Offline maps not generates without wifi connection April 10, 2021, 02:05:51 AM Hi,I'm using offline maps and I discovered, that these are not generated when I'm outside. Only previously generated (cached) tiles are show. But If I zoom in, I got blank map and tiles are not generated. But as soon as i come home, where I connect to wifi, tiles are generated. So it looks like there is some setting that prevent tiles generation without wifi.Is it possible or I miss something?
Re: Offline maps not generates without wifi connection Reply #1 – April 10, 2021, 09:41:24 AM I can't replicate that. Geooh is using Mapsforge software to render the offline map tiles and there is no dependency on the network. Mapsforge is using a tile cache so possibly blank tiles are being stored? I'll continue looking, but so far I'm not seeing a cause. See if you can determine a pattern and let me know.
Re: Offline maps not generates without wifi connection Reply #2 – April 10, 2021, 01:23:51 PM It looks like something crashed and maps are no more generated. I have to restart Geooh to make it work.This is how it looks like when I'm in terrain

Re: Offline maps not generates without wifi connection Reply #4 – April 10, 2021, 03:25:54 PM It seems like it happen after restore. I've now open Geooh, the restoring dialog was shown and after a while Geooh restored app - shown the map. Now when I move around and zoom, no new tiles are generated.
Re: Offline maps not generates without wifi connection Reply #5 – April 10, 2021, 04:07:05 PM Try moving your offline maps directory to a new location and then have Geooh point to it in settings. I've had someone report doing that before to fix a corrupted directory. Let me know if that corrects it.

Re: Offline maps not generates without wifi connection Reply #7 – May 04, 2021, 11:04:22 AM Sorry for late reply, we were not caching recently.I've made some tests. The issue is present on My and my Wife's phone as weell. The workaround I've found is exit Geooh, using several press of Back button, then open running applications list and swipe out Geooh, so app is completely terminated and unloaded from memory. Then after new start of Geooh, my offline maps works without issue, missing tiles are generated.How to reproduce:Open Geooh, make sure you are using offline mapsChoose listOpen map viewGo to unexplored area and check that tiles are generatedUse "Home" button to switch to desktopUse Memory hungry applications like Web browser so Geooh is unloaded from memory.Open Geooh againApplication restores and immediately switch to map view.Go to unexplored area, try different zooms - you should noticed blank tiles that are not renderingDo a workaround (exit Geooh, wipe it from memory)Start Geooh againGo to area with blank tiles, will be rendered this time.My guess is, that there is something wrong in the map view restore process. Seems like tiles rendering is not started, only cached tiles is shown.

Re: Offline maps not generates without wifi connection Reply #9 – May 04, 2021, 11:27:04 AM Thanks for the detail steps on how it occurs. My guess (as you think) the restore process is not reenabling some Mapsforge software component since it is their software that does offline maps. I'll dig further into that scenario.
Re: Offline maps not generates without wifi connection Reply #10 – May 04, 2021, 03:25:38 PM OK, I found the issue. It was what I thought where Mapsforge wasn't fully re-initialized after a restore of the app. I believe I have got it working correctly now. The next release will have the fix in it.Thanks again for letting me know how to replicate it. The detail information was just what I needed! 1 Likes
Re: Offline maps not generates without wifi connection Reply #11 – May 15, 2021, 08:36:48 AM So currently maps in lists does not work at all. Only #Live map is working.Morning I've opened map in my ValMez list. They worked correctly for a while. But then I've rotated display, map view rotated as well, but without map from that time. And I'm not able to make it work again. I've tried restart Geooh, restart phone, clear Geooh cache, but still no map, only white display. Later I've found, that the #Live map is working. But nothing more.I'm not sure if this is connected or it is a new issue as I've switched to a new phone Google Pixel 4a 5G with Android 11.
Re: Offline maps not generates without wifi connection Reply #12 – May 15, 2021, 10:27:08 AM I can't replicate that. All my offline lists show fine on an offline map.Does the map list (side drawer on map) show caches? Are they located in an area where there is no offline map? What does Google maps look like?You could send me the offline list exported and also your settings to see I can figure it out.
Re: Offline maps not generates without wifi connection Reply #13 – May 15, 2021, 01:03:07 PM It was probably connected with data transfer to new phone. I've deleted all app data, re-imported lists and map works again.False allarm. Sorry. 1 Likes
