I really like the approach of this course about the Android app In this course, the instructor focuses on the Android SDK to teach you how to build beautiful applications for smartphones As the course title indicates, it is the complete guide to learn android application development
Android development is a software creation process that focuses on applications, better known as apps, that are compatible with devices running the Android operating system (OS) Because Android is an open-source project, developers have easy access to the Android software development kit (SDK) Many use this kit in conjunction with Kotlin, Java, and C++ programming languages to make their apps The Android SDK tools compile your code along with any data and resource files into an APK, or Android package, which is an archive file that uses an apk suffix One APK file contains all Android app contents used by devices to install your app When the app is complete and ready for release, Android developers can upload their apps to the Google Play Store for users to download for android game development
Chances are, you’ve heard of Android many times, and Do u want to android developer? You may even have an Android smartphone, app android tablet, watch, or TV But what is Android? Android is a mobile operating system (OS) that was designed and developed by Google The Android OS is Linux kernel-based So, what’s “Linux kernel,” and why is that such an essential detail about Android Development?
In a nutshell, Linux kernel is an OS, well, sort of — it’s partially an OS More like a small part of an OS, but an important one The Linux kernel is the layer responsible for interfacing with the device’s hardware and managing the device’s CPU and memory The Android OS is Linux kernel-based because the Linux kernel allows for a more open and customizable OS, which is what Android promotes — any device manufacturer can take the Android OS and make it their own
Imagine how bad it would be if, say, resources from application A read information from another application’s files and vice versa with no constraints — malicious, insecure interactions would take hold and bring the whole system to a halt
The sharing of information (data) between applications is an essential part of building inter-connected applications, so the android OS requires developers to set permissions that users must grant to do certain things For example, for an application to access the phone’s File System (internal files), the user must give access first This means the app developer must let the user know, in advance, what the app they are installing wants to access For example, when a user installs an android app that needs to access the photo gallery or the phone’s camera, the app will ask for permission to access the gallery or the camera The app user has the power to either grant or denies permission App permissions in Android ensure the user’s protection from malware and software viruses
This course is built to help beginners to start making applications in android studio and android application development or android app design
If you want to develop yourself in Android Apps, this course is for you Improve yourself with different applications.
In this course, we cover Android application development with Kotlin from scratch. So, in this course, you will first learn the Kotlin programming language. After learning the Kotlin programming language, we will focus on Android application development with Kotlin. In the Android Application development section, you will have detailed information on many basic subjects such as layouts, components, lists, multi-language support, multi-device support, shared preferences, and much more. After learning the basics of Android development, you will develop 7 different real-world applications. Thanks to these applications, you will master many basic and important Android topics such as SQLite Database, Room Persistence Library, Architectural Components, MVVM (Model-View-View Model), Navigation, Fragment, and much more. Thus, you will have the necessary knowledge to become a real Android developer. You will not only develop applications but also learn how to publish the applications you develop on the Google Play Store.

The topic is very clear and concise
By Katharina Malek on 6/26/2024
Expected the male voice from the intro to continue the course. The female voice sounds like an AI and makes the experience a little rigid. Introduction of the topic is good so far.
