I’m writing a testing suite for my other apps that triggers system intents, specifically ACTION_DOCK_EVENT.

I know I need to add android:sharedUserId="android.uid.system" to my android manifest in the manifest tag and I need to install my app in /system/app instead of the normal /data/data.
I have root access so that’s not a problem.

The problem I’m running into is, it appears I also need to sign my app with a system key. Where do I get a system key store, users names, and passwords? I assume I could build my own version of Android and sign it with my own keys, but since I have root access there should be an easier way right?

I have a N1 with CM7 and the emulator I’d be fine with keys for either.

Thanks.

    Turns out the send broadcast intents via adb with commands like:

    am broadcast -a android.intent.action.DOCK_EVENT --ei android.intent.extra.DOCK_STATE 2

    To test ACTION_DOCK_EVENT.
    I couldn’t figure out a way to do it from another app, but adb worked for my needs.
