Recent Research Into Android Object Recognition and Security

Posted by Charles Norona December - 17 - 2010 - Friday Comments Off

This past semester I have conducted some research in two of my courses that were conducted with Android. The first is an investigation into the privilege escalation attack on Android where activities or components can access restricted components by proxy. The other project was an attempt to implement a Speeded-Up Robust Features (SURF) object recognition mechanism on Android without relying on the computations being done out in the cloud. In other words, the calculating interest point descriptors is done on the mobile device. Reports for both research projects can be found in experiment documents section for those who are interested.

Determining your Device’s Info in Java

Posted by Charles Norona August - 25 - 2010 - Wednesday Comments Off

Sooner or later there will come an instance where one is developing applications on Android and will have to provide some kind of mechanism for making their applications compatible with different hardware platforms. Reasons for using this class can vary from ensuring that the user interface looks proper across different resolutions, changing parameters within algorithms in order to optimize performance, etc. Fortunately, the Android engineers have provided developers the android.os.Build class which can be used to acquire this information. An example of its use is depicted below:


private String TAG = "SSLA";

...

//Determine the local device info for compatibility
Log.i(TAG, "Device information: \n" +
"Board: " + Build.BOARD + "\n" +
"Brand: " + Build.BRAND + "\n" +
"CPU: " + Build.CPU_ABI + "\n" +
"Device: " + Build.DEVICE + "\n" +
"Display: " + Build.DISPLAY + "\n" +
"Fingerprint: " + Build.FINGERPRINT + "\n" +
"Host: " + Build.HOST + "\n" +
"ID: " + Build.ID + "\n" +
"Manufacturer: " + Build.MANUFACTURER + "\n" +
"Model: " + Build.MODEL + "\n" +
"Product: " + Build.PRODUCT + "\n" +
"Tags: " + Build.TAGS + "\n" +
"Time: " + Build.TIME + "\n" +
"Type: " + Build.TYPE + "\n" +
"User: " + Build.USER);

//Example application of using the Build class.
if ((Build.MODEL.equals("T-Mobile G1"))
|| (Build.MODEL.equals("HTC Dream"))
|| (Build.MODEL.equals("Era G1")))//T-Mobile G1 or HTC Dream
slideRate = 6;
else if (Build.MODEL.equals("Nexus One"))//Google Nexus One
slideRate = 4;
else//Default sliding background rate.
slideRate = 4;

The giant log statement produces the following output on the DDMS Logcat:

ESP Course Conclusion and Next Semester Android Plans

Posted by Charles Norona July - 22 - 2010 - Thursday Comments Off

We offered a 3-week course on Android Application development during 6/14/10 to 7/2/10 to 28 high school students, primarily from the Palm Beach and Broward school counties. A team of four faculty members (two each with background in engineering and arts/graphics), six engineering/business student mentors, and an administrator supported the intense effort. The students formed nine teams and presented their applications on 7/2 to a panel of eight judges (with background in engineering, business, and/or graphics). The students received scholarship amounts of $2,400 to $300 per group, depending upon their team rankings. One of these Applications will be posted on the Android market soon, while another six of them will be improved upon further before posting them. These Applications are available for licensing and further improvement. For photographs of the event, see FAU Facebook Group.

We plan to offer two Android courses in the fall’10 semester. The first one, entitled “Software-Hardware CoDesign” will have groups of 3 students who will develop marketable game/social applications on Android. The second course, entitled “Android Robotics” will focus on physical computing. In this latter course, the goal is to develop applications that can coordinate and control the activities of autonomous and concurrent robots.

Please contact me for more information. Thank you.

ESP Course: Week Two

By the closing of week two our students had made significant progress on their projects. In the first week the students only had conceptual designs and artwork while some had the beginnings of pre-rendered artwork created with the use of Autodesk Maya 2010. As week three began our FAU Android group started to see more and more progress as the conceptual thinking of our students slowly came to fruition on the development phones we provided them to work on.
The main focus of week two was finalizing and fleshing out the conceptual work the students had done. One by one Dr. Shankar along with Professors Norman Silva, Fran McAfee, and Dr. Georgian Carvalho met with each group along with their primary mentor to give a peer-mentor review and offer guidance. Most of the students had already implemented menus, settings menus, and/or splash screens but the common remaining task was the implementation of their game or the extension of their program’s main functionality. This would be the focus of week three.

ESP Course: Week One

Posted by Charles Norona June - 21 - 2010 - Monday Comments Off

At the beginning of this week we kicked off our Engineering Scholar’s Program course, Mobile Applications for Google’s Android. This course is designed to provide ambitious, high-achieving high school students an opportunity to develop Android applications for dual-enrollment credit and scholarship awards. So far most of the students seem enthusiastic and excited as we encrouage them to methodically conceptualize a product and mentor them with the development process. This past week proved very busy especially since we asked students to also meet with us on their off-days of Tuesday and Thursday in order to help them flesh out the details of their conceptual development work.
On Monday we went over some standard introductory activites followed by lectures of concept development, project management basics by a business mentor, Skender Fani, a portfolio of available applications which the students can extend, had Professors McAfee and Silva demonstrate a “before and after” evolution of our PingPong example and ended with sessions where we helped them with the Eclipse integrated development environment (IDE) installations and how to use its basic operations. Efforts in concept development were furthered by having some of the students meet with Professors Shankar and Silva as well as our computer engineering/science mentors on the following day.
During Wednesday morning the students were able to show powerpoint presentations of their application storyboards which were a result of their conceptual development work. In the afternoon our FAU Android group demonstrated the basics of Android concepts and touched on some implementation examples followed by Professor McAfee’s demonstration of editing video with the use of Camtasia Studio and Professor Silva’s lecture of using some basic functions of Adobe Photoshop to edit or create artwork. Before adjourning for the day students were suggested to take advantage of Professor McAfee’s expertise in video editing on the following Thursday which many of the students did.
