Join David Gassner for an in-depth discussion in this video Creating a launcher icon, part of Building a Note-Taking App for Android (2013).
When you first create an Android application, it's populated by default…with a launcher icon, a picture of the Android robot.…Or you can create your own custom icon during the project creation process.…But when you're building a commercial app, you'll probably have a graphic designer…create your own custom icon. And you're going to need to create a…number of different versions of it. One for each of the common pixel densities…or screen densities that you'll find on different Android devices.…
The launcher icon is shown both in the action bar when you're working on a newer…version of Android. And, after you've installed the…application, it'll show up in the application list and sometimes on the…start screen. You can add the application to the start…screen by going to the application list, clicking and holding on the application,…and then dropping it on your start screen. When you first create the object the…application is populated with three different sizes for the application…launcher. There's one in a folder called Drawable…
Like its companions, this course will take you through building a complete mobile app from scratch; but this installment uses the Android SDK and Java to get the job done. Author David Gassner shows you how to install the SDK and the Android Developer Toolkit, create a project, save data on a device, build and control screen layouts, and create action bars and icons that control navigation.
These three related courses will use the same assets to develop the same app. (See Building a Note-Taking App for iOS and Building a Note-Taking App for Windows Phone 8 and Windows Store for more information.) Compare and contrast the different steps and discover the similarities and differences!
