Question details
Users are unable to open PDF files stored in Adobe Document Cloud via the mobile app due to a path validation error.
- Product
- Adobe Acrobat Reader
- Device & OS
- Kindle Fire / Fire OS
- Scenario
- Attempting to access and open PDF files synced from Adobe Document Cloud using a Kindle Fire tablet.
- Observed behavior
- The app displays a "Document Path not Valid" error message when opening cloud PDFs, even though locally saved files and desktop cloud access work correctly.
Ensure your Kindle Fire has a stable internet connection, as accessing documents from the cloud requires continuous network synchronization.
Update the App, Check Permissions, and Re-login
Refreshing your account session and verifying app permissions is the primary way to fix syncing and file path issues in Document Cloud.
This error often occurs when the app's authentication token expires or when Fire OS restricts the app from creating a temporary download path for the cloud document. Refreshing these elements usually restores access.
Open Acrobat Reader on your Kindle Fire, tap the profile icon or menu, and select 'Sign Out' to disconnect your Adobe account.
Open the Amazon Appstore, search for Acrobat Reader, and tap 'Update' to ensure you are running the latest version compatible with your Fire OS.
Go to your device Settings > Apps & Games > Manage All Applications. Select Acrobat Reader, tap 'Permissions', and ensure that 'Storage' is toggled on.
Relaunch Acrobat Reader, sign in with your Adobe ID, navigate to 'Document Cloud', and try opening the PDF again.
Reinstall the App and Contact Support
If standard troubleshooting fails, a clean installation can resolve deep cache corruption, though persistent issues may require escalating to Adobe Support.

Frequently Asked Questions
Why does Acrobat Reader display a 'Document Path not Valid' error only on Kindle Fire?
This error is typically caused by a compatibility issue between the Fire OS file management system and Adobe Document Cloud's sync mechanism, which prevents the app from locating or creating the correct temporary local folder to download the file.
Can I access my Document Cloud PDFs on my Kindle using a web browser instead?
Yes. As a reliable workaround, you can open the Silk Browser on your Kindle Fire, navigate to the Adobe Document Cloud website, sign in, and view or download your PDFs directly from the web interface.
Will clearing the app cache fix the document path error?
Clearing the cache can sometimes force the app to recreate corrupted file paths. You can do this by going to Settings > Apps & Games > Manage All Applications > Acrobat Reader, and then tapping 'Clear Cache'.
