Early last month, Alex Mullis wrote an excellent article discussing everything you need to know about developing for Android Wear . We are going to take this a step further by developing a simple Android Wear App. Developing for Android is an exciting endeavor, but including Android Wear features in your app is even more fun, trust me!

Before we begin, please keep the following at the back of your mind. Wearable apps, even though they are very similar to apps built for handhelds, should be quite small in size and functionality. You do not want to attempt to replicate the entire functionality of your handset app on a wearable. Rather, you should look for ways to complement the handheld app using the wearable. Ideally, most operations should be performed on the phone, and the results sent to the wearable.

Material design introduces elevation for UI elements. Elevation helps users understand the relative importance of each element and focus their attention to the task at hand.

The elevation of a view, represented by the Z property, determines the visual appearance of its shadow: views with higher Z values cast larger, softer shadows. Views with higher Z values occlude views with lower Z values; however, the Z value of a view does not affect the view's size.

Shadows are drawn by the parent of the elevated view, and thus subject to standard view clipping, clipped by the parent by default.

The attribute android:shape is set to rectangle (shape files also support oval , line and ring ). Rectangle is the default value so this attribute could be left out if it is a rectangle being defined. See the Android documentation on shapes at [1] for detailed information on a shape file.

Shapes also support gradients but that is not being used here, again see the Android resources to see how a gradient is defined. The shape is applied to the laypout using android:background="@drawable/customborder" . Within the layout other views can be added as normal, in this example a single TextView has been added, the text is white (FFFFFF hexadecimal RGB). The background is set to blue, plus some transparency to reduce the brightness (A00000FF hexadecimal alpha RGB value). Finally the layout is offset from the screen edge by placing it into another layout with a black background and a small amount of padding. The full layout file is thus:

Sometimes being a software engineer can be very frustrating. It has been one of those days, despite the fact that things started out in the right direction.

I got a request from a creative director on my current project to add a dashed line to a layout. According the official Google documentation , this is out of the box functionality. After a brief scan of the SDK guide, I was ready to rock and roll.

However, after applying the same technique to my production code, I discovered something troublesome: The line showed up completely solid on an actual device ( Figure B ).
