Got it to work. For reference to anyone else, in addition to signing
with the platform key, the ACTION_REBOOT intent has to have a few
extras defined. Without any extras, it looks like the Watchdog thread
will basically ignore it.
This code would do an immediate reboot:
Intent i = new Intent(Intent.ACTION_REBOOT);
i.putExtra("nowait", 1);
i.putExtra("interval", 1);
i.putExtra("window", 0);
sendBroadcast(i);
Details in frameworks/base/services/java/com/android/server/
Watchdog.java in the Android source.
Note that this is not in the API docs so probably subject to change :)
