Files on Google Drive on Android keep uploading. I noticed this problem when I was exporting old WhatsApp groups.
I will skip the long long paragraphs on how smartphones, WhatsApp and Google applications play an intricate part in our lives.
In the app, Recent Activity, there is a very long list of files “Waiting for upload” to Google Drive. Each file has a spinning hourglass, name and X to cancel. Pressing on the individual file X to cancel has no effect. Viewing Google Drive from the browser shows the files are already uploaded.
The usual tricks of force stop the app, restarting the phone, turning off wireless etc did not help. Google searches turn up suggestions to clear data. I can’t clear data as the original WhatsApp groups have long been deleted. This will cause me to lose my uploads.
So I sat down and went through the upload queue and using a computer, manually checked the contents of each file. It appears all of them are uploaded.
I cleared the Google Drive app cache only. The hourglass icon changed to a snapshot of the files. The queue disappeared.
