Firebase common ver 22 is incompatible with Courier

[lance0428]

We were attempting to upgrade our Firebase version in our app today from 33.15.0 to 34.1.0. This new bom uses com.google.firebase:firebase-common:22 that includes changes for Google's initiative to move a lot of the ktx helpers into the main packages (more). It seems they have removed com.google.firebase.ktx.Firebase and they want you to use com.google.firebase.Firebase directly.

We are getting NoClassDefFoundError errors that are crashing our app.

@lance0428 thanks for reporting. We'll get a fix out shortly and follow up here.

@lance0428 still working on getting this right, more challenging than you'd think because all our dependencies work with 1.7.20 of kotlin. Latest firebase messaging requires 1.9.0 among other changes.

Figured I'd send an update.

@lance0428 we have a fix here, working on rolling it out shortly: #28

The biggest change is that we've removed our public dependency on Firebase Messaging. You will have to add FCM to your app, use a traditional FCM service, then add some Courier snippets.

Will update here when it's live.

@lance0428 before we go further with this, I had the idea to try a new test app and see if I can get the issue you're experiencing to happen.

In my testing, I am unable to reproduce it, though, I do know what your issue is.

Curious, in your build.gradle are you importing firebase-messaging?

If so, can you set your build gradle to be like this, run gradle sync and rerun your app?

implementation(platform(libs.firebase.bom))
implementation(libs.firebase.analytics)
implementation(libs.firebase.auth)
implementation(libs.firebase.firestore)
// implementation(libs.firebase.messaging) Please comment this out... this way, courier will not conflict with firebase messaging packages.

implementation(libs.courier.android)

Let me know how this goes please. Thanks!
