Constant is available both in configuration and run phases. angular.module('app',[]) .constant('endpoint', 'http://some.rest.endpoint') // define .config(function(endpoint) { // do something with endpoint // available in both config- and run phases }) .controller('MainCtrl', ...

Factory is available in run phase. The Factory recipe constructs a new service using a function with zero or more arguments (these are dependencies on other services). The return value of this function is the service instance created by this recipe. Factory can create a service of any type, w...

In class-based programming, the factory method pattern is a creational pattern that uses factory methods to deal with the problem of creating objects without having to specify the exact class of the object that will be created. Wikipedia reference protocol SenderProtocol { func send(packa...
The pipe (%>%) operator could be used in combination with dplyr functions. In this example we use the mtcars dataset (see help("mtcars") for more information) to show how to sumarize a data frame, and to add variables to the data with the result of the application of a function. librar...

In certain cases we need to cancel an image download request in Picasso before the download has completed. This could happen for various reasons, for example if the parent view transitioned to some other view before the image download could be completed. In this case, you can cancel the image down...
Copy and Paste following class in your package: public class MLRoundedImageView extends ImageView { public MLRoundedImageView(Context context) { super(context); } public MLRoundedImageView(Context context, AttributeSet attrs) { super(context, attrs); } ...

A BroadcastReceiver is basically a mechanism to relay Intents through the OS to perform specific actions. A classic definition being "A Broadcast receiver is an Android component which allows you to register for system or application events." LocalBroadcastManager is a way to send ...
Android allows programmers to place images at all four corners of a TextView.
