I set android:exported but I am still getting error: android:exported needs to be explicitly specified for <receiver>

Question

I am moving from SDK version 30 to 31 and I add android:exported in intent-filter but still I am getting this error:

Apps targeting Android 12 and higher are required to specify an explicit value for android:exported<\/code> when the corresponding component has an intent filter defined. See https:\/\/developer.android.com\/guide\/topics\/manifest\/activity-element#exported<\/a> for details.

Answer 1

The reason is because some of the dependency libraries that you're using have elements which do not have "android:exported" attribute.

• <\/li>
• <\/li>
• <\/li>
• <\/li><\/ul>

I resolve my issue. I just check the merged manifest and look for reciver. In onesignal, I found out reciver with intent filter defined without android:exported. I just add android:exported="false".
