Android documentation


Doorbell requires a min SDK version of 16.

You can install Doorbell via Maven Central.

Include the following in your dependencies:

implementation 'io.doorbell:android-sdk:0.4.7@aar'

Note The SDK uses AndroidX components, so your app will have to be compatible with it.

In the activity where you want to use Doorbell, you'll need to import the library using:



There are many methods that you can call on the Doorbell object:

  • setEmail(String email)
  • addProperty(String key, Object value)
  • captureScreenshot()
  • enableNPSRatings()
  • disableNPSRatings()
  • resetProperties()
  • setTags(ArrayList<String> tags)
  • getDialogBuilder()
  • show()

And also you can access all the views in the AlertDialog with the following methods:

  • getMessageField()
  • getEmailField()
  • getNPSLabel()
  • getNPSField()
  • getNPSScoreLabelLow()
  • getNPSScoreLabelHigh()
  • getPoweredByField()


    // In your activity
    int appId = YOUR-ID-GOES-HERE;
    String apiKey = "KEY";

    Doorbell doorbellDialog = new Doorbell(this, appId, apiKey); // Create the Doorbell object

    doorbellDialog.setEmail(""); // Prepopulate the email address field
    doorbellDialog.setName("Philip Manavopoulos"); // Set the name of the user (if known)
    doorbellDialog.addProperty("loggedIn", true); // Optionally add some properties
    doorbellDialog.addProperty("username", 'manavo');
    doorbellDialog.addProperty("loginCount", 123);
    doorbellDialog.getEmailField().setVisibility(View.GONE); // Hide the email field, since we've filled it in already
    doorbellDialog.setTags(new ArrayList<String>(Arrays.asList("tag1", "tag2")));

    doorbellDialog.getDialogBuilder().setTitle("Dialog title");

    // Capture and send a screenshot of the current activity,
    // (only available on certain paid plans)

    // Enable NPS ratings (only available on certain paid plans)

    // Callback for when a message is successfully sent
    doorbellDialog.setOnFeedbackSentCallback(new {
        public void handle(String message) {
            // Show the message in a different way, or use your own message!
            Toast.makeText(context, message, Toast.LENGTH_LONG).show();

    // Callback for when the dialog is shown
    doorbellDialog.setOnShowCallback(new {
        public void handle() {
            Toast.makeText(context, "Dialog shown", Toast.LENGTH_LONG).show();

    // Callback for when there is an error, if you want to handle it separately instead of showing a Toast
    doorbellDialog.setErrorCallback(new RestErrorCallback() {
        public void error(String errorMessage) {
            // Handle message
            Toast.makeText(context, errorMessage, Toast.LENGTH_LONG).show();

Material Components Example

    // If using Material Components, you can initialize Doorbell like this:
    Doorbell doorbellDialog = new Doorbell(this, appId, apiKey, new MaterialAlertDialogBuilder(this));

Note Valid as of SDK version 0.4.0


As shown above in the example, the Android SDK can capture a screenshot of the current activity, and attach it to the message being submitted.

To make the most of this, please ensure that a button to send your a message is included on all activities on which a screenshot would be important.

The ability to capture a screenshot and show Doorbell when the user shakes their device will be released soon.

Shake gesture

You can configure Doorbell to be shown when the device is shaken.

You can configure this in each activity.



    public class MyActivity extends Activity {
        int appId = YOUR-ID-GOES-HERE;
        String apiKey = "KEY";

        protected Doorbell doorbellDialog;

        protected void onCreate(Bundle savedInstanceState) {

            this.doorbellDialog = new Doorbell(this, appId, apiKey);

        protected void onResume() {

        protected void onPause() {
