I am not able to install my Android app on my Samsung galaxy pop

I am facing a strange problem. I created an apk of my application with unsigned key and tried to install it on my samsung galaxy pop, but i am not able to install it on my samsung galaxy pop. I enabled the option for installation of non market place app but i am getting un开发者_StackOverflow中文版able to install message.

However when i am connecting phone with USB and clicking on run it is getting installed in the device.

is there anything wrong in my approach??

this is my sample apk file which i am trying to install http://www.mediafire.com/?aotxfupx7h7t568

Thanks

You must sign it

From Signing Your Applications

*The Android system requires that all installed applications be digitally signed with a certificate whose private key is held by the application's developer. The Android system uses the certificate as a means of identifying the author of an application and establishing trust relationships between applications. The certificate is not used to control which applications the user can install. The certificate does not need to be signed by a certificate authority: it is perfectly allowable, and typical, for Android applications to use self-signed certificates.

All applications must be signed. The system will not install an application that is not signed.

It couldn't be any clearer

If you are doing this from Eclipse and running the app on handset, I think android treats it differently, since you probably had USB debugging enabled and the handset is fooled into thinking it is debugging.

When you tried installing the app, because it is not signed the handset may be rejecting it.

You should be fine running and debugging like this, but when you create the final apk you will need it signed.
