Hello All, I am trying migrating my app to android...

Hello All,
I am trying migrating my app to android 12 by changing the target SDK version to 31 in build.gradle. As required, I have added android:exported flag to every activity/receiver/services/provider tags present in my manifest file. But still I am getting this error.

Manifest merger failed : android:exported needs to be explicitly specified for <receiver>. 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.

So I am guessing this issue is due to any 3rd party library whose manifest contains a receiver without android:exported flag.
I have also checked merged manifest file for missing android:exported in components of any third party libraries. But in merged manifest file also all activity/receiver/services tags has exported flag.
So how can I find that missing receiver which is causing the issue.

You can view the merged manifest, go to the manifest, there should be another tab at the bottom

@Rak Yes, I checked in merged manifest . But all activities/service/receiver tags has android:exported in it.

The following steps worked for me and hope it works for you too. Cheers!
• Downgrade targetSdkVersion from 31 to 30
• Open AndroidManifest.xml and tap on “Merged Manifest” tab at the bottom. More info https://developer.android.com/studio/build/manage-manifests#inspect_the_merged_manifest_and_find_conflicts.
• Check the merged manifest file for any missing android:exported attribute.
• Add android:exported anywhere that’s applicable.
• If the missing attribute is not in your codebase’s AndroidManifest.xml but in a dependency’s AndroidManifest.xml , update the dependency version.
• Now upgrade the targetSdkVersion to 31 and compile your app.
Here is one dependencies I had to update to support this migration.
• androidx.testrules

Hey @Priya, I tried downgrading targetSdkVersion to 30 and checked AndroidManifest file. But I found no missing android:exported attribute.

I'll also try upgrading the above mentioned dependency

Did you check in your app’s “merged manifest” file? As shown here at the bottom tab https://developer.android.com/studio/build/manage-manifests#inspect_the_merged_manifest_and_find_conflicts.

[Akhil Jain]

I have checked in merged manifest file present in bottom tab but haven't gone through one present in below mentioned directory. I'll verify that also

Hey mate! Is there any update on that? Could you fix it?
