Question

When creating an android project in unity there is always these 3 errors that doesn't make it compile without even adding anything.

1. C:\ProgramFiles\Unity\Hub\Editor\2019.2.0f1\Editor\Data\Resources\PackageManager\BuiltInPackages\com.unity.ugui\Runtime\EventSystem\InputModules\BaseInput.cs(19,24): error CS0246: The type or namespace name 'IMECompositionMode' could not be found (are you missing a using directive or an assembly reference?)

2.

Answer 1

This seems to be the same error as in this post: https://forum.unity.com/threads/i-have-a-problem-getting-start-in-webgl.736436/

This was for a WebGL build but if you follow the link in the sixth post (changing the version number) there's a download for Android as well.

In my case I has installed WebGL Target Support for Unity 2019.1.1 (which I used for an older project), but my current project was on 2019.2.1. So go to https://unity3d.com/unity/whats-new/2019.2.1 (replace the last part of the url with whichever Unity version you're using) and scroll down to WebGL Target Support and download+install it (choose the correct Unity path in installation). That should fix the problem.

Answer 2

Did you install the android build support module on your current unity version ? I had the same errors once and I realised this was the reason...

Answer 3

It's possible that the Package Manager from Unity (by some reason) is missing those files, and therefore cannot find them.

You could try:

• Reset the packages to default values (go to Help -> Reset Package to Defaults)

• Another thing that you could check, but only if you are using Assembly Definitions (.asmdef files), in this case, you should check if the dependencies are set correctly.
