Starting with the next release in July, the Mapbox Mobile Maps SDK will use a new distribution model and an updated version of our core map renderer, Mapbox GL Native. The core rendering library used by the Mapbox Mobile Maps SDKs will be a proprietary build of Mapbox GL Native. The Mapbox Mobile Maps SDKs themselves remain open source under a BSD-2 license.

Moving to a proprietary build of Mapbox GL
With these new releases, the core Mapbox GL dependency will no longer be licensed under BSD-2 but will be a proprietary build and licensed under the Mapbox Terms of Service.
…
Tasks.org uses Mapbox Maps, and it turns out I’ve been shipping a non-free transitive dependency since April. I assumed the licensing was a mistake (mapbox-gl-native-android #316), but now I see that it was not. I’m going to downgrade the Mapbox SDK to version 7.4.1 for the F-Droid build, which was the last release without mapbox-accounts-android
In case anyone is interested in using the current version of mapbox maps sdk without the proprietary dependency library, it’s actually rather easy:
exclude the mapbox-android-accounts module by adjusting the gradle dependencies:
dependencies {
implementation("com.mapbox.mapboxsdk:mapbox-android-sdk:9.2.1") {
exclude group: 'com.mapbox.mapboxsdk', module: 'mapbox-android-accounts'
}
// If you are using additional mapbox dependencies, you also need to exclude the module in them
implementation("com.mapbox.mapboxsdk:mapbox-android-plugin-annotation-v9:0.8.0") {
exclude group: 'com.mapbox.mapboxsdk', module: 'mapbox-android-accounts'
}
}
Make sure that ./gradle dependencies no longer shows the mapbox-android-accounts module.
Create a new file in your source code com/mapbox/android/accounts/v1/MapboxAccounts.java (I’m considering making it a little maven library for easier inclusion), with following content:
package com.mapbox.android.accounts.v1;
import java.util.UUID;
/**
* This class is used from within the Mapbox library
*/
@SuppressWarnings("unused")
public class MapboxAccounts {
public final static String SKU_ID_MAPS_MAUS = "00";
private final static String MAPS_SKU_PREFIX = "100";
/**
* Generates random UUID without hyphens
*/
public static String obtainEndUserId() {
String uuid = UUID.randomUUID().toString();
return uuid.substring(0, 8) + uuid.substring(9, 13) + uuid.substring(14, 18) + uuid.substring(19, 23) + uuid.substring(24, 36);
}
/**
* Generates a SKU which is the user id prefixed with 100 and base-36 encoded timestamp
*/
public static String obtainMapsSkuUserToken(String userId) {
String stamp = Long.toString(System.currentTimeMillis(), 36);
return MAPS_SKU_PREFIX + stamp + userId;
}
}
That’s all I needed to make it work without the proprietary library.
One issue is that the AccountsManager class that references MapboxAccounts has the following comment:
/**
* REMOVAL OR MODIFICATION OF THE FOLLOWING CODE VIOLATES THE MAPBOX TERMS
* OF SERVICE
* <p>
* The following code is used to access Mapbox's Mapping APIs.
* <p>
* Removal or modification of this code when used with Mapbox's Mapping APIs
* can result in termination of your agreement and/or your account with
* Mapbox.
...
The motivation for that note is that with the rights edits to AccountsManager you can probably trick their billing server into thinking that multiple users/devices are only one, effectively reducing your costs when using their service. This is not the case with the changes I suggested.
