This bug is preventing our app from using GCM properly, and thus our customers from using our app.
Any help is greatly appreciated.
Thank you in advance.
I have similar error, GCM not working correctly and get a crash the first time to open the app.
The sample app crashes because the Build Action of GoogleService-Info.plist is set as "EmbeddedResource" and not as "BundleResource". Once you set it as BundleResoure, make a clean and build and everything works ok.
This step is specified on Getting Started page of GMC component:
>> 7. Add GoogleService-Info.plist to your Xamarin.iOS app project and set the Build Action to BundleResource
About the customer sample:
I cannot download the customer sample to see if the problem is the same, seems that iOS link is broken.
@IsraelSoto. I know, the problem isn't GoogleService-Info.plist.
The problem is the first time to run the app, app crash. So it's not resolved, I have this problem.
+[NSData gtm_dataByGzippingData:]: unrecognized selector sent to class 0x39060214
<GMR/ERROR> Exception on worker queue: +[NSData gtm_dataByGzippingData:]: unrecognized selector sent to class 0x39060214
The link is working, but it is an enterprise distribution app link so it is not a direct download link from a browser as a file. It will download on a ios device and install the app.
and as you can see from the url that is pointing to a manifest file (AppinuxCare.plist)
Which direct url is https://care.appinux.com/appinuxcare/3.0.2415/ios/AppinuxCare.plist (if you want to investigate it in a browser or text editor)
which in turn points to the ipa file located at
You can download this directly on the ios device.
Please note that this specific build is ARM7 only.
You are however correct in your observation that in the build 2415 the project file contains this
<BundleResource Include="GoogleService-Info.plist" />
It should be noted through that I have tried locally to change this and install and test, that did not make any difference
But I will be happy to make a new build with this change
I see that the status is set to Resolved, that is not correct in our view. This is a blocking problem for us and we have spent the better part of a week trying to fix this specific problem and it is still blocking us.
Please consider changing the status to in progress
I need an isolated test case with the problem. I tried to reproduce your error on GCM sample but with no success. Here is a test:
I also installed your app and, as you said, it crashes the first time, but without a code I have no tools to help you to find the error.
We are working on disassembling the relevant part of the app to give you a fairly isolated test cast. I expect that we will have a code sample uploaded today (maybe not entirely as isolated as we would like but I guess good enough. After all this is only the AppDelegate that is in play really.
In the meantime we have another Xamarin user apparently experiencing the same
I have now more or less managed to remove the MVVMCross Android project and removed a few 1000 files from the project and trimmed it down best I can
The bug is still happening, but the sample is 25MB with libs so I am sending a link to the 7zip file instead. All bin and obj folders have been removed.
Since it is an enterprise distribution app you will need to approve the developer the first time.
So steps to reproduce is
1. Build the app locally (you may need to change from ARM64 to ARM7 - in the project file - or both depending on architecture of testing device)
2. Deploy app to device
3. When you start the app the first time you will see a black screen and you will get the notification dialog where you have to allow notifications for the app
4. When you click on you will get a error in the console, this will normally crash the app when we have a UI view showing. (But during my trimming I have removed most of the UIViews and are not showing any so now you just get the error)

Thank you in advance
@IsrealSoto Any update?
Since yesterday, I have been working on this but with no progress. As soon as I get something, I'll let you know.
With the help of Components team, we finally discover the error of GCM and it was not related with GCM but with Google.Core. A library was missing on Google Core that was using the `+[NSData gtm_dataByGzippingData:]` method in background, we added the missing library and your app started to work again the first time.
Here's the link to dll that has the missing library, so you can continue the work with your app:
Test it and if you find any issue with it, let us know please.
A big apology for the inconveniences that this cause to you.
Is this fix included in the latest component?
