Mobile computing devices are becoming ubiquitous parts of everyday life. This growth opens a development space for practical applications geared towards decentralized collaboration and coordination. The mobile development platform Android provides rich APIs for interacting with and harnessing devices’ hardware components, but does not provide developers with adequate support for distributed com...

The usage of mobile phones is nearly 3.5 times more than that of personal computers. Android has the largest share among its counter parts like IOS, Windows and Symbian Android applications have a very few restrictions on them. TTS systems on Android are available for many languages but a very few systems of this type are available for Punjabi language. Our research work had the aim to develop ...

Android’s trust-on-first-use application signing model associates developers with a fixed signing key, but lacks a mechanism to transparently update the key or renew their signing certificate. As an advantage, this feature allows application updates to be recognized as authorized by a party with access to the original signing key. Changing keys or certificates requires that end-users manually u...

Smartphones and tablets are the most popular devices because of lightweight, mobile and high-end computational capabilities. Android operating system based smartphones are widely used covering major portion of global smartphone shipment market. This paper proposes a new novel design of a Low Cost Head-Mounted Display (LCHMD). LCHMD is using android operating system based smartphone as a display...

We present the first concept for full-fledged app sandboxing on stock Android. Our approach is based on application virtualization and process-based privilege separation to securely encapsulate untrusted apps in an isolated environment. In contrast to all related work on stock Android, we eliminate the necessity to modify the code of monitored apps, and thereby overcome existing legal concerns ...

At present there are many mobile phones operating systems available in the market but mobile phones with android OS have now become domestic product which was once extravagant product. The reason towards this change is attributed to its varied functionality, ease of use and utility. There are number of tasks performed on it like making call, sending or receiving SMS, music, billing, online shop...

The security model of the Android OS is based on the effective combination of a number of well-known security mechanisms (e.g. statically defined permissions for applications, the isolation offered by the Dalvik Virtual Machine, and the well-known Linux discretionary access control model). Although each security mechanism has been extensively tested and proved to be effective in isolation, thei...

Android is Google's latest open source software platform for mobile devices which has already attained enormous popularity. The purpose of this paper is to describe the development of mobile application for shopping mall using Android platform. A prototype was developed for the shoppers of Bashundhara Shopping Mall of Bangladesh. This prototype will serve as a framework for any such application...

Android and iSO are the two mobile platforms present in almost all smartphones build during last years. Developing an application that targets both platforms is a challenge. A traditional way is to build two di‚erent apps, one in Java for Android, the other in Objective-C for iOS. Xamarin is a framework for developing Android and iOS apps which allows developers to share most of the application...

Android users can face the risk of downloading and installing bad applications on their devices. In fact, many applications may either hide malware, or their expected behavior do not fully follow the user’s expectation. This happens because, at install-time, even if the user is warned with the potential security threat of the application, she often skips this alert message. On Android this is d...
