Bypass the Prompt and Clear Acrobat Cache

Since signing in is optional for basic viewing, you can dismiss the prompt and clear the app cache to prevent it from reappearing constantly.

Acrobat typically asks for Gmail sign-in to enable advanced cloud integration and direct attachment capabilities. If you only want to read the file, this step is unnecessary.

1
Dismiss the Sign-In Message

When the Gmail prompt appears on your screen, simply tap the 'X', cancel, or back button. If the PDF opens normally, no sign-in is actually required.

2
Open Android Settings

Go to your Android device's Settings app and navigate to 'Apps' or 'App Management' to view all installed applications.

3
Find Adobe Acrobat

Scroll down the list of apps and select 'Adobe Acrobat' to open its specific app info page.

4
Clear App Cache

Tap on 'Storage & cache', then select 'Clear cache' to remove temporary files that might be triggering repetitive and unnecessary prompts.

Security Warning: Never enter your Gmail credentials unless you are absolutely certain the sign-in screen is a verified authentication page generated by the official Google or Acrobat app.

Why does Acrobat Mobile specifically ask for Gmail permissions?

Acrobat Mobile offers integrations with Google Drive and Gmail to save edited files directly to the cloud or attach them seamlessly to new email drafts. The app requests access to enable these specific workflow features.

How can I stop the sign-in prompt from appearing every time?
