Android Native App Crash with Embeddinator generated AAR.
Steps to Reproduce
Tool used - Visual Studio for mac
-
create android class library and multiPlatform portable class library in visual studio for mac
-
create AAR file from this android library using command mono '${SolutionDir}/packages/Embeddinator-4000.0.4.0/tools/Embeddinator-4000.exe' '${TargetPath}' --gen=Java --platform=Android --outdir='${SolutionDir}/androidoutput' -c
-
use this AAR file in Android Native Application
-
This AAR file is creating a fragment using Content Page.
[Export("getPageFragment")] public Android.Support.V4.App.Fragment GetPageFragment(Context context) { if (!Forms.IsInitialized) { Forms.Init(context, null); } return new FormPage().CreateSupportFragment(context); }This fragment is launched from Native APP.
public class FormPage : ContentPage { public FormPage() { var button = new Button { Text = "Click Me Plugin2!", VerticalOptions = LayoutOptions.CenterAndExpand, HorizontalOptions = LayoutOptions.CenterAndExpand, };
int clicked = 0; button.Clicked += (s, e) => button.Text = "Clicked:Plugin2 " + clicked++; Content = button; }}
Expected Behavior
Native Android App should launch the xamain.form Page.
Actual Behavior
App is crashed when getPageFragment is called from Native App. Application is crashed when fragment is created.

Example Project (If Possible)
public class FormPage : ContentPage { public FormPage() { var button = new Button { Text = "Click Me Plugin2!", VerticalOptions = LayoutOptions.CenterAndExpand, HorizontalOptions = LayoutOptions.CenterAndExpand, };
int clicked = 0;
button.Clicked += (s, e) => button.Text = "Clicked:Plugin2 " + clicked++;

}
}
//////////helper class////////////// [Register("plugin.droid.Helper")] public class Helper : Java.Lang.Object { public Helper() : base() { }
public Helper(IntPtr handle, JniHandleOwnership transfer)

[Export("getPageFragment")]
public Android.Support.V4.App.Fragment GetPageFragment(Context context)
{
if (!Forms.IsInitialized) {
Forms.Init(context, null);
}
return new FormPage().CreateSupportFragment(context);
}
}
Now use this GetPageFragment API from Android Native APPl in MainActivity.java Helper helpers = new Helper(); Fragment frag = helpers.getPageFragment(MainActivity.this); Application is crashed when fragment is created.
@chamons There is a workaround for this. Add FormViewGroup.jar in android native Project after that it can launch xamarin.form page successfully. can you explain why Embeddinator is not adding support for this?
As I noted in another issue recently:
There currently is not active development by members of the Xamarin team, but we are triaging incoming issues and assisting where it makes sense.
As a community project, the hope is that people will be able to build upon it to bundle C# libraries in native libraries....
