The binary distribution of the Skype Runtime comes with a "SkypeKit" - a runtime that applications can connect and communicate with in order to leverage Skype functionalities.
Their developer forums state that there are no official Runtime available as of now but the distributions come with a linux-armv7-eabi compilation and java wrapper classes that help in communicating with this Runtime.
I am trying to understand :
1. how to get this Runtime up and running on the Android emulator system so that I can test the APIs out?
2. How do I package the compilation in my existing Android application?
Any pointers or help in this direction are welcome.
Thanks.

So this is probably a silly question.
I have this rather complicated app that would be a heck of a lot of work to convert to Java.
It runs in the command line and works fine in Linux.
Trying to run it fails, but x86 bytecode probably isn't very ARM friendly.
Is there a specific way I need to compile the application?
Is it even possible to run it from a console emulator?
Thanks.
Try Android NDK
I am also new to Android Dev ( 15+ years Linux, 10+ years Java, etc.)
I am not an expert but for your purposes you need the "Android NDK" in addition to the "Android SDK" that most developers utilize.
"The Android NDK is a toolset that lets you embed components that make use of native code in your Android applications.
Android applications run in the Dalvik virtual machine. The NDK allows you to implement parts of your applications using native-code languages such as C and C++. "
Basically the tools are needed to cross compile C++ source code for the target ARM environment.
I am prevented from posting the download URL for some bizarre reason, but it is listed under "Native Development Tools" on the left side of the web page for the standard "Android SDK" download.
Yeah that's because you are new. It's a system to prevent spammers from posting URLs.
When you have a couple of posts the restriction will disappear
Anyway; found it, seems to be what I'm looking for.
I'll check it out in the morning.
Big thanks
Dmitry Moskalchukhas written a patch for the ndk to better support c++ see crytax dot net there are posts on google groups android-ndk talking about it
Thxs for the info. I was aware that the NDK did not include all of the libs that desktop Linux/UNIX developers expect. The suggested patched version adds the STL libs back in.
Sent from my PC36100 using XDA App
There are A LOT of libraries missing
I guess I'll just keep it a hosted app.
Thanks for all the input
Hi,
hello everybody,
there's a way to a android device run a java applet in a web browser or by other ways?
tks.
There are a few offline converters that help run selective JVM content on DVM ( android's VM called Dalvik).
But there isn't any end user friendly/on-the-fly one to run java applets on android browser.
Unless implemented and ported native_ly, it would end up being a extra shim on top of DVM, slowing down any app/applet that runs on top of it. It is very unlikely that google promotes this. Competition has pushed them to rush for adobe flash support but that might be the limit.
On the other hand, people have managed to run DVM on other platforms. It has indeed been running from day zero on development emulator on PCs and MACs.
Need someone who can convert GENUINE java to ANDROID Java ... (Java->Dalvik VM)
i have just visited HUMNUT and I am trying to use humnut on android zenithink 180 which is the c71 tablet
HumNut Company Info
We are Humnut. A Dublin based company that started as an idea and with only £250 in 2008 the company was established. Our goal back then was to create a truly free way of making telephone calls to landlines. That was our aim then, and it is still our aim today.
The difference being, we now have the technology up and running.
So how we do it is simple.
We have sourced and are using some of the latest in technologies to run our service and we aim to give our users the best quality we possibly can. Our technology that we use for making the telephone calls is constantly under development and we invest heavily in making it user friendly.
WHAT I WANT FROM HERE IS THAT SOMEONE WHO IS ABLE TO DO THE FOLLOWING
Android = Java | Java.net
weblogs.java.net/blog/opinali/archive/2010/08/17/android-java
open the Browser, press Menu and touch More > Settings>
Tap and put a check mark on this two options: "Enable JavaScript" and "Enable plug-ins"
If a website developer converts their Java .class files to .dex files needed by the Android platform, then that might work.
the Android platform is NOT Java. It is
an entirely new platform which, at best, has a compatibility layer for
Java code.
Android uses the Dalvik VM, which is a register-based VM whereas JVM
is stack-based. Neither the specification nor the source code for
Dalvik are available, but it is clear that the bytecodes are quite
different from Java bytecodes. There is a translation tool from JVM
bytecode (.class files) to Dalvik bytecode (.dex files) but it is a
build-time tool only. JVM bytecodes are never loaded onto an Android
device.
The reason for the custom VM is that Dalvik is optimized to allow
> multiple instances of the VM to run simultaneously even in little
> memory. Each Android application runs in a separate Linux process.
please people keep sending HUMNUT requests to enable/convert website to android java... through humnuts contact form
I am a programmer who has programmed in x86 Assembler, Visual C++ under Windows and DOS.
I need to be able to do own applications for Android KitKat 4.4.4
I need any help and information such as manuals, books, lists of commands, lists of functions, C compiler or, best, Assembler compilers for a given processor, etcetera.
I would like to code in Assembler. I guess I need an Assembler for a given processor and cell phone. In case not possible, I need a C compiler for Android 4.4.4 KitKat. I need the basic rules on how to code for this OS as well as the OS calls which I can use, as well as a description of function libraries which may come with the C compiler.
I prefer pure C than C++ or Java.
I have briefly searched the Internet with various key words and I have not been able to find anything relevant.
Please, does anyone have any information where I can get anything helpful.
I am totally new to this OS and I do not even know the shell commands. I do not have much information of the shell, although I have found a basic list on this forum and I use ls and ? and go by the name as a dumb fool.
Please, advise.
While Android is in Java, it also allows you to run C/C++ native code.
Search "Android NDK" and you will find the relevant documentation.

Thanks. I have tried NDK. I am not sure whether I have installed this correctly but I would keep this.
Because NDK is hardware specific and I am not sure whether and how much Moto E XT1023 and others are supported, I have installed Android Studio 1.2 ad started with XML and Java. I have done similar things with HTML and Java for web sites. I would use XML as much as I can and Java only to get and set some variables, then I would use C for programming and then I would set Java variables and methods. I am not very happy with Java but there is not any other way for now. Hopefully, in the future, they would make XML a real language with all the resources available, functions and methods.
At least Java has a very C-like syntax, so in general it shouldn't be that difficult. In some sense it would even be easier (no memory management).

Yes. You are right. I would prefer, however, a pure ANSI C. This can be done either as an interpreter to be hardware independent or as a compiler upon launch, the system would have a compiler, the user would download only the ASCI text. Upon launch, the compiler would be called first to compile and then the application can be launched. Then, the user can either keep the .exe or keep just the ASCI text, in which case, new compilation has to be done with every launch. A compilation would normally take one or a few seconds only for normal applications.
I recommend using version without demo apps, its smaller. But if you want to try demo apps to test if is JRE working, use version with demo apps.
This app provides a complete Java Runtime Environment (JRE) for Android devices. This JRE include a Java Virtual Machine (JVM) and Java SE 7 class library APIs. This enables running standard Java SE 7 desktop applications on Android devices. This includes Java applications that use Swing and/or AWT graphical user interfaces.
You need to be logged in google account to run this app.
The JRE is capable of running any "pure Java" applications. If the Java application includes/requires application JNI libraries then these native libraries will need to be rebuilt (compiled/linked) with the Android Native Development Kit (NDK).
Using this App to successfully run a specific Java application, will require some basic knowledge of using a JRE. For example you will need to copy the application JAR files to the device's file system and then configure a command line to launch the Java Virtual Machine (JVM).
The following is a list of limitations in the current release.
- Java Applets embedded inside Android web browser are not supported. (There is an Applet viewer included that can be used to run Java Applets standalone)
- JavaFX is not supported.
- Only supported on Android devices with an ARMv7 processor.
The following is a subset of Java applications that currently will NOT run on this app due to missing JNI libraries.
- Minecraft for PC

Java JRE with demo apps
Update: links removed. Moderators not allowed this app, because it is moded JRE4A with crack. I will upload it somewhere else, and here will be Tutorials what write to google, to find it.

While this sounds great, could you give a few more details:
Did you write this yourself?
Why is a Google account required?
How do AWT/Swing work? Don't they usually use native widgets? What does your JRE use instead?

It is JRE4A with removed trial limit, and moded popups to be more user friendly. For example popup with buy, reedem, tral is modded to: Welcome to JRE, OK button have trial button function, other buttons removed. Then dialog this is trial version and will work only one minute... is changed to press ok to start java app. Title changed from jre4a to java, and icon changed to java icon.
Google account is required because of jre4a licencie checking. You dont need to have buyed jre4a, but without account app crashes. It is a bug.
And please removed links from quotes.
Soon i will post guide how to find this files on google
No you will not. Cracked apps and warez are not allowed in anyway on xda. Nor are you allowed to tell people how to find it.
