Adobe stopped support Flash player for Android during Android 4.1 (Ice Cream Sandwich) and remove Adobe Flash Player app from Google Play Store. However the flash Player plugin worked perfectly on Jelly Bean version right until 4.3 version, Android 4.4 KitKat flash is not supported.
There is a problem with the release of Android 4.4 KitKat, it disable flash and can’t view flash content on your browser, all it shows is a blank page.
Finally a member of the XDA Developers community has managed to find a workaround to get Android 4.4 KitKat Flash Player to work under this version, you can only enable Flash Player to work on Dolphin Browser, not able supported for other android browser such as Firefox, Chrome etc. By the way the tutorial can find in official dolphin FAQ web page.
Work On Android 4.4 KitKat Flash
Go to Google Play Store and download Dolphin Browser on your android devices.
Tap on Dolphin logo located on bottom left and select settings menu. Now tap “Settings” from the menu that pops up.
Find “Web content” by scroll down the menu, then set the Flash Player plugin to “Always On”.
Now install Dolphin Jetpack from Google Play Store.
Go to download
hacked flash player app and installed. Make sure that you have uninstall the flash player installed in your device and then install the hacked one for compatibility reason.
If your devices refused to install app outside Google Play, you may set in your device (Settings > Securities > Unknown resources) to allow installation of apps from unknown sources.
Please take note it might not work perfectly smooth due to not an official release, so pages with flash content will probably load a little slowly.
