  • Migration is difficult

Integrating data in Realm

  1. Configuration
  2. Initialization
  3. CRUD operations
  1. Configuration
    • Single Module support
      • add the following to your app build.gradle file
      • compile 'io.realm:realm-android:2.3.1’ in your dependency
    • Multiple module support
      • add the following to your Project build.gradle file
        classpath "io.realm:realm-gradle-plugin:2.3.1" in your dependency
      • add the following to your app build.gradle file
        apply plugin: 'realm-android'

    thats it RealM configured in your project.

  2. Initialization
    • Init the Realm in your Application class and its custom configuration
      public class MyApplication extends Application {
            public void onCreate() {
            RealmConfiguration realmConfiguration = new                             
    • If you want can add database encryption by using application keystore file.
  3. CRUD Operations.
    1. A class can act as a table - query is not needed.
      Class Dog extends RealmObject{
              String key = "abc";
              int key = 123;
                  private int sessionId;
      • All the fields inside the class act as a column.
      • The field with @PrimaryKey annotation act as primary key for the table.
      • The field with @Ignore annotation can not be considered as a column - this filed ignored and no column is created for the filed
    2. Creating Entry.
      1. prepare UNMANAGED entries - does not having default entry in the table.
        Dog dog = new Dog();
      2. prepare MANAGED entries - can have its default entry in the table
        Dog dog = realm.createObject(Dog.class);;
    3. inserting into db
      • Get a Realm instance for this thread
        Realm realm = Realm.getDefaultInstance();
      • Before doing any write operation we must call
      • Do your write operation after beginTransaction.
        // Persist unmanaged objects
        final Dog managedDog = realm.copyToRealm(dog);
        // Create managed objects directly
        Person person = realm.createObject(Person.class);
      • After your write operation commit your updates into corresponding table

Examples :

  • Write operation
    Dog dog = new Dog();
    final Dog insertedRow = realm.copyToRealm(dog); 
  • Update operation
    dog.setName(“another name”);
    final Dog insertedRow = realm.copyToRealmOrUpdate(dog); 
  • Read Operation
  • Read Operation with conditions
    realm.where(Book.class).equalTo("id", id).findFirst();
                    .contains("author", "an")
                    .contains("title", "re")
  • Delete Operation
    // remove a single object
        Dog dog;
  • Truncate operation

The future is already here and hope you do not miss out on it. There is a host of mobile technology developments happening and if your business is not keeping with the pulse, then you may miss out on a host of future-ready ideas that your competitor may action before you. So here’s another take on the what the future of mobile looks like for 2017 and beyond. There are plenty of articles already providing info on the statistics and numbers in mobile trends, but in this particular article we will focus on providing few real-life examples of how these technologies may be used in the near future. We hope that these ideas will tickle your brain cells too and help your churn out better ideas of your own! Happy thinking!

1. Hybrid Mobile Apps Development

This is a trend which has been around for sometime and is not entirely new. But this is something which many small business owners have to give serious thought to if they still haven’t gone in for a mobile app. Using a hybrid technology to develop apps can save them time and money and they can still deploy their app on multiple platforms. Also, the future trend is to have small businesses develop their own apps which will save them a ton of money. There are quite a few tools and utilities out there which support even non-technical users to get their mobile app solution up and running like AppMakr, jQueryMobile, PhoneGap, Appian, DropSource, etc.

2. Location- based Technologies

Apps like Uber are already making good use of location based GPS services. There is a plethora of opportunities still waiting to be tapped in this field. iBeacon technology is a value addition to make shopping experience better for a user in a brick and mortar environment. A beacon sensing app on the customer’s mobile would listen to the signals given out by beacons in a store which would enable sending customers highly contextual, hyper-local, meaningful messages and advertisements on their smartphones depending on their exact position in the store. Beacon technology uses BLE (Bluetooth Low Energy) which provides a digital extension to the physical world.

3. Cloud-based Apps

Cloud based apps have been around now, but what is new is the great upsurge in the use of multiple devices connected to mobiles. The focus is to integrate and sync mobile apps to these multiple devices. Therefore, the cloud approach in the near future will have to enable technologies like IoT, AI, and wearables for multiple functionalities. It also opens up myriad opportunities in healthcare, education, security, automobiles and home technologies.

4. Virtual Reality/Augmented Reality

With wearables like Google Glass creating a never-before opportunity in the field of Augmented Reality, last year’s most popular (100 million+ downloads) app Pokémon Go was proof of how a well-designed AR app can make kids become more active. Also, the healthcare field is throwing up a wide area of possibilities for AR apps like apps for Medical Inspection, Ingestible Sensors, Hearables, Smart Glasses and Moodables. Moodables are devices which can read your brainwaves and send low intensity currents to it to elevate your mood. There is no doubt that they have the great possibility of becoming a man’s best friend some day in the near future!

5. Artificial Intelligence & Automation

The newly launched Amazon Go store is a fine example to show AI is paving the way for future mobile technologies. Very soon we can also find self-serving kiosks which will completely remove the human component. In addition to this Amazon, has also piloted and made its first successful drone delivery, which is expected to become commonplace soon. As Amazon is making of use of Deep learning algorithms, Computer Vision and Sensor Fusion technologies to make the ‘Just Walk Out’ technology a reality. This is just the tip of the iceberg and the number of possibilities are numerous. But there are other issues like security that are sure to crop up. As long as the automated drones are executing critical first aid and saving the lives of people, we may not have too much to worry about as of now!

6. Internet of Smart Things

With the advent of devices like Google Home and Amazon Alexa (Echo) which are paving the way for Smart Home technologies, the day is not far off when all the devices of your home communicate with each other and obey your command. Already most of the new homes of the new homes in North America are being fitted with fixtures that are able to communicate with each other. The possibilities include manufacturers who develop these smart fixtures and others who develop the software needed to control these devices. 

7. Big Data & Analytics

The amount of data available on the various devices is growing day by day and the cloud makes it even more seamless. Making big data more human from 2017 is the top priority! The efforts should be focused on seeking more empathetic and qualitative bits of data and projecting it in a more visualized, accessible way to the end users. 

8. Wearable Tech

From your Nike shoe with in-built sensors to your Fitbit activity trackers to Google Glass, there is a whole gamut of wearables that have already made their foray into the Smart devices market. A lot of research is also already being done on them and the future definitely looks quite ‘gadgety’. Eventually all the eye candy will be left behind and what will stay are the only wearables which really enhance the quality of life be it in terms of inspiring people to become more active or helping people to improve their productivity. 

All these trends seem promising and we are eagerly looking forward to the new possibilities that are opening up. But on the other hand, synthetic food is also another area, which is fast gaining popularity with some American stores already stocking burgers made from ‘Soylent’. For now, would like to pass on this one!

Drupal is one of the most popular open source content management system written in PHP and MySQL. Its functionality and usability are far greater than any other system, as it combines ingenuity with simplicity. When you want to build a high performance website, choose Drupal as it is highly flexible and scalable. Complex functionality and dynamic web pages can be developed using many out-of-the box modules provided by Drupal and customized according to your requirements.

Drupal development provides so much, but people make some common mistakes. Avoid these 10 costly mistakes:

1. Wrong folder structure

Using a wrong folder structure and installation of themes and modules at the root levels is a major mistake. Follow the right directory structure to the themes and modules as it will be hard to upgrade and debug.

2. Excessive coding

Avoid excessive coding on the site to implement the required functionality and use the Drupal modules to achieve the goals. Drupal provides core and contributed modules to solve most of the problems. But Drupal developers need to assess the risks associated with the beta or alpha version of modules as they might identify the deficiencies.

3. Hack core files and themes

Hacking the core files and themes makes your site vulnerable to hacking and it becomes almost impossible to apply security updates on your site. So don’t hack core.

4. Wrong module configuration

You must learn about the modules and its interdependencies before you configure and install on your site. Sometimes wrong configurations can lead to bugs or risks of security issues on your site.

5. Inefficient performance

Inefficient performance leads to increase in load time and leaves your site visitors frustrated. Aggregate CSS and Javascript files, configure caching and remove unused modules which will maximize the site performance.

6. Not backing up site

Take backups before making major updates or upgrades to their site. This will restore all your data in case of a major issue during updates or in case of data loss. This will also save precious time.

7. Not W3C-Compliant

Not following the w3c coding standards and guidelines is one of the major mistakes. Following the W3C guidelines ensures error-free and accurate coding.

8. Not implementing security policies

Not providing the suitable roles and permissions on your site can affect your site security. Always ensure that you authorize roles and permissions to users and no one is exploiting your site.

9. No anti-spam control

Always safeguard your site with anti-spam control measures, otherwise your site will be flooded with spam content. So take necessary precautions and enable spam control in comments and content.

10. Not selecting the right hosting service

You have done all the hard work, but selected a wrong host for your site. Your site passes through three different phases - development, deployment, and maintenance. Always use version control system VCS and keep your site (code and modules) up to date and select the right host who can handle spikes in your site traffic.

If you want to create a new website for your business or migrate from your HTML website, it is worthwhile to point out that building a website has become easier and faster using a content management system (CMS). Gone are the days of hard coding with HTML and PHP to create a full featured website. Thanks to the capabilities of open source CMS software, people no more need to break their laptops and log on to their website or blog.

There is an array of content management systems which are developed and backed by a strong community. There are three most common and popular open source CMS platforms for building websites – Drupal, Wordpress and Joomla. They have striking similarities. They are written in PHP programming using MySQL database to manage content, and licensed under free GNU General Public License (GPL). There are a number of themes and modules contributed by the developer communities.

There is not one-size-fits-all approach to choosing the best CMS according to your business goals, budget and requirements. Below is a description of the three top open source CMS tools as a starting point for businesses to choose the right CMS in terms of functionality.


Drupal is one of the most successful CMS platforms with a large eco system of modules, themes, templates and supported by a strong community of loyal drupal developers who are always willing to contribute to Drupal. The CMS software is simple, flexible and scalable which leverages an array of tools to organize complex content for developing websites. However, Drupal development needs a high degree of programming knowledge for providing custom features and functionality compared of the all three CMSs. Drupal provides highly dynamic features to create advanced and versatile websites for eCommerce, governments, community, blogs, social networking, education, restaurants, and much more. Drupal is also SEO-friendly and sites built with Drupal ranks high on search engines than Joomla.                         


Wordpress is a blogging platform with innovative and user-friendly features using exquisite themes, templates supported by a comprehensive documentation. The blog software is easy to install and manage a site, which is its strongest point. You can tweak your blog with a wide repertoire of themes, plugins, and widgets. A wordpress developer needs no technical expertise, unlike Drupal. However, the CMS software is known for ease-of-use to build simple blogging and news sites even by non-technical users.


Joomla is sandwiched between Drupal and Wordpress when it comes to user-friendliness, capabilities and developer community support. Joomla offers a middle ground in terms of complexity and ease-of-use with regard to installation and deployment. You can run managing complex sites like blogs, newsletters, and everything using Joomla. It has beautiful themes, templates and extensions that cater to both designers and developers. You can create advanced websites using Joomla with relatively little effort in knowing about the structure.   However, when it comes to providing custom design and features it is complex, more so if you are not familiar with coding and web development.


Using Drupal or Wordress or Joomla - which one is the best? If you are looking to build a simple site for blog or news, Wordpress is the preferred choice and user-friendly for the non-technical wordpress developers. If you need a robust, scalable, secure and a highly customized website, Drupal offers the most complex solutions that you need. Drupal developers are passionate and strongly back the Drupal platform. Joomla also has a dedicated developer community support through forums and even books. It is ideal for an easier learning curve with ready-to-go templates. Still not sure? Please contact us and we can help you decide the right platform for you.

The upcoming Drupal 8 release provides more than 200 new features and improvements from over 2400 contributors. Drupal 8 development is expected to set new benchmarks for ease of use, responsiveness and faster page loads for high performance. In the meantime, Drupal 8 is currently in the beta stage of the release cycle. We’ll have a look about the routing system in Drupal 7 and then learn how the routing process of Symphony is adopted in Drupal 8.
In Drupal, a request is handled on the basis of the path it is recognized and returns to some sort of content. Else, Drupal gives a 404. Drupal maps the URL paths with the relevant page and access callbacks.
Drupal 7
In Drupal, hook allows you to register paths to access titles, arguments and other requirements.  Drupal 7 modules make use of associated page callbacks to paths in hook_menu().
Menu links
Contextual links
function example_menu() {
  $items['hello'] = array(
    'title' => 'Hello world',
    'page callback' => '_example_page',
    'access callback' => 'user_access',
    'access arguments' => 'access content',
    'type' => MENU_CALLBACK,
  return $items;
Drupal 8
Drupal 8 architecture will feature the routing process of Symfony, which offers much more flexibility and simplicity. Drupal 8 is taking the route of Symfony, which makes it easier for Drupal developers to get started. 
In Drupal 8 page callbacks are transformed into responses. The available routes are now configured in a file called{module}. routing.yml?in the module folder. A path will return multiple routes.
  path: '/hello'
    _content: '\Drupal\example\Controller\Hello::content'
    _permission: 'access content'
'Defaults' keys:
Defines the default properties of a route. Provide one of the following to specify how the output is generated.
    Drupal 8 provides a method to generate a response.
    If specified, the _controller is set based on the request's mime type, and fills the content of the response with the result of the specified method (usually a string or render array).
    If specified, the _controller is set to HtmlFormController::content, which responds with the specified form. This form must be a fully qualified class name (or service id) that implements FormInterface and usually extends FormBase. Indeed, form building has also become object oriented!
    If specified, the _controller is set to HtmlEntityFormController::content, which responds with the specified entity form (specified as {entity_type}.{add|edit|delete}).
    If specified, the _controller is set to HtmlFormController::content, and _content to EntityListController::listing, which renders a list of entities based on the entity type's list controller.
    If specified, the _controller is set to HtmlFormController::content, and _content to EntityViewController::view, which renders the entity based on the entity type's view controller.
    The title of the page (string).
    The title of the page (method callback).
'Requirements' keys:
Determines what conditions must be met in order to grant access to the route.
    The current user must have the specified permission.
    The current user must have the specified role.
    The allowed HTTP methods (GET, POST, etc).
    Set to https or http. The request scheme must be the same as the specified scheme. This property is also taken into account when generating URLs (Drupal::url(..)) rather than routing. If set, urls will have this scheme set fixed.
    A custom access check for adding new nodes of some node type.
    A generic access checker for entities.
    Mime types.

At DrupalCon Chicago, while delivering the keynote speech Dries Buytaert said: “If I were to start Drupal from scratch today, I'd build it for mobile experiences first, and desktop experience second.” He believed in it and took the big initiative to build a mobile-friendly CMS. Today most of the mobile features are implemented in Drupal 8. Here different mobile initiatives in Drupal 8 development are outlined:  

1.  Mobile responsive themes

Drupal 8 is built with responsive design with the ability to respond and adjust to multiple screen sizes and browsers. Now there are so many unconventional devices, which has to be kept in mind and designs need to be supportive. So, like Dries visioned it all Drupal 8 themes are built primarily for mobile experience and then desktop.

2. Administrative forms

Mobile-friendly admin toolbar in Drupal 8 stands out. The mobile administrative solution allows users to easily create tasks on mobile devices. The admin toolbar provides the ability to toggle from horizontal to vertical on the screen based on the orientation.

3. Breakpoints

Drupal 8 is built with Breakpoints which will be very useful for the front end developers. Breakpoints are different widths or break points in which the layout and functionality changes.

4. CSS standards

Improving CSS coding standards was the next big thing planned for Drupal 8. It follows SMACSS-style categorization of CSS rules making it more scalable and flexible.

5. Front end performance

The transition from Drupal to Mobile is challenging for front end developers. Front end performance is always business-critical for websites With mobile-first approach, Drupal 8 is built for high performance on all smartphones and tablets. Drupal 8 provides support for HTML5, Javascript and responsive design and optimized for mobile devices to enhance front end performance.

The pace of Drupal 8 development is brisk and the process is nearing completion. It will be a huge step into the mobile world, which has been keenly awaited.
