Linker Exception in "Release" Android build

Open mrbelk opened this issue 7 years ago • 30 comments

Bug

We are using the XfxControls package in a Xamarin.Forms app (Droid and iOS). The Xamarin Forms version is 2.4.0.74863. When we try to compile our primary Droid platform project, we get a build error that the "LinkAssemblies task failed unexpectedly." The actual build error is quoted below. When we build the project in "Debug" mode, it works fine. If we select "Don't Link" in the Linker Behavior section of the Droid project options in the Release configuration, the build completes.

  • Version Number of Control: 1.1.3
  • Device Tested On: N/A
  • Simulator Tested On: N/A

Affects

  • [ ] iOS
  • [x] Android (Min version API21, target version API26, Xamarin Android version 8.1.0.25, SDK Tools version 25.2.5, SDK Platform Tools version 27.0.1, SDK Build Tools version 26.0.3)

Expected Behavior

Project compiles without any linker errors

Actual Behavior

Droid project compilation fails with linker exception like this:

Steps to reproduce the Behavior

mrbelk avatar Jan 04 '18 14:01 mrbelk

That's a new class in 1.1.3. Just to confirm, have you called the Init() method in your Android Main Activity? https://github.com/XamFormsExtended/Xfx.Controls/blob/master/example/Xfx.Controls.Example.Droid/MainActivity.cs#L14

ChaseFlorell avatar Jan 04 '18 17:01 ChaseFlorell

Yes, but it's the compilation process that fails; not the actual app running. We don't get that far.

mrbelk avatar Jan 04 '18 17:01 mrbelk

did you try a full clean/rebuild in RELEASE? I wonder if there's a dll mismatch after the update?

ChaseFlorell avatar Jan 04 '18 17:01 ChaseFlorell

yes I did.

mrbelk avatar Jan 04 '18 17:01 mrbelk

so if the issue is at compile time, then it's not the Linker. What happens is that the linker strips classes during compile time so that at runtime they're no longer there (ie: linker issues will cause runtime crashes). I'm leaning more to a dll mismatch.

Make sure you've done the following. Clean > Close Visual Studio > delete all obj + bin directories > Open Visual Studio > Rebuild

I'm trying to reproduce, but cannot.

ChaseFlorell avatar Jan 04 '18 17:01 ChaseFlorell

Alternatively, if you can send me a repro, I'll take a look.

ChaseFlorell avatar Jan 04 '18 17:01 ChaseFlorell

give me a bit to completely clean the solution as well as deleting the contents of the "packages" folder in case the dll mismatch is coming from nuget.

mrbelk avatar Jan 04 '18 19:01 mrbelk

does 1.1.3 require xamarin forms 2.5, by any chance?

mrbelk avatar Jan 04 '18 19:01 mrbelk

I've cleaned everything out and still get the linker error. Could it be something with the target android framework version?

mrbelk avatar Jan 04 '18 20:01 mrbelk

all my xamarin.android.support.* packages are v26.1.0.1.

mrbelk avatar Jan 04 '18 20:01 mrbelk

I wonder if it makes a difference what the support packages are? Here's what I'm using.

hmmm... let me see if I can downgrade my support libraries and target framework and see what that does

mrbelk avatar Jan 09 '18 18:01 mrbelk

Getting the same problem... How can I help you to find the issue?

Edit : updated to v.26 but now it's failing on https://github.com/martijn00/XamarinMediaManager/issues/278, I don't get the XFX's error anymore, but I don't know if it's just not displayed because XamarinMediaManager fails first. Disabling the linker for now :/ ...

toverux avatar Jan 25 '18 12:01 toverux

Also have this problem with linking. Our only alternative right now is using a native implementation for android. Why doesn't linkskip work for this plugin?

With newer version of Xamarin there is and issue between system drawing color and xamarin forms color. Only solution is to download source upgrade packages, fix this issue and reference dll locally to your project.
