Android Application Drawer: dealing with configuration changes

We have gone a long way with the Application Drawer pattern on Android but there is always stuff to cover. On the previous posts we covered how to create a very simple and and then a more complicated one.

This time I want to show you how to deal with configuration changes and the application drawer.

A “configuration change” is an event that will destroy and recreate the Activity object. This means the views and variables of this object will be cleared. Following the samples we have been discussing, this means your Application bar state will be affected since we change how it behaves depending on the type of fragment we are in (a root fragment with the hamburger, or a sub section fragment that uses a back arrow instead).

Android Drawer and Fragment Navigation. A more “real life” scenario

Hey, I’m adding more meat into these series of fragment navigation tutorials. If you have been following my past entries you should have some knowledge on the Application Drawer design pattern and fragment navigation. If not, go and take a look at this post.

So far I have shown you how to create a very simple app: a home screen that allows to navigate to other sections via the drawer. Once you have reached one level of navigation the drawer is no longer accesible and you will have to navigate back to the home to reach it again.

Android Tutorial: Drawer and Fragment navigation made easy(ier….)

Hey, this time I want to write a bit about the Drawer design pattern in Android. If you have played with this I’m sure you have faced one or more issues regarding navigation (and the fragment’s back stack). I believe this tend to happen because we are used to let Android navigate those view stacks but when you transition to fragment transactions you are forced to pay attention to this.

You will find the code for this blog post here:

Note: this article has a “part 2” that improves on this code. You should still go through this post first.

Building a Pro Android App using Material Design–chapter 1

I’ve decided to write a series of tutorials aimed to create modern android apps using the concept of material design. As usual I’ll go baby steps but I will also assume you have knowledge on the platform and specially on Java programming. OOP is a must as well.

This few paragraphs will be dedicated on the focus of the app, or in other words what the app should do. It has to be generic enough so the sample is helpful to a broader audience but not to much to avoid unnecessary code complications.

For now we will do a simple product catalog that will be using the specs detailed on the material design guide by Google.

It’s important to state that we will not see a lot of material design during the few first chapters ! We will get there in time !
