XAPK File validation failed

Hi. Friend. I getting this error.
XAPK File validation failed
Because of obb file is in storage and the storage is permission is off by default. Manually i fix it by going in app manager and turn on the storage permission.   But this is not the right way. anyone know to fix it.

Anyone here who know how to fix this. ?

In some device the xapk file validation failed. Due to not permission to the storage. Anyone who know how to fix this .

Yes, that is a storage permission error. XAPK is a combined file format consisting of the .apk installation package and the OBB data file. Your OBB is probably being placed incorrectly. When the game loads up it is looking for the OBB but does not have the permissions to find it. Your app doesn’t ask for permissions and hence you get the Validation Failed Error message. Make sure you have checked the use ExternalFilesDir in your project settings and that should hopefully solve the validation error or give you a message asking for storage permission.

If that doesn’t work check if your OBB file is in your Android/obb folder.
