firebasex error: constructor Builder in class Builder cannot be applied to given types - ionic-framework

Question

I am making an Ionic app and I want to integrate cordova plugin firebase. Unfortunately, this plugin is not maintained anymore so I use a fork: firebasex.
When running "ionic cordova run android", I get the following error:
BUILD FAILED in 43s
C:\[...]\platforms\android\gradlew: Command failed with exit code 1 Error output:

Thanks for helping me.

Answer 1

For clarity and people just like me searching 'firebase-x boolean areNotificationsEnabled = notificationManagerCompat.areNotificationsEnabled();', the answer is #mobiemp 's comment re android v4.
Simply remove it:
# ionic users
ionic cordova plugin remove cordova-plugin-android-support-v4
# cordova users
cordova plugin remove cordova-plugin-android-support-v4
cordova clean android; # flush it out
# then use your run command again, ie
ionic cordova run android -lc --address=0.0.0.0;

you need to remove firebase plugin if it is still there... also you need to update firebasex... it will fix the problem... if it isn't then trying removing some deprecated plugins you will able to find out in which plugin the problem exists...
it is the problem with the plugin the error message indicating that point. the similar problem exists with other plugins and update of the plugin and removing of the plugin fix the error...
here is the reference
