"Link Assemblies" task failed unexpectedly issue while App build in Release Mode Xamarin Android
Solution 1
I was able to resolve the issue in by changing the Target Android Version
and setting the Java Max Heap Size
in the following manner.
- Right click MyApp.Droid
- Properties > Android Options > Advanced (tab)
- Set 'Java Max Heap Size' to 1024m
Solution 2
Try this configuration for Debug mode
Solution 3
After updated xamarin version i start getting this error. Clean project first then build it again. fixed for me. Rebuild not working.
Solution 4
I got this too after upgrading to Xamarin Forms. You need to make sure your Target Framework is the last version.

A. Sinha almost 8 years@Adel Have u tried increasing the java heap size to a larger value?

Dpedrinha almost 7 yearsYes, that fixes it by disabling the linker. Which is not the expected behavior. so it's not a solution.
