[Android] Logcat error "PIXEL: ioctl err: 1"

[ravenfeld]

Hello, I'm asking for your help because I don't understand the problem.
Everything works fine, but my logcat gets killed by this log "PIXEL: ioctl err: 1" every 12 ms
Do you have any tips on how to get rid of this problem?
I've run the dialing code but I have no other problems.

Thanks in advance

Hi @ravenfeld. Could you provide more detailed reproduction steps?

[ravenfeld]

I just touch the card or do nothing if the locationComponent is activated. It's as if animating the map is causing problems internally in the logcat.

On one plus 6 I don't have the message but GC requests

What version are you using?

Can you provide a minimal version of your code that recreates the problem?

Yes you can test the polygon example of this lib, or I thought it was to put in compose but even by redoing an application in xml same worry.

any updates on this @louwers ?
I also have this issue when including a map in a composable AndroidView especially when scrolling around on the map for instance.
This causes my phone to get really hot ...

For the moment no, I have the impression that it depends on the phones, some of which don't report the error.

I have not seen this issue myself (using Samsung S10 mostly). Please provide a way to reproduce the problem that does not depend on external libraries.

Also feel free to create a bug report instead of a discussion. Thanks!

I will come up with a minimal sample.
In the meantime as heads-up, I didn't observe this issue in emulator (Pixel 6 API 33 and Pixel 7 Pro API34)

Hey @louwers
I finally found the time to come up with a sample

You will find a lot of the ioctl errors when you pinch to zoom or dragging around the map.

class MainActivity : ComponentActivity() {

    private fun setUpMapLibre(okHttpClient: OkHttpClient) {
        Mapbox.getInstance(this, null, WellKnownTileServer.MapLibre)
        HttpRequestUtil.setOkHttpClient(okHttpClient)
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        val okHttpClient = OkHttpClient.Builder().build()
        setUpMapLibre(okHttpClient)

        super.onCreate(savedInstanceState)
        setContent {
            MaterialTheme {
                Surface(
                    modifier = Modifier.fillMaxSize(), color = MaterialTheme.colorScheme.background
                ) {
                    val context = LocalContext.current
                    val mapView = MapView(context).apply {
                        getMapAsync { map ->
                            map.apply {
                                setStyle("https://raw.githubusercontent.com/maplibre/demotiles/gh-pages/styles/osm-bright-gl-style/style.json") {
                                    LocationComponentActivationOptions.builder(context, it).build()
                                }
                            }
                        }
                    }
                    AndroidView(factory = { mapView })
                }
            }
        }
    }
}

PS: This is the most basic sample I could provide.
For the dependencies you need to include:
add this to your gradle.settings.kts

    implementation("org.maplibre.gl:android-sdk:10.2.0")
    implementation("org.maplibre.gl:android-plugin-annotation-v9:2.0.1")
    implementation("com.squareup.okhttp3:okhttp:4.11.0")

It even gets worse when updating the map with a location bubble or so by incorporation of location services and co.
as wished this is only the most basic sample app I could come up with
