INSTALL_PARSE_FAILED_NO_CERTIFICATES / App not installed as package appears to be invalid
The APK isn’t signed (or the signature is invalid for this Android version), so it can’t be installed.

Two steps away (33)
BucketAlreadyExists: The requested bucket name is not available
S3 bucket names are global across all AWS accounts, and someone else already uses this one.
AccessControlListNotSupported: The bucket does not allow ACLs
The upload sets an ACL (like public-read), but the bucket uses “Bucket owner enforced” Object Ownership, which disables ACLs.
S3 EntityTooLarge: Your proposed upload exceeds the maximum allowed size
A single PUT can be at most 5 GB (and presigned POST policies can set lower limits); larger files must use multipart upload.
Android: INSTALL_FAILED_UPDATE_INCOMPATIBLE
An app with the same package name but a different signing key is already installed on the device.
