Question: What items are important in every Android project?
Answer: These are the essential items that are present each time an Android project is created: AndroidManifest.xml, build.xml, bin/, src/, res/, assets/
Question: What is the function of an intent filter?
Answer: Because every component needs to indicate which intents they can respond to, intent filters are used to filter out intents that these components are willing to receive. One or more intent filters are possible, depending on the services and activities that are going to make use of it.
Question: What is an action?
Answer: In Android development, an action is what the intent sender wants to do or expected to get as a response. Most application functionality is based on the intended action.
Question: Describe the Android Framework.
Answer: The Android Framework is an important aspect of the Android Architecture. Here you can find all the classes and methods that developers would need in order to write applications on the Android environment.
Question: How are escape characters used as attribute?
Answer: Escape characters are preceded by double backslashes. For example, a newline character is created using ‘\\n’
Question: What is the importance of Default Resources?
Answer: When default resources, which contain default strings and files, are not present, an error will occur and the app will not run. Resources are placed in specially named subdirectories under the project res/ directory.
Question: What data types are supported by AIDL?
Answer: AIDL has support for the following data types: -string, -charSequence, -List, -Map, -
all native Java data types like int, long, char and Boolean
Question: Enumerate the steps in creating a bounded service through AIDL.
Answer: 1. create the .aidl file, which defines the programming interface, 2. implement the interface, which involves extending the inner abstract Stub class as well as implanting its methods, 3. expose the interface, which involves implementing the service to the clients.

Dear teacher;
Note: This is not an essay project, I just want some suggestions to make my project.
Crowd sourcing:
I have to make a Web API application using dapper.
So my idea was a ToDo application (much better if the features is not only for ToDo app but a hybrid app anything but good) but I make it as a multi-tenant application but I have some problem.
Multi-tenant is where you use the same application to handle multiple customers.
I need more idea/suggestions for the features of my application, can you suggest for some features for my ToDo app? Please make it as a list so that it is easy for me to do

Describe six examples of user interfaces, three should be good design and three should be bad design. Interfaces might be desktop software, web applications, smartphone apps, consumer devices, car dashboards, building entrances, traffic intersections, shower controls, etc.
For each interface, you should:
describe the purpose of the interface and its intended users.
analyze its good and bad points of usability with reference to all the dimensions of usability like
learnability
visibility
efficiency
errors
you may discuss other aspects of usability if you have space and consider them important.
illustrate your analysis with appropriate screenshots or photographs.

DescriptionARENA Game System: ARENA is a multi-user, Web-based system for organizing and conducting tournaments. ARENA is game independent in the sense that organizers can adapt a new game to the ARENA game interface, upload it to the ARENA server, and immediately announce and conduct tournaments with players and spectators located anywhere on the Internet. Organizers can also define new tournament styles, describing how players are mapped to a set of matches and how to compute an overall ranking of players by adding up their victories and losses (hence, figuring out who won the tournament). To recoup their operational costs, organizers can also invite potential sponsors to display advertisement banners during games.Create a class diagram for the Arena Game System based on your use-case diagram that embodies the primary classes. This should be a high-level class diagram with the important objects and their relationships. Make sure to include properties and behavior (high-level) for the…

online Application Design in ppt
The main "point" that has to be made with application design is that application design can be a performance issue.
That is right, the way that your front-end and back-end interact can change how good the efficiency of your system is
the biggest thing is that we need to make sure that our front end has spaces for each one of these fields. the front end is the way your user interacts with your database....period. If there isn't a screen to enter grades, then that student is not going to be entering a grade.
On the flip side, you can't see that your system is going to generate a schedule for a student and not have the fields in the back end, it just doesn't work. Thinking about an application is very much an HCI (human computer interaction) way of thinking.
Make sure you include a "clean" page of the screen you are designing as well as a "marked up" version that shows which field the text field (or other thing) is related to as well as a description…
