I'm still new to supabase so maybe I'm missing something basic here... but I'm trying to implement auth via OTP and that works when I do

supabase.auth
        .verifyEmailOtp(type = OtpType.Email.EMAIL, email = "email", token = "123456")

    val session = supabase.auth.currentSessionOrNull()

    println(session) //session is a valid object. hooray!

but then if I just restart my app and call

val session = supabase.auth.currentSessionOrNull()
    println(session) //session is null

then i just get a null session. shouldn't my session persist?

[Colton Idle]

in firebase, my session would persist in this case. i dont need to persist any auth tokens or anything. am i understanding something wrong here?

[Jan]

It does persist, but probably by the time you print out the session, it hasn't been loaded yet. (Loading is basically instant, but you can still try to access auth before)
Either collect the sessionStatus flow and show a loading screen if the status is LoadingFromStorage/Initializing or just use Auth#awaitInitialization() . After that the session should be there.

[Colton Idle]

Hm. I'm doing it via a click listener so I would expect it to be there like a second after loading the app. Let me try again!

[Jan]

Yea, also debug logs would also be helpful, as they show the loading process

[Colton Idle]

Cool. Let me reorganize this code really quick. Its literally like 10 lines of compose + supabase code and see if I can get to the bottom of it!

[Colton Idle]

Interesting. That seemed to indeed work.

152226.384 I Trying to load latest session from storage.
152226.384 I null
152226.439 I Successfully loaded session from storage!
152230.972 I UserSession(accessToken=eyJhbG...

[Colton Idle]

Ah. I found the issue

fun logSesh() {
    val session = supabase.auth.currentSessionOrNull()
    println(session)
}

is my code. and it doesn't try to load latest session from storage until I call the above method

[Colton Idle]

so if i call the above method twice then I get auth

[Colton Idle]

val supabase = createSupabaseClient(
    supabaseUrl = "asdf",
    supabaseKey = "fdas"
) {
    install(Auth)
}

I thought ^ code would start my session

[Colton Idle]

But I guess after I install(Auth) I should also call supabase.auth.currentSessionOrNull()

[Colton Idle]

to init session

[Jan]

I thought ^ code would start my session

Well, it should. supabase.auth.currentSessionOrNull() is only short for (sessionStatus as? SessionStatus.Authenticated)?.session , so the method it self doesn't really do anything

[Colton Idle]

interesting. i wonder why

val supabase = createSupabaseClient(
supabaseUrl = "asdf",
supabaseKey = "fdas"
) {
install(Auth)
}

doesn't start my session

[Colton Idle]

I'm using "io.github.jan-tennert.supabasebom3.0.0-beta-1". maybe its a 3.0 bug.

[Jan]

Do you see no loading related logs without currentSessionOrNull ?

[Colton Idle]

Correct

[Colton Idle]

So if I have already logged in. and then just delete my entire app (10 lines) I'm left with this

val supabase = createSupabaseClient(
    supabaseUrl = "asdf",
    supabaseKey = "zxcv"
) {
    install(Auth)
    println("got here")
}

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            Supabase1Theme {
            }
        }
    }
}

which gives me these logs

---------------------------- PROCESS STARTED (16449) for package com.example.supabase1 ----------------------------
163117.352 W A resource failed to call close.
163117.352 W A resource failed to call close.
163121.903 D Installing profile for com.example.supabase1

[Jan]

Hmm, I just created a blank project which is basically the same:

val supabase = createSupabaseClient(
    supabaseUrl = "",
    supabaseKey = ""
) {
    defaultLogLevel = LogLevel.DEBUG //shouldn't matter as the loading logs are on the INFO level
    install(Auth)
    println("got here")
}


class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            MyApplicationTheme {
                Scaffold(modifier = Modifier.fillMaxSize()) { innerPadding ->
                    Greeting(
                        name = "Android",
                        modifier = Modifier.padding(innerPadding)
                    )
                }
            }
        }
    }
}

And I get these logs (after logging in before restart):
2024-09-20 225543.483 6829-6866 Supabase-Auth com.example.myapplication I Successfully loaded session from storage!
2024-09-20 225543.513 6829-6865 Supabase-Auth com.example.myapplication D Session found, auto refresh started

[Colton Idle]

Soooo weird. lemme try a clean install

[Colton Idle]

hm. i think maybe the creation is deffered

[Colton Idle]

If I do

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            Supabase1Theme {
                supabase
            }
        }
    }
}

[Colton Idle]

then it works

[Colton Idle]

i thought kotlin would create that variable right away. which now im confused why it doesn't.

Okay I think Android does some weird optimization stuff. If I remove my Compose code, so that only that stays:

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            MyApplicationTheme {
                
            }
        }
    }
}

It also appears to stop working.

[Colton Idle]

👀

[Colton Idle]

this... makes me question everything. lol

[Jan]

The session loading on Android gets triggered when the app starts via a lifecycle observer, maybe because nothing happens in the onCreate somehow these aren't getting triggered?

[Jan]

Weird bug, but at least we know that probably never occurs

[Colton Idle]

Weird. I updated to

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            Supabase1Theme {
                Scaffold(modifier = Modifier.fillMaxSize()) { innerPadding ->
                    Button({}) {
                        Text("Test")
                    }
                    Text("Test")
                    Text("Test")
                    Text("Test")
                    Text("Test")
                    Text("Test")
                    Text("Test")
                    Text("Test")
                    Text("Test")
                }
            }
        }
    }
}

and it still doesn't get called

[Jan]

Okay I really have no idea. That works:

MyApplicationTheme {
    Scaffold(modifier = Modifier.fillMaxSize()) { innerPadding ->
        Greeting(
            name = "Android",
            modifier = Modifier.padding(innerPadding)
        )
    }
}

That doesn't:

MyApplicationTheme {
    Text("test")
}

But calling supabase does fix it:

MyApplicationTheme {
    val status by supabase.auth.sessionStatus.collectAsState()
    Text("test")
}

[Colton Idle]

glad we resolved it in #C0B8MA7FA 😅

Thanks @Jan

[Jan]

Yep, no problem!
