Example 20 with Workspace

use of com.android.launcher3.Workspace in project android_packages_apps_Launcher3 by crdroidandroid.

the class Workspace method mapOverCellLayout.

    // TODO(b/128460496) Potential race condition where layout is not yet loaded
    if (layout == null) {
        return null;
