I am looking to write a web page that can load to it and run APK files. Something like a web control that can get an APK file url, load it and let the user interact with the app (No need in the whole android system, just the specified APK).
Is it possible? Is there anything like that in the market? Maybe a standalone open source emulator i can migrate to work on the web?
Short answer: no, but not fully impossible
Long answer: BlueStacks provides a raw and unstable emulation framework that is able to run single APKs without the full Android device emulation, but while it's not designed to run in a webpage, it actually executes as an ActiveX.

I have a JAR (java application), which I want to run on my iPad. Is that possible, How to do this? If possible through Appstore, (I know the process of Appstore and I have Apple Appstore account), please let me know is it possible to upload jar in Appstore and download from there?
No, it's not possible to run jar file into iOS or upload to App store. but Oracle ADF Mobile uses a native container that runs applications on both iOS and Android from a single source base. One part of that native container is a headless/lightweight JVM, but it's definitely not a .jar file

That's impossible. Apple doesn't support Java. Apple uses Objective-C as its main language. If I'm not mistaken, Safari on iOS doesn't support Java too so you can't run applet on iOS too.
Is there an easy way to run Java code on an Android device without actually delivering an apk? I'd like to test out function calls without building an entire project.
For instance, it would be cool to run calls like Camera.open(1) and see what the device responds with. It takes forever to rebuild an entire project and redeploy it for minor changes. The only option I can come up with is having some sort of text field that takes user input, executes commands (Compiler API?) and displays the result. Is there a better way?
There is the Android Scripting Layer
https://code.google.com/p/android-scripting/
There is Dev Apps Direct for looking and loading sample open source libraries.
There is API Demos which is just the official samples from the android sdk that a third party published on Google Play
Is it possible to run java app (jar) in my android application? Because I need to create PDF, the problem is if I generate PDF in android, only can show with small image, if it contains large image in many pages, it will be error. So I think, I can generate PDF in java and then included to android app.
Concernig the mentiones app JBED:
Well honestly, I could not find any credible source for this tools JBED, so I would really be very cautious (e.g. who is the developer?)
In the manifestfile (in Androidmanifest.xml, where every app has to state what rights it needs to run, see How to view AndroidManifest.xml from APK file?) there are many rights mentioned (what could be necessary, as the app wants to run as an emulator), so a java application might want to send an SMS, record audio, take pictures and place calls -- so the emulator would need those rights as well.
But then the app also registers the "android.intent.action.BOOT_COMPLETED" event (i.e. autostart after boot) and this would go against every description of the tool.
Ah yeah and giveaway: The apk has a folder "certs" that has some (root-)certificates. But those are not the real certificates of the authorities, e.g. Versign. If one installs the app and by that those certificates the trust you might have in https-connections is lost because those who made the fake certificates can create own, false certificates that your phone would trust.
I assume (or am pretty sure) this is a spy tool, but I could be wrong. The (rare) testimonials that claim the tool ran perfectly will probably be the same person that posted the tool under a different name.

You can import java Third-party libraries into Android app, follow the steps here.
I am not sure whether it will work,but just try.
If your program is a console program, the answer is yes.
Install Jvdroid from Google play. Click terminal and then write this command: java -jar YourJarFileName.jar
The simplest way would be to some install terminal emulator and then install java and then you can run java apps on standard java. You can even install full Linux distro with x server without rooting the phone, then connect to it from x client and you have Linux desktop on android. Once I've even installed eclipse for java development on it and everything worked. I tested this setup last time in 2014, but I'm pretty sure you can do this nowadays as well. The app with Linux I get from play store as well app for the x client. The app I used back then was "Debian no ROOT" or smthg like this. You need to check what's currently available to make this setup in Google Play store according to your android version and your preferences. Last time I've checked there was a lot of different tools for this kind of task. Lastly I've even successfully installed TF and keras on my android phone using terminal emulator.
You can use JBED. JBED is an .apk Android application which run java games and app on your android Device. JBED is a java android emulator, by using
this application we can install .JAR/.JAD/Java/J2ME/MIDP app on android phones.
You can do it quite easily as there are many ways to run java apps on android. Specific application called Java Emulators can do it quite easily.
These are four most popular java emulators for android viz, JBED, PhoneME, Jblend and NetMite. These are arranged in order of their preference. You can use phoneme for non rooted device, however if your device is rooted try any of the remaining three applications.
I have recently started programming for the Android platform. I have a simple application which I would like to email to someone so that they can execute the application and check how it works.
I am currently using the Emulator in the Android SDK to execute my application but the person who I am emailing it to does not have Android SDK and it would be a mission to send the whole project folder.
Is there any way that I can send just one file such as an .exe or something that would allow the recipient to execute the application to see how it works.
Thanks so much for your help in advance guys
The "exe" for android is called apk. I suggest you to look at this question. You'll need to build the apk and sign it in order to be able to run it.
If you just want to send it to a user for testing purposes, you can enable the setting in the target android device to allow "unknown sources" (I don't know the proper english name, as I don't have an english android here at the moment). You can find this in the app settings.
In your development environment look for the apk file created by eclipse. Then connect your smartphone to the pc and copy the apk over. Start up a file manager and click on the apk and it will install just like any other app.
If you want to deploy it properly, you have to sign it and probably follow the procedures from google. Since I don't have a fully deployable app yet, I can't say what the procedures is for that, but the google site is very helpfull on all aspects about android programming.
Check the "bin" folder in your project path. There you will have a .apk that you can share with your clients.
If they execute it in an Android mobile phone the application will be installed.
How do I build a android executable from my android application? I am building an application where it would send some application data to another device. If the receiver is using my application, there is no problem. But if the receiver is not using my application or not aware of it, the application data means nothing to him, unless the sender informs him about it.
I wish to build a executable, right from my android application, which will run on receiver end. Receiver may not modify it but can run it easily.
Example of such use:
Video recorder or converter application which convert/record video on a custom format and play it. Now the sender wants to send that video to his friend. Unless he have installed such video, he can't access it. However if it is possible for the sender to create some executable to embed that video, which can run on any android device it would be great.
Even if it were possible, it is definitely not practical to compile an application on an Android device. Why not make the compiled application available in the Android market and/or your own URL, and then get the receiver to download and install it?
Like Elevine said, you should send a URL to App in Market instead of sending an app.
If google/Android evev allow sending app directly, Spammers, virus writers will love the "features". It is as bad as ActiveX plugin date of IE5,6.
BTW, I thought about this kind of approach before. One can have all the prebuilt jar, dex files ready and just want to zip them together with new data as resources, signed it with the right key. It is possible to do it in the phone. But you really don't want to do put your signing key in anyone's phone.
It is much better/simpler to just submit the needed data to a server in the cloud have sign the package there.
