Try this code:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstance);

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Drive.API)
            .addScope(Drive.SCOPE_FILE)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
}

Then set the connection code for authorization to occur:

@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}

I am following the documentation - Authorizing Android Apps, this documentation also provide give on how to handle ff the user has not previously authorized the application.

Hope this helps.
