PAPER ON ANDROID
ANDROID.pdf (Size: 236.93 KB / Downloads: 88) ABSTRACT The unveiling of the Android platform on was announced with the founding of the Open Handset Alliance, a consortium of 48 hardware, software, and telecom companies devoted to advancing open standards for mobile devices. Google has made most of the Android platform available under the Apache free-software and open source license. Android is a freely downloadable open source software stack for mobile devices that includes an operating system, middleware and key applications based on Linux and Java. Google developed Android collaboratively as part of the Open Handset Alliance, a group of more than 30 mobile and technology companies working to open up the mobile handset environment. Android's development kit supports many of the standard packages used by Jetty, and so, due to that fact and Jetty's modularity and lightweight footprint, it was possible to port Jetty to it so that it will be able to run on the Android platform. Introduction Android is a software platform and operating system for mobile devices, based on the Linux kernel, and developed by Google and later the Open Handset Alliance. It allows developers to write managed code in the Java language, controlling the device via Google-developed Java libraries. Applications written in C and other languages can be compiled to ARM native code and run, but this development path isn't officially supported by Google. Android is available as open source. Google threw open the entire source code (including network and telephony stacks) that were not available previously, under an Apache license. Certain parts that relate to a specific hardware can't be made open and are not considered part of the Android platform. With Apache License, vendors are free to add proprietary extensions without submitting those back to the open source community. While Google's contributions to this platform are expected to remain open-sourced, the branches could explode using varieties of licenses. Activity Activities are the most common of the four Android building blocks. An activity is usually a single screen in your application. Each activity is implemented as a single class that extends the Activity base class. Your class will display a user interface composed of Views and respond to events. Most applications consist of multiple screens. For example, a text messaging application might have one screen that shows a list of contacts to send messages to, a second screen to write the message to the chosen contact, and other screens to review old messages or change settings. Each of these screens would be implemented as an activity. Moving to another screen is accomplished by a starting a new activity. In some cases and activity may return a value to the previous activity -- for example an activity that lets the user pick a photo would return the chosen photo to the caller. BROADCAST INET RECEIVER You can use a Broadcast Receiver when you want code in your application to execute in reaction to an external event, for example, when the phone rings, or when the data network is available, or when it's midnight. Broadcast Receivers do not display a UI, although they may use the Notification Manager to alert the user if something interesting has happened. Broadcast Receivers are registered in AndroidManifest.xml, but you can also register them from code using Context.registerReceiver (). Your application does not have to be running for its BroadcastReceivers to be called; the system will start your application, if necessary, when a BroadcastReceiver is triggered. Applications can also send their own intent broadcasts to others with Context.sendBroadcast (). CONTENT PROVIDER Applications can store their data in files, an SQLite database, or any other mechanism that makes sense. A content provider, however, is useful if you want your application's data to be shared with other applications. A content provider is a class that implements a standard set of methods to let other applications store and retrieve the type of data that is handled by that content provider. Not every application needs to have all four, but your application will be written with some combination of these. All the components needed for android application should listed in an xml file called AndroidManifest.xml. This is an XML file where you declare the components of your application and what their capabilities and requirements are. Storing, Retrieving and Exposing Data A typical desktop operating system provides a common file system that any application can use to store and read files that can be read by other applications. Android uses a different system on Android, all application data are private to that application. However, Android also provides a standard way for an application to expose its private data to other applications. This section describes the many ways that an application can store and retrieve data, expose its data to other applications, and also how you can request data from other applications that expose their data. Security and Permissions in Android Android is a multi-process system, where each application (and parts of the system) runs in its own process. Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications. Additional finer-grained security features are provided through a "permission" mechanism that enforces restrictions on the specific operations that a particular process can perform, and per-URI permissions for granting ad-hoc access to specific pieces of data. Application Signing All Android applications (.apk files) must be signed with a certificate whose private key is held by their developer. This certificate identifies the author of the application. The certificate does not need to be signed by a certificate authority: it is perfectly allowable, and typical, for Android applications to use self-signed certificates. The certificate is used only to establish trust relationships between applications, not for wholesale control over whether an application can be installed. The most significant ways that signatures impact security is by determining who can access signature-based permissions and who can share user IDs. User IDs and File Access Each Android package (.apk) file installed on the device is given its own unique Linux user ID, creating a sandbox for it and preventing it from touching other applications (or other applications from touching it). This user ID is assigned to it when the application is installed on the device, and remains constant for the duration of its life on that device. Using Permissions A basic Android application has no permissions associated with it, meaning it can not do anything that would adversely impact the user experience or any data on the device. To make use of protected features of the device, you must include in your AndroidManifest.xml one or more <uses-permission> tags declaring the permissions that your application needs. The permissions provided by the Android system can be found at Manifest. permission. Any application may also define and enforce its own permissions, so this is not a comprehensive list of all possible permissions.
