Android installation troubleshooting

AppBarn downloads APK files; Android decides whether installation is allowed. An AAB is not directly installable.

Find the problem

What you see	What to check	What to do
Share unavailable	Link invalid, revoked, expired or Build no longer ready	Ask for a new Share Link
Download fails	Browser/network, access link or expired short-lived URL	Reopen the Build page and request a new download
Device blocks installation	Browser/file-manager install permission, managed-device policy or Play Protect warning	Review the warning and confirm the build is trusted; follow device policy
App not installed	APK signature, installed app with a different signer, OS/device requirements or damaged download	Ask the developer to check signing and compatibility; download again
Only Download for AAB	An Android App Bundle needs processing	Use a suitable development or distribution tool to create installable APKs

AppBarn does not override Android security controls or replace developer signing. Do not bypass organisation restrictions.
