Facebook buying photo-share app Instagram for $1 billion

Facebook announces $1bn acquisition of Instagram

Facebook has announced it will be buying Instagram, the iOS and Android retro-photo app that has so far garnered more than 30 million registered users. The move however, has perplexed many, with 13-people strong Instagram recently valued at just $500 million, and currently making almost zero revenue.

Facebook’s announced acquisition of Instragram is being likened to the many ill-fated and optimistically valuated buyouts since the dotcom bubble and crash, however, for now, Facebook certainly seems to have plenty of cash to spare. Of course, both Facebook and Instagram are inherently free services, making it hard for analysts to valuate the companies, or the acquisition.

Another factor coming into play is that many Instagram users are worried about Facebook having bought their photo app, worrying that the company would change it, or use it to collect data on their activities. Facebook’s current relationship with the mass market is a love-it-or-hate-it one, though fortunately, most Instagram users are likely to already have been social network users of some sort, sharing their photos – so the deal will not be bringing too many new Facebook users.

Kevin Systrom, founder of Instagram, and Mark Zuckerberg, have both reassured users on separate blog posts that for now, Instagram will remain accessible to users in its current form. The two intend to work together to integrate Instagram into the social network. Users can still expect new features on Instagram, and, Systrom maintains, that other sharing on other social networks will continue.

Zuckerberg highlighted the importance of the acquisition for the company, saying:

We will try to learn from Instagram’s experience to build similar features into our other products. At the same time, we will try to help Instagram continue to grow by using Facebook’s strong engineering team and infrastructure.

This is an important milestone for Facebook because it’s the first time we’ve ever acquired a product and company with so many users. We don’t plan on doing many more of these, if any at all. But providing the best photo sharing experience is one reason why so many people love Facebook and we knew it would be worth bringing these two companies together.

Creating Barcode Scanner app in android


I have made an Android application using the ZXing APIs and embedded only the decoding code into my application. The input to this decoder was given through the SD card of the Android emulator.

Here are the steps:

  1. First, I created an AVD(emulator) version 4 in my Eclipse IDE with the SDcard and Camera features turned ON.

  2. Next, I have created an SDCard using the commands below in the command prompt:

    c:\>mksdcard 40M mysdcard.iso

where 40M is the size of the SD card that i have created..This will be saved in the C: drive. Note, the .iso part is important.

  1. Next, we have to mount the SD card into the emulator using the commands below in the command prompt:

     c:\>emulator -sdcard "c:\mysdcard.iso" @myavd4

Here myavd4 is the name of the emulator/android virtual device that I created in step 1. The ‘@’ sign before the avd name is important too.

Keep the emulator running all the time..If it gets closed, we have to redo the above 3 steps.

  1. We can push the QR code or other code images that we have to this SD card mounted on our emulator by using the commands below in the command prompt:

    c:\>adb push "c:\myqrcode.png" /sdcard
  2. Next, in the Eclipse IDE, start a new android project. The code below should be pasted in the QRDecoder.java file of our project.

    package com.example.palani;
    import android.app.Activity;
    import android.content.Intent;
    import android.graphics.Bitmap;
    import android.graphics.BitmapFactory;
    import android.net.Uri;
    import android.os.Bundle;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.TextView;
    import com.google.zxing.BarcodeFormat;
    import com.google.zxing.BinaryBitmap;
    import com.google.zxing.ChecksumException;
    import com.google.zxing.FormatException;
    import com.google.zxing.LuminanceSource;
    import com.google.zxing.MultiFormatReader;
    import com.google.zxing.NotFoundException;
    import com.google.zxing.Reader;
    import com.google.zxing.Result;
    import com.google.zxing.ResultPoint;
    import com.google.zxing.client.androidtest.RGBLuminanceSource;
    import com.google.zxing.common.HybridBinarizer;
    public class QRDecoder extends Activity implements OnClickListener {
        public static class Global
            public static String text=null;
        public void onCreate(Bundle savedInstanceState) {
            Bitmap bMap = BitmapFactory.decodeFile("/sdcard/myqrcode.png");
            TextView textv = (TextView) findViewById(R.id.mytext);
            View webbutton=findViewById(R.id.webbutton);
            LuminanceSource source = new RGBLuminanceSource(bMap);
            BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
            Reader reader = new MultiFormatReader();
            try {
                 Result result = reader.decode(bitmap);
                 Global.text = result.getText();
                    byte[] rawBytes = result.getRawBytes();
                    BarcodeFormat format = result.getBarcodeFormat();
                    ResultPoint[] points = result.getResultPoints();
            } catch (NotFoundException e) {
                // TODO Auto-generated catch block
            } catch (ChecksumException e) {
                // TODO Auto-generated catch block
            } catch (FormatException e) {
                // TODO Auto-generated catch block


        public void onClick(View v) {
            Uri uri = Uri.parse(Global.text);
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);


  3. Next I downloaded the ZXing Source Code (ZXing-1.6.zip) from the below link.


Then, extract this and navigate to D:\zxing-1.6\core\src\com

copy the com folder and paste it in our package in Eclipse.

(Note, right click on the package of our project and paste…if it asks for replacing the existing folder, select yes)

  1. Next, copy and paste the below code in the res/layout/main.xml file

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"






  2. Next, copy and paste the below code in the res/values/strings.xml file

    <?xml version="1.0" encoding="utf-8"?>
        <string name="hello">Hello World, QRDecoder!</string>
        <string name="app_name">QRDecoder</string>
        <string name="continue_label">Click below to load the URL!!</string>
        <string name="web_button">Load the URL!!</string>
        <string name="decode_label">Decoded URL</string>

  3. Next, copy and paste the below code in the res/values/color.xml file, if it does not exist, create one.

    <?xml version="1.0" encoding="utf-8"?>
    <color name="mbackground1">#7cfc00</color>
    <color name="mbackground2">#ffff00</color>
    <color name="mytextcolor">#d2691e</color>
  4. Next, copy and paste the below code in the manifest file after the opening tag


    <uses-permission android:name="android.permission.INTERNET" />
      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
      <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />      
  5. So, these above steps done…our application is ready. Now, u can run the application and it will give u the decoded result of the input image we have given.

  6. In order to change the input, push another file to SD card using the command below in the command prompt

    c:\>adb push "c:\image2.png" /sdcard

and change the input in our QRDecoder.java to reflect the same

    Bitmap bMap = BitmapFactory.decodeFile("/sdcard/image.png");

the inputs can be any format like QRCode, Barcode, etc….the types of image can be bmp, jpg or png.

I used the below website for generating the QR codes for test purpose




Thanks and I would like to mention the point that I am just a beginner in android and mobile application development and sorry for any mistakes that I might have done…
