How to develop mobile apps for Android?

NEW YORK - July 11, 2016 - PRLog -- When developing mobile apps, you should have a solid plan to make workflow as productive and efficient as you want its results to be. There are three key components that form application's technical backside: Context, Activity, and Intent. Have a look on the stages of Android application development to understand what are the main building blocks and how they relate.

So, what do you do when creating an Android application?

1. Design features and determine activity requirements

There are no specific requirements of what an Android application should be; that is why you are free to create any kind of user interface. When you work on designing prototype screens, first of all, make them stable, responsive and play nice with the rest of the Android system. If a merchant wants to win users' heart, he should pay a great attention exactly to developing user interfaces. It isn't necessary to reinvent the wheel to make users confused with the overstructured functionality - easier to improve already existing features which don't make them overwhelmed. Each designed application feature needs activity classes to be implemented. Already created design is not the only one application development contains - you should take care of each app features' layout that corresponds to your wishes.

2. Work with the application context

Here is located all top-level application functionality that is necessary for accessing settings and resources shared across multiple activity instances. When retrieving the app context, developers use the getApplicationContext method and also unique resource identifier as defined in the automatically generated R.java class. Shared application preferences are usually retrieved by using the getSharedPreferences() method of the app context. This also may be handy for saving and managing configuration settings or other simple data. You can give names to preferences to organize them into categories or in one large set.

When making apps for Android, you should learn more about context. Figuring it out, you will get access to various application features (managing private files, directories, and databases, inspecting and enforcing app permissions).

3. Work with activities

Application Activity is the very same function that is introduced to the screen. The most common way of launching the target activity is done using the application context by startActivity() method with an explicit intent, though the class for launching activity has to be already implemented within the package and be registered as an activity within the Android manifest file.

But what is going to happen if the app is interrupted by another event on a device, for example, phone call? For such cases, there is a number of callback methods in app development that gives a user an opportunity to react quickly and pause or stop his activity before it is shut down.

If you need to implement app preferences, it is essential to use the getPreferences() method of the activity. It is commonly used for saving the current state of the application. For the user to be able to leave the application without a loss, you will need help with the finish() method implementation.

4. Work with intents

So what is an Intent? This is another pillar on which app development is built on. It is a task request that a user sends to the Android system. This action should be matched with the Activity on the Android system to be launched. As a rule, they are used to send data to other app activities.

To conclude

Get started to learn more about the pillars of app development to be aware of how to develop an android app. In summary, these are the general facts: the mechanism of Android application consists of several activities, with their own unique functions and layouts. To have these activities launched, intent objects are matched with the most suitable application activities, and, voila, we can do things the app is created for.
