Areas of Expertise:

Customized GUI with very complex graphic designs

We have handled very complex GUI designs. On many platforms, such UI cannot be developed using standard GUI controls alone. We have developed many custom GUI controls to achieve the results.

Accessing remote server via Web Services

We have developed a large number of client applications for web servers providing services in areas like document sharing, media management, secure communication, data backups and more. These applications typically use web services to communicate with the servers. We have worked with the regular SOAP based web services as well as light weight RESTful web services. Have worked with JSON and XML based communication protocols. We also have light weight applications that communicate to server via SMS rather than the data network.

Large data transfers between server and client, management and operations

Some applications involve large data transfers from the server. For example, a media management solution we developed allows users to access their owned audio / video media from the sever. We periodically synchronize the entire media inventory with these servers. In another case, our application allows user to search a TV program from a 14 day guide for a list of around 2,000 channels.

Multi-thread architectures

Most of the applications we developed are designed for efficient communication with the server without blocking the UI. All these are multi-thread applications with dedicated background threads for communication, data management, and other compute intensive tasks.

Local embedded database - SQLite

We use embedded databases like SQLite to handle large data that needs to be stored locally on the phone. We have also worked with other databases like Embedded SQL Server and found them to be unsuitable for high performance applications

Stringent performance requirements for UI navigation, server communication, and data processing

Some of the database intensive application that we developed had very stringent performance requirements. For example, in the media management application, we needed to be able to download a complete database of up to 30K media items to the client in less than a minute, we needed to load a screen with so many items in the list in less than 2 seconds, and we needed to start playing a new audio stream from the server in less than five seconds. We have achieved all that. At times we have developed custom components for UI or for media player when the standard components on the phone did not provide the required performance.

Secure communication

We have developed applications to support secure communication between a phone and a server or between two phones. This involved standards based encryption mechanisms such as AES, MD5, LFSR, and also some proprietary mechanisms

Support for skins, themes and languages

We have developed multilingual applications that can change the language during the run. We have also supported themes whereby the customers can change the look of the application completely by supplying a set of image files and other UI definitions such as screen sizes and control locations.

Media Player integration for audio/video stream

We have developed applications with integrated audio/video playback. This means that we integrate media player controls in our applications rather than launching the system's media players to operate independently. We have implemented progressive downloads to stream media using HTTP protocol. We have also implemented secure caching mechanisms to pre-fetch media completely or partially so that we can respond quickly to user actions. This also helps in playing the media from local cache for multiple playbacks, thereby reducing the data traffic and also being able to play media when the data connection is not available.

User Authentication

User authentication is implemented by way of validating user Id and password with the remote server. In addition, we can use phone specific id like IMEI number for stronger authentication.

Location based services

We have developed LBS applications that use A-GPS services to determine location of the phone and provide services accordingly. We have used this for applications to assist taxi drivers, advertising, and automated time card entries.

Interfaces like WIFI, Bluetooth

We have used these interfaces for communication with local devices and data transfer.

Integration with phone services like Call, SMS, Email, Phonebook,
Calendar, Reminders, etc.
