android-login-signup-tutorial's Issues

Registraction part is missing!

Is it just me or the signup part is missiong?

I just update the Api URL and I'm getting null reference error

Hello bro!
I just update the URL of the datasource:

class RemoteDataSource {
    companion object {
        private const val BASE_URL = "http://192.168.0.4:5000/api/user/"
    }

This my AuthApi:


 @POST("login")
    suspend fun login(
        @Field("email") email: String,
        @Field("password") password: String
    ) : LoginResponse

Therefore to test this endpoit it should be: http://192.168.0.4:5000/api/user/login
ok this works using Posman and this is my output:

{
    "user": {
        "id": "60760126e34a1d3668a264ac",
        "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJfaWQiOiI2MDc2MDEyNmUzNGExZDM2NjhhMjY0YWMiLCJpYXQiOjE2MTgzNTQ1MzV9.VPRoCntI6uC4bOmaB9A9mVvzY8CSUxxS7VVB1W91KUI",
        "name": "Freddy Aal",
        "phone": "942912222",
        "email": "[email protected]",
        "created_at": "2021-04-13T20:37:58.123Z"
    }
}

I updated the class User according to my Output:

data class User(
    val id: String,
    val access_token: String?,
    val name: String,
    val phone: String,
    val email: String,
    val created_at: String
)

But when I run the project and test it.. always with a correct credentials or wrong credentials it always throw this error:

java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String net.simplifiedcoding.data.responses.User.getAccess_token()' on a null object reference
