Unity game not working after build (MissingMethodException)

Question

The game on Unity works but when I export it to Android it stops working. When I do build and run in the terminal it gives me the following error:

Do you have latest operating system for Android? I check for similar issues and found one for early 2019 so I suspect you may have old version of Android. — jdweng

@jdweng Yes the Android system is updated to the latest version, and the unity version is also updated (2020.1.0f1). The game in question is EndlessRunner, it is an open-source game made by unity. Here is the link if you want to check it out: github.com/Unity-Technologies/EndlessRunnerSampleGame — Stel K9

Android runs on top of the phone/device kernel and kernel may be old. — jdweng

Possible that this is related to Assembly stripping? E.g. you are using something via a dynamic type that isn't known on compile time yet? — derHugo

Its all about code stripping. If you want fast resolution, you can create link.xml file in Assets folder with next content:

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
    <assembly fullname="Unity.Addressables" preserve="all" />
</linker>

If you don't use Addressables, next code:

<linker>
    <assembly fullname="Unity.ResourceManager" preserve="all" />
</linker>

Also you can do more strict code stripping rules. More information about code stripping you can find by this link.

If you are finding that the Localization package is not working in the build please try the following:

Update to the latest Unity patch version
Update to the latest Addressable Assets package in the package manager.
Try disabling code stripping
Clean and Rebuild Addressables. When Building make sure the Editor is set to the target platform in the Build Settings window.
Try running the Localization Analyzers (0.11.0-preview). This can be found in the Addressables window. Link
