Integrating Dropbox Accounts

This topic explains how to allow your users to sign up for and log in to your mobile app with their Dropbox account. Just add a few parameters in the developer portal and a few lines of code in your mobile app and you will be social-ready!

Configuring Dropbox integration

Creating a Dropbox application

To get started, you first need to create a Dropbox application and get your Dropbox app key and app secret. For the detailed instructions, see the Dropbox official documentation.

You will need to fill in the following information.

  • What type of app do you want to create? (Please select "Dropbox API app")
  • What type of data does your app need to store on Dropbox? (Please select "Datastores only")
  • Provide an app name, and you're on your way. (Please put your application name) When your Dropbox application is created, you will get a Dropbox app key and app secret.

Next, please configure your application. In "Redirect URIs", please specify the value that corresponds to the server location you've selected (please put your AppID in ${your-app-id}).

  • "Settings" > "OAuth2" > "Redirect URIs"
    • United States: https://${your-app-id}${your-app-id}/integration/webauth/callback
    • Japan: https://${your-app-id}${your-app-id}/integration/webauth/callback
    • Singapore: https://${your-app-id}${your-app-id}/integration/webauth/callback
    • Europe: https://${your-app-id}${your-app-id}/integration/webauth/callback

Configuring a Kii application

Take the following steps in the developer portal to configure your application by setting your Dropbox app key and app secret.

  1. Click on the "Edit" button in your application console in the developer portal.


  3. Click "Dropbox" to open the configuration screen for Dropbox.

  4. Set your Dropbox app key and app secret.

Then, add the following tag under the application tag in your AndroidManifest.xml so as to enable the Activity that the SDK uses for Dropbox authentication.

    android:label="@string/app_name" />

Logging in with a Dropbox account

Here is the sample code for letting a new user log in with their Dropbox account:

Activity activity = this.getActivity();
KiiSocialConnect connect = Kii.socialConnect(SocialNetwork.SOCIALNETWORK_CONNECTOR);

Bundle options = new Bundle();
options.putParcelable(KiiSocialNetworkConnector.PROVIDER, KiiSocialNetworkConnector.Provider.DROPBOX);

// Login.
connect.logIn(activity, options, new KiiSocialCallBack() {
  public void onLoginCompleted(SocialNetwork network, KiiUser user, Exception exception) {
    if (exception != null) {
      // Handle the error.

The basic steps are as follows.

  1. Create an Activity for handling logging in with a Dropbox account.
  2. Create a social network connector instance with the socialConnect() method. Here, we are specifying SocialNetwork.SOCIALNETWORK_CONNECTOR.
  3. Create a bundle and specify the target social network service. In this case, we are specifying Provider.DROPBOX.
  4. Authenticate the user with the logIn() method. If the specified Dropbox account is new to Kii Cloud, the user is registered before the login. The logIn() method is non-blocking and receives the processing result with the callback method.

Note: You also need to add a method to the onActivityResult() method to finish the Dropbox authentication.

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == KiiSocialNetworkConnector.REQUEST_CODE) {

If the login successful, the user is cached inside the SDK as the current user and you can get the user information with the getCurrentUser() method. You can also retrieve the access token and related parameters with the getAccessTokenBundle() method as follows:

KiiSocialConnect connect = Kii.socialConnect(SocialNetwork.SOCIALNETWORK_CONNECTOR);
Bundle b = connect.getAccessTokenBundle();

// The access token.
String accessToken = b.getString("oauth_token");

// User id provided by the social network provider.
String providerUserId = b.getString("provider_user_id");

// If a new Kii user is created with the logIn method.
boolean kiiNewUser = b.getBoolean("kii_new_user");
