Why the firestore isn't working on android studio

Question

I try to implement firestore on my android project. I have follow everything on the official firebase wesbite. I am getting those errors :

I have implemented okhttp and put

<uses-permission android:name="android.permission.INTERNET"/>

on the manifest file. But nothing is working: the app is still crashing. Here is my code:

val userID = auth.currentUser
                db.collection("users").document(userID.toString())
                val Map = hashMapOf<String, Any>()
                Map["pseudo"] = name.toString()
                db.collection("users")
                        .add(Map)
                        .addOnSuccessListener { documentReference ->
                            Toast.makeText(baseContext, "succes:" + userID,
                                    Toast.LENGTH_SHORT).show()
                        }
                        .addOnFailureListener { e ->
                            Toast.makeText(baseContext, "Veuillez essayer plus tard.",
                                    Toast.LENGTH_SHORT).show()
                        }

(I have tried tu put String instead of the "Any" in the hashmap variable.) If anyone have a clue!

Answer 1

I experienced the same thing on android 11 and got around it by adding the following to my build.gradle file

implementation "io.grpc:grpc-okhttp:1.32.2"

Answer 2

as the below answer add in android/app/build.gradle in dependencies section

dependencies {
    ....
    .....
    implementation "io.grpc:grpc-okhttp:1.32.2"
}

Answer 3

I did try a solution from Joseph Geoffery

• Open build.gradle file in your app folder
• Add this in dependencies section

  implementation "io.grpc:grpc-okhttp:1.32.2"
  

this work for me
