google 自己把 flash 下架
http://gadgetguideonline.com/android/lollipop/how-to-enable-flash-player-on-android-lollipop/When you get a device with Android Lollipop (Android 5.0), or update your device to Android Lollipop, it is normal that you cannot browse websites that require Flash.
But this does not mean you cannot enable Flash Player on Android Lollipop.
Actually, it is very simple to enable Flash player on Android Lollipop devices. It is simpler than that on Android KitKat 4.4 (see this guide on how to enable Flash Player on KitKat 4.4) and Android Jelly Bean 4.1-4.3 devices (see this guide on how to enable Flash Player on Jelly Bean).
Of course, you need a third-party web browser, not the pre-installed Chrome for Android.
Firefox for Android and Dolphin browser and many others now work nicely with Flash in Android Lollipop.
