Intern Story: Begining Android Development (first hand experience)

Before starting developing Android apps, the development environment is set up. I found it a bit of a hassle, but once it sets up, it works really well. Eclipse is the IDE that I use. I am following the Android training from developer.android.com. Android applications are built in Java and uses XML. The first day is stressful as the vocabulary from the Java and the Android SDK is completely new to me. It takes time to understand and get acquainted with the new vocabulary.

The XML part is straight forward, but linking things like links in websites is a fiddly job. As we can make html pages in website for each page in an Android application we make an Activity. And we can link between activities like we can do in website, which can be done by intent. Intent is an intention to do an action. It is a message from an application saying it wants to perform an action. It lets the applications to interact with each activity and share data. This is a useful feature that helps to move swiftly between the activities, and notify application & user of various events. The activities we link to/from are capable to listen to the intents and respond to them.

The next chapter in developer.android.com is, I feel, not as good as the first because it does not give us the step by step guide of everything in detail. I felt the need to find some other tutorials which could be handy for a beginner like me where every small element is described with examples.

Layouts are the essential things to know when we start learning android. Android layouts are written in XML. It is a resource that defines what to see on the screen which organizes the child controls such as button or text controls or images. I found it easy to start building layouts in XML. There are a number of different layout types that can be used to organize controls on a screen and we can choose the appropriate layout in accordance with our requirement. Layouts can be nested if needed.

I can use the style resource to define the format and look for a UI and the style can be applied to an individual View or to an entire Activity or application. Android uses XML for styles. Android also uses XML for strings, colors and others. A string resource provides text strings for application with optional text styling and formatting.

What I came to know as a thing of vital importance is Android development platform helps to make the application work itself across all the devices with wide variety of resolution, screen sizes, and screen densities by performing scaling and resizing to give user the feeling that using android is one fluid experience. For this, all the images for different screen densities are saved in the drawable resources folder and the system will pick the correct one. The same thing can be done with the layouts, different layouts for small and large screens can be used, and system will use the right one, simply just to fit the screen.

Overall, I'm beginning to grasp Android quickly. I could grasp wee bit of everything I learned. So in my view, through self-learning, Android Development will be challenging and exciting task to do but not a problematic and impossible task. I think, this is the era for the android developers as more and more versatile and powerful smartphones are built on android platforms. We just have to clear our mind and have the “let’s just do it” attitude to self-learn to develop android applications. I do really enjoy working with Android, and will definitely continue to do so in the future.

Basic blogger template : just posts, absolutely minimum

Here's a basic form of blogger template that you can use to build other advanced template. I always wanted to bake my own custom themes and templates for blogger but there's no official documentation - actually there are but not that developer friendly ! Further, inspecting existing template source code it is very hard to derive what follows. I mean, there are definitely rules and syntaxes to follow in blogger template but looking at any downloaded template can be intimidating to beginners.

So, this is very minimal template i'm presenting here. Make template a xml doc, inspect header and meta tags. All CSS style rules inside - under CDATA (it's xml). And minimum requirement for a blogger template is there should be at least one b:section This basic template has one section which includes a blog posts widget. To learn more about how sections / widgets work together please refer to links at footer.

Notes for further work:

1) JS can be troublesome. If nothing worked encode it or put the whole content inside script into CDATA.
2) Images needs to be hosted.
3) All CSS needs to be in one page or host it somewhere separately.
4) All JS needs to be in one page or host it somewhere separately.
5) Imagine different kind of "page" types and different kind of layout / templates you'd like to render depending upon different URLs, and imagine all of this to be done in single page XML file. Holy Shit ! There sure gonna be loads of if and else blocks if this has to be achieved in one page.

Enjoy. And if this work helped you get started in developing/designing blogger templates, don't forget to link my gist or this post in your website somewhere :) i'd be glad.

Implementing dual language feature in PyroCMS/CI?

Implementing dual language (multilingual / multi language) feature in CodeIgniter based PyroCMS?

Our Language Requirements : English / Nepali

Semicolon Developers are in trouble. All clients we have now are requesting websites in Nepali and English language. CodeIgniter and most of all CodeIgniter based PyroCMS has been our choice of development tool since a long time. Check other posts on echo and you’ll know what I am talking about.

PyroCMS or CI as is are designed to support multilingual feature. But we have yet to figure out what is the best and effective way to implement this.

For now, given the urgency of feature request of our client and our commitment to project deadline we did a little hack for supporting two language in PyroCMS as follows:

General UI and widget blocks or different “titles” are easy to translate by using the default CI Language Class refer here and here for CI.

1) We stored default language in session or initially session could be blank.
2) We used two links to switch language in frontend.

{{ if {session:data name="language"} == 'np' }}
<li><a href="{{ url:site }}language/en">EN</a></li>
{{ else }}
<li><a href="{{ url:site }}language/np">NP</a></li>
{{ endif }}

the /language controller does the magic !

3) Now for the navigation links we created two navigation groups and switched depending upon the language value stored in session.

{{ if {session:data name="language"} == 'np' }}
{{ navigation:links group="header_np" }}
{{ else }}
{{ navigation:links group="header" }}
{{ endif }}

4) /language/en or /language/np can be routed to a function through routes. A function can be used to get specific segment of the url . When it is fetched the necessary session modification can be done on function as:

This modification is done on the session variable (here language)
Finally routing to the base url page as per required

//...controller code
public function language($lang){

if($lang=="en" || $lang=="np") {

$this->session->set_userdata(array('language' => $lang));

}

redirect(base_url());
}

This operation is intended for dual language and can be extended further with required conditional statements.

FYI, this is not a perfect way to build multilingual feature. Problem can arise while dealing with more than two languages. If you have better solution let us know.

My First take on PyroCMS

What is PyroCMS ?

PyroCMS is a open source framework for content management system created with standard PHP/MVC framework CodeIgniter. It is light and simple to use and is for both the developers and the end users. Generally it is used for websites which contains large amount of content/articles. The content should be well presented to the user for displaying as per requirement . This is where pyrocms comes which can manage the display of those content as per requirement.

How PyroCMS can be customized to develop websites on it ?

PyroCMS provide the dashboard for administration section to be used for developing big content based websites easily.
As it provides various tools/modules for implementing the website design and functionality which are very necessary for the a perfect websites.

Modules such as:

Navigation: It is used for the navigate through out website links.
Blog: This is used for the articles to be posted like blogs, also they can be well surfed by the end users.
Comment: Users and guests can write comments for content published and share their views.
Pages: Add pages to the site with content that are mostly static or vary in time.There are many other modules that can used

Why PyroCMS is better than Wordpress, Drupal and other existing CMSes ?

All of the CMSes have not any fixed and standard framework for using it. Therefore it will be difficult for different developers to interact with various created sites. With pyro we are developing a cms with customized outlook and standard framwork which can be very developer friendly.

What can we do with PyroCMS ?

Being small and flexible, PyroCMS can be very usefull to small and to large content based sites.

What are PyroCMS Themes ?

Themes are the outlook that are presented to users. It contains the design that can be navigated by the users. PyroCMS provides suitable method to develop the themes. PyroCMS contains main layout and the partials files that make up the single website theme.

How to build PyroCMS themes ?

In PyroCMS Theme are structured in different folders like css for stylesheets files, js for javascripts and views for overall structure of the website. In views folder the main design is kept inside layouts which is the central look . The designs are splitted within the folder called partials which contains the design units like header, footer, sidebar etc. Also necessary information about the theme and the screenshot is also included for informations.

Lastly, using Pyrocms was very fun to use. It is more similar to CodeIgniter therefore people comfortable with codeIgniter may find it very easy to use. Also it is very useful for customizing our desired look and functionality. Also we should use it very calmly. Despite of few documentations and support i am sure user/develop would find it very handy.

Hot to create PyroCMS v1.3.2 Theme/ Step by step PyroCMS Theming Guide

A quick guide for creating PyroCMS Theme from a normal HTML / CSS template

Get any HTML /CSS template & follow the steps below!!

We prefer:
http://www.freecsstemplates.org
http://www.oswd.org

1. Install PyroCMS.

2. Go to installation folder -> addons -> shared_addons -> themes

3. There are two pre built themes. Copy either “minimal” or “conjuction” folder & paste it .

4. Here, we’ll use folder “minimal” . You’ll now see a new folder named “Copy of minimal”.

5. Rename it with the new theme name as u like. I’ll name it “tutorial”

6. Open the folder .

7. Open file “theme.php” in notepad++ or any other IDEs.

8. In the file

Replace “ class Theme_Minimal extends Theme “ with “class Theme_Tutorial extends Theme “

PTR : Old theme folder’s name must be replaced with the new folder name u gave to it. The first letter of name should begin with the capital letter.

Replace the text in between the single quotation mark as relevant.

Save & close the file.

9. Delete all the files in CSS folder & put the css file of ur new template in that folder.

10. Goto folder “views” -> then folder “layout”. There is a file “default.html” which is supposed to be like “index.html” of HTML/CSS template.

11. Open “default.html” in editor.

12. Also open the index.html file of downloaded template in editor.

13. Copy all the content of “index.html” in to the “default.html” after removing the initial content of “default.html” .

14. Replace CSS linking code in head section

With

{pyro:theme:css file=”your_css_filename.css”}

15. If u hav javascript file in templates…create JS folder in “Tutorial” folder & paste inside it..

16. Linking Js file from head section

{pyro:theme:js file=”filename.js”}

In case u hav multiple files…use same code multiple times bt the order of js/css should occur as it is in template head section

17. Now..we break down the file “default.html” into multiple files.

18. All broken mini files are called partials and they should be kept in folder “partials”.

19. Let’s check the breaking process..

20. Create a new file named “metadata.html” & then cut the code inside <head> tag & paste it to “metadata.html”.save the file in folder “partials”.

21. Create a new file named “nav.html” & then cut the code inside <head> tag & paste it to “metadata.html”.save the file in folder “partials”.

22. You can cut contents in side the <div> tags as well.

Suppose: default.html has following code

<div class=”nav”>
<ul>
<li>home</li>
<li>contact</li>
</ul>
</div>

Cut the contents inside <div></div> tag and paste it to new file & name it “nav.html” & save it to “partials” folder

23. Similarly break other codes from default.html file & save to partials.

24. Now we learn to link the files in folder”partials” so that the code we broke is included in default.html.

In head section

<head>

{pyro:theme:partial name=”metadata”}

</head>

In <div> tag

{pyro:theme:partial name=”nav”}

<div/>

25.Now we learn to use images in the theme we working for.

26. copy the folder “images” from the downloaded template & paste it to the theme folder.

27.check CSS file & find the images it has been using..then cut all images from folder “images” except those being used by css file & paste it to new folder named “img”.

28.replace the code in other files.
initial code :- <img src=”button.png” alt=”submit”/>

New code :- {pyro:theme:image file=”button.png”}

29. to get the navigation menu set by from the admin panel in certain div

{pyro:navigation:links group=”header”}

</div>

30. to get the content set by admin (dynamic content) in any div
<body>

{pyro:template:body}

</div>

There go you. Your PyroCMS Theme is now ready to be used.

How to create PyroCMS v1.3.2 widgets ?

A quick guide for creating new widget in PyroCMS.

1. Go through these folders
CMS_installed_folder -> system -> cms -> widgets

2. All these folders are for separate widgets.copy anyone. We’ll use it as reference to create a new widget.

3. Paste that folder in
CMS_installed_folder -> addons -> shared_addons -> widgets

4. Here suppose I copied “navigation” widget folder & pasted.

5. There is folder name “views” & a file named “navigation.php”

6. Two more files inside “views” folder ..named “display.php” & “form.php”. “Display.php” is for frontend

7 “form.php” is for control panel.

7. Every widgets should hav the above mentioned folder & files bt with the name according to ur requirement.

8. Now we edit the files in the folder we pasted.

9. Suppose we are displaying categories via this widget.

10. Rename the folder to ”category”.

11. Rename file navigation.php to category.php.

12. Open category.php in text editor.

13. Rename Widget_navigation to Widget_Category. The replaced text should contain the name of ur file u r editing & name must begin wid the capital letter.

14. ‘en’ , ‘pt’ ,’ru’ etc are the languages..so u can delete them except “en” . en is the English language..

15. Replace text ‘en’ => ‘navigation’ with ur widget name. ‘en’ => ‘category’ in title array.

16. Replace text ‘en’ => ‘Display a navigation group with a widget’ with ‘en’ =>’description of ur widget’.

17. Change value of $author,$website & $version as u wish.

18. The $fields is the array of fields that will be appearing in the form for control panel & passing the value while calling a function.

Here, run function is for running the query. If input has been taken from form in the control panel ,then the parameters should be passed to the function with variable “$options” else it will be just run(). We fetch an array in $options from the from in control panel.

19. U hav to load the model file which contains the database query u require. Or u can create your own model with reference of old model. If u dnt want to create new model..u have to add a function that can return the require the data from database in it.

20. That function called from run function and returns the array data to run function.

21. Run function returns it to display.php & this file renders the content to front end.

22. Grab the array in display.php & use it to display the require contents.

To install the widget :

1. Goto admin panel.

Content -> widgets -> drag & drop widgets from list to the available areas.

3. Copy the code {pyro:widgets:instance id=”3”} & paste it the front end html file where u wud like the widget’s content to be displayed.
