4) Which programming language is used for Android App development?
Java is the official and widely used programming language for Android App development. It also supports C/ C++ language using NDK (Android Native Development). However, the major parts of Android are written in Java programming language and the APIs are also designed primarily from Java.
5) What are the core building blocks of android?
Activity, View, Intent, Service, Content Provider, Fragment etc.
6) Define and explain the Android Framework?
Android framework is a set of API’s using which the Android developers write code for the mobile apps. it is an essential part of the Android Architecture. It contains the methods and classes to write the programming code.
Android framework includes a different set of tools to create image pane, text field, buttons, etc. It also includes “Activities” with which the user interacts and “Services”, which are the programs that run in the background. It is a package of different components like Intents, Broadcast Receivers, Content Providers, etc.
7) What is Android Architecture?
Android architecture refers to the different layers in the Android stack. It includes your operating system, middleware, and important applications. Each layer in the architecture provides different services to the layer just above it. The four layers in the Android stack are:
- Linux Kernel
- Android Framework
- Android Applications
8) What are the important core components of Android.
The core components of Android operating systems are:
- Content Provider
9) What are the different kinds of context in Android?
Context defines the current state of an App. Context provides access to creating new activity instance, access databases, start a service, etc. There is a base class ApplicationContext, and subclasses for components: Activity, Service.
10) What is action in Android?
In Android, an action is a description of something that an intent sender desires.
11) What are the three key loops when monitoring an activity.
Entire lifetime: An activity that happens between onCreate and onDestroy

public virtual View FindViewById (Int32 id)
13) How will you pass data to sub-activities?
We can use bundles in order to pass data to sub-activities. There are HashMaps that take trivial data types. These bundles transport information from one activity to another.
Bundle b=new Bundle();
i.putExtras(b); //where I is intent
14) What is a Sticky Intent?
A Sticky Intent is a broadcast from sendStickyBroadcast() method which floats around even after the broadcast, allowing others to collect data from it.
15) What is the difference between a fragment and an activity?
Activity is a single, focused operation that a user can perform. For example such as dial a number, take a picture, send an email, view a map etc.
Fragment is a modular section of an activity. It has its own lifecycle and input events, and which can be added or removed at will. A fragment’s lifecycle is directly affected by its host activity’s lifecycle i.e. when the activity is paused, so are all fragments in it will get paused, and when the activity is destroyed, so are all of its fragments.
16) What is the importance of an emulator in Android?
- The emulator lets you play around an interface that acts as if it were an actual device.
- It also let you write and test codes, and even debug.
- It acts as a safe place for testing codes especially if it is in the early design phase.

Top 13 Checklist for Launching Your Android App on Google Play
Getting an app on Google Play is a great achievement. Before you share your hard work with the world, it is necessary to go through some hoops to keep up the quality reputation that Google Play has. Although the process is similar to Apple, but there are some key differences that will need to be adjusted in order to have a successful experience. Preparing a launch strategy beforehand will save frustration and additional expenses along the journey.
1.Determine the Content Rating of Your App
The content rating is one of the areas where there is some additional flexibility compared to other platforms. Google Play trusts the developer to set age limits before release. Categories include everyone, low maturity, medium maturity, and high maturity. Users can set their preference from their devices, so only the most appropriate search results will appear. The rating you assign can be changed through the Developer Console once your app goes live.
2. Will Your App Be Free?
Create your monetization strategy up front. This involves a couple of different considerations. First, will your app be free or paid? This is important, because on Google Play, you cannot charge for the initial download of an app after acceptance. You will be able to still accept money for features in the app by setting up a Google Merchant Account, which will be addressed later on. Anyone can download a free app. For a user to acquire a priced app, they must be in a supported location, and have appropriate billing already established. Keep in mind that this will limit the availability of your work.
3. Test on Multiple Android Devices
Quality is one of the most essential standards that must be met before your app can contend in the marketplace. The quality of your app is extremely important as large number of great apps are already available. In addition, the number of Android devices that your app needs to be compatible with is at an all-time high. So, your aspiring app must perform flawlessly for users with different system requirements. Customizing it for tablets is another issue altogether, because of its larger screen size. Test the app thoroughly on a variety of phones to catch bugs early.
4. Invest in Video to Market Your App
Because Google owns YouTube, video support for marketing your app is another step in your launch checklist. Any videos that showcase your app will be displayed on your store listing page, and in search results. Professional quality graphics will enhance both your sales and success. Take advantage of the unique format, demonstrate how your app is used, and clarify what it looks like inside. The visual design of these should be cohesive with your entire campaign. Because they will be displayed globally, plan to shoot multiple videos for each country you intend to target.
5. Pay Google Play’s Registration Fee
The registration fee is only a one-time fee of $25. This is less expensive than the Apple Store, and due to the prevalence of Android devices, makes it an attractive option for first-time developers. Once you have an account, you will be granted access to the Developer Console to publish and manage all of your future apps in the same place.
6.Begin the Localization Process Early
Targeting your app to users in more than one country will require that you plan and provide adequate time to design location-specific content. The benefit of this is increased visibility and sales. You need to focus on images, strings, store listings, screenshots and other graphic support materials. Google Play’s localization checklist suggests changing dates, times, currencies, languages, and device testing to suit all of your audiences.
7. Create Additional Promotional Graphics
Promotional Graphics are what your users will see before they make the decision to download or purchase. The logo and icon need to remain consistent with the store logo page. Even if you plan to release many different apps, Google Play requires that the quality and aesthetic remain consistent across everything your brand offers.
8. Have at Least 2 Screenshots of the Finished Product
It will be required that you submit 2 screenshots of the finished app along with the build. This can easily be done by using Photoshop to add loader page images to an existing image of an Android phone or tablet. These screenshots are an excellent way to promote interesting features within your app that will encourage people to engage with your product.
9. Keep the Total Size under 100MB
Although there are exceptions for certain extension packages, a good rule of thumb is to keep total download size to under 100mb. If your app takes too long to work, then users will loose interest and you will lose sales. This rule will also make it easier on the team regarding development time and budget considerations.
10. Setup a Google Checkout Merchant Account
A Google Merchant Account is required for any priced apps, or in-app purchases offered. Once you have a publisher account, this will be simple to set-up, and you can start receiving payments.
11. Familiarize Yourself with the Developer Console
The Developer Console is where you will manage your submission, Merchant Account, global assets, and promotional materials. Here you can build product pages, adjust distribution, and publish from any web browser. Google Play allows beta distribution to a closed contact list.
12. Offer Continuous App Support
Offering support after updates will be essential to the satisfaction of your customers. This will provide positive ratings and referrals. Your store listing page is an ideal place to post a support email link. Consider a generous refund policy to foster trust and encourage future purchases from your store.
13. Track Analytics
Tracking the performance of your app is necessary to make future improvements, and drive revenue over time. So, Google Analytics can help you measure and achieve these goals. E-commerce tracking shows in-app purchases, and AdMob will help with advertising data.
In order to release an app on Google Play, first of all you need to start by setting up a publisher account. This is where you will provide information about yourself or company and the app you wish to release. Identify your content rating, pricing structure, target audience, testing strategy, and required promotional assets early to gain success later on. After your release, monitor device standards, and provide regular updates. Supporting your customers continuously will provide them with a great experience, as well as teach you about what you need to stay competitive in the mobile application industry long-term.
