Use Dll Files in Android Application

Can I use dll files in android application?

You cannot use DLLs with a native Android application. Android applications run on the JVM on a linux kernel, but DLLs are a Microsoft creation.

If this DLL is a critical component of your application and you cannot re-implement it in Java, then you may want to consider Xamarin, which allows you to write applications in C#. Be aware that if you go this route there are a number of significant tradeoffs. You should ensure you fully understand these tradeoffs before making this decision.

Use dll files in android Application

Android runs on a Linux system - DLL files are usually bytecode compiled for Windows.

using dll library in android application

Dynamic-link library (also written unhyphenated), or DLL, is Microsoft's implementation of the shared library concept in the Microsoft Windows

Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google.

So no, you cant. Teoretically in some kind of VM, still - no.

C# .dll library in Android app

1. The DLL generated is compiled against the Mono for Android profile, which is based on Moonlight (Mono's implementation of Silverlight). At runtime, .NET code is run directly against the Mono runtime which runs as part of your application. When .NET code subclasses something from the Java side (e.g. Java.Lang.Object), Mono for Android generates callable wrappers to handle communication between runtimes.
2. Technically you can use a normal .NET DLL in your Mono for Android application, but I wouldn't recommend it. The profile exposed by Mono for Android is much smaller than that of the full .NET framework (and isn't even completely equivalent to that of Silverlight), so if your DLL references a method that isn't found in Mono for Android, your application will crash. Instead, I would recommend creating a separate class library for your application, and share source files across projects using file linking. My blog post here contains an example of how to do that.

Using dll-Library in Unity3D for Android Build

I'm sure it's possible because in my current project I use multiple external dll.

my link.xml file is like this:

<linker>
    <assembly fullname="MegaApiClient"> // the name of the assembly
        <type fullname="CG.Web.MegaApiClient.*" preserve="all"/> // excludes all namespaces and classes recursively under MyNamespace
    </assembly>
</linker>

preserve="all" was because with the new il2cpp compiler can automatically strip some "not necessary code" (in my case it was a getter/setter and it was necessary).

No DLLs inside of apk file?

Many of Unity projects are built using IL2CPP, what it does is convert the code to c++.

In this case you will find libil2cpp.so in your ./lib folder inside the apk.

You can try to dump the Dlls from this file using some tools like Il2CppDumper
