Android Mobile App Development for Beginners with Android Studio

Its quite interesting to know that Mobile Application development is not as difficult as some may think. In fact, learning mobile app development may even be easier than developing apps for desktops.

There are two reasons for this:
  1. In mobile app development, you could see the result of development effort almost immediately as you would be testing in an emulator from time to time
  2. Additionally, for mobile applications, you could easily find the market as soon as you get your app in an app store.
  3. Mobile app development software are mostly free
  4. Finally, you can start mobile app development with little or now knowledge of programming.




So lets get started!

First I would like to let you know that beginning this week, I would start a series of easy lessons on Android Mobile Application development for my readers who really want to learn mobile application development.
This is how the lessons would be structured:
  • Every week, there would be two classes. The first class which would be available in the beginning of the week is a lesson. The second class which would be available at the second half of the week is an quiz
  • The next week's lesson would follow from the previous week's lesson and we would progress
  • Beginning from February, each lesson would be accompanied by a video tutorial as well.
  • Every student is expected to complete the lesson and be sure they would be easy lessons, yes, the difficulty level would be 'easy'
  • Each student that completes the quiz, in a short time before the weekend could request for an additional personalized quiz/lesson that would be provided before the beginning of the previous week.

Today's Task: Download and Install Android Studio
Step 1: Visit https://developer.android.com/studio/index.html and download Android Studio for windows
If you are on mac, download from this link: https://dl.google.com/dl/android/studio/install/3.0.1.0/android-studio-ide-171.4443003-mac.dmg

Step 2: Run the installation



Step 3: Open Android Studio to complete the installation. The first time you attempt you will see a screen like the one below.


Make sure the Android SDK, Android Virtual Device and Performance is selected and click on Next to continue the installation. It takes a while depending on the speed of your internet connection.

Step 4: Open Android studio and Start a New Application.

Step 5: Click on Start a Net Project (the first item)

Step 6: Give the application a name(I used FirstApp). You can leave every other thing the way it is. Then click on Next

Step 7: For the next screens, continue to click on next until you get to the last window. Then you can click on Finish.The following screen is displayed



Step 8: You then need to wait for a while for Android Studio to set up your new Project. When the IDE opens, you may see an error message that prompts you to install missing platforms. Go ahead to installs. At the end of the installation, if you have followed the procedure correctly, then you will have the screen shown below.

If this is the case, then you can buy a bottle of beer and celebrate!

And be sure that if you continue like this in the next few months, you will be able to develop a very good mobile app.

If you have any challenges getting to this point, let me know in the comment box below. And see you in the next class where we would discuss 'The Structure of the Android Mobile Application'.
