Android 12 Advertising ID

These days, data is very strict. From iOS 14.5, IDFA rule becomes strict and to collect this info, need to get user approval using permission dialog.

Google will follow Apple soon. This is kind of common sense.

Google announced Android 12 on Oct in 2021, but so far no change about Adverting ID.

From Google, the change previously announced from early 2022.

This is the current result without permission

When building application with Android 12 (API 31), apply this
Need to set permission (permission level is normal, so no dialog only install/update check from Google Play)
If missing permission, can get “00000000-0000-0000-0000-000000000000” same as iOS

Currently, this change does not have effect on, but Google said that it has an effect from early 2022.

If you are application developer, we need to implement following 2 ways to support ADID

<uses-permission android:name="com.google.android.gms.permission.AD_ID"/>

The latest version already had this setting. If import this,

17.1.0

From google

If you don’t want to collect ADID, but dependency has this.

In this case, we can override setting to remove ADID collection

<uses-permission android:name="com.google.android.gms.permission.AD_ID" tools:node="remove"/>

tools:node=”remove” override (remove) dependency setting.

Me, too. I want customers to use setting. We need ADID for ads.

In SDK developers, we can take 2 ways.

In 1 case, do we need to compile with API 31, no we can use this permission with under 31 level API.
