build is failing though android:exported=true is being added to plugin.xml

[pankajjain15]

Hi

I have installed FCM plugin as per the instruction provided here

https://ionicframework.com/docs/native/fcm

I was getting the build error when I did ionic cordova build androind

I researched on this issue and found that , I have to add exported:true to the plugin.xml under node_modules\cordova-plugin-fcm-with-dependecy-updated

like below

But I am still facing the same issue. Kindly guide/advice

I faced the same issue recently. Try removing the Android platform, making changes to the plugin.xml and then re-adding the platform. These sequence of steps worked for me.

@briquetech I tried above steps lot of times but didn't worked for me. Don't know what is happening .

@pankajjain15

1. Remove your plugin
2. Add plugin as per this comment's instructions https://github.com/andrehtissot/cordova-plugin-fcm-with-dependecy-updated/issues/293#issuecomment-1377487961
3. Build
4. If build fails: Open \platforms\android\app\src\main\AndroidManifest.xml find "com.gae.scaffolder" add android:exported="true" to <activity and <service. Then try to build. Sometimes, multiple and will get added for "com.gae.scaffolder", in that case, you'll have to remove the extra ones. After this, the build should work.

This double entry will not go away even if you remove the additional entry. Next time you build, the duplicate entry will return.

One more thing you can most definitely do is to upgrade the gradle version. This will definitely rid you of the exported issue.

Hello @briquetech I have exactly the same problem as @flyingcat42, regarding the version of gradle you are talking about, I updated mine to 7.2, but I still have the same problem, which version can solve it definitively this issue ?
