The following is the first few sections of a chapter from The Busy Coder's Guide to Android Development, plus headings for the remaining major sections, to give you an idea about the content of the chapter.
As we build
EmPubLite, we will need to make a number of changes to our
project’s manifest. In this tutorial, we will take care of a couple of these
changes, to show you how to manipulate the
AndroidManifest.xml file. Future
tutorials will make yet more changes.
Android Studio users will also get their first chance to work with the
This is a continuation of the work we did in the previous tutorial.
In these tutorials, you will see references to relative paths, like
res/layout/, and so on.
Android Studio users should interpret these paths as being relative to the
directory within the project, except as otherwise noted. So, for example, Step #1 below
will ask you to open
AndroidManifest.xml — that file can be found in
app/src/main/AndroidManifest.xml from the project root.
Our application will restrict its supported screen sizes. Tablets make for ideal ebook readers. Phones can also be used, but the smaller the phone, the more difficult it will be to come up with a UI that will let the user do everything that is needed, yet still have room for more than a sentence or two of the book at a time.
We will get into screen size strategies and their details
later in this book.
For the moment, though, we will add a
<supports-screens> element to keep our
application off “small” screen devices (under 3” diagonal size).
Android Studio users can double-click on
AndroidManifest.xml in the project
As a child of the root
<manifest> element, add a
<supports-screens> element as follows:
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="false" android:xlargeScreens="true"/>
