Video: Android app insecurity and reversing

In this just released video from the Open Web App Security Project (OWASP) AppSecUSA 2011 conference held in Minneapolis, MN, Mike Park discusses the insecurity of Android “.apk” apps and covers the ease with which Android Apps can be reversed, the ability to store sensitive data locally, and how these apps can be trojaned to […]

FT311D errata: The IC doesn’t work with Android v4.1 and above

We designed a breakout board for the FT311D Android Open Accessory (AOA) ICs. We got the prototypes in our workshop, and in the free PCB drawer. Only thing missing is for FTDI to start selling them. In this waiting period we stumbled onto the errata for this IC. There are two errors reported in the […]

I2C communications and Android applications

Here’s an open source project by Dimitar Gamishev which demonstrates how to communicate using I2C in Android applications. As shown in this project Dimitar uses this code with an A13-OLinuXino running Android to drive relays and read ADCs and GPIOs on a connected MOD-IO board. Tsvetan Usunov via the contact form.

FTDI releases the FT311D USB host IC which provides easy communication with Android devices

  FTDI released the FT311D USB host IC for easy communication with Android devices. It features 7 GPIOs, one I2C peripheral, one UART, one SPI, and 4 PWM peripherals. The device acts as a USB host to an Android device, while the Android’s app directly controls the peripherals on the IC. The device is configurable […]

A13-OLinuXino first time Android boot

Olimex is hard at work to roll out the A13 based OLinuXino by September. In the latest news they were able to flash the device with a custom Android build. Dimitar Gamishev learned that we have A13-OLinuXino prototypes and came to our office after work, he already had pre-built Android image, so after spending some […]

Unboxing of the Meizu MX Android phone and gaining root access with the Bus Pirate

Adam unboxes the Meizu Mx and gets root access using the Bus Pirate. The phone is torn down to the main-board to gain access to the UART test points on the board. After that it was a simple matter of connecting the Bus Pirate to the phones UART lines. Also check out Adam’s rant on […]

DIY USB OTG cable connects Flash disk to Android phone

Rohit de Sa has an Android phone with a feature known as USB On The Go (OTG), allowing the phone to act as either a host or slave. Thus, it can interface with various USB devices such as mice, keyboards, etc. Since in his region a USB OTG cable is not easily available, Rohit went […]

BTSwitch project controls devices with Android smartphone

Luca Dentella writes, “Hello! I’ve just published my latest project, an Arduino-based bluetooth switch you can control via Android App.” The design uses an Android smartphone app which communicates via Bluetooth with a Bluegiga WT11 module, which in turn communicates with an Arduino controlling a relay switch. Luca’s plans and code are available on his […]

Contest: Changing the World with Android

Microcontroller Central is sponsoring a contest with the theme, “Changing the World with Android.” According to MC: To enter, submit a design proposal for an MCU-based device that uses an Android platform (tablet, smartphone, etc.) as the user/control interface, via the reader boards. The more detail the better, but entries should be at least 100 […]
