android: exported needs to be explicitly specified for element <service#io.intercom.android.sdk.f-CodePudding

I'm getting a Flutter build error in AndroidManifest.xml

android:exported needs to be explicitly specified for element <service#io.intercom.android.sdk.fcm.IntercomFcmMessengerService>. Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined

There is no element called intercom in the AndroidManifest.xml file. I also added android:exported="true" in activity ".MainActivity" but the error still persists.

My AndoidManifest.xml file is as follows

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="social.myproject.app">

CodePudding user response：

This happens sometimes even if we add android exported. A workaround will be to set the targetSdkVersion to 31 and compileSDKVersion to 31 in android->app->build.gradle file

CodePudding user response：

Possibilities:

Have you tried to do "Invalidate/Cache and Restart"?
Have you tried to open the Project with the Android folder? It would display the errors if you missed anything in AndroidManifest.xml.
You can also try with flutter clean & flutter pub get to run again.

EDITED:

You have added some libraries and they haven't updated this service IntercomFcmMessengerService with exported = true/false

That's the reason why you are getting problems. You can do one thing that defines that service in your <application> tag with exported=true. It will override that service.

Might be that will work for you.

Hope it will help you.
