Build A Professional Application

Welcome to our new tutorial on Android Studio . On this tutorial we are going to build an application with all features and every thing integrated like splash screen , notification system , in-build update checker , custom off-line notification , etc ...

• Set up android studio in your windows and linux computers

Watch the video and follow me :

• Build a new Android Studio Project .
• I am using the package name as com.techmobs.app here you can change it to any other name that you like , but be care full while copy pasting the codes don't make the package name on each files wrong be sure that you use the same package name every where .
• Choose the Navigation Drawer Activity .
• After gradle build up we can move on to the AndroidManifest.xml file
• Open AndroidManifest.xml file and select the entire codes and replace it with the code bellow . Don't make package name error , be careful .

	<?xml version="1.0" encoding="utf-8"?>
	<manifest xmlns:android="http://schemas.android.com/apk/res/android"
	package="com.techmobs.app">
	<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

• Now go through the java parts again to change the links , name , email , etc 
• First of all the MainActivity.java file , open it and replace the website urls with your website url . Watch video for more clarification .
• Like that the splash.java file replace the facebook , google+ , twitter links .
• Now the UpdateService.java "https://vishnutechmobs.github.io/update-link.html" this is the link link which is checked when the application opens . The content in line

boolean resp = response.contains("1.0"); is compared that here is 1.0 . 

My link is a github page i prefer you to use github for this and when the contents in the link and the line are same no update will appear but if the any one value changes then the update dialog box comes .

The update dialog box is file:///android_asset/update.html which is the update.html file that we created in the Assets folder . You can edit it and keep your name instead of my name .

Now UpdateDialog.java , If update box appears then we go to this link if we click Download "https://vishnutechmobs.github.io/update.html" , change it with a link that can be updated link a blog post etc ... Download my 2 test applications and check them then you will understand .

If you guys don't want update checker just don't add the UpdateDialog.java and UpdateService.java file and remove this line from MainAvtivity.java .

 

Intent intent =newIntent(MainActivity.this,UpdateService.class)
startService(intent);

• Now watch the video and clarify if more doubts are there .
• Build your apk and then you will get your application .

• Set up android studio in your windows and linux computers
