Before we begin, just some things you need to consider. Since Adobe is no longer supporting the software, it could prove to be a bit unstable on Android 4.1. Also, because the Chrome for Android doesn't support Flash, those rocking Android 4.1 need to have a stock browser installed. Additionally, without support from Adobe, installing Flash could lead to security issues. Finally, make sure that your device is set to allow third party software to be downloaded on your device. For those Android devices running 2.2, 2.3 or 3.x, go to Settings > Applications. On Android 4.x, you will need to go to Settings > Security.

On the page, ta on install to confirm your selection. When Flash is installed, head to your stock browser. For those running Android 3.0 or later go to Menu>Settings>Advanced>Enable Plug-ins. For constant Flash usage, click on "Always on" or if you want to decide when to run the software, click on "On demand".
Those with Android 2.2 or Android 2.3 should head to Menu > Settings (or Menu > More > Settings), which is where the "Enable Plug-ins" option can be found.
And that is all there is to it! You should uncheck the "Unknown Sources" third party software box for security reasons. Let us know if you were able to manually install Flash Player for your Android device using these directions by dropping a comment in the box below.
