Advertising Identifier in the IOLib¶
IOLib Android requires the Advertising ID (AD_ID) to determine all INFOnline Measurement key figures (clients/visits). This ID is used to ensure measurement across all sites.
Android 13: Permission required¶
All apps with targetSDK version 33 (Android 13) and higher must actively declare the permission for the AD_ID in the manifest in order to be allowed to retrieve the advertising identifier from Google Play Services.
If this (install) permission is not given, a null AD_ID is passed.
If the AD_ID is not available to the IOLib, other identifiers can be used in a fallback, but these are significantly less precise and cannot be used for cross-site measurement.
Therefore, we strongly recommend to enable the Permission for the AD_ID as follows:
1 2 3 4 5 6 7 8
