Android Course Build 3 Applications from Scratch with Java (Udemy.com)

Master the Art of Android App Development with Java by Building Real-World Applications

Created by: Vijay Kumar

Last updated July 2023

Our take

Based on the ratings of 146 students, a sample of their written reviews and the syllabus, as the course stood in July 2023. No course pays to be reviewed.

Vijay Kumar's course is a short project walkthrough, not a full Android bootcamp. It runs about 2.6 hours across 14 lectures and four sections, and it builds three small apps: a word-guessing game, a simple calculator and a long story reader. More than 52,000 students have enrolled. It is labeled beginner, but the requirements ask for Java basics and object-oriented concepts, so it really suits people who already know some Java and want to see it turned into working apps.

Reviews split along a clear line. Of 146 ratings, 108 are four or five stars, and happy students talk about steps that are easy to follow, practical projects, and picking up layouts, event handling and the activity lifecycle. The low-star reviews we can see say the opposite: the code is not explained, the flow of the app is hard to follow, and the instructor speaks too fast in English that is hard to understand. One reviewer also found the lectures out of order and missing setup help. Another 27 people gave three stars.

Value depends on expectations. The last update was July 2023, and there are no quizzes or coding exercises to practice with. The calculator is a single 31 minute lecture, which is thin. If you have Java basics and want quick, hands-on practice, it is a decent afternoon. If you are starting from zero, or need slow explanations of each line, pick something longer and more patient.

Best forPeople who know basic Java and want a quick, hands-on first look at building three small Android apps.
Skip it ifYou are a true beginner who needs each line of code explained slowly, or want a long, in-depth Android course.

Pros

  • Three finished apps in about 2.6 hours, so it fits into a weekend
  • Step-by-step walkthroughs that happy reviewers call easy to follow
  • Covers layouts, event handling and the activity lifecycle through real projects
  • Over 52,000 students enrolled and 108 of 146 ratings are four or five stars

Cons

  • Fast, hard-to-follow English and thin explanations of the code, per the low-star reviews
  • Labeled beginner, but the requirements expect Java and OOP knowledge first
  • No quizzes or coding exercises, and the last update was July 2023
I really appreciated the way the instructor walked through each step of building the applications, especially in Lecture 1 of the Guess The Word application.

Labeled beginner, but it expects Java basics and OOP first, so it fits early-stage Java learners, not total newcomers.
