Opengl mono for android - android

I'm trying to convert an XNA project to Android. I saw a video saying I need to have "opengl mono for android" as an option when creating project, but I don't.
Can anyone tell me how to download this extension?

Use MonoGame.If you don't you will need to rewrite your game including all the rendering logic in either C# using Xamarin.Android or a complete rewrite in Java.
So your best choice would be Monogame:
monogame.net
EDIT
I just found this on an other site it's called exen, but I still think Monogame is a better one because there are many people using it.

How to open my Android native application with Xamarin.forms?

I've been developing an Android application with Android Studio and now I need to be able to open it with Xamarin.forms in Visual Studio (it's a task that my teacher gave me, and it's because a classmate has been creating the iOS version and now we will combine them into one project).
I have to say that I'm pretty much a noob and been looking a few tutorials that talk about Dependency Service and other stuff, but don't seem to quite cover what I'm looking for (or, at least, not clearly enough).
If you have a precise video that explains simply how to do this, I would be grateful if you share it with me.
I thank you for your time and wish you a great day :)
It is impossible at even now in current version of Visual Srudio .
Every file in Xamain is different with Native Android . The Java code can not be directly copyed to use in Xamarin , you should translate them to C#.
Having a look at this document: Porting Java to C# for Xamarin.Android .
There are two ways to port Java code to C#. The first way is to port the code manually. ..The second porting methodology is to try and automate the process by using a code converter...There is often a non-trivial amount of work involved with bootstrapping an automated code conversion tool, and this may prove to be a barrier to use. In many cases, it may be simpler and easier to port Java to C# by hand.

Android studio c++ ndk support

One of my friends suggested to use c++ support in Android studio in order to hide passwords. I have found tons of tutorials how to get started with ndk in android. But they are all outdated(2015) and everytime I try to use c++ in any way, Android studio crashes. Is there any way to do it in a simpler way now?
P.S./ I want to get rid of experimental plugin that every one uses.
Little off the question, storing passwords in the native layer does not ensure complete safety. A good hacker can get that as well. It is just that you add another additional layer so one has to dig deeper

TarsosDSP with Android - no relevant source code

I follow up on this article: TarsosDSP with Android
I am trying to implement an android application that reads mp3 files and processes them using WEKA.
The TarsosDSP seems to be a good step in the right direction, especially since the Berkley guys seems to have implemented a fork with android.
When I tried downloading their source code here: TarsosDSPAndroid Source Code
I still found a lot of references to javax.sound, which is kind of counter-productive.
So is something mixed up with their uploaded source code or am I looking in the wrong place?
Perhaps some background to what I am trying to accomplish overall:
I am writing an Android App that will read the entire mp3 library, and using WEKA and pre-loaded test-groups will classify each song to appropriate genre.
The part of reading the mp3 library is all done and so is the classification using WEKA, now I am stuck in joining them up - What seemed to be working fine using jAudio in a java project doesn't work for android because of the dependency in javax.sound, so I am trying to bypass that using a different library that works for android.
Thanks in advance!
-Alex
Version 2.0 of TarsosDSP supports Android out of the box. There are no more dependencies on javax.sound.*. This makes it a lot more easy to work with on Android. There is even an TarsosDSP Android jar file that can be included in your project directly.

Simple alternative for gstreamer on android

For training and fun I want to build an android app, that is able to stream audio from one device to another. It will be a simple baby-phone app.
I've tried using gstreamer, but have some trouble including the binaries and building the eclipse project. However, now I am looking for alternatives. Does any one know a simple one? Or is there even some android api stuff I can use? Please note: the difficult thing is not receive a stream, but provide one...
Thanks a lot in advance!

MonoDroid VS Java in android development?

I know C# rather well and just love Visual Studio as IDE. :) Yet now I want to start developing for android...
I found out about MonoDroid and wanted to ask if it has any downsides to it that would make Java more preferable, or should I uninstall Eclipse and dive straight into MonoDroid?
If I understand right, MonoDroid deploys/compiles native android applications and does not need any additional .net-like framework or anything?
Are there any significant limitations to what I can do with MonoDroid? For example, having the app run in the background or using some external .net libraries for image editing, etc. ?
I've been worrying about the same thing - productivity in C# instead of playing with an unfamiliar language, vs developing how the OS developers intended it to be.
Its easy to list pros vs cons -
pros (of monodroid, for C# developers)
familiar dev environment, can develop using Visual Studio
C# instead of Java
Reusable code assets - you can use a lot of code in your iphone project or Windows phone 7 project using monotouch and the WP7 SDK.
cons -
debugging could be difficult, due to lack of api documentation from Google. Will have to depend solely on monodroid documentation.
there could be a lag when it comes to latest cutting edge features - safe to assume that the monodroid team will require some time to wrap around the latest android features every time there is a new OS release
availability of libraries - I am not sure how you can use the open source libraries that would have evolved around the android platform, that could cut down on development time
Much of the documentation available is in Java: so if you run into difficulties with phone behavior when using MonoDroid you won't really find that much help or debugging information so you may want to stick with Eclipse.
There's a lot more than just a set of wrappers running under davlick, truth to be told, there is much more of a horizontal relationship between MonoDroid and Android;
When did using the same language as the OS developers become a big issue? There's lots of C++ programmers wondering how to use BSD or SVR5 and many C programmers who want to know what the heck to do on Windows++...
If you will write in c# anyway you will be have to wrap it into a Java code, so what's the point ? Also you may head with a very difficult issues while trying to understand the APIs who written for Java programming...
Here are some points that you can mull over:
Android applications are predominately written with Java. The Android SDK itself is natively written in Java.
Working in Mono may not provide all the functionality available in the Java SDK.
If you are a C# Developer you wont be able to find, in Java, some of the (cool) features available in C# (like Property Delegates etc).
Code written in .NET can be re-used for other environments - this may save a lot time that would have been spent learning a new language/environment (like Objective C), and coding in it.
.NET extends the Android development stack with it's existing libraries and API's.
I think both are good for certain reason. It will be very hard to say which one is preferable for Android development - in the end that is up to you too decide.
Also note that any release build using monodroid adds an additional 4mb to the apk filesize and increases app startup time with a few seconds.
For simple apps this can mean a 500-800% increase in filesize - whic is pretty bad in my book.
