C, SPI, UART, CAN and USB.

2) Demo android apps for GPIO, ADC, PWM, I2C, SPI, UART, CAN, USB and for BACON cape.

I have tried to complete almost everything in the proposal, but there is always a chance of improvement. The HAL code and demo apps should help developers accelerate process of Android App development for beaglebone black. I would like to help anyone who wants to try out HAL or wants to develop his/her own Android app for beagle.

It was a great learning experience for me. I would like to thank my mentors Andrew Henderson and Anuj Deshpande for their support and guidance which made it possible for me to complete this project. I would also like to thank this wonderful beagleboard community for their support and Google for giving us this opportunity.

Week #9:

Goals Achieved:

• Android app for CAN completed (link)
• Got sample program for USB working using libusb. (gives lsusb type output)
• Video tutorials for i2c, spi.

Issues:

• Due to heavy rain fall in my area (Bhuj, Kutch) there was a power cut for 2 days and internet is also not working properly. So, I was not able to upload videos. I will upload it soon this week.
• Also I will try to compensate for the this week's work next week.

 Goals for next week:

• Video tutorials for uart and can.
• Wiki content for gpio, pwm, adc, i2c, spi, uart and can.

Week #8:

Goals Achieved:

• Android app for UART completed (link)
• After lot of try I was able to enable can bus.
• Android app for CAN (link).

Issues:

• Even after installing BB-DCAN1 overlay can0 was not created, found that some can bus kernel modules were not loaded in bbbandroid. (issue).
• Send and Read for can bus is working properly in binary through shell but Read is not working properly in apk.

 Goals for next week:

• Video tutorials for i2c, spi, and uart
• Wiki content for gpio, pwm, adc, i2c, spi and uart.

Week #7:

Goals Achieved:

• Android app for SPI for 74HC595 present on bacon cape completed (link).
• Video tutorial for GPIO app (link).
• Video tutorial for PWM app (link).
• Video tutorial for ADC app (link).

Issues:

• Have problem with one of my beaglebone(its not working) :(
• My adxl345 breakout board is also not working. (So could not develop Android app for SPI using it).
• I have ordered new adxl345 breakout board. After that I will try to access it using SPI.

 Goals for next week:

• Android app for UART.
• Sample Code to access USB.
