final String token = GoogleAuthUtil.getToken(context, "xxxx@gmail.com", scope);

Intent res = new Intent();
res.addCategory("account:xxxx@gmail.com");
res.addCategory("scope:oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
res.putExtra("service", "oauth2:https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile");
Bundle extra= new Bundle();
extra.putString("androidPackageName","com.your.package");
res.putExtra("callerExtras",extra);
res.putExtra("androidPackageName","com.your.package");
res.putExtra("authAccount","xxxx@gmail.com");

String mPackage = "com.google.android.gms";
String mClass = "com.google.android.gms.auth.TokenActivity";
res.setComponent(new ComponentName(mPackage,mClass));
startActivityForResult(res,100);

Now, when you revoke the access here https://accounts.google.com/IssuedAuthSubTokens the application shows you the window for permission again in the device.
