Multi Tab App with Async Task

CodeProject Objective: To create an android app, with multiple tabs catering different types of questions, in which data will be saved to SQL-Lite using Asynchronous approach (Async Tasks concept.)

This post will be covering only a part of the actual objective.
I created a Multi Tab application and each tab pointing to  a different fragment.
Now in every tab click the data has to be saved without blocking the user actions.
For this i have chosen Async Task concept.
As of now i just put up a simple dialog display demonstrating the Async actions while user navigates between the tabs.
In up coming post, i will finish the code for even saving the data to SQL-Lite database, thus completing the actual intent.

Shared Preferences and Yes/No Alert Dialog in Android

CodeProject In this post, my intent is to use the internal memory of an android and save / retrieve the data from different views.

We have several options to save data on a Android device, like Compact SQL, Files and Shared Preferences.

So, i have a One Page Application, which will accepts name and save it to the internal memory and then retrieves the data to display i on second screen.

My First Android App

CodeProject

I have always worked on .Net technologies like Windows applications using C#, Web applications using Asp.Net then moved to creating light weight Web applications using MVC Razor.  Apart from that stream, i have been working on Sharepoint 2007, Sharepoint 2010 and now Sharepoint 2013.

One of my client raised a concern of his application access via Mobiles and Tablets. I have looked at several options like . .

Why Server 2012 ?

CodeProject If you go through the Hardware / Software requirements of Sharepoint 2013, you can see that server 2008 R2 can also run sharepoint 2013.
We know Server 2012 is awesome and very useful in Usage and Performance perspectives , especially for Sharepoint 2013. But we cannot give such a vague answer when a client asks the same question.
                       Why Server 2012?

PowerShell - Wait for Retract / Uninstall before Remove

CodeProject This is a very small tip for SharePoint developers. Basically people hate PowerShell before knowing it. But you will love it once you start using it. Sooooo Comfortable.

So, as a part of PowerShell commands, we have UnInstall-SPSolution command for retracting a SharePoint solution and Remove-SPSolution command to remove the solution from any scope.

When you execute these commands in a sequence in a script (.ps1) file, Usually we end up with an error saying
 Remove-SPSolution : The solution "XXXX.wsp" has been deployed in the farm. Please retract the deployment before removing the solution.You can also use the
-override parameter to forcibly remove the solution, but you will not be able to retract the solution deployment.

JSLink - Custom JS Rendering in Sharepoint 2013

CodeProject JSLink is the new feature introduced in SharePoint 2013, loading off the burden of XSLT webparts from developer's mind.
Lets me show you an example. I have two lists "Movies" and "Books".

But I want to display them on a page like  . . .

All this can be done just by using Java script and without creating a single webpart.
Lets see how to accomplish this task.

Sharepoint 2013 - Avoiding Azure on Dev Box

Let us have a look at this error.
" The parameter 'token' cannot be a null or empty string "
or
" Microsoft.SharePoint.SPException: The Azure Access Control service is unavailable "

We might have encountered these issues in initial days of working with Apps.
To be specific, this happens with Auto Hosted or Provider Hosted SharePoint Apps.

My First Sharepoint-Hosted App in 2013

CodeProject I would recommend to read Apps in SharePoint 2013 post before going through this one.
I want to create a SharePoint-Hosted App in 2013 using Visual Studio.

I have created a SharePoint 2013 machine with all required software.
Just as a best practice, even if you are creating a standalone server, enable Active Directory Domain Services.
SharePoint 2013 works better when the system is in a Domain, rather than in a workgroup.

So, I have installed Windows server 2012, enabled all required features. Installed Office 2013, SharePoint 2013, Visual Studio 2012 and Developer tools for SharePoint 2013.

Apps in Sharepoint 2013

CodeProject
Why Apps? What's wrong with Solutions?
The world is getting smaller day by day, thanks to technology. Big desktops became Bulky laptops. Bulky laptops became Notebooks. Notebooks became Ultra books. Now the trend is moving towards Tablets and Smart phones.
So does our applications. Web applications becoming Apps.

SharePoint 2013 Issues Encountered

These are the list of issues I encounter while working on SP 2013 on VS 2012.

While setting up SharePoint 2013 in standalone mode, there are 2 kinds of errors which we may encounter at step8.
Just like many people I ignored it and verified Central Admin and created an application. So thought everything is working. But when you create applications like apps, then you will start getting weird errors like "xxxxxx component is missing, try installing it again"

So clear these issues first and then proceed.
