Build your first Hello World Android app Tutorial 2

We continue our series on Android apps. This post will help you create your first basic  ’Hello Word’ Android app and run it.  This app will display “Hello World ! ” on your device/emulator. It is the simplest program available in any programming language. It is  traditionally used to help beginners with the most basic syntax of Android development . It is also used to verify that the environment you have set up on your system for Android development is operating correctly.
For developing an Android app on your PC or laptop, you need to set up an Android development environment on your computer. You can do that by following our first post in the series here.

Once you set up your android development environment. Follow these simple steps:

Step 1 : Open Eclipse from ADT bundle –>Eclipse folder.




While opening Eclipse, a pop-up window will ask for a workspace folder. Select the folder in your hard drive where you would like to store your Android application projects.

Step 2 : Create a new Android application project by selecting File –> New –> Android Application Project.


Step 3 : Fill in your Android project details

Give  the application a name such as ” My First Android App “.  This name will be displayed in the app menu once you install this app on an Android device or an emulator. Name the project “First App” and type in a  package name where you would like to store all your Java files.  Make sure that  you select a unique package name (example: startup.village or your firstname.lastname) and type it in lower case keys to adhere with the coding standards.


Step 4 : Locate the project folder and expand it 

Eclipse will now show the user interface of your app (Graphical Layout of activity_mail.xml) with a ” Hello World ” TextView widget right in the middle of it by default.  You can also see a newly created project folder in the package explorer window with the given project name. Expand that folder to view files.


Your Hello World App is almost ready to run but before going ahead let us take a look at the folders and files in your projects folder for a better understanding.


src  : The ‘src’ folder  or the source folder contains your package name and Java files are stored in it.
res  :  The “res” folder or the resource folder stores all your  user interface design xml files, images,sound, videos etc. that will be used in your app.
R.java  :  You can find R.java file in the gen folder. R.java is where you have access to anything you have in your resources folder.
AndroidManifest.xml : Android manifest contains essential information about the application, information the system must have before it can run any of the application’s code.


Step  5  : Run your app 

Run your app for the first time by clicking on the ” Run ” button and select Run As –> Android Application.  The Android virtual device (AVD/emulator) will automatically pop up and run the application in it.


In case you have not set up an Android device , you can do it by following our previous article. You can also connect your “USB Debugging” enabled android smartphone/tablet and install this app in it.


Please watch this space for more Android development tutorials. If you have any doubts regarding this post, you can post your queries in the comment section below and we will be happy to help you.

Nokia Phone Secrets

First things first, Nokia is a worldwide Corporation which owns 36% of the market share. So no doubt alot of you own a Nokia mobile, whether it be CDMA or GSM.

CDMA : Is a phone which does not need a sim card to run, it just stores everything on the phone.
GSM : Is a phone which has a SIM card (like Vodafone)

There are several codes that you can use on Nokia's, i will run through these in this article.
(Stand-by mode is the main/home screen which displays your battery charge and signal)

----------------------------------------------------------------------------------------------


----------------------------------------------------------------------------------------------

1. Service Programming Menu - *3001#12345#

(NOTE: The Service Programming Menu only works on CDMA phones)
This menu is the mother of all Nokia codes, you can edit your phone like mad here, most of these menus your service provider probably doesn't want you to have the ability to do. So here we go.

On stand-by mode, type in *3001#12345# and wait a few seconds for it to load up. Once the screen comes up you will have several options, all with different functions. (NOTE: this menu differs on different phones.)

1. NAM 1
2. Change SPC
3. Security
4. Server addr.
5. SW version
6. Serial number
7. Programmed
8. Field test

----------------------------------------------------------------------------------------------

1. NAM 1 (* means explained below)

This is the most useful menu your phone has, it allows you to edit the heck out of your phone! inside NAM 1 there are these different menus:

Own number*
Mobile ID number
A-key code
Alpha tag*
Emergency*
Service No.
CDMA settings
NAM status

Own number:
Self explanitory, but if you want a new number then this is where you want to go. Just enter this menu followed by the SPC (see Change SPC) then change your number. This DOES work, but the new phone number you want must not already be in use.

Alpha tag:
You know on the standby screen, there's the "Vodafone" or "Telecom" or "T-Mobile" that appears? well now you can get rid of that annoying tag. Change this to whatever you please, just to make your phone more personalised.

Emergency:
This menu is basically a menu which displays all the numbers that will divert to the emergency number of your area. For example, if you live in USA and your emergency number is 911, in this menu there will be "911","811", "991" and the obvious numbers that you may type in while trying to reach 911. It's smart not to mess with these, because you never know when you'll be in an emergency. There should be some free slots so why not add in a couple more numbers that you want to divert to your emergency?
Some people think "Wow! emergency number! that calls for free, so maybe if i put in my friends number then it will give me free calls to him/her!" WRONG. This menu can NOT give you free calls. If you were to put in your friends number, then whenever you called them you would end up calling the emergency line - as that's what you're diverted to! REMEMBER THIS!

----------------------------------------------------------------------------------------------

2. Change SPC

The SPC is the Service Programming Code. This code is rather hard to come across, as the service providers try to hide it from the public so they can't access these places on their phones. But luckily enough if you live in New Zealand then here is the code :)

147359 - Is the default code that will let you into 'almost' anything
665*** - Is the 'master' code, that will let you into anything you like.

(The *** is the last 3 digits of your Nokia model, for example: If your Nokia was model number '8734', then your master code will be '665734'. The 665 is the default number for the Nokia company.)

So, this menu just means you can change the code. NOTE: Some mean stores when you buy the phone tend to access this menu and change it so that the owner can't access it :( that is not always the case though, so try it out!

----------------------------------------------------------------------------------------------

3. Security

This menu just shows you the security code that is installed on your phone, couldn't be more bland.
FUN TRICK: why not have a look at your friend/work mates' phone and access this menu, you could then see their security code or change it just for fun :) But we're nice people and that's naughty, so we arn't going to do that are we..

----------------------------------------------------------------------------------------------

4. Server addr.

This is the server address of your service provider. Nothing you can do here.

----------------------------------------------------------------------------------------------

5. SW version

Once again, another menu with not alot of meaning. All you can do in here is check out when your phone was activated, and what version software it is running. This can also be accessed on GSM phones (see below)

----------------------------------------------------------------------------------------------

6. Serial number

This is your serial number. DUH.
It would be a wise idea to jot this down somewhere safe, because this could be useful. If your phone was ever lost or stolen then you could contact your service provider and give them this code. This would let them shut the phone down so that your robber couldn't use your phone - or access anything on it for that matter.

----------------------------------------------------------------------------------------------

7. Programmed

This is just a menu that you can only access once, which lets you type in when your phone was programmed.

Seem like the menus are getting lamer? Wait for the next one..

----------------------------------------------------------------------------------------------

8. Field Test

This is an option which is quite cool really. Go into Field test and change "Disabled" to "Enabled". Then get out of the whole service programming menu.
Now, turn your phone off, and back on again.
Once it loads up go to your normal menu and scroll to the bottom. Notice you have just added a new menu to your phone? It is called Net Monitor.
Net Monitor speaks for itself, with this option you can monitor your network to a small extent.
Enter Net Monitor and it will prompt you with "Group/display:" enter in 3101 and press OK.
It should take you back to your standby screen, nothing will have changed. But wait a few seconds and then all these numbers will appear on your screen. What do they mean?

There is only one number you can really understand in this menu. This number is located as the third number down, it will say something like "-50" (the 50 can range anywhere from 10 to 99). This is how strong the signal is.

For example : If your phone displayed -10 here then it's telling you that your neighbour is a cell site and your signal is really really good.

If your phone displayed -90 then it's basically telling you that where you live or where you are at that certain time has really bad signal.

You will notice that as you get closer/further away to a cell site this number will grow or decrease.

----------------------------------------------------------------------------------------------

That sums up the Service Programming Menu, and the extra things your service provider doesn't want you doing :}

There are many other codes that you can use on CDMA phones, just search around for them.

Extra Codes:

*#66767# - This code when spelt out is "NO-SMS", so shouldn't that mean no texting? well, yes. If you enter this code in on your phone then you will no longer have the ability to "Create Message" or "Reply". If you're really mean then enter it on your brother or sisters phone, that's sure to give you some laughs. You can bring them back again by re-entering the code.

*#639# - This brings you to the menu which just re-programs your phone faster. I wouldn't reccomend you doing this if you value your phone.

*#7780# - This takes you to a menu which says "Restore Factory Settings", i think you understand what will happen if you press yes :p

GSM Code:

This is the only GSM code i know from the top of my head, just search around for more as I'm sure they're out there.

*#0000# - This is probably the most useless code you can find, but anyway it just gives you information on when your phone was activated. If your phone was sent in for repair, then this date will have changed to the date when it was fixed.

make an Android app on your computer - Tutorial 1

We are launching a new series where we will teach you everything that you need to know about making an Android app. It does not matter if you cannot afford a fancy Android tablet or a smartphone. We begin this series with a small tutorial on how to make an app using your laptop. All Android development tools are available on the web for free. You can start developing apps for Androids by following some simple steps described below:

System Requirement 

Development for Android can be done on any reasonably-sized computer with Windows or Linux. For a decent experience, a computer or laptop with the following configuration is recommended: a 2.0 GHz CPU with at least 3 GB of RAM and 1 GB of available hard disk space.  You don’t require an Android device to start developing as you can test your app in the Android virtual device that comes with the Android Development Tools Bundle.


Software Requirements 

Android Development Tools Bundle (contains Eclispse,  Android SDK, Device Emulator)
Java Development Kit or JDK (6 or 7)
Follow the steps below to set up an Android development environment:

Step 1 : Download JDK from the following Link



Now Install Java using the downloaded “jdk-7-windows-i586″  just like you install any other software.

Step 2 : Download ADT Bundle from the following link



Step 3 : Extract ADT bundle to a specific folder

Once you download the ADT Bundle , you will get a zip file named “adt-bundle-windows-x86″ which is roughly 400 MB in size.
Extract this zip file to any specific folder where you would like to set up your Android development tools.
Open that  folder to find two folders “Eclispe” and “sdk”. Open the eclipse folder.




Step 4 : Open Eclipse

In Eclipse folder click on the Eclipse icon.


Step 5 : Select your projects folder

Now the Android development tools will launch eclipse for the first time. It will take a while for it to set up until you reach the following screen:


Select the folder where you want your Android development projects to be stored and click OK.  Eclipse will be loaded and you are all set to start developing apps for Android. To start an Android app development project select  File –> New –> Android Application Project. 


Step 6 : Create an Android Virtual Device (AVD)

In case you don’t have an Android Device , you can easily create a virtual device by selecting Window –> AVD Manager –> New


In the following window, Give a name to your virtual device and Select 4.0 “Nexus S ” for device and Android 4.2 as target and click OK


Your virtual device is ready now and your Android development project can be tested. The Virtual device will pop up automatically when you run your project for testing. Be patient as it may take up to 5 mins for the device to load entirely.

Now you are all set to start developing your own Android apps. If you have any doubts regarding this post or get stuck while trying to set up an android development environment, you can post your queries in the comment section below and we will be happy to help you. we will post the second tutorial in the coming week. keep checking.
Happy Coding!
