Kotlin-android unresolved reference : queue

Question

I imported retrofi2.Callback and I still get this error unresolved reference: enqueue this is the code of the login class

  import android.content.Intent
  import android.support.v7.app.AppCompatActivity
  import android.os.Bundle
  import android.provider.ContactsContract
  import android.widget.Button
  import android.widget.EditText
  import android.widget.TextView
  import android.widget.Toast
  import com.cbmis.imageapp.Common.Common
  import com.cbmis.imageapp.Model.APIResponse
  import com.cbmis.imageapp.Remote.IMyAPI
  import kotlinx.android.synthetic.main.activity_login.*
  import retrofit2.Call
  import retrofit2.Callback
  import retrofit2.Response

class LoginActivity : AppCompatActivity() {

 internal lateinit var mService:IMyAPI
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_login)
    //initservice
    mService = Common.api

    //Event
 txtregister.setOnClickListener { startActivity(Intent(this@LoginActivity,RegisterActivity::class.java))
 finish()
 }
  btn_login.setOnClickListener { authentificateUser(findViewById<TextView>(R.id.email).text.toString(), findViewById<TextView>(R.id.password).text.toString()) }

    }



private fun authentificateUser(email: String, password: String) {

    mService.loginUser(email, password)
            .enqueue(object :Callback<APIResponse> {
                override fun onFailure(call: Call<APIResponse>?, t: Throwable?) {
                   Toast.makeText(this@LoginActivity,t!!.message,Toast.LENGTH_SHORT).show()
                }

                override fun onResponse(call: Call<APIResponse>?, response: Response<APIResponse>?) {
                    if (response!!.body()!!.error)
                        Toast.makeText(this@LoginActivity,response!!.body()!!.errr_msg,Toast.LENGTH_SHORT).show()
                    else
                        Toast.makeText(this@LoginActivity, "Login Success!",Toast.LENGTH_SHORT).show()

                }

         })
}

}

and this is the interface/

interface IMyAPI {
@FormUrlEncoded
@POST("signup.php")
fun registerUser(@Field("email") email:String,@Field("name")name:String,@Field("password") password:String,@Field("dateofbirth") dateofbirth:String,@Field("genderM") genderM:String,@Field("genderF") genderF:String):Class<APIResponse>

@FormUrlEncoded
@POST("login.php")
fun loginUser(@Field("email") email:String,@Field("password") password:String):Class<APIResponse>

}

Any solutions can be proposed to solve this problem

First, you should post your code as text instead of an image. Second, could you show the declaration of the loginUser method? — zsmb13

You should be returning a Retrofit Call from your API's functions:

interface IMyAPI {

    @FormUrlEncoded
    @POST("signup.php")
    fun registerUser(/* params */) : Call<APIResponse>


    @FormUrlEncoded
    @POST("login.php")
    fun loginUser(/* params */): Call<APIResponse>

}
