For the first time in a million years, Google Voice got an actual update. While the changelog is, as usual, of no help whatsoever ("Improved the reliability of SMS delivery"), a teardown teases out an eyebrow-raising tidbit: Google Voice’s configuration settings can now be read by other apps.
The GV update comes packing a new service for handing out this info, called “GoogleVoiceConfiguration,” and a new permission, "com.google.android.apps.googlevoice.permission.FETCH_CONFIGURATION."
There’s an explanation of the permission in the strings file:
<string name="google_voice_fetch_configuration_permission_label">Read Google Voice configuration</string>
<string name="google_voice_fetch_configuration_permission_description">Allows applications to read the configuration of Google Voice, including your Google Voice phone number.</string>
That's about it for the cold, hard facts.
