I am trying to test out the new Google SDK for iOS using the GoogleMapsSample on GitHub, however, every time I run the app crashes trying to create an instance of GMSMapView. This is happening when trying to run on both the simulator and the device.

I have enabled the SDK from the developer console and updated the GMSServices.ProvideAPIKey call to use my iOS API key, from what I have read that is pretty much all that's required?

I did notice this bug which was logged against the actual SDK which mentions an issue relating to OpenGL so not sure if that's what the issue is here. However, as I can't get access to a log using the simulator I ran it on the device and checked the log out using XCode and the error does seem to relate to this - stack trace:

  • Are you able to also get the console log from the XCode organizer? Can you symbolicate the crash report? Your crash seems to be happening in dyld (while loading libraries), whereas that bug report has the crash happening while rendering, so it is possibly a different issue. – Saxon Druce Feb 23 '13 at 00:13
  • @SaxonDruce this error was extracted from the console, this wasn't take from the device logs (as I am not getting one). The error does stem longer than what I have posted but I thought this was the most important part. I will run it again and add the full error. Also, not sure how I could get this symbolicated given its taken from the console? I get the feeling the DLL loading is a red herring because its only when I create an instance of GMSMapView it fails, I can create the camera etc and the app runs. – James Feb 23 '13 at 10:22
  • @SaxonDruce I have updated the stack trace to show the full log (excluding the binary images part - not sure that's relevant). I have also manually symbolicated any lines which were called from the sample app using the approach outlined [in this question](http://stackoverflow.com/questions/1460892/symbolicating-iphone-app-crash-reports). – James Feb 23 '13 at 11:45
  • Just wondering if you're using version 1.0.1 or 1.1.0 of the Google SDK? – Saxon Druce Feb 23 '13 at 11:50
  • @SaxonDruce not sure, I am running the sample linked to from [this Xamarin blog article](http://blog.xamarin.com/google-maps-sdk-for-ios-now-on-monotouch/) - specifically the *"download the bindings library"*. – James Feb 23 '13 at 11:55
  • @SaxonDruce looking at the github repository, it does appear to be 1.0.1. I will try running the latest version and see if the error persists. – James Feb 23 '13 at 12:03
  • Yeah I think it would be 1.0.1, since that was the only version available on the 14th of December when that blog post was made. The reason I asked is that I think the mono bindings wouldn't be compatible with 1.1.0, if that was what you were using (since the API changed a bit between 1.0.1 and 1.0.2, and again for 1.1.0). – Saxon Druce Feb 23 '13 at 12:08
  • I'm downloading the bindings as we speak so I will rebuild using the latest version. I will let you know if it works. – James Feb 23 '13 at 12:11
  • You'll probably need to make a few changes to the binding. At a minimum, GMSCamera (a C struct) was removed and replaced with GMSCameraPosition (an Objective-C class). – Saxon Druce Feb 23 '13 at 12:14
  • What's curious about your crash report is that it's crashing in thread 2 (which is the background thread which downloads tiles from the server). I'm not sure why it would crash there - or why the main thread would be somewhere in dyld when the background thread is trying to fetch tiles. – Saxon Druce Feb 23 '13 at 12:16
  • @SaxonDruce tried updating the existing bindings to use `GMSCameraPosition` instead of `GMSCamera` still crashing though. Getting a more readable stack trace now relating to `GMSMapView.FromCamera` which takes in a `RectangleF` and `GMSCameraPosition`. I have never updating bindings before but I followed the [documentation](http://docs.xamarin.com/guides/ios/advanced_topics/binding_objective-c_libraries) so not sure if I have done something wrong! – James Feb 23 '13 at 20:13
  • @James: you should try to get a fully symbolicated crash report from Xcode's Organizer (just plug in the device in your Mac, open Xcode, Window -> Organizer, pick your device on the left and then the Device Log node - note that Xcode will symbolicate in the background while you're viewing the crash report, it may take a few seconds to complete). – Rolf Bjarne Kvinge Feb 26 '13 at 23:02
  • @RolfBjarneKvinge that's what I usually check however this particular app wasn't creating one. Not sure if the app has to start before it creates one? I will check again and update my post if there is one there. Is there nothing from the log I posted of use? – James Feb 26 '13 at 23:21
  • Updated bindings :) see below – dalexsoto Feb 27 '13 at 07:05
  • @James: The log says: ": Not saving crash log because we have reached the limit for logs to store on disk. Sync or otherwise clear logs from /var/mobile/Library/Logs/CrashReporter to save new logs." - you can fix this by syncing your device with iTunes. – Rolf Bjarne Kvinge Feb 27 '13 at 11:07
  • @RolfBjarneKvinge *completely* missed that, thanks! I am not at my machine but I will clear the logs when I get home and re-post the device log. dalexsoto has kindly updated the bindings for the latest version so I would most likely want to use them, however, it still might be worth finding out why this issue is happening. – James Feb 27 '13 at 11:42
  • @RolfBjarneKvinge see updated stack trace. – James Feb 27 '13 at 18:32
  • @James: An unhandled Objective-C exception is ending up terminating the process. Can you try adding "-v -v -v" (without the quotes) to the additional mtouch arguments in the project's iOS Build options page and then try again. You'll still crash, but another line should be printed to the device log with information about the Objective-C exception being thrown ("MonoTouch: Received unhandled ObjectiveC exception: ..."). – Rolf Bjarne Kvinge Feb 27 '13 at 21:27
  • @RolfBjarneKvinge I actually deleted the old bindings but I will try to find an old copy of the dll and try again. In the mean time, I have downloaded the new bindings and it's working fine in the simulator but when I go to deploy to the device I get - `Undefined symbols for architecture armv7: "_WebPInitPremultiplyNEON", referenced from: _GMSx_WebPInitPremultiply in GoogleMaps(libWebP.o) "_WebPInitUpsamplersNEON", referenced from: _GMSx_WebPInitUpsamplers in GoogleMaps(libWebP.o) ld: symbol(s) not found for architecture armv7 collect2: ld returned 1 exit status` - any ideas? – James Feb 27 '13 at 21:31
  • @RolfBjarneKvinge got this - `MonoTouch: Received unhandled ObjectiveC exception: NSInternalInconsistencyException +entityForName: could not locate an NSManagedObjectModel for entity name 'GMSCachedTile'`. – James Feb 27 '13 at 21:40
  • @James: The problem with the latest bindings is Google's fault. I've filed a bug with them: http://code.google.com/p/gmaps-api-issues/issues/detail?id=5018 (please star it to make them fix it faster :) – Rolf Bjarne Kvinge Feb 27 '13 at 22:31
  • @James: if you google the "could not locate an NSManagedObjectModel for entity name 'GMSCachedTile'" message you'll find several ideas you can try out - it might be an issue with missing resources from their bundle. – Rolf Bjarne Kvinge Feb 27 '13 at 22:35
  • @RolfBjarneKvinge thought that, when I googled the actual error with regards to `Undefined symbols for architecture armv7` it did seem to suggest there was a missing lib somewhere. I have starred the issue hopefully they get it fixed ASAP as I would like to have the new map view in my app in time for an April release. – James Feb 27 '13 at 23:01

Update #2

Google suggested a workaround and it has been implemented. I have successfully deployed to device :) you can find the working solution on MonoTouch-Bindings Repo

Google will fix this on their upcoming release as stated here.

Happy Coding

Update

There is a bug on Google Maps that makes it impossible to use it in Xamarin.iOS, this bug has been reported to google here

http://code.google.com/p/gmaps-api-issues/issues/detail?id=5018

Please Star it so google notices and fixes it faster ;)

I have updated the bindings to version 1.1.0 of Google Maps you can find them here https://github.com/mono/monotouch-bindings/tree/master/GoogleMaps

Please note I have not updated the sample to reflect the Api changes yet.

Hope this helps

Alex

  • +1 brilliant! I will get this downloaded & tested as soon as I get a chance. – James Feb 27 '13 at 09:41
  • Just tried to deploy this to a device and got the following error: `Undefined symbols for architecture armv7: "_WebPInitPremultiplyNEON", referenced from: _GMSx_WebPInitPremultiply in GoogleMaps(libWebP.o) "_WebPInitUpsamplersNEON", referenced from: _GMSx_WebPInitUpsamplers in GoogleMaps(libWebP.o) ld: symbol(s) not found for architecture armv7 collect2: ld returned 1 exit status error MT5202: Native linking failed.

  • yeah was logged by Rolf (see comments on question). Oh and already got it starred and spreading the word! Thanks. – James Feb 28 '13 at 23:20

Xamarin did not update to the newer version since they did the last update on 14 december. I believe that this crash relates to this issue. Maybe the API keys you can generate today are just build for 1.1.0 and newer.

  • I would be shocked if it was the API key causing this type of exception (although I am not ruling it out). v1.0.2 is still available for download so it wouldn't make sense for the API key to only support v1.1.0 upwards. – James Feb 25 '13 at 13:17
