I am trying to use unreal’s built-in “AndroidAdvertising” module in c++.  
Below is the AndroidAdvertising module’s location in 4.27

Firstly, I added “AndroidAdvertising” to the build.cs

 ![PublicDependencyModulesProject750](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/9/d/d9dad3bbad5bdfdcf9aa3b0e1eff68bfcf0db8d7.png)

target.cs

After this I tried to build the solution(without adding any extra code) which gave a linking error:

> LINK : fatal error LNK1181: cannot open input file ‘E:\Unreal Engine\UE\_4.27\Engine\Intermediate\Build\Win64\UE4Editor\Development\AndroidAdvertising\UE4Editor-AndroidAdvertising.lib’

Project Structure:

I have a custom “Android” module in which I am trying to access unreal’s “AndroidAdvertising” module.

Any help or suggestion will be appreciated.

Could it be that the `Type` is `Editor` when it is a `Runtime` module?

Set the `module` `type` to `Runtime` :  
 ![AndroidAdvertisingSettoRuntimeinP750uproject](https://d3kjluh73b9h9o.cloudfront.net/original/4X/6/9/b/69bc2e3550ada994f697584286bd513a16464bd5.png)

then → “`Generate Visual Studio project files`” → “`Build`”

Still Got the same Error: `LINK : fatal error LNK1181: cannot open input file ...\AndroidAdvertising\UE4Editor-AndroidAdvertising.lib'`
