Flutter MapBox Error - Unauthorized 401 error when building app for Android

Question

In my project I use mapbox_gl: ^0.14.0.

When running flutter build aar command it fails with:

FAILURE: Build failed with an exception.

BUILD FAILED in 1m 30s

Gradle task assembleAarDebug failed with exit code 1.

Also flutter doctor:

I think it's the problem with secret token since it gives me Unauthorized 401 from server.

I made sure that I put it in my global (not project) gradle.properties the secret key like this: MAPBOX_DOWNLOADS_TOKEN=sk.eyJ1Ij... I saw in another thread that maybe it should be MAPBOX_DOWNLOAD_TOKEN instead of MAPBOX_DOWNLOADS_TOKEN but it did not help.

My secret token has all PUBLIC SCOPES ticked and DOWNLOADS:READ ticked in SECRET SCOPES

So maybe my project simply not reading it but I don't know why.

Hello, Have you found any solution for that? I have the same issue arrive. — Rajesh, Feb 08 '22 at 09:17

You can find documentation of Mapbox GL for android here: https://docs.mapbox.com/android/maps/guides/install/.

As said by the mapbox_gl plugin developers, this is community driven not an official Mapbox product.

So, do only the https://docs.mapbox.com/android/maps/guides/install/#configure-credentials part of the documentation for the flutter android project.

Create a secret access token with the Downloads:Read scope.
Configure your secret token in android/gradle.properties as MAPBOX_DOWNLOADS_TOKEN=YOUR_SECRET_MAPBOX_ACCESS_TOKEN

Configure permissions in app/source/main/AndroidManifest.xml as:

<!-- Always include this permission -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

<!-- Include only if your app benefits from precise location access. -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Keep in mind to provide the same secret key in the accessToken property of the MapboxMap widget in your project.
