How to Stop Acrobat Mobile from Asking for Gmail Sign-In to Open PDFs
Question details
The user wants to know why Acrobat Mobile repeatedly prompts for a Gmail sign-in to view PDF attachments and whether this authentication is strictly necessary.

- Product
- Adobe Acrobat Mobile
- Device & OS
- Android
- Scenario
- Opening PDF attachments directly from an email client on a mobile device.
- Observed behavior
- Acrobat Mobile displays a sign-in prompt for Gmail, even though the PDF file can often be accessed without actually connecting a Google account.
Ensure your Android OS, Gmail app, and Acrobat Mobile app are all updated to their latest versions to prevent integration bugs from causing unnecessary pop-up prompts.
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.
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.
Go to your Android device's Settings app and navigate to 'Apps' or 'App Management' to view all installed applications.
Scroll down the list of apps and select 'Adobe Acrobat' to open its specific app info page.
Tap on 'Storage & cache', then select 'Clear cache' to remove temporary files that might be triggering repetitive and unnecessary prompts.

Adjust Default PDF App Settings
Adjusting how your device handles PDF links and defaults can prevent Acrobat from attempting unnecessary Gmail integrations.
Open PDF Attachments Instantly with WPS Office
Avoid frustrating sign-in prompts and integration issues by using WPS Office to open your email attachments. WPS Office provides a lightweight, fast, and secure way to read and annotate PDF files on your Android device without requiring unnecessary account connections.
- 1. Download WPS Office: Install the free WPS Office app directly from the Google Play Store.
- 2. Open Your Email App: Go to Gmail or your preferred email client and locate the message containing the PDF attachment.
- 3. Select the Attachment: Tap the PDF file icon to download it to your device and initiate the opening process.
- 4. Choose WPS Office: When Android prompts you to choose an application, select 'WPS Office' and tap 'Always' to set it as your default hassle-free PDF viewer.
