App Rendering Differences on Chromebooks

Because Android apps run in a window under Chrome OS, there are small differences in how apps are rendered on Chromebooks. These differences are outlined below.

Tasks, Windows, and Transparency

A task consists of a stack of activities that the user interacts with when running an app. Tasks are presented on Chrome OS as a window with a title bar, with the apps layered on top of each other. Each activity can then be partially translucent, allowing the lower layers to show through.

In a conventional Android app, the previous task or the desktop shows through beneath the task. In this way there is always something visible beneath a translucent task.

This does not work in a window environment for the following reasons:

To mitigate this problem, Play for Chrome OS draws a semi-transparent rectangle behind each window. For this reason, apps can never be 100% transparent when running under Chrome OS, even when using the Theme.Translucent.NoTitleBar theme.
