I want to add VoIP functionality to my application, without developing required VoIP/SIP libraries myself. Is it possible to "link" Skype to my application? Maybe via a button, which starts Skype?
Otherwise, are there any open source code projects for Android VoIP/SIP available (such as SipDroid?)
There is a VOIP open source project and it uses google voice as well, and there may be others, if you want to launch skype you will need to use an intent, maybe answered here as well Skype Intent and you may be able to google android skype and intent if none of that works

I want to ask about native app development. My client asking me for making application where the app can easily remove another app on the device (I mean Uninstall another app programmatically) with a spesific shortcut (for example maybe by shake device etc). It's possible to make this app on newest android OS?
if possible, can you give me a reference? or example code to remove another app? thank you!
I have implemented a MusicPlayerService by following the official guide from the Android Developers site. At multiple places, I have found the information that this should be enough to make my app ready for Android Auto.
But if I open that (just the phone interface because I don't have a compatible car at the moment), the list of music providers just contains Google Music and the already installed VLC media player. To verify I also downloaded, compiled and installed the Universal Music Player example, which isn't showing up either.
Do I have to enable something or even upload the app to Google Play first?
EDIT: I now tested it with the Desktop Head Unit and it works. Afterwards the service is also visible on the phone interface. But this is not the expected behavior, right?
Only apps installed through Google Play will be shown in Android Auto. If you want to test your app with the phone interface, you'll need to enable developer mode and the 'unknown sources' option in the developer settings.

I've gotten an android service written as a stand-alone APK and I'm trying to include this in the SDK so it automatically installs the service through some publicly exposed function from the SDK.
Is there a way to achieve this?
For instance, the SDK is monitor.jar which has helper functions.
The service is GetCurrentMonitor.apk which runs a background service that returns the value of some stock currently monitoring.
Now, I want to release the SDK so that when it's included in some 3rd party app, it automagically installs the background service for GetCurrentMonitor project...
Any help is greatly appreciated.
Thank you,
Your question is very confusing. Here is my interpretation of what you are asking:
I have an Android application that has a service. I have a separate SDK (JAR or Android library project). I want users of the SDK to be able to call a function and have the APK containing the service be downloaded and installed.
This is possible, sorta.
You can have code in your JAR that either:
call startActivity() on an ACTION_VIEW Intent for the market: Uri pointing to your app on Google Play, or
downloads an APK from some server of yours to external storage, then calls startActivity() on an ACTION_VIEW Intent pointing to that downloaded APK, to kick off an install
In either case, the user will need to get involved in the installation process -- you cannot install apps silently. And, in the latter case, you will be responsible for handling your own updates over time.
This also will tend to confuse the user, as they may not realize why your app is floating around their device, so you will need to be able to handle the case where they uninstall it.
Also, it is possible that on Android 3.1+, the user will need to launch an activity of yours before your service will be usable. With luck, that is not required, though I cannot rule it out at this time.
And, of course, if I did not correctly understand your question, please consider editing the question to clarify what it is you are trying to accomplish.
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.
I am implementing a system for touchscreens in java that needs to be able to call up skype, how can I go from a fullscreen java app to having skype open, then closing the skype window and getting back to the fullscreen app. Is this even possible?
When Skype is installed, you can use the callto:// or skype:// protocol to start skype.
The syntax is
skype:<username|phonenumber>[?[add|call|chat|sendfile|userinfo]]
http://en.wikipedia.org/wiki/URI_scheme
If it's a touchscreen system then why do you want to show the standard Skype UI? It's not a touch-compatible interface. Have you considered using the Skype API to interact with the service instead?
There's a desktop automation library already available and a service SDK in beta.

I'm pretty sure you will have to implement a native library which will have to search through all windows in the system, find the Skype one and bring it to front. So it is possible, but with the help of native library -- which then you can still use in Java through JNI.
