QUESTION
I want to add firebase realtime database in my application but when I add a library for Firebase.Xamarin, it gives the error like
Severity Code Description Project File Line Suppression State Error Package Firebase.Xamarin 0.3.6 is not compatible with monoandroid81 (MonoAndroid,Version=v8.1). Package Firebase.Xamarin 0.3.6 supports: net (.NETFramework,Version=v0.0) 0
how can I solve this error, I tried to change the target version of application but it is not working. Please help me to solve this error.
...ANSWER
Answered 2018-Jul-30 at 12:48You are trying to install Firebase.Xamarin
which is published by an author named Ricardo. What you are probably looking for is the official packages published by Xamarin.
In this case they all start with Xamarin.Firebase
.
QUESTION
In my Xamarin project I'm using ReactiveUI and Firebase.Xamarin. When these two libraries are being used at once, any attempt to use System.Reactive.Linq.Observable
extension methods such as Where
or Select
results in compile time error:
The call is ambiguous between the following methods or properties: 'System.Reactive.Linq.Observable.Where(System.IObservable, System.Func)' and 'System.Reactive.Linq.Observable.Where(System.IObservable, System.Func)'
I presume this is being caused by both of these libraries defining/referencing the same methods in same namespaces. How can I fix that?
...ANSWER
Answered 2018-Sep-21 at 14:17It is likely that you are loading more than one version of the assembly that defines that namespace. It may be that the assemblies that you refer to load a common dependency. If they load different versions of that assembly you would get this error.
Ensure that you are using versions of the two libraries that depend on the same version of the dependant assembly.
QUESTION
Hello everyone I am trying to use Firebase in Xamarin.Forms. I am using this library by Ricardo. Till now I am able to get,put,post data without Authentication. Also able to get event realtime as data change. But I am stuck with Post data with authentication. This is my code--
var firebase = new FirebaseClient("https://XXXXXX-bdded.firebaseio.com/test");
var authProvider = new FirebaseAuthProvider(new FirebaseConfig("AIzaxxxxxxxxxxxxxxXE"));
var auth = await authProvider.SignInWithEmailAndPasswordAsync("pal@gmail.com", "abc@1234");
var item =await firebase
.Child("MyMeetings")
.WithAuth(auth.FirebaseToken)
.PostAsync("Please Post me");
DATABASE Rules are:-
{
"rules": {
"test":{
"$uid": {
".read": "auth.uid == $uid",
".write": "auth.uid == $uid",
}
}
}
}
It's throwing 401 unauthorized error. Please help me out.

Answered 2017-May-26 at 13:08I forgot to see in the issues of that git library it is mentioned there.
Just pass false as second parameter to PostAsync() like this - var item = await FirebaseClient
.Child("someTable")
.WithAuth(Auth.FirebaseToken)
.PostAsync(someObject, false);
QUESTION
My query returns a list of FirebaseObjects:
...ANSWER
Answered 2017-May-16 at 14:12Your query returns a list of object because you are querying a main node without adding any filter. That's "the same" as saying
QUESTION
I have a list of Objects that I get from Realtime-Database (Firebase) with a wrapper in C# Firebase.Xamarin
...ANSWER
Answered 2017-Jan-22 at 18:22First I would recommend getting rid of the foreach/Add
, it is the work for Select
