Pending Intents - Android@8 - API Level 31

[Flor Guzman]

@chemerisuk

This plugin was integrated a while ago on IONIC3+Cordova project. And recently we upgraded from API LEVEL 30 to 31

Unfortunately I am getting the PendingIntent FLAG_IMMUTABLE error required which is making the app crash on push notification sent and app is Background. Foreground push notification is working as expected.

Error Android:
... stack trace**:java.lang.IllegalArgumentException:** app: **Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.

Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.**

@florgb02 try to upgrade to the latest version of the plugin. I don't think v4.4.2 supports android 30-31.

Thanks @chemerisuk unfortunately we can't upgrade at the moment but I was able to patch the plugin to target firebase.messaging version 23.0.0 and support for :firebase-iid:21.1.0 Both contain fixes to support PendingIntent FLAG_MUTABLE and FLAG_IMMUTABLE
Adding:
<framework src="com.google.firebase:firebase-messaging:23.0.0" />
<framework src="com.google.firebase:firebase-iid:21.1.0" />
Thanks
