In this tutorial, we will learn How to Convert a Website into an Android Application using Android Studio.
If you do not know anything about Android Studio yet, Don’t worry.We will start everything from scratch.
This is how the website looks like:
And the Android app, we developed using Android Studio looks like:
NOTE: If you downloaded Android Studio and already installed in your system then you can skip the part and Go to direct the coding part.
If notDownload Android Studio:
Google provides Android Studio for the Windows, Mac OS X, and Linux platforms. You can download this software from the Android Studio homepage.
Before downloading Android Studio, make sure your platform meets one of the following requirements:**Windows OS**Microsoft Windows 7/8/10 (32-bit or 64-bit)2 GB RAM minimum, 8 GB RAM recommended2 GB of available disk space minimum, 4 GB Recommended (500 MB for IDE + 1.5 GB for Android SDK and emulator system image)1280 x 800 minimum screen resolutionFor accelerated emulator: 64-bit operating system and Intel processor with support for Intel VT-x, Intel EM64T (Intel 64), and Execute Disable (XD) Bit functionality
**Mac OS**Mac OS X 10.8.5 or higher, up to 10.11.4 (El Capitan)2 GB RAM minimum, 8 GB RAM recommended2 GB of available disk space minimum, 4 GB Recommended (500 MB for IDE + 1.5 GB for Android SDK and emulator system image)1280 x 800 minimum screen resolutionJDK 6

To complete your installation, leave the Start Android Studio box checked and click Finish.

Android Studio presents a splash screen when it starts running:
If you’re like me and don’t have a previously installed version, you can just keep the default setting and click OK.
Figure 9. Validate your Android SDK and development environment setup
When you click Next, the setup wizard invites you to select an installation type for your SDK components. For now, I recommend you keep the default standard setting.
Figure 10. Choose an installation type
Figure 11. Review settings
The wizard will download and unzip various components. Click Show Details if you want to see more information about the archives being downloaded and their contents.

Your options are to either put up with the slow emulator or use an Android device to speed up development. I’ll discuss the latter option later in the tutorial.
Finally, click Finish to complete the wizard. You should see the Welcome to Android Studio dialog box:
Figure 14. Welcome to Android Studio
You’ve installed and configured Android Studio and created a project for your first Android Studio mobile app; now you’re ready to build your Android application. In Android Studio, this means populating your new project with Java source code and resource files.
From our setup so far, you should still have Android Studio running with the Welcome to Android Studio dialog box. From here, click Start a new Android Studio project. Android Studio will respond with the Create New Project dialog box shown in Figure.
Figure 15. Create a new project
Figure 16. Select your target device categories
Click Next, and you will be given the opportunity to choose a template for your app’s main activity. For now, we’ll stick with Empty Activity. Select this template and click Next.
Next, you’ll customize the activity:
Enter W2A as the activity name and main as the layout name, and click Finish to complete this step. Android Studio will respond that it is creating the project, then take you to the project workspace.
Figure 19. Android Studio workspace
The project window is organized into a tree whose main branches are App and Gradle Scripts. The App branch is further organized into manifests, java, and res subbranches:
The Gradle Scripts branch identifies various .gradle (such as build.gradle) and .properties (such as local.properties) files that are used by the Gradle-based build system.
Add a webView to your activity as shown in the picture below.

Add a launching activity to App: (It looks nice)
Launching Activity
**SplashActivity.java**
package com.vinaysomawat.careerhigh;
_/*** Created by Vinay Somawat on 10-01-2019.*/_import android.content.Intent;import android.os.Bundle;import android.support.annotation.Nullable;import android.support.v7.app.AppCompatActivity;
public class SplashActivity extends AppCompatActivity {
@Override
**protected void** onCreate(@Nullable Bundle savedInstanceState) {
**super**.onCreate(savedInstanceState);
Intent intent = **new** Intent(**this**, MainActivity.**class**);
startActivity(intent);
finish();
}
}
And add some code it values/styles.xml
<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar"><item name="android:windowBackground">@drawable/background</item></style>
create a drawable/background.xml
file:
<?xml version="1.0" encoding="utf-8"_?>_<layer-list xmlns:android="http://schemas.android.com/apk/res/android"><item android:drawable="@color/colorPrimary" />
<**item**\>
<**bitmap android:src="@drawable/logo2"
android:gravity="center"** />
</**item**\>
</layer-list>
make sure you add a sample image to drawable
folder to display in launching activity.
OUTPUT:
Now run your android app, and you will see the following result
If you got stuck somewhere
Or use the following command:
command-line
>git clone https://github.com/vinaysomawat/CareerHigh-App
And share your Android App with your friends.
