Android SDK Reference
Complete API reference for the PushEngage Android SDK. For setup and installation, see the Android Quickstart.
The SDK supports Java and Kotlin. Android API 16 (Android 4.1) or higher is required; API 21+ recommended.
Initialization
PushEngage.Builder
Initializes the SDK. Call this once in your Application.onCreate() before using any other SDK feature. The builder registers the application context and your App ID, and build() installs the SDK singleton. The App ID can be obtained from your PushEngage Dashboard under Site Settings → Installation → Android SDK.
This must be called before using any other SDK features. It associates all subsequent operations with your specific PushEngage application.
Syntax
new PushEngage.Builder()
.addContext(Context context)
.setAppId(String appId)
.build()
Parameters
context: Your application Context. Required — if omitted, build() logs an error and returns null without initializing the SDK. The SDK stores the application context internally, so passing an Activity does not leak it.
appId: A String representing the App ID from your PushEngage Dashboard. If null or blank, initialization still completes but the SDK logs an error and skips sync and subscriber requests until a valid App ID is configured.
Usage
- Java
- Kotlin
public class PEApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
PushEngage pushEngage = new PushEngage.Builder()
.addContext(getApplicationContext())
.setAppId("YOUR_APP_ID")
.build();
}
}
class PEApplication : Application() {
override fun onCreate() {
super.onCreate()
val pushEngage = PushEngage.Builder()
.addContext(applicationContext)
.setAppId("YOUR_APP_ID")
.build()
}
}
Calling build() again is safe and refreshes the configuration. If the App ID differs from the previous build, the SDK clears the cached subscriber state and re-registers the device against the new App ID on the next sync. Calling build() with an invalid App ID preserves a previously stored valid one.
Notification Permission
requestNotificationPermission
Requests notification permission from the user. For Android 13 (API 33) and above, this will show the system permission dialog. For older versions, the permission is automatically granted and the callback will be invoked with granted=true.
This method works with both ComponentActivity (Compose) and FragmentActivity. When permission is granted, the SDK automatically calls PushEngage.subscribe() for you, so you don't need to call it manually in the callback.
Syntax
requestNotificationPermission(ComponentActivity activity, PushEngagePermissionCallback callback)
Parameters
activity: The ComponentActivity (works with both Compose and traditional Activities)
callback: The PushEngagePermissionCallback callback to be invoked with the permission result
Usage
- Java
- Kotlin
// Works with ComponentActivity (Compose)
PushEngage.requestNotificationPermission(this, new PushEngagePermissionCallback() {
@Override
public void onPermissionResult(boolean granted, Error error) {
if (granted) {
Log.d("Permission", "User is now subscribed!");
} else {
// Handle permission denied
Log.d("Permission", "Permission denied: " + error.getMessage());
}
}
});
// Works with ComponentActivity (Compose)
PushEngage.requestNotificationPermission(this, object : PushEngagePermissionCallback {
override fun onPermissionResult(granted: Boolean, error: Error?) {
if (granted) {
Log.d("Permission", "User is now subscribed!")
} else {
// Handle permission denied
Log.d("Permission", "Permission denied: ${error?.message}")
}
}
})
getNotificationPermissionStatus
Get the current notification permission status for the application. This method returns the permission status synchronously as a string.
Syntax
getNotificationPermissionStatus()
Returns
A String indicating the current notification permission state:
"granted": The application is authorized to post user notifications"denied": The application is not authorized to post user notifications
Usage
- Java
- Kotlin
String permissionStatus = PushEngage.getNotificationPermissionStatus();
switch (permissionStatus) {
case "granted":
Log.d("Permission", "Notifications are allowed");
break;
case "denied":
Log.d("Permission", "Notifications are denied");
break;
default:
Log.d("Permission", "Unknown permission status");
break;
}
val permissionStatus = PushEngage.getNotificationPermissionStatus()
when (permissionStatus) {
"granted" -> Log.d("Permission", "Notifications are allowed")
"denied" -> Log.d("Permission", "Notifications are denied")
else -> Log.d("Permission", "Unknown permission status")
}
Subscription
subscribe
Subscribe the user to push notifications. This method checks the current permission status and subscription state to determine the appropriate action. If notification permission is not granted, it will automatically request permission first. The callback will invoke onSuccess() when the user successfully subscribes or onFailure() if the subscription fails (including cases where permission is denied by the user).
Syntax
subscribe(ComponentActivity activity, PushEngageResponseCallback callback)
Parameters
activity: The ComponentActivity required for permission handling (works with both Compose and traditional Activities)
callback: The callback to be invoked with the subscribe result. Returns success or failure of the subscription operation.
Usage
- Java
- Kotlin
PushEngage.subscribe(this, new PushEngageResponseCallback() {
@Override
public void onSuccess(Object result) {
Log.d("Subscription", "User subscribed successfully");
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
Log.e("Subscription", "Failed to subscribe: " + errorMessage);
}
});
PushEngage.subscribe(this, object : PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
Log.d("Subscription", "User subscribed successfully")
}
override fun onFailure(errorCode: Int?, errorMessage: String?) {
Log.e("Subscription", "Failed to subscribe: $errorMessage")
}
})
unsubscribe

Syntax
unsubscribe(PushEngageResponseCallback callback)
Parameters
callback: The callback to be invoked with the unsubscribe result.
result: A boolean indicating the unsubscription result.- Will be
trueif the unsubscription was successful. - Will be
falseif the unsubscription operation failed.

Associate Profile ID
Profile IDs serve as unique identifiers for your subscribers, enabling you to recognize them across multiple devices. Each subscriber can be assigned just one profile ID. This ID should be a string, and you have the flexibility to use any value, such as an email or phone number.
getSubscriberId
Retrieve the unique subscriber ID for a user. PushEngage generates this ID for every user based on their subscription data. Sometimes, this ID is referred to as the 'subscriber_hash'. The subscriber ID remains consistent unless there's a change in the user's subscription. If the user is not subscribed, it will return null.
Syntax
getSubscriberId(PushEngageResponseCallback callback)
Parameters
callback: The callback to be invoked with the subscriber ID result.
subscriberId: The unique subscriber ID for the user.- Will be a
Stringcontaining the subscriber ID if the user is subscribed. - Will be
nullif the user is not subscribed.
- Will be a
Usage
- Java
- Kotlin
PushEngage.getSubscriberId(new PushEngageResponseCallback() {
@Override
public void onSuccess(Object result) {
String subscriberId = (String) result;
if (subscriberId != null) {
Log.d("Subscriber", "Subscriber ID: " + subscriberId);
} else {
Log.d("Subscriber", "User is not subscribed");
}
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
Log.e("Subscriber", "Error getting subscriber ID: " + errorMessage);
}
});
PushEngage.getSubscriberId(object : PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
val subscriberId = responseObject as? String
if (subscriberId != null) {
Log.d("Subscriber", "Subscriber ID: $subscriberId")
} else {
Log.d("Subscriber", "User is not subscribed")
}
}
override fun onFailure(errorCode: Int?, errorMessage: String?) {
Log.e("Subscriber", "Error getting subscriber ID: $errorMessage")
}
})
addProfileId
This method allows you to set a profile ID for the current subscriber. If a profile ID already exists, it will be replaced with the new value.
Syntax
addProfileId(String profileId, PushEngageResponseCallback callback)
Parameters
profileId: A String representing the profile ID to be associated with the subscriber.
callback(optional): An interface designed as a callback to handle API responses asynchronously.
Usage
- Java
- Kotlin
PushEngage.addProfileId("your_id", new PushEngageResponseCallback() {
@Override
public void onSuccess(Object responseObject) {
//Handle the Success event.
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
//Handle the Failure event.
}
});
PushEngage.addProfileId("your_id", object : PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
//Handle the Success event.
}
override fun onFailure(errorCode: Int, errorMessage: String) {
//Handle the Failure event.
}
})
User Identity
The identify and logout methods manage the predefined personal-data fields stored on the current subscriber. Use them to tie a push subscription to your own first-party user data, and to clear that data on sign-out without unsubscribing the device.
The 12 valid keys are: first_name, last_name, email, phone, gender, dob, language, profile_id, country, city, state, zip. Values must be String, Number, or Boolean — other types are rejected client-side.
identify
Upsert one or more of the 12 predefined subscriber fields. If every requested field already matches the locally cached value (and the cache is fresh — within 24 hours of the last successful sync), the call short-circuits with onSuccess(null) and no network request is sent. A numeric profile_id is coerced to its string form before being sent.
Syntax
identify(JSONObject fields, PushEngageResponseCallback callback)
Parameters
fields: A JSONObject containing one or more of the 12 valid subscriber fields. Must contain at least one key.
callback (optional): An interface designed as a callback to handle API responses asynchronously.
Usage
- Java
- Kotlin
try {
JSONObject fields = new JSONObject();
fields.put("first_name", "Jane");
fields.put("last_name", "Doe");
fields.put("email", "[email protected]");
fields.put("profile_id", "user_12345");
PushEngage.identify(fields, new PushEngageResponseCallback() {
@Override
public void onSuccess(Object responseObject) {
//Handle the Success event.
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
//Handle the Failure event.
}
});
} catch (JSONException e) {
e.printStackTrace();
}
val fields = JSONObject().apply {
put("first_name", "Jane")
put("last_name", "Doe")
put("email", "[email protected]")
put("profile_id", "user_12345")
}
PushEngage.identify(fields, object : PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
//Handle the Success event.
}
override fun onFailure(errorCode: Int?, errorMessage: String?) {
//Handle the Failure event.
}
})
logout
Remove a set of predefined personal fields from the current subscriber while keeping the device subscribed for push. Call this when a user signs out of your app to detach their PII from the push subscription.
Passing null or an empty list removes the default PII field set: first_name, last_name, email, phone, gender, dob, profile_id. Passing a list of field names scopes the removal to those specific fields.
If none of the requested field names exist in the locally cached subscriber data (and the cache is fresh — within 24 hours of the last successful sync), the call short-circuits with onSuccess(null) and no network request is sent.
Syntax
logout(List<String> fieldNames, PushEngageResponseCallback callback)
Parameters
fieldNames: A List<String> of field names to remove. Pass null or an empty list to clear the default PII set.
callback (optional): An interface designed as a callback to handle API responses asynchronously.
Usage
Clear the default PII set:
- Java
- Kotlin
PushEngage.logout(null, new PushEngageResponseCallback() {
@Override
public void onSuccess(Object responseObject) {
//Handle the Success event.
}
@Override

Custom Events
trackEvent
Track a custom event for the current subscriber. Custom events are used to start or exit campaign workflows based on in-app activity — for example, adding an item to cart, completing a purchase, or any other action you define. Workflows are configured from the PushEngage Dashboard.
Syntax
trackEvent(TrackEvent event, PushEngageResponseCallback callback)
Parameters
event: A TrackEvent object describing the event payload.
| Field | Type | Required | Description |
|---|---|---|---|
eventName | String | Yes | Name of the event (e.g., "MySite.AddToCart"). |
data | Map<String, Object> | No | Custom key-value data. Values must be strings, numbers, or booleans — other types are rejected client-side with error code 400 before any network request is made. |
profileId | String | No | The profile ID of the subscriber. |
provider | String | No | Provider name. Defaults to "PushEngage". |
eventType | String | No | Event type. Defaults to "PushEngage.CustomEvent". |
callback (optional): An interface designed as a callback to handle API responses asynchronously.
Usage
- Java
- Kotlin
Map<String, Object> eventData = new HashMap<>();
eventData.put("product_id", "123");
eventData.put("product_name", "Product Name");
eventData.put("price", 49.99);
TrackEvent event = new TrackEvent("MySite.AddToCart", eventData);
PushEngage.trackEvent(event, new PushEngageResponseCallback() {
@Override
public void onSuccess(Object responseObject) {
//Handle the Success event.
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
//Handle the Failure event.
}
});
val eventData = mapOf<String, Any>(
"product_id" to "123",
"product_name" to "Product Name",
"price" to 49.99
)
val event = TrackEvent(eventName = "MySite.AddToCart", data = eventData)
PushEngage.trackEvent(event, object : PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
//Handle the Success event.
}
override fun onFailure(errorCode: Int?, errorMessage: String?) {
//Handle the Failure event.
}
})
Goal Tracking
Goal Tracking will help you assign conversion goals & value to your notification campaigns. You can set up a default goal and have it integrated for all your campaigns.
sendGoal
Syntax
sendGoal(Goal goal, PushEngageResponseCallback callback)
Parameters
goal: Goal object representing the goal to be tracked.
callback: An interface designed as a callback to handle API responses asynchronously.
Usage
- Java
- Kotlin
Goal goal = new Goal("name_of_goal", 1, 10.0);
PushEngage.sendGoal(goal, new PushEngageResponseCallback() {
@Override
public void onSuccess(Object responseObject) {
Toast.makeText(GoalActivity.this, "Goal Added Successfully", Toast.LENGTH_LONG).show();
}
@Override
public void onFailure(Integer errorCode, String errorMessage) {
Toast.makeText(GoalActivity.this, "Failure", Toast.LENGTH_LONG).show();
}
});
val goal = Goal("name_of_goal", 1, 10.0)
PushEngage.sendGoal(goal, object: PushEngageResponseCallback {
override fun onSuccess(responseObject: Any?) {
Toast.makeText(this@GoalActivity, "Goal Added Successfully", Toast.LENGTH_LONG).show()
}
override fun onFailure(errorCode: Int?, errorMessage: String?) {
Toast.makeText(this@GoalActivity, "Failure", Toast.LENGTH_LONG).show()
}
})
Utilities
getSdkVersion
Retrieves the current version of the PushEngage Android SDK, returning a string that represents the SDK's current version.
Syntax
getSdkVersion()
Returns
A String representing the current version of the PushEngage Android SDK.
Usage
- Java
- Kotlin
PushEngage.getSdkVersion();
PushEngage.getSdkVersion()
setSmallIconResource
Sets the resource name of the small icon used for notifications. The small icon appears in the status bar when a notification is displayed.
Syntax
setSmallIconResource(String resourceName)
Parameters
resourceName: A string representing the resource name of the small icon.
Usage
- Java
- Kotlin
String resourceName = "your_small_icon_name";
PushEngage.setSmallIconResource(resourceName);
val resourceName = "your_small_icon_name"
PushEngage.setSmallIconResource(resourceName)
It is recommended to set a valid resource name to ensure proper display of notifications. If an invalid resource name is provided, the default bell icon specified by the PushEngage library will be used.
setBadgeCount
Control the numeric badge associated with notifications the SDK builds afterwards. Android does not expose a system API for a numeric launcher-icon badge — only a dot indicator on supported launchers, plus a count surfaced in the long-press shortcut menu.
count == 0— clears all active notifications, which removes the launcher dot.count > 0— applied viaNotificationCompat.Builder.setNumber(count)to notifications the SDK builds afterwards; the value appears in the long-press menu.- Negative values are coerced to
0.
Syntax
setBadgeCount(int count)
Parameters
count: The badge count to set. Use 0 to clear.
Usage
- Java
- Kotlin
PushEngage.setBadgeCount(5);
// Clear the badge
PushEngage.setBadgeCount(0);
PushEngage.setBadgeCount(5)
// Clear the badge
PushEngage.setBadgeCount(0)
setFcmConfigErrorListener
Register a callback that fires when the SDK detects a mismatch between your app's local Firebase configuration and the configuration registered for your PushEngage site. Use this during integration to catch sender-ID or project-ID drift early — when a mismatch is detected at sync time, the SDK also skips the subscriber-add call so a permanently-undeliverable subscriber is not created on the server.
The listener is invoked with one of these error codes:
| Code | Constant | Meaning |
|---|---|---|
5001 | FCM_SENDER_ID_MISMATCH | google-services.json sender ID does not match the PushEngage dashboard. |
5002 | FCM_PROJECT_ID_MISMATCH | google-services.json project ID does not match the service-account JSON. |
5003 | FCM_LOCAL_CONFIG_INVALID | Firebase Installations rejected google-services.json as invalid for the app. |
5004 | FCM_CONFIG_BOTH_MISMATCH | Both sender ID and project ID differ from the dashboard configuration. |
The listener may be invoked on a background thread (OkHttp dispatcher, Firebase Installations callback, or the caller's thread). Marshal to the UI thread before touching UI.
Pass null to clear a previously-registered listener.
Syntax
setFcmConfigErrorListener(FcmConfigErrorListener listener)
Parameters
listener: The FcmConfigErrorListener to invoke on config errors, or null to clear.
Usage
- Java
- Kotlin
PushEngage.setFcmConfigErrorListener(new FcmConfigErrorListener() {
@Override
public void onFcmConfigError(int errorCode, String message) {
Log.e("PushEngage", "FCM config error " + errorCode + ": " + message);
}
});
PushEngage.setFcmConfigErrorListener { errorCode, message ->
Log.e("PushEngage", "FCM config error $errorCode: $message")
}
enableLogging
Enables or disables verbose debug logging for the SDK. When enabled, the SDK prints detailed logs to Logcat that are useful for diagnosing integration issues.
Disable logging in production builds to avoid leaking internal SDK state to device logs.
Syntax
enableLogging(boolean shouldEnable)
Parameters
shouldEnable: Pass true to turn on debug logging, false to turn it off.
Usage
- Java
- Kotlin
// Enable during development
PushEngage.enableLogging(true);
// Disable for production
PushEngage.enableLogging(false);
// Enable during development
PushEngage.enableLogging(true)
// Disable for production
PushEngage.enableLogging(false)
