I’m using Graphhopper in my android app (for personal use).
You did a wonderful job.
I’m stuck with version 0.6 for various reasons, but it’s ok for my needs.
I have only one problem: slow routing time for 500+ Km routes without CH due to android memory limitations.
I already searched forums and get some improvements using A* BI algo and increasing epsilon, but it’s still very slow in some cases, so I tried to go deeper.
After adding “largeHeap” in manifest on my P8 Lite (2015) with 2GB ram my app has max heap size = 512 MB.
forDesktop() improves performance, but causes OutOfMemoryError when allocated memory exceeds 512 MB.
With forMobile() allocated memory starts at 20 MB, grows really slow, it reaches about 50% of 512 MB and routing is still slow.
So my question is: is there a way to increase allocated memory size with MMAP / forMobile()?
Thanks in advance
