Builder Pattern

In Object-Oriented Programming (OOP) we spend most of our time creating objects or instances of classes. We usually prefer constructors when we create these objects. However, increasing the number of fields leads us to think differently because of the exponential and unnecessary complexity of the constructors. Builder pattern, on the other hand, overcomes this issue by using a builder to create an object in a step by step manner.

Best Practice to Instantiate Fragments with Arguments in Android

There are some ways to instantiate and pass data to fragments in android development. However, you must be careful when you do that and you should avoid the wrong approaches while you are instantiating and passing data to fragments.

The most recommended way of instantiate fragments with arguments is to have factory methods for this task.

Also, another important topic is about how to pass data to the fragments while instantiating them. In this case it is tempting to directly access the fields of your fragment and assign their values. However, this is the wrong approach. Because when your application send back to background and the other applications require more and more memory then your application and its resources will be cleared from the memory to open up space to the new ones.

Change Language Programmatically in Android


Published locale-helper as a library which can be found at

While developing your awesome application, sometimes you are required to add a feature to change the language of your app on the fly. However, Android OS does not directly support this behaviour. And therefore, you need to solve this situation in some other ways.

Here is the appropriate way of changing the locale of the application:

There are some difficulties which you have to overcome to change the language programmatically.

  1. Your application will not remember your language change after it is closed or recreated during the configuration change.
  2. You should update currently visible UI properly according to the selected language.
