OBTAINING THE REQUIRED TOOLS

Now that you know what Android is and what its feature set contains, you are probably anxious to get your hands dirty and start writing some application! Before you write your first app,however , you need to download the required tools.

For Android development , you can use a Mac,Windows PC,or a Linux machine. You can freely download all the necessary tools. Most of the examples provided in the blog are written to work on Android Studio. For this Blog, i am using a Windows 10 computer to demonstrate all the code samples.If you are using a Mac or Linux computer , the screenshots look similar. Some minor differences might be present,but you should be able to follow along without problems.

Let the fun begin !

NOTE:-

The Android Studio makes use of the Java SE Development Kit (JDK) . If Your computer does not have JDK installed, yous should by Downloading it from https://www.oracle.com/technetwork/java/javase/downloads/jdk13-downloads-5672538.html and installing it prior to moving to the next section.

The Material theme has a much more modern and clean look to it. There are two versions of the Material theme available to Android developers : Material Light and Material Dark , Either of these themes can be applied from the AndroidManifest.xml To apply one of the Material themes to an activity , simply modify the <Application> element in the AndroidManifest.xml file by changing the default android:theme attribute.

Using Code Completion

Code completion is an invaluable tool that shows you contextual options for completing the piece of code that you are trying to write. For example, in the editor tab for the MainActivity.js file, locate the line that reads. setContentView(R.layout.activity_main); Place your cursor after this line and press the Enter Key . On the new line , type the letter R , and then type a period, as shown here: R. Android Studio Code Completion should display a list of values that you could use to try to complete the code statement. Figure shows what this list might look like . this is important if you are not entirely sure of the spelling of a method call or how to identify the different method signatures. NOTE if the code completion window does not open , press Ctrl + Space to force it to open. This is the same key combination used in some other IDEs for their versions of the code complet...
