Start activity once notification clicked

In the exercise "Generate Notification with sound when alarm received", a browse opened and load a specified url once user click on the notification. We can also pass intent to start activity to notification, to start activity once user click on the notification.

Start activity once notification clicked

Modify AlarmReceiver.java in the exercise "Generate Notification with sound when alarm received", pass Intent(context, DoSomething.class) to PendingIntent.getActivity(...).
package com.example.androiddatepicker;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import android.widget.Toast;

public class AlarmReceiver extends BroadcastReceiver {
 
 private static final int MY_NOTIFICATION_ID=1;
 NotificationManager notificationManager;
 Notification myNotification;

 @Override
 public void onReceive(Context context, Intent intent) {
  Toast.makeText(context, "Alarm received!", Toast.LENGTH_LONG).show();

     Intent myIntent = new Intent(context, DoSomething.class);
     PendingIntent pendingIntent = PendingIntent.getActivity(
            context, 
            0, 
            myIntent, 
            Intent.FLAG_ACTIVITY_NEW_TASK);
     
     myNotification = new NotificationCompat.Builder(context)
       .setContentTitle("Exercise of Notification!")
       .setContentText("Do Something...")
       .setTicker("Notification!")
       .setWhen(System.currentTimeMillis())
       .setContentIntent(pendingIntent)
       .setDefaults(Notification.DEFAULT_SOUND)
       .setAutoCancel(true)
       .setSmallIcon(R.drawable.ic_launcher)
       .build();
     
     notificationManager = 
       (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
     notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
 }

}


Create DoSomething.java, it will be started once user click the notification.
package com.example.androiddatepicker;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.Toast;

public class DoSomething extends Activity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  ImageView image = new ImageView(this);
  image.setImageDrawable(getResources().getDrawable(R.drawable.ic_launcher));
  setContentView(image);
  Toast.makeText(getApplicationContext(), 
    "Do Something NOW", 
    Toast.LENGTH_LONG).show();
 }

}


Modify AndroidManifest.xml to add <activity> of "DoSomething".
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androiddatepicker"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.androiddatepicker.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.example.androiddatepicker.DoSomething"
            android:label="@string/app_name" >
        </activity>
        <receiver android:name=".AlarmReceiver" android:process=":remote" />
    </application>

</manifest>
