Summarize the following:
Tap the Google Drive app icon, which resembles a green, yellow, and blue triangle on a white background. This will open Google Drive for your Android's main Google Account.  You can switch to a different account by tapping ☰ and then tapping the profile image for the account you want to use. If your Android isn't signed into the Google Account you used on your computer, you can sign in by tapping ☰, tapping your email address, tapping Add account, tapping Google, and entering your account's login information. Scroll through the Google Drive contents until you find the vCard file you uploaded from your computer. Doing so will prompt a drop-down menu to appear after around a second. It's in the drop-down menu. Google Drive will begin downloading the vCard file into your Android's "Download" folder. Press the Home button to do so. Once the vCard file finishes downloading, you're free to import its contents into your Android's Contacts.
Open Google Drive on your Android. Find the vCard file. Long-press the vCard file. Tap Download. Close Google Drive.
