Custom Cordova plugin

Cordova plugin ?

Cordova provides a bridge between JavaScript and native code, enabling you to write native code that gets exposed to your app via a common JavaScript interface.

Each method exposed by a plugin’s JavaScript interface is mapped to a method in the plugin’s native code via the Cordova bridge, which also enables you to pass parameters back and forth between the JavaScript and native methods.


A Cordova plugin typically consists of:
  •     Native code for each supported platform
  •     A common JavaScript interface
  •     A manifest file called plugin.xml

The conventional structure for a Cordova plugin supporting both Android and iOS is:

- Plugin top-level folder
     - plugin.xml
     - src/
        - android/
           - <Java source code>
        - ios/
           - <Objective-C source code>
     - www/
        - <JavaScript interface>
     - Plugin.xml

 A plugin may also include additional native resources and these are identified in the plugin.xml manifest file. This manifest file is read by the plugman command-line tool, which is used by the Cordova command-line interface.

For more detailed information about the plugin.xml manifest file, refer to the Cordova Plugin Specification.
       
How do I create my own custom Cordova plugin?

To create your own custom Cordova plugin, you must write:
  • JavaScript that provides the interface for calling your plugin from within a Cordova-based app.
  • Native code that provides the functionality you need. You should write native code for all native supported platforms.
  • A plugin.xml manifest file that defines your plugin and how plugman should incorporate it into any Cordova-based app.

Understanding Top line and Bottom line?

Understanding Top line and Bottom line? Top line – It’s the revenues generated by a company or what you might call the gross sales. When people talk about the company’s “topline growth”, they refer to an increase in its gross sales or revenues. When companies speak about the need to increase their topline, they are discussing about the need to focus on generating/increasing sales. This is money that is coming in before any expenses are deducted. Bottom line – The bottom line is the income that is left after all expenses have been deducted. You might also call this the company’s net profit. Some of the expenses that are usually being deducted are things like loan repayments, loan interests, administrative costs, taxes and even salary to employees. So there could be a big difference between the Top line revenues and the Bottom line revenues. A company’s bottomline can also be referred to as net earnings. Bottomline usually shows the efficiency of the company in controlling ...

Scrum Master vs Product Owner

The most common confusion in the 2 roles of Agile-SCRUM is between Scrum Master & Product Owner. The Scrum Master is in charge of making sure the Scrum process is followed. The Product Owner (PO) is the person in charge of making sure the product succeeds in the direction the company wants to go. The PO does this by setting priorities of product backlog items, making sure all needed parties are there for both the sprint planning and sprint review (both are very important). If something occurs and either the scope explodes or decisions need to be made, the PO is the person who gives the answers to the decisions. Product owner act as the feature prioritize(r) and main point of contact between business/customer and IT team. If product not succeed and probably reason is prioritization issue then product owner may be "single wringable neck" person. The Scrum Master is making sure the process gets followed and working through the adaptation of Scrum to your organization. By do...
