Introduction: Android App Development Assignment This Android App Development Assignment has been developed to understand the fundamental concepts of android application. It will help the developer to design and develop an android application with several features. This feature will be helpful from the user’s perspectives.

Functioning of Application This Android App Development Assignment discusses the application which has the functionality similar to a diary in which the user of the application can add his notes with an appropriate label and a message. Along with these all users will get the time and date at which the notes was saved. For this the user can save entries in five different places which are saved with the name player. The user can also view these entries at five different places.

The user will also have an option menu where the user will have four different options by which the user can perform different tasks.

1. The first option is my profile which will allow the user to view the saved name and password. The user can get his details using this profile.

2. The second option of the option menu is clear list. Using this option the user can clear all the list of the saved entries.

3. The third option is send all entries. Using this user can send all the saved entries using email.

4. The last option is save all entries by which user can save all the entries to the SQLite data base which were earlier saved in the array list.

The main screen of the application is a login type screen in which the user needs to add the data such as name or password. The user also needs to fill the reenter password field. If the password matches the user is redirected to the next home screen else the user need to reenter the field. If the user clicks on the cancel button he/she will exit from the app. [Learn about Java Assignment Help] On the main screen the user will get five player options from where he/she can choose a single player. After selection he/she will be redirected to add notes pages. Now the user will get the following options: 1. The user can view current date, time and day. The user can add label for the notes and can add notes.

2. By clicking on save entries button the user can save all the entries.

3. By clicking on show entries the user can view his/her all the notes.

4. By clicking on previous button the user will be redirected to the previous player.

5. By clicking on the next button the user will be redirected to the next player.

6. By clicking on the home button the user will be redirected to the first page of the app.

The user can enjoy a wonderful app with will provide all the options of the data saving.

Android Architecture Android architecture is a software stack which includes the applications, the operating system, runtime environment, the middleware, the services and the libraries. The architecture can be best represented visually as an outline. Each layer of the stack and the related elements within each and every layer and are tightly integrated and also they provide tuned optimal application and the execution environment for the mobile devices.

The architecture of an android application defines the dependency of the application on different modules. The android application can be created using these dependencies. To create an android application the user can use eclipse or the android studio.

The android is an application of java. All the classes in android app are created in java language.

The java is a platform independent language which is dependent on the byte code. The byte codes are created when the user complies any java program. These byte codes are platform independent and can be executed anywhere on any platform without adding any functionality. The java language is also a secure language. Java language also provides some other feature such as java language is robust, secure, platform independent, architectural neutral, simple, object oriented etc.

The best feature of java language is that it is based on object oriented programming. Everything in java is an object. Using object methods, variables and all the functions of any class can be used in another class.

The class is known as blueprint of objects. The class holds all the methods, variables and the functions which provide the functionality to an android programming. These all can be used with the help of objects.

To run java or android program in a system the system must have a JDK which is java development kit. The user needs to install the java runtime environment which will provide java runtime environment and also the needed library and the tools which are needed for a java program.

In this architecture the common architecture for an application is shown. The architecture of the android application includes the other applications such as the native libraries or the third party libraries. The application also holds the libraries to integrate with other applications. The application also includes the android runtime to execute any application such as virtual machine or other resource to manage the android libraries and also manage the android projects. The libraries also provide the extra feature to use and make the application more useful and appropriate.

The other feature is Linux kernel which allows the users of the application to update the application according to their requirements and also provide a feature to update or edit the application. The android architecture explains dependency of the android application on different modules. The application also provides a way by which the user can get to know the complete dependency of the application.

As various browsers are made for mobile devices but no browser has been used as such to implement this application. The targeted audience is the one who are interested in poker games.

For the implementation of the application the user need to have mobile application with the android operating system. The mobile device should support the android support.

The android applications are not possible to run on the browsers. To run any android application the user need to have a mobile device so that he/she can be able to install the application. The user also needs to have an appropriate version of the android version.

The android is Linux based operating system. The android provides a way to implement all the functionality on software which can be executed on a mobile device easily. The android also provide a easy way to implement all the functionality which can be executed and used on a mobile device without carrying a laptop or without extra need. This player’s app provides an easy way to save the user notes locally so when the user needed these notes he/she can view them anytime, anywhere without need of internet or any other feature. The user is also given a facility such as share of all the saved entries by which the user can save all the entries and can also share them with their friends or someone else when needed.

The user will have a better way to saves notes. The user will not need to carry a diary or some other copy or pen. The user can directly save them by using their mobile device.

Firstly when the user saves the notes they are saved in a static array list. If the user is needed to save them all in database then the user needs to go to menu and selects the save all entries option.

If the user wants to share those entries he/she needs to go to the share all entries option in option menu. Using option menu the user can also clear his/her all the saved entries.

The user can also view his/her profile. These all pages are managed using the fragment on a single Activity. The fragments are light weight and also consume less memory. The layout of the activity can be replaced by many fragments. The fragments are also java class and are used to replace or change the layout of the activity. The fragments also have the same functionality as an activity.

The activity of an android application has five methods such as onStart(), onCreate(), onDestroy(), onBackStackPressed(), onResume() where a fragment holds seven methods. These methods are called life cycle methods of an activity and the fragment.

The android provides some default methods to perform tasks. The user can also create their own methods and can also create their own classes. The layouts or the designing of an android application is done in the xml files. These layouts are saved with the extension .xml.
