Native library binding - Mapbox #578
-
|
Mapbox is the best mapping library for outdoor adventure consumer-facing apps (think cycling, hiking, running). It uses vector-based tiles, that are faster to render, better for offline use cases, and have greater resolution than raster-based tiles used by Google maps. The Mapbox library is quite complex so creating bindings is a daunting task. In addition, they update their libraries often, so keeping up (dev + test) would be very time consuming. There has been one attempt at this, which stalled. Is it possible to leverage a native 3rd party UI-intensive control w/o developing and maintaining bindings? Pretty sure the answer is "no" for now, but wondering how a future version of Xamarin or .NET MAUI can solve this problem. Without this ability, the gold-standard in mapping is out of reach for Xamarin-based apps. As the author of Bicycle Route Navigator, we're at an inflection point on potentially rebuilding from Xamarin to native iOS and Android apps to leverage Mapbox. |

Any news concerning Mapbox? or even map solution regarding .NET MAUI? I saw some news about embedding a map in their roadmap (starting with Google Maps I guess) but that's was several months ago (I remember they said around december 2021 or Q1 2022)... |

I just want to write here that you can use Even if your whole app is written in XAML, you can use Performance-wise it's probably going to be a bit slower than an optimized native solution but I can confirm it's definitely a working solution. |

The problem is that for MapBox to work natively you need to create bindings for the official Android library (AAR or JAR). This process right now is quite difficult and not well documented (see the resources below) and you have to spend at least few days learning how to create these bindings. It's not a straightforward process because of differences between Java and C#. ...but if you learn it you give yourself freedom to use any Android library in your .NET MAUI project. ...or wait for some good soul that will do it for us and publish it :) I personally gave up trying to create the bindings for MapBox AAR and switched to Google maps for now. Beware that you probably need to create bindings not only for the MapBox AAR but also for its dependencies (which may or may not exist as NuGets). Resources for learning: |

Mapbox is great - but isn't the only game in town. ESRI's ArcGIS Runtime SDK supports most major platforms including XF and they have a preview out for MAUI: We've been building with their SDK for years and they do support vector tile basemaps, offline data collection/sync, routing, etc... In the past ESRI hasn't really had a very great understanding of the commercial app dev market, but they are improving and have some competitively priced developer plans that pencil out quite competitively with MapBox's offerings |

So the .gradle folder is under C:\Users<user>.gradle Hopefully this saves someone from a headache. Now I'm trying to figure out why my build is getting Could not resolve ... Received status code 401 from server: Unauthorized |

@tuyen-vuduc Hello, I also used the Mapbox.maui control you developed and ran into problems with the error code GDL001 Gradlew build failed D:\MAUIServer\MauiDataCenter\MauiDataCenter\obj\xgradle\gradlew.bat, I noticed that your development environment is on macOS, and my test platform is windows, I wonder if you can provide some help information, thank you |

Maybe you omit this step? Without adding gradle.properties inside .gradle home directory would not work. Also if you did that and still not working, inside .gradle/daemon/7.6 you should find some log files with more info that might help pinpoint the problem. |

Yes I did this by manually adding MAPBOX_DOWNLOADS_TOKEN to the.gradle.properties file. If added in the console there will be a null character after each character, thank you for your help |

I've managed to fix a similar error by setting JAVA_HOME env variable to path corresponding to jdk-19. There is a compatibility matrix between gradle version and Java versions and in my case I had Java 21 which is not compatible with gradle 7.6. If this doesn't fix the issue, you can also check inside .gradle folder, there should be a folder daemon which inside has logs for different versions. In those logs you can find more info |

On your system, in your home directory, you should find a .gradle folder and in that folder, either you already have a gradle.properties file or you create one. Either way, there you should put the mapbox token. You can find a detailed explanation here |

Read it again slowly and carefully. Plz check out Mapbox document as well for further info. |
