'tis a moot point, if you're looking to install or download Flash Player, because you can't, with Android. There is no more Flash Player for Android and there won't be another. Android is no longer comaptible with Flash Player. Playing Flash content is very processor consumptive and it drains your battery, also shortening the life of it. These browsers use "server side" rendering to reduce the load on your device.
Android (Google) recommends using either "Dolphin" or "Puffin" as your browser if you need to view Flash content with a mobile device running Android. They're both free in the GooglePlay store.
