I have installed an App in my cellphone and my ask is if i can use any program for make a xap of that App for install it from the SDK

If you're asking if you could install an non-Windows Phone app, then no is the short answer.

[alejoseed]

No, i ask if i can use and App installed on my phone and make it a xap for install it from the SDK

[pahutakz]

you mean you want to deploy your xap file into your device instead of emulator?

[alejoseed]

I want to extract xaps of my cellphone apps

[xnk06]

you want to backup your installed apps into xap files. is that right?
i think you can't do that, but let's just hear the answers from expert users

[xandros9]

Well, there is a "download and install manually" option in an apps store webpage.
That would download an XAP for local installation.
However you still need access to the store and it still needs to be listed.

[alejoseed]

Yes i try that of the download and install manually but i can't deploy those with anything, sdk , etc

[SSgt Bruskowiz]

No. Backing up apps from your phone with the intention to reinstall later is normally not possible. This is intentionally opt-out because people can use it for piracy reasons.
Downloading the xap file from the store doesn't help either.
All those apps are signed...you must remove that part from the app in order to reinstall it outside the store and that's not allowed...same story piracy.

Yea, very questionable topic....but, yea, it's been done before (Note: rooted WP8 devices, AKA Samsung only)...

I understand what the OP wants to do, he wants to install a app to his phone, then create a XAP from the app that is installed on his phone.

This only promotes piracy of applications and should be closed.

[alejoseed]

My intentions are clean, I hate the piracy and all what I wanna knew was what I ask but as you people respond to my question now I am clean so if the admin think that it promotes the piracy I'll fully agree with your decision

[SSgt Bruskowiz]

No one accusing you of anything. You just asked a question. I am not against piracy at least til a certain level. When you bought a app and the developer pulled it from the store i don't see it as piracy, you just use a improper method to reclaim what you already bought.
