62.11 Configuring Freeform Activity Size and Position

By default, an activity launched into a different task stack while in freeform mode will be positioned in the center of the screen at a size dictated by the system. The location and dimensions of this window can be controlled by passing launch bounds settings to the intent via the ActivityOptions class. The first step in this process is to create a Rect object configured with the left (X), top (Y), right (X) and bottom (Y) coordinates of the rectangle representing the activity window. The following code, for example, creates a Rect object in which the top-left corner is positioned at coordinate (0, 0) and the bottom-right at (100, 100):

Rect rect = new Rect(100, 800, 900, 700);

The next step is to create a basic instance of the ActivityOptions class and initialize it with the Rect settings via the setLaunchBounds() method:

ActivityOptions options = ActivityOptions.makeBasic();

ActivityOptions bounds = options.setLaunchBounds...
