Navigate to spideroak.com/opendownload. Select the Appropriate ‘Android (sideload)’ button to download the application onto your device. Once downloaded, you can ‘swipe’ down to select the downloaded file, which will ‘launch’ it, beginning the installation.
If you have not enabled it previously, you will be prompted to allow your device to install applications from unknown sources.
Follow the onscreen prompt and go to your ‘Settings’. Toggle the option ‘Allow from this Source’ in your settings, then select your device’s ‘back’ button to return to the previous page.
If prompted to Install, select the ‘Install’ option. Your device should begin the installation process. Once finished you can launch the CrossClave application from your device’s application menu.
