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 learning android application development.
The Android platform is increasingly popular with developers and a dominant force in the global smartphone market. As more businesses develop mobile apps for customer engagement, Android development skills are likely to stay in high demand.
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 deny 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
Online course platforms have android app development courses and android eCommerce app but we still think that most of them are missing the hands-on application part. This course is designed to fill this gap.
My "Android App Development Course with Kotlin" course will take you from beginner to advance level.

This course seems to be very helpful for android application development.
By Vaclav Vlcek on 10/21/2023
This is my first impression after making about 50% of the course. 1. If you don't know Kotlin, you will be a bit lost, because the Kotlin syntax is not explained at all. Same as object-oriented programming logic. 2. The course is narrated by a native speaker. The advantage is that you understand everything properly. However, you feel a bit decoupled from the video. The explanation of the voice actor is simplified, you realize after a while that the actor does not know much about what he is talking about. 3. You will be guided on how to build certain UI components, but I am missing the overall picture of how it is all wired together. I still do not understand how exactly the resources folder 'res' works. 4. As the course progresses, I understand less and less what the instructor does and it is not explained. E.g. "let's return inflater.inflate()...", but there is not explained of what the inflater actually does. "Let's override the function 'onHandleWork()' when implementing 'JobIntentService'". Why this function, what does the function do? But overall, if you want to grasp Android development, this might be a good starting point as a basic introduction.

The instructor explains very well especially for beginners.

Easy and sample way to learn, thank you so much!!
By Birgit Aun on 12/5/2021
Great course for beginners, excellent structure! Each concept is illustrated with a practical example, which really helps to understand it. The charismatic narrator keeps your interest, and doesn't move on too fast, nor too slow - just perfect. 1080p video would be nicer to have. In addition, this course marked skill level "All Levels" should be probably replaced with "beginner". Intermediate/advanced Kotlin/Android developers have nothing much to gain. All in all, one of the best Kotlin beginner course available. Can't wait for more advanced courses!
