+      | mobile:getContexts | Retrieve available contexts, along with details associated with each webview (see [get contexts](/docs/en/commands/context/get-contexts.md)) in JSON structure. The details of each webview includes such as android package name and its window handles details (see [get handles](/docs/en/commands/web/window/get-handles.md)). The details of each window handle (which donated as `pages` in the JSON) contains such as url, title and id. The id is part of a window handle name. Therefore, by concatenating a string like "CDwindow-" + id, you can use the string for switching to window (see [set window](/docs/en/commands/web/window/set-window.md).) | | |
