If one knows android development, not only will you be having a stable and sound career but can unleash you hidden talents as a developer.

Course Overview

if you take this course (which you should!!) know that you are on your way to build a solid and stable foundation of Android Development, Android Studio and object-oriented Java Programming. You don’t need to spend years and years on learning, with me you can learn in 6 weeks!!!! YES! That is right, in six weeks you’ll be able to make and develop your own app and you never know, you could have it running at the app store and be an instant hit!

I have designed this course assuming your goal is to become an Android developer and you don't have any background in programming before. This course is completely hands On and you will be making your first APP from the second lecture. I will also share with you the developer forums and the resources that you can use if you face any challenges while building your apps.

Once you buy this course, you have LIFE TIME ACCESS to it. You can always refer back to any section that you want to revise and move along. Every section of ours has been built to test your ability. You not only get the content but also are given quizzes and assignments to ensure that what you have learnt is retained and you fully understand the content. (Don’t worry, we won’t scold you if you have some problem, we will be throughout). We assure you, with us you’ll be an android developer in no time!


Our course is designed specifically for people who have ZERO prior experience in programming and have never even programmed a single thing before. It doesn’t matter if you have absolutely no idea about the basics (that is why we are here!), we will teach you everything that you need to know about developing and programming in just 6 weeks. All you need is loads of passion, a hint of dedication, an internet connection and a laptop or PC. It’s that easy!!

Why take this course?

Obviously once you’ve made up your mind to become an expert developer, you will question the fact that why should you choose me? The answer is because I am passionate about android, I breathe, live and eat android! I have been in the industry for more than a decade and with my knowledge and experience I can teach you with hands on experience. I have a decade of experience in our bags of solid programming experience along with five years of application development experience. My experience can be measured by us having over fifty applications and games (developed by us) on not only the Android Google Play but also on the Apple App Store.

Who is the target audience?
  • Anyone with no programming experience before and wanted to make Apps
  • Anyone who wants to learn programming: JAVA is one of the best language to start with.
  • Anyone who wants to make a career as Android developer.
  • Anyone who wants to understand how computers work: Learning to code is so much more than being able to make apps - knowing how computers work is your key to a hugely powerful world

The basic building block for user interface is a View object which is created from the View class and occupies a rectangular area on the screen and is responsible for drawing and event handling.There are different types of views:

  1. TextView : TextView is a view that contains text.
  2. Button: Button is a view that has text in it.
  3. ImageView:: View that contains image is called as image view.

What is the difference between:

  • px
  • dip
  • dp
  • sp

px: Pixels - corresponds to actual pixels on the screen.

dp: Density-independent Pixels - an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. Note: The compiler accepts both "dip" and "dp", though "dp" is more consistent with "sp

sp: Scale-independent Pixels - this is like the dp unit, but it is also scaled by the user's font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and user's preference.

Moreover you should have clear understanding about the following concepts:

Screen size: Actual physical size, measured as the screen's diagonal. For simplicity, Android groups all actual screen sizes into four generalized sizes: small, normal, large, and extra large.

Screen density: The quantity of pixels within a physical area of the screen; usually referred to as dpi (dots per inch). For example, a "low" density screen has fewer pixels within a given physical area, compared to a "normal" or "high" density screen. For simplicity, Android groups all actual screen densities into four generalized densities: low, medium, high, and extra high.

Orientation: The orientation of the screen from the user's point of view. This is either landscape or portrait, meaning that the screen's aspect ratio is either wide or tall, respectively. Be aware that not only do different devices operate in different orientations by default, but the orientation can change at runtime when the user rotates the device.

Resolution: The total number of physical pixels on a screen. When adding support for multiple screens, applications do not work directly with resolution; applications should be concerned only with screen size and density, as specified by the generalized size and density groups.

Density-independent pixel (dp): A virtual pixel unit that you should use when defining UI layout, to express layout dimensions or position in a density-independent way. The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. The conversion of dp units to screen pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels. You should always use dp units when defining your application's UI, to ensure proper display of your UI on screens with different densities.
