Q. How can I monetize it✨?
In our app, we will learn how to monetize by directly pasting advertisements . There are several ways to monetize an app. You can charge for the app itself, induce payments within the app, or make money by pasting advertisements. For beginners, it may be better to make a small profit through traffic by pasting advertisements rather than an app that requires users to pay. Try monetization, which seemed far away, by directly pasting advertisements in Mise Mise Clone Coding.
#Finally released.
Joyce, the author of a book that achieved the TOP 10 in the Aladdin and Yes24 app programming fields while giving YouTube lectures on Android, has finally opened a lecture on Inflearn!
Originally, he was only planning to film free lectures, but he decided to convert them to paid lectures and give students more detailed and immediate Q&A, so he filmed the lectures like this. There were some twists and turns before the release, but the course currently has a 5-star rating.
Join Joyce for your first Android lesson!
Even complete beginners can understand it Android Lecture 😉
The author of the book 『Joyce's Android App Programming with Kotlin』, which achieved 2nd place in the Aladdin Mobile Programming category and was selected for the 2022 Sejong Book Academic category, is finally presenting to you the lectures he filmed after months of hard work.
This course is suitable for everyone, from absolute beginners to Android developers who want to have a solid grasp of Android concepts . After effectively learning Android concepts, we will create three apps one by one, monetize them with ads, and then upload them to the Google Play Store. After finishing this course, you will become a developer who can quickly learn and implement any new concept.
Maybe studying the basic concepts for the first time can be boring. I explained the key contents with many examples and analogies so that you can study easily and enjoyably. Learn the hard theory without getting bored!
If there is something that is difficult to understand in terms of logic, I have made it as logical as possible through diagrams. Learn how to organize code logically and start programming Android properly.
We provide lesson plans so that you can review difficult concepts separately. By the end of this course, you will become a developer who is not afraid of any new concepts.
Lecture Features ✨
#1. One app Advanced Experience
I've been thinking hard about how I can teach you Android basics and practical knowledge together, and rather than creating a bunch of easy apps.I realized that it is important to experience an environment similar to the actual development of an app. That is also the environment you will face in the actual work. After implementing the core functions in the micro-micro clone coding, try to create an app that gradually develops by adding Google Maps functions, banner ads, and full-page ads functions one by one .
#2. Skill is Apply, not memorize
I have thought hard about how to convey only the essential concepts that you need. And I have come to the conclusion that no lecture can contain all the knowledge, and that it is important to apply the concepts you have learned to practice. You will learn the concepts with me, practice them right away, and acquire them. And I will constantly ask you questions about what you have learned. Review difficult concepts through the lesson notes.
#3. Sensational design Implementing the app
Apps are one of the representative front-end developments that directly meet users. Why should you use any font or any image just because it is a tutorial? Even if you are a beginner, you can implement a beautiful app. Let's learn how to implement not only the function but also the design with the image file provided only to those who complete the course.
#4. Can be used in practice Various Kotlin tips
I am afraid that you may forget Kotlin while studying Android too hard, so I have included Kotlin tip notes here and there in the lecture. If you have forgotten any Kotlin grammar, you can refer to these notes. Also, I have shared many practical tips that you can use in practice, so please check the lecture!
In Chapter 3 REAL ANDROID, you will create three apps yourself and apply the concepts you have learned.
First app. Stopwatch using threads.
In the first app, we will go over the concept of threads, which is essential not only for Android but for all programming. Then, we will go over the design update and get more familiar with Constraint Layout.
Second app. A to-do list app that uses a database.
Local database is an essential element when creating an app, and it is a concept that Android developers must learn. We will learn about the Room Database library that makes it easy to use a local database, and focus on the RecyclerView that can efficiently display a list. After you fully master the database concept through this app, you can create an app that stores your diary, or a phone book app. Or you can create a function that stores data in your first stopwatch app. At the end of this app, there is an assignment that you can update the app .
Third app. Micro-micro clone coding that attaches API communication and advertisements.
In the micro-micro clone coding, we will focus on how to use the Retrofit 2 library, which helps with Android API communication. Even if you are a programming beginner who does not know the concepts of API and HTTP communication, do not worry at all. You will learn everything in detail one by one in the pre-knowledge stage. Even if you know it in advance, think of it as a warm-up exercise before creating an app in earnest.
You will learn micro-clone coding by upgrading it sequentially from version 1, version 2, and version 3 .
In version 1, we will implement core functions of retrieving current location information and fine dust concentration.
In version 2, we will update the function to check my location on the map by linking the Google Map library and implement the fine dust concentration in the desired location.
In version 3, we will use AdMob to show banner and full-screen ads so that you can monetize your site.
And finally, we will practice packaging the app and uploading it directly to the Google Play Store . There are quite a few things to keep in mind when uploading it for the first time, but don't worry, I will explain each step in detail through video.
Frequently Asked Questions 💬
Q. I have never programmed before and I don't know Kotlin. Will that be okay?
I have been giving free lectures for several years and writing best-selling Android books, and I have been thinking about how to teach Android to you in an easy and fun way. And this lecture is the essence of my thinking. If you do not know the Kotlin language, please take the first lecture (basic grammar) and the second lecture (advanced grammar) below first. (It is free :D) You can skip the third lecture because it is related to Android development. After quickly learning Kotlin, move on to this lecture and build a solid foundation of Android.
Q. Will I be able to get a job as an Android developer if I take this course?
No, no development course will guarantee you a job. However, I will teach you how to live as a developer for life, not just a job. Think about how you want to make this app, and that app, and how fun app development is. If you become a happy developer who only programs for your whole life, you will definitely get a job. (Of course, it is natural to prepare hard according to your goal.) Because you can't beat someone who enjoys it.
This course is designed to help you learn the concepts you need in the introductory stage in the most fun way possible. After the last course, you will be able to see yourself happily imagining what kind of app you can create on your own.
Q.I've heard of Kotlin grammar, but the Android lecture is difficult!
Android programming can be said to be easy if you say it is easy, and it can be said to be infinitely difficult if you say it is difficult. If you want to make it well at the production level, you need to accumulate a lot of knowledge. However, if you feel that "Android development" itself is difficult, rather than a specific concept, then you are likely learning Android in the wrong way.
If you learn the concepts step by step, there is no concept that you cannot learn. Of course, there will be a difference in the effort and time required to learn the relatively easy TextView and the complex MVVM design pattern. However, after listening to this lecture, you will be able to develop the habit of encountering any concept, and this will become the foundation for you to become an excellent Android developer.
Q. Does Android development have a future?
Yes, Android is loved more than any other OS, accounting for 71.55% of the global market as of 2022. Cross-platform development like Flutter is also gaining attention, but most companies that prioritize UX prefer Android native app development.
Thinking about whether Android has a future is like thinking about a problem that has no answer. Try to be in the top 10% in Android. Through this course, you will solidify the concepts and polish your skills to the point where you can no longer learn anything, such as MVVM design pattern, single activity pattern, and dependency injection methods such as Dagger2. If you don't lose interest and keep your skills sharp, your future will definitely shine brightly regardless of the future of Android.
Q. Do I need to have the book?
It is not a must, but if you use it as a reference, your learning efficiency will be much higher. The lecture basically selected the three apps that are considered the most important among the examples in the book. If you want a more detailed explanation or want to make other example apps, I recommend purchasing the book and using it as a reference along with the lecture. It is not required.
