Simple animation to your android project

In here I explain how to add a simple animation to your android project. At final you will be able to see simple flashing set of images at your login screen.

1. Create xml file named "flag.xml" under drawable folder

2. Add following code to your flag.xml

<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/flaganim"
  android:oneshot="false">
  <item android:drawable="@drawable/sliit" android:duration="4000" />
  <item android:drawable="@drawable/mlb" android:duration="4000" />
  <item android:drawable="@drawable/logo" android:duration="4000" />
  <item android:drawable="@drawable/metro" android:duration="4000" />
  <item android:drawable="@drawable/convacation" android:duration="4000" />
   <item android:drawable="@drawable/matara" android:duration="4000" />
</animation-list>

3. To your main activity add following code

  final ImageView splashImageView = (ImageView) findViewById(R.id.imageView2);

  splashImageView.setBackgroundResource(R.drawable.flag);
  final AnimationDrawable frameAnimation = (AnimationDrawable)splashImageView.getBackground();
  
  splashImageView.post(new Runnable(){
  @Override
   public void run()
  {
  frameAnimation.start();              
  }          
  });

4. Run the project

That's All :)

Notification Handling

In this tutorial I will explain how to add notifications to your android project

1. Create a project name “notifications”

2. Create a class “Notification Handling” and layout “home”

3. Add below code to view notices button 

Notification Handling.java

 String ns=Context.NOTIFICATION_SERVICE;

 NotificationManager snortificationManager=(NotificationManager) getSystemService(ns);

 int icon=R.drawable.mynotify;

 CharSequence tickerText="Drag Here To View Notices";

 long when=System.currentTimeMillis();

 Context context=getApplicationContext();

 CharSequence contentTitle="New Notifications";

 CharSequence contentText="You Have Received New Notices";

 Intent notifyIntent= new Intent(Home.this,ViewCourses.class);

 PendingIntent contentIntent =PendingIntent.getActivity(Home.this, 0, notifyIntent, 0);

 Notification notification=new Notification(icon,tickerText,when);   notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);

 snortificationManager.notify(10,notification);

home.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

 android:layout_width="match_parent"

 android:layout_height="match_parent"

 android:background="@drawable/backgrounddd"

 android:orientation="vertical" >

 <Button

 android:id="@+id/imageButtonn"

 android:layout_width="wrap_content"

 android:layout_height="wrap_content"

 android:layout_alignParentLeft="true"

 android:layout_alignParentRight="true"

 android:layout_below="@+id/textView5"

 android:background="@drawable/button_shape_2"

 android:minHeight="30dp"

 android:text="View Notices" />

4. Import below classes to your Notification_handling.java

Import import android.app.Notification;

import android.app.NotificationManager;

5. Run the Application click "View Notices" button

That's All  :)

That's All :) :)
