Re: [android-developers] How to sign Android app with system signature?

You can't unless you have built the system yourself; if you have built the system yourself, then you have the build system, and can build your app with that and set it to use the desired cert.

Note that this sentence is contradictory: "downloaded and compile Android 2.1 version with signed-google_ion-ota-14721.zip".  The signed-google image is a pre-built image that has been signed with the vendor's own private keys that you have no access to.  That is basically the opposite of downloading and compiling your own image, where you use your own keys (or the default ones in the build system that are for test dev builds).

Can someone describe the whole process for signing a user application
with system signature as I am completely new with signing process.

Thank you in advance.
