I am trying to access the google drive through android app. I have turned on the Drive API and Drive SDK in Google Developer Console and generated a OAuth Client id.
Inserted the Client key in AndroidManifest.xml as
<meta-data
android:name="com.google.android.apps.drive.APP_ID"
android:value=id="***CLIENT_KEY***" />
And a permission as
<uses-permission android:name="android.permission.GET_ACCOUNTS"/>
<uses-permission android:name="android.permission.INTERNET"/>
This is the code which I am trying to run (Originally from here)

This is the error I am getting
02-19 18:58:18.204 27221-27221/com.gajendraprofile.drive I/android-drive-quickstart﹕ GoogleApiClient connection failed: ConnectionResult{statusCode=INTERNAL_ERROR, resolution=null}

Am I making any errors above? Are there any better simple example to access Google Drive from Android?
