If you are planning on testing your app before you sign it. As far as I know, non-signed apps on an android can be tested by adding a debug - notification in the manifest file by adding android:debuggable="true" to the element.

Hope this Helps you!

As the docs say, you must sign your APK for it to be installed. Just go ahead and sign it, it doesn't take anything special, you don't have to have a Market account or anything like that. All the directions you need should be in the link I included.

Unsigned applications can be installed on device only in condition that the device is connected to the development machine or else not.

TO install the APK explicitly, it has to be signed.
