My app is working without linking. It works fine also when I choose Sdk Assemblies only. It works fine in debug mode as well but it start failing if I choose linking SDk and UserAssemblies. I checked the logs and i find only what is below. I google all around for android, xamarin.android erros and people are talking about using Frames. I dont use any android native code. there is no frame defined in my android project. i am not sure if that is xamarin.forms producing but Can you please help me how to solve this problem?
there are similar questions like below. I already went through them no answer looks like related to my one. Even when I google "android.support.v7.widget.FitWindowsFrameLayout", I dont find any error about it. what is this class for? I am not referring to it all.
Error indicates me about line number 23 and I check the 23 in my manifest, there I have the line <receiver android:name="com.onesignal.NotificationOpenedReceiver" />. I excluded it and tried, error didnt change. Please lead me where should I look, if you need more information, I am going to update this question.

Try change ProGuard configuration.
I found great article with ProGuard configuration which fixes the missing "android.support.v7.widget.FitWindowsFrameLayout" problem ("Solution 2: ProGuard" in the article):
http://shaneneuville.com/firebase/proguard/2017/06/17/firebase-proguard-fun.html
ProGuard configuration from article:
-keep class com.google.android.gms.** { *; }
-dontwarn com.google.android.gms.**
-keep class com.microsoft.windowsazure.messaging.** { *; }
-dontwarn com.microsoft.windowsazure.messaging.**
-keep class com.google.firebase.** { *; }
-dontwarn com.google.firebase.**
-keep class android.support.v7.widget.** { *; }
-dontwarn android.support.v7.widget.**
-keep class android.support.v4.widget.Space { *; }
-dontwarn android.support.v4.widget.Space
You should clean solution after any ProGuard configuration changes.

Try to exclude Android.Support v7 and v4 from the linker.
In XamarinStudio: Project Options -> Android Build -> Linker -> Ignore assemblies
add Xamarin.Android.Support.v7.AppCompat;Xamarin.Android.Support.v4
40
It's stripped by the linker so you can "trick it " and simulate a false usage like this :
static bool falseflag = false;
static LinkerPleaseInclude()
{
if (falseflag)
{
var ignore = new FitWindowsFrameLayout(Application.Context);
}
}
This is available in the Xamarin documentation too : https://developer.xamarin.com/guides/android/advanced_topics/linking/
