Even if Flash Player on Android is no more supported by Adobe, it is still very easy to obtain it (eg, via Aptoide). The problem is that Chrome is not compatible with it. On my Galaxy Note 10 I can use it with the stock browser (it works like a charm). Unfortunately my friend has a Nexus 7 Tablet. We were successfull at installing flash but we can't find any browser that supports it (we tried Dolphin).
