Operating System

Android

In this tutorial we will try to create a Simple Splash Screen Using Android. Android is most commonly comes installed on a variety of smartphones and tablets, and even in TV. Android is an open source so that developer find it easy to develop and expand new features. So let's do the coding...

Getting Started:

First you will have to download & install the Android Development IDE (Android Studio or Eclipse). Android Studio is an open source development feel free to develop your things.

Here's the link for the Android Studio https://developer.android.com/studio/index.html.

Layout Design

We will now create the design for the application, first locate the activity_main.xml and click text to view the script. Then copy and paste the code below.

1. <?
   
   xml version=
   
   "1.0"
   
   encoding=
   
   "utf-8"
   
   ?>
   
2. <
   
   RelativeLayout xmlns:
   
   android=
   
   "http://schemas.android.com/apk/res/android"
   
3. xmlns:
   
   app=
   
   "http://schemas.android.com/apk/res-auto"
   
4. xmlns:
   
   tools=
   
   "http://schemas.android.com/tools"
   
5. android:
   
   layout_width=
   
   "match_parent"
   
6. android:
   
   layout_height=
   
   "match_parent"
   
7. tools:
   
   context=
   
   "com.razormist.simplesplashscreen.MainActivity"
   
   >
   
8. 
   
9. <
   
   TextView
   
10. android:
    
    id=

    progress=
    
    "0"
    
24. android:
    
    layout_centerVertical=
    
    "true"
    
25. android:
    
    layout_alignParentLeft=

    layout_alignParentStart=
    
    "true"
    
    />
    
27. </
    
    RelativeLayout>
    

Android Manifest File

The Android Manifest file provides essential information about your app to the Android system in which the system must required before running the code.

1. <?

23. </
    
    manifest>
    

The Main Function

This code contains the main function of the application. This code will start running the progress bar to it target point and will load the new page at the same time. To create first locate your java file and open it, then write these block of codes.

1. package

Try to run the app and see if it worked.
