Google Drive SDK Activity Not Found Exception

Question

I am trying to implement Stephen Wylie's Google Drive example (here). Here is my code:

Can anyone help out?

Answer 1

We've been doing some experimenting, and our current theory is that the new Google OAuth Library depends on having the latest version of Google Play.

We found that if your device still has the Android Marketplace, or an older Google Play we couldn't get OAuth to work.

So you might try opening the Android Marketplace or Google Play App to kick off an upgrade.

Open the Android Marketplace, Accept the Upgrade to Google Play.
Close the Marketplace, and open the Google Play App. Accept the Terms of Service for Google Play. Wait a few seconds, sacrifice a chicken, and then you should be able to run Google OAuth.

EDIT: Looks like Google Provides some guidance on what your app should do if your users are missing the correct Google Play version. See: https://developer.android.com/google/play-services/setup.html#ensure

Answer 2

Google Drive API seems (acording to the Google people) to only works on a real Device, in the Emulator it will crash with this error.

So my Advice, try on a real device.
