To install an app from the wesite, you must opt-in for installing unknown apps.
Opt-in for installing unknown apps
Android blocks unknown installs until you opts into allowing the installation of apps from other sources. The opt-in process depends on the version of Android running on your device:
- On devices running Android 8.0 (API level 26) and higher, you must navigate to the Install unknown apps system settings screen to enable app installations from a particular location
- On devices running Android 7.1.1 (API level 25) and lower, you should enable the Unknown sources system setting, found in Settings > Security.
Note: When you attempt to install an unknown app on a device running Android 7.1.1 (API level 25) or lower, the system sometimes shows a dialog that asks you whether you want to allow only one particular unknown app to be installed. You should allow unknown app installation.
In both cases, you need to complete the opt-in process before you can download and install our apps onto your device.
Now that your device is set to properly receive an application , you need to download the application from the web.
Download the APK file through a web browser on the Android device you are using – you should see a notification in the menu bar that will allow you to select for installation.
After the file is loaded and installed, the application should work just as any program would if it was installed from the Google Play store.
