What is Android?

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language.

Features

• Application framework enabling reuse and replacement of components
• Dalvik virtual machine optimized for mobile devices
• Integrated browser based on the open source WebKit engine
• Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional)
• SQLite for structured data storage
• Media support for common audio, video, and still image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)
• GSM Telephony (hardware dependent)
• Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
• Camera, GPS, compass, and accelerometer (hardware dependent)
• Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE

Android Architecture

The following diagram shows the major components of the Android operating system. Each section is described in more detail below.

Applications

Android will ship with a set of core applications including an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language.

Application Framework

By providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more.

Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows components to be replaced by the user.

Underlying all applications is a set of services and systems, including:

• A rich and extensible set of Views that can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser
• Content Providers that enable applications to access data from other applications (such as Contacts), or to share their own data
• A Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout files
• A Notification Manager that enables all applications to display custom alerts in the status bar
• An Activity Manager that manages the lifecycle of applications and provides a common navigation backstack

4 Popular opensource Project Management applications

Opensource Project Management Apps are the key to success in many an organization and in personal life for task management too. Open source provides the right platform for development of project management apps that are highly adaptable, flexible and ensure the project renders all deliverables. Introduced here are some of the popular open sources Apps for Project Management.

dotProject

The most delightful fact of opensource apps is that you could work directly on the codes and customize projects perfectly for your business environment. dotProject is one such project management app that ensures you achieve maximum success on every project as enriched features of flexibility, adaptability can be retained even as you tweak the freely available source code to your ecosystem. That the technology is sophisticated and cutting edge is indisputable because of the immense volunteers group, which is skilled and extremely talented.

What you get with dotProject is the satisfaction of tailoring your project management solutions on your time, on your strengths but with well developed and structured technology that ensures you achieve the end deliverables of every projec

What make Achievo a top-rated popular open source project are power features that helps businesses to track the drivers of a project - resources, clients, planning, daily scheduling. Robust features such as time registration and report generation, integrated customer relationship management, human resource management and most importantly scheduling ensure complete project control.

The reason for using such an app would be its complete adaptable features due to the central database interfacing on multiple modules ensuring optimized combination of all intranet applications. This helps applications retain their network environment. As the solutions are server-end, the system can be independently integrated into existing infrastructure.

GanttProject

If you are looking for project management solutions that have high platform migration features then this project is what you need to explore. It comes with powerful features and runs easily on Windows, MacOSX to Linux. It is superb as a project scheduler and essentially helps in overcoming critical situations of project management.

Some of the discerning features include Gantt chart, PERT chart, Interoperating facilities for importing into Microsoft Project as well as spreadsheets along with CSV. WebDAV is another platform for collaborative project development.

Faces

Is Python-based high-function multi-purpose program that is flexible, automated, simulating tool. For those of you familiar and keen on Python features will find working on the ‘Swiss Army knife’ of Project Management a very useful tool to explore.
