The cool features that come with the app are of interest to users. Applications make phones "smart", and by their strengths, applications have revolutionized the way we do today.

Master the Language

XML and Java are the main 2 programming languages used in Android App development. Therefore, understanding and mastering these programming languages is a prerequisite for developing Android applications. Some of the basics of the Java programming language include:

 

  • Package
  • Classes and Objects
  • Interface and Inheritance
  • Strings and numbers, generics,
  • Concurrent

A proper understanding of Java and XML will help you build/develop a more robust and elegant Android app.

Familia with appropriate development tools and the environment

It is important to be familiar with building automation tools and integrated development environments before you start developing applications

Learn the components of the application

Application components are the building blocks of Android application development.

There are five different types of application components each serving a distinct purpose with a distinct life cycle that determines how to create and destroy them. Include

 

Activities: A one-screen component with a user interface (for example, an e-mail application may include one activity that displays a list of new e-mail messages, another activity that creates e-mail messages, and other e-mail messages to read). Activities work together to form a coherent user experience in the application. However, each of them is independent

 

Services: This is a plugin that runs in the background to perform work for remote operations or processes that last for a long time. The user interface does not provide (for example, music may be played in the background while the user is in a different application)

Content Providers: This is the component that manages a shared set of application data. With this component, data stored in either the file system, the Web, or the SQLite database can be queried or even modified (as long as the content provider allows). This component also serves to write and read data that is not shared and is specific to your app.

 

Broadcast receivers: This is the component that responds to system-wide radio ads. Most broadcast receivers originate from the system, and although they do not display a user interface, they can create a status bar notification that alerts the user when a broadcast event occurs. Generally, the gate is for other components, and it only works minimally.

 

Component Activation: A synchronized message is referred to as the intention to activate 3 of the four components (ie, services, activities, and broadcast receivers). Intents also link individual components to each other at runtime, regardless of whether the component is a component of your application.

Awareness of fragmentation and application of Android and threads and the burdens and tasks

Android is a disintegrated market with many different devices and operating system versions.

Note that if your device supports more devices and/or versions, it definitely requires more maintenance and testing as well as related costs. The opposite is also true. You also need the appropriate fonts, assets and schemas that will help ensure the best possible experience in different screen properties. You must also consider the Android-enabled sensor set or user interface facilities.

Make the right choice on the required tools

The simple tools you need to develop your Android app are just a Mac or Windows PC, and any kind of Linux, Eclipse, ADT Plugin, and Android SDK - all free. You can see the installation guide on Google to learn how to set up your development environment; it provides documentation for everything you need. Android has some unique parameters to keep in mind when writing your Android app. Some include them

 

Performance and Response: You must always respond to user input within five seconds otherwise the operating system will perform an ANR. (The ANR application does not respond - the only option you will have is to force your application to close.)

Users will notice a slowdown of more than 100 milliseconds: As mentioned above, the UI thread will never be blocked because it is only one.

Limited resources: The icon lock feature (a mechanism that forces the device to do something specific through the device's recommendation to sleep by the battery manager) must be used. Do not inquire about devices unnecessarily (for example, GPS or accelerometer) because the battery will run quickly
