Android does not use the JRE... it uses its own runtime optimized for mobile applications, the Dalvik VM. however, it has most of the features of the JRE.

Does android work with JRE 7?
I need to close a popup window in Salesforce1.

When it opens in a normal browser, the popup is closed using Window.close()

But in case of Salesforce1(App Browser), the Window.close() does not work. Is there any workaround to close the popup?
