[android-developers] Determine Sender of Broadcast

Hello,

Is there any way to discover which app package sent a broadcast? If
the sender includes their package name as an extra in the Intent, can
you verify the sender is who they say they are?

I came across this post (http://www.unwesen.de/2011/04/10/android-
intent-sender-verification/) which describes implementing a custom
handshake protocol using a Service naming convention to verify the
sender if they supply their package name. I can also imagine doing
something similar using broadcasts by using Intent.setPackage() to
limit the scope of the broadcast.

Does anyone know of an Android API based way to verify the sender
package?

Thanks,
Alan
