il2cpp android build error unity 2019.1.6f1

Question

Hi guys,

I have been trying to build a 64 bit version of my app for android with il2cpp but it keeps on failing. I am desperate for help. Please help me out. Thanks a lot. This is the first error:

The key part of this error message is:

 D:\Unity Projects\Trivia Game\Temp\StagingArea\Il2Cpp\il2cppOutput/Assembly-CSharp.cpp:36692: error: undefined reference to 'openPage'

This means you have some function named openPage which is an extern function in C# code. It requires a native implementation. It looks like you don't have a native library for Android which implements this function. So you can either remove the C# code which declares it or provide a native implementation for Android.

this was exactly my issue. I had a function that returned a value on android but on iOS it was calling a native function:

 [DllImport("internal")]
 public static int iOSnativeFunc();

I wrapped this code between preprocessor directives so it would only compile on iOS and not on Android:

 #if UNITY_IOS
     [DllImport ("__Internal")] //or something, don't remember exactly
     public static int iOSnativeFunc();
 #endif

sorry I might not have the keywords right, I'm typing from my phone.
