Tutorial: Signing in and out

The Webcom Authentication Service provides a lot of authentication methods to sign users in to your applications.
By default, only the Webcom email-based login is enabled when creating a new Webcom application. In order to use other authentication methods, they must be explicitly enabled and setup in the "authentication" tab of the Webcom developer console.

Automatic reconnection: when the network connection is lost and returns, the Webcom SDK will automatically re-sign the currently authenticated user in to your application with the Webcom.

Sign out

The sign out procedure is common to all authentication methods, it basically consists in "forgetting" the authentication state (and the associated Webcom token) locally on the device. This means that there is no interaction with the Webcom back end and no token is actually revoked. Therefore, the forgotten token is still valid and may be used further on any device.

The following example shows how to use the sign out procedure (replace “<your-app>” with your actual application identifier):

// Create a reference to a Webcom application
var ref = new Webcom("<your-app>");
// Sign out
ref.logout(function (error) {
   if (error) {
     console.log("The sign out failed: " + error.message);
   } else {
     console.log("Signed out successfully!");
   }
});

try{
    // Create a reference to a Webcom application
    final Webcom ref = new Webcom(new WebcomApp("<your-app>"));
    ref.logout(new OnComplete(){
       @Override
       public void onComplete() {
            Log.v(TAG,"sign out complete ");
       }
       @Override
       public void onError(WebcomError error){
            Log.v(TAG,"onError : " + error.getMessage());
       }       
    });
} catch (Exception e) {
    Log.e(TAG, e.getMessage(), e);
}
