Android: use VTM OpenGL vector map library

[devemux86]

We released VTM 0.6.0 OpenGL vector map library. 🙂

Here is an update for Android sample, i.e. GraphHopper + VTM working together:

• Use VTM OpenGL renderer with offline Mapsforge vector maps
• Show its overlay API use for the routing markers and calculated route line

Really nice update - thanks a lot @devemux86 !

Probably you could update now the Android screenshot with something more OpenGL in 2.5D!

[karussell]

Do you know how the pom.xml snippet looks like with those native libs?

Yeah, tried this but I still rely on (old) Maven ;(

Can you try declaring the natives with the <classifier> tag, e.g.:

<classifier>natives-armeabi</classifier>

[karussell]

Thanks, that was it! Never heard about classifier, always thought the system path is the way to go, nice!

This is just wow :) ! Not only the rotation & tilt is nice but also the rendering speed!

And without an active file tile cache!
We can add it in the future for an even better experience. 🙂

Hmmh, tried a landscape screenshot but the text does not rotate. So I included for now a smaller screenshot but it does not look that pretty: https://github.com/graphhopper/graphhopper/blob/master/docs/android/index.md

(I removed the readme in the Android subproject - good idea or should we at least point to the android docs fromt here?)

Probably because app is locked for portrait?

Screenshot indeed should be a large one, at least HD.
Android subproject could use a docs link and the same screenshot, good for demonstration there too. 🙂

[karussell]

Ok, I'll try.

Problem of this dup info: I completely forgot about it ... I'll re-add a link to the docs + the screen.

[devemux86]

I'd replace that line with

android:configChanges="keyboardHidden|orientation|screenSize"

to avoid application restart with device orientation changes.

[karussell]

Nice, that improves it even more - thanks again!
