Simple getting started tutorial

[karussell]

See the tutorial here. Here we collect some of the issues.

• The sonatype snapshort repo is missing in build.gradle under "allprojects": maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
• the emulator does not seem to work
• Under linux I get

com.android.ddmlib.AdbCommandRejectedException: insufficient permissions for device: user in plugdev group; are your udev rules wrong?
 See [http://developer.android.com/tools/device.html] for more information
 Error while Installing APK

[karussell]

I fixed the linux problem via:

sudo apt-get install adb
sudo adb kill-server
sudo adb start-server
# now reconnecting the device

[boldtrn]

the emulator does not seem to work

Yes, I usually a hardware device to run it. I only had bad experiences with the emulator (also in other projects).

I'm getting below error while building the project. Can you please take a look?

You should be able to fix this by adding maven { url "https://oss.sonatype.org/content/repositories/snapshots" } in a new line here.

[ahamed-musthafa]

Excellent, it works! Thanks a lot for super quick response.

[karussell]

There is issue #27 happening for me when installing this from IDE. @boldtrn you said

For now this is fixed by passing the gh key as Mapbox key to the Navigation SDK

Can you outline where exactly the change is necessary?

[mapotu26]

When trying to clone the project, I get an error in the "Events" section of Android Studio once installed. The error is: "Cannot run Git". File not found:git.exe. Please help :) I copied the link and rewrote it myself and still the same error

[boldtrn]

@mapotu26 you will need to install git. This seems completely unrelated to this project. For relevant question, please let us know in our forum.

in the README.md is says:

Note: while it's possible to use raster tiles, we recommend vector tiles for mobile applications.

But in the tutorial it does not mention it.

Is there a way to use raster tiles like https://a.tile.openstreetmap.org/${z}/${x}/${y}.png ?

edit:
i guess it should work something like:
adding a style.json to assets with following content:
{ "version": 8, "sources": { "raster-tiles": { "type": "raster", "tiles": ["https://a.tile.openstreetmap.org/${z}/${x}/${y}.png "], "tileSize": 256 } }, "layers": [{ "id": "simple-tiles", "type": "raster", "source": "raster-tiles", "minzoom": 0, "maxzoom": 22 } ] }

and than setting in developer-config.xml
<string name="map_view_styleUrl" translatable="false">file:///android_asset/style.json</string>

but i get the error

loading style failed:

and no tiles are loaded

[boldtrn]

Something like this should work:

style: {
"version": 8,
"sources": {
"raster-tiles": {
"type": "raster",
"tiles": ["https://stamen-tiles.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.jpg"],
"tileSize": 256,
"attribution": 'Map tiles by <a target="_top" rel="noopener" href="http://stamen.com">Stamen Design</a>, under <a target="_top" rel="noopener" href="http://creativecommons.org/licenses/by/3.0">CC BY 3.0</a>.

}
},
"layers": [{
"id": "simple-tiles",
"type": "raster",
"source": "raster-tiles",
"minzoom": 0,
"maxzoom": 22
}]
}

[DakastaKay]

Something like this should work:

style: {
"version": 8,
"sources": {
"raster-tiles": {
"type": "raster",
"tiles": ["https://stamen-tiles.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.jpg"],
"tileSize": 256,
"attribution": 'Map tiles by <a target="_top" rel="noopener" href="http://stamen.com">Stamen Design</a>, under <a target="_top" rel="noopener" href="http://creativecommons.org/licenses/by/3.0">CC BY 3.0</a>.

}
},
"layers": [{
"id": "simple-tiles",
"type": "raster",
"source": "raster-tiles",
"minzoom": 0,
"maxzoom": 22
}]
}

Thank you for your input. It seems like the only difference to mine is the attributions line. I tested it and it still doesn't work. Any other suggestions? Thanks.

edit:

I tested some more and i get it to work with the url like:
"tiles": ["https://stamen-tiles.a.ssl.fastly.net/watercolor/{z}/{x}/{y}.jpg"],
and attribution like:
"attribution": "Map tiles by <a target=\"_top\" rel=\"noopener\" href=\"http://stamen.com\">Stamen Design</a>, under <a target=\"_top\" rel=\"noopener\" href=\"http://creativecommons.org/licenses/by/3.0\">CC BY 3.0</a>.

but only with the style.json on an external source on a web-server and not as asset with a url: file:///android_asset/style.json
