Issues installing NuGet package v2.2.1 for Android

Follow

Hi Daniel,

Would you be able to send us the full logs you have from Visual Studio that shows that error? We can take that and investigate further to see if we can find a solution for you.

I'm having the same issue as Daniel. Is there a solution for this? Here are my logs...

Hi ,

What version of Visual Studio are you running? Additionally, are you running the latest Xamarin and Nuget and downloaded the latest Urban Airship component(3.1.1)?

Visual Studio version is 14.0.25431.01 Update 3

I am running the latest Xamarin version 4.2.1.64

I can't download the latest UrbanAirship package because this is a Xamarin Forms application. The Xamarin Forms package has a dependency on Xamarin.Android.Support.v4 of 23.3.0. I have to go back to the UrbanAirship package 2.2.1 to be compatible with the Xamarin Forms limitation.

Xamarin forms shouldn't have anything to do with it not working. Does it work on a non-Xamarin Forms app?

I'm able to add the SDK without using the Nuget Package Manager, so it could perhaps be a problem with Nuget.

Here is my package list. With this package list and before I add the urbanairship 2.2.1 dll the application runs perfectly.

<packages>
  <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Design" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v4" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.AppCompat" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.CardView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.MediaRouter" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.RecyclerView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Forms" version="2.3.3.175" targetFramework="monoandroid60" />
  <package id="Xamarin.GooglePlayServices.Base" version="29.0.0.2" targetFramework="monoandroid60" />
  <package id="Xamarin.GooglePlayServices.Basement" version="29.0.0.2" targetFramework="monoandroid60" />
  <package id="Xamarin.GooglePlayServices.Gcm" version="29.0.0.2" targetFramework="monoandroid60" />
  <package id="Xamarin.GooglePlayServices.Measurement" version="29.0.0.2" targetFramework="monoandroid60" />
</packages>

I then add a reference to the urbanairship.dll for the 2.2.1 SDK (Not using the NuGet)

urbanairship-2.2.1\lib\android/AirshipBindings.dll

The app still builds without error, but now when I go to run the app won't launch on the device. The output debug window gives me this message:

After you've added the .dll to the Xamarin Forms app, are you also ensuring that the AirshipConfig.properties file is properly filled in with the appropriate info?

What does the AndroidManifest.xml file look like after you've added the .dll for Urban Airship?

Thanks for your help. It's working now, but I'm not sure why. I filled in a package name in the manifest, ran it and it worked. I tried it again with the package name empty and it still worked. I guess it just needed a little help finding its way. I haven't got to the point where I have tested notifications yet though. I've just been trying to get the app to run with the urbanairship reference. Thanks again for your assistance.

No problem! Let us know if you run into any other issues.
