DLLImport Failed in Android with MAUI

Question

L GG 1

Code：
[DllImport("SDK.dll")]
public static extern int Initialize();

Error：System.DllNotFoundException： 'SDK.dll'

It can be used normally on winform, and an error is reported when switching to MAUI.

Looking for HELP.

Is there any difference in adding DLLs in MAUI?

Based on your error, your SDK.dll cannot be found at the runtime. You can check this document: Dynamic-Link Library Search Order for the DLL search order.

Can I use DLL in MAUI?
MAUI supports it?

What kind of binary is your SDK.dll? Where did it come from?

If the library is Windows specific, then it won't work in Android.

If it's a .Net Standard or cross-platform .Net 6 library then it should work, if you included and referenced correctly in the MAUI project.

It's a supporting SDK for peripherals. I guess it's written in C++. I don't know whether it can cross platforms.

You should confirm with author of SDK, if it supports cross platforms or android platform.
