To install Adobe Flash Player ensure your device features Android 2.2 to Android 4.1. If you don’t know which version of Android your device features, go to Settings > About Tablet or Settings > About Phone. Note that if your device is running on Android Jelly Bean, you will need to navigate to Settings > Security and select the checkbox of Unknown Sources to avail app downloads outside of Google Play Store. Android would prompt you to confirm selection, so tap on OK upon prompt.
Now that you have enabled Unknown Sources, open the web browser on your device to download Adobe Flash Player from their official site. Again, as Google Play Store does not have the app as of now, the Adobe Flash Player may not be supported by devices that are powered by Android Nougat, and so Google Chrome won’t open the site. That is why you need to know how to download and install Adobe Flash Player from the third-party source in your compatible Android device.
Everything you download outside of Google Play Store is a third-party source or Unknown Source, as Google puts it forth. Search Adobe Flash Player Archives for Android on Google Chrome and open the first link on the organic search results of Google. Then, you will be directed to the help page of the Adobe site containing the respective archives for Android.
Adobe is yet to give a link to download Flash Player for newer versions of Android, so choose the link as per your older Android version. The Flash Player app would begin downloading automatically and complete the download within seconds. Once the download finishes, pull down from the top of your Android tablet, tap on the .apk file, and tap on Install upon prompt. Then, tap on Next and on Done once the app gets installed and navigate back into your tablet’s default browser to enable the Flash Player Plug-Ins.
In Android 3.0 or later, open Chrome, tap on the three horizontal lines, and navigate to Settings > Advanced > Enable Plug-Ins. In Android 2.2 or 2.3, open the three-line menu and go to Settings > Enable Plug-Ins. Once the respective plug-ins are installed on the device, you can start accessing flash-heavy content on Google Chrome.
Note that you would need a third-party app supporting flash, other than Google Chrome, installed on the tablet featuring Android Nougat to access the flash content.
