Can I build android executable right from my android application

Question

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.

Answer 1

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?

Answer 2

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.
