Fix Acrobat Reader Not Enough Memory Error When Opening PDF on Android
Question details
The user is unable to open or download PDF files from Document Cloud on an Android tablet because the application prompts a memory shortage error, despite having sufficient free storage.
- Product
- Adobe Acrobat Reader
- Device & OS
- Android
- Scenario
- Downloading or opening a PDF file from Document Cloud using the mobile app.
- Observed behavior
- The application displays a 'not enough available memory' error message and fails to load the PDF document.
Verify the difference between your device's active memory (RAM) and internal storage (ROM) in your Android settings, and ensure your device has a stable internet connection for accessing cloud files.
Clear App Cache and Close Background Applications
Free up active device memory (RAM) and remove temporary app data that might be causing conflicts when loading PDFs.
Android devices can run out of active memory (RAM) if too many applications are left running in the background. Clearing the cache and forcing background apps to sleep often resolves memory allocation errors during PDF downloads.
Tap the Recent Apps button on your Android device (or swipe up and hold from the bottom of the screen) and swipe away unneeded applications to close them.
Navigate to your device's Settings app, tap on 'Apps' or 'Apps & Notifications', and find 'Adobe Acrobat' in the list.
Tap 'Storage & cache', then tap the 'Clear Cache' button to remove temporary files that might be corrupted.
Open the Acrobat Reader app again and attempt to download or open your PDF file from Document Cloud.
Test PDFs from an Alternative Storage Provider
Determine whether the memory error is specific to Adobe Document Cloud or if it affects all file sources on your device.
Update the Mobile Application and Operating System
Install the latest bug fixes and memory management optimizations for your device.

Frequently Asked Questions
Why does my Android tablet say not enough memory when I have plenty of storage space?
Android devices separate Storage (where files are permanently saved) from Memory (RAM, which runs active applications). You can have gigabytes of free storage space, but still receive a 'not enough memory' error if too many apps are running in the background consuming all available RAM.
Will clearing the app cache delete my downloaded PDF files?
No. Clearing the app cache only removes temporary files that the app generates while running. Your saved PDF files, documents, and account data will remain untouched.
How can I view a Document Cloud PDF if the app won't load it?
You can try logging into Adobe Document Cloud through a mobile web browser, downloading the PDF file directly to your device's internal storage, and then opening it with a lightweight PDF viewer like WPS Office.
