These are just some of my personal notes of videos, some websites, etc for cloud computing to share.
Cloud Computing is Useful for
1) Restoring the data that is like several years ago
2) Scaling (up or down) of the data center
3) Storing the data in every part of the world so that the network won't lose the data easily

My code: package com.thetmonaye.ucl;

import android.os.Bundle;
import android.widget.Button;
import android.widget.EditText;
import android.view.View;
public class EncoderActivity extends Activity {

super.onCreate(savedInstanceState);
setContentView(R.layout.encoder);
//Pointers to Text fields
final EditText receive_amount = (EditText) findViewById(R.id.receive_amount);
final EditText emailAddressField = (EditText) findViewById(R.id.emailAddress);
final EditText memoField = (EditText) findViewById(R.id.memo);
final EditText barcodeField = (EditText) findViewById(R.id.barcode);

}
private void generateQRCode(String data) {
// call it simply by Intent and you don't need to add library or any codes
Intent intent = new Intent("com.google.zxing.client.android.ENCODE");
intent.putExtra("ENCODE_TYPE", "TEXT_TYPE");

About Sharing function in ZXing
I found this :
Bitmap bitmap = QRCodeEncoder.encodeAsBitmap(
Message message = Message.obtain(handler, R.id.encode_succeeded);
message.obj = bitmap;
message.sendToTarget();
in the Intent.java class.
So, I somewhat understand that it sends to the "Handler" by "sendToTarget" method in handler class. Then the
In that
final void shareByEmail(String contents) {
sendEmailFromUri("mailto:", null, activity.getString(R.string.ms

interesting facts for QR

QR Generating Journey
Similar one (research from Stanford)
Step By Step: http://www.thonky.com/qr-code-tutorial/introduction/#general-overview-of-creating-a-qr-code
To make QR, we have to know :
1) The choice of characters eg. UTF8 or ISO-8859-1
2) Byte array to UTF8(but now we have to use ISO-8859-1)because UTF 8 has some non-decodable characters by ZXing library (because we are using ZXing for this app) WHY WE CHOOOSE ZXING?
3) Storage is small so, we need URL shortening technique.
===========================
QR code future is
Next QR Code Generations
1) Microsoft Tag (write details about it like detecting the areas that which QR code is scanned most, etc)
2) Dynamic QR Code (where information changes from time to time by scanning it)
3) Designer QR Codes

you might normally come across when you call the adapter from another class, they ask the class to be static

ProductDetails parsedResult=TescoJsonParser.getProductByBarcode(contents,sessionkey );
products.add(parsedResult);

I cannot use TJP.login(....,...);

QR code Generator
This is how you can make a QR code .For my case, when you can scan the QR code and you will reach to the PayPal link with the total sum of the product in it)
Firstly by using ZXing you can create by using their ZXing web link : http://zxing.appspot.com/generator
or
you can write by using QRcodeWrite class:http://zxing.org/w/docs/javadoc/com/google/zxing/qrcode/QRCodeWriter.html
http://code.google.com/p/zxing/source/browse/trunk/core/src/com/google/zxing/qrcode/QRCodeWriter.java?r=1028
But first one is very limited.

But first one is very limited.
1)Step by Step: notice the ZXing package: http://stackoverflow.com/questions/6376400/zxing-android-generate-1d-barcode
Then details inside : http://stackoverflow.com/questions/2489048/qr-code-encoding-and-decoding-using-zxing

2) image processing in ZXing library : http://code.google.com/p/zxing/source/browse/trunk/androidtest/src/com/google/zxing/client/androidtest/ZXingTestActivity.java
3) QR code writer in ZXing
http://cfsearching.blogspot.co.uk/2010/04/coldfusion-zxing-read-write-qrcode.html This is the CFC extention (not related with project)
4) Java android encoder (without using ZXing)

some new findings (BigDecimal, onResume)
BigDecimal= to get the rounded double value eg. from 2.5555555 to 2.56
onResume => I was having problems with SQlite database for not updating my scanned values into total, but I realized I was calling the total in onCreate, but not in onResume
After I call it in onResume, everything is perfect ! :)
why SQL not visible in the database?
Cos' of security issue and so we need to reboot the android

scared
I am scared sometimes just to implement and sometimes cos of that fear, my learning process is not moving at all, I am scared of the failure and really reminding me of such a failure in first year !
God, I have to keep moving !!
Give me some strength ! I will show that I am independent and I am clever !

Update of Journey
This is my 24th hour and I just had my dinner and i m reading this blog for scanning !
To search the products in your website rather than in website of Google Product search : (use this guide)
http://knol.google.com/k/alec-go/modifying-the-android-barcode-scanner/2vd5zn6va2fqd/2#
I still keep my faith to finish the step one which is multiple bar codes scan and results to show in one page.
This is for the creating barcode: http://www.java-javafx.com/2010/09/hello-world-barcode-in-java-using-zxing.html

Milestones for the journey (the map)
1) inspire by other sources until 3 pm Thursday
2) I won't be writing a library but will check how it is done
3) Read Android developer guide properly
4) 15 min break every 2 hrs
5) first step : make the multiple scanning activity and result to be shown on a page

Android ADB another ways AND SOLVED after 17 hrs
http://myhtcdesire.com/tutorials/how-to-install-the-adb-driver-on-windows
It took me total of nearly 15 hrs to debug this.
Why I took 15 hrs?
firstly, i changed to Ubuntu ! then Ubuntu is not working well and I decided to stick with Windows again.
Lesson: next time, before you switch, think carefully and try to search the bug for another 1 hr before doing that even though it is already 12 hrs passed ! because system change is very time consuming!
My another fault was that I downloaded Google driver rather than HTC Sync driver ! (I should take care of all the little steps and meanings! Rather than just overwhelmingly hurrying up for finishing this prototype! )
==================================
The Android thingy solved after installing HTC Sync ! :) omg ! it literately took me 7 days to do all those things !
http://www.htc.com/uk/help/
shit man!

Plugging in Android to PC directly not working
I alr plug in my devide and turn on the USB Debugging but it is still not working yet !
However to finish this project in 30 hrs, I need to do other things. So, I will have to ask helps from my friend in the morning later !
Some possible solutions (but not helpful) for those who got similar problem as me.

Android SDK / Eclipse set up and installation
I use Ubuntu because it is easier if you plug-in the phone to your computer and you don't need to install apache ant and ZXing library to your app !
Here is installation steps.

=======================================
This was how I did last time :

But it is not that helpful since the Eclipse in my window is not recognized my mobile phone.

Android Journey
About
This is the journey for my application which will scan the 2D / 1D barcode and link with PayPal.
I won't show what I will do but this is just my error message blogs so that I can reference again when I am lost.
Honestly, I lose an opportunity and trust from my supervisor because of my time management skills. I am not sure if I will get it again. But, I will try my best to show that I am not a loser !
This is my 30 hrs journey to achieve the trust back and to prove that I am not a loser !
