process

abstract fun process(result: Result<T, E>)

Handles the result of an asynchronous operation.

This method is invoked on the main (UI) thread when an asynchronous SDK operation completes, regardless of whether it succeeded or failed. The Result parameter encapsulates either the successful result data or an exception describing the failure.

Thread safety: This method is always called on the main thread, making it safe to update UI components directly without posting to a handler or using runOnUiThread().

Usage pattern:

Check isSuccess to determine if operation succeeded
Use getData to access successful result (may be null for Void operations)
Use getException to access error information on failure

Example with push registration:


	  
	  public void process(@NonNull Result<RegisterForPushNotificationsResultData, RegisterForPushNotificationsException> result) {
	      if (result.isSuccess()) {
	          RegisterForPushNotificationsResultData data = result.getData();
	          String pushToken = data.getToken();
	          boolean notificationsEnabled = data.isEnabled();
	
	          Log.d("App", "Push token: " + pushToken);
	          Log.d("App", "Notifications enabled: " + notificationsEnabled);
	
	          // Update UI
	          statusTextView.setText("Push notifications enabled");
	      } else {
	          RegisterForPushNotificationsException exception = result.getException();
	          Log.e("App", "Registration failed: " + exception.getMessage(), exception);
	
	          // Show error to user
	          AlertDialog.Builder builder = new AlertDialog.Builder(this);
	          builder.setTitle("Registration Failed")
	              .setMessage("Unable to register for push notifications: " + exception.getMessage())
	              .setPositiveButton("Retry", (dialog, which) -> retryRegistration())
	              .setNegativeButton("Cancel", null)
	              .show();
	      }
	  }

Example with tags management:


	  
	  public void process(@NonNull Result<Void, PushwooshException> result) {
	      if (result.isSuccess()) {
	          // result.getData() is null for Void operations
	          Log.d("App", "Tags set successfully");
	          Toast.makeText(this, "Profile updated", Toast.LENGTH_SHORT).show();
	      } else {
	          PushwooshException exception = result.getException();
	          Log.e("App", "Failed to set tags: " + exception.getMessage(), exception);
	
	          // Determine error type and respond accordingly
	          if (exception.getMessage().contains("network")) {
	              Toast.makeText(this, "Network error. Please check your connection", Toast.LENGTH_LONG).show();
	          } else {
	              Toast.makeText(this, "Update failed. Please try again", Toast.LENGTH_SHORT).show();
	          }
	      }
	  }

Example with getting tags:


	  
	  public void process(@NonNull Result<TagsBundle, GetTagsException> result) {
	      if (result.isSuccess()) {
	          TagsBundle tags = result.getData();
	
	          // Safely access tag values with defaults
	          String userName = tags.getString("Name", "Guest");
	          int userAge = tags.getInt("Age", 0);
	          String subscription = tags.getString("Subscription", "free");
	
	          Log.d("App", "User: " + userName + ", Age: " + userAge + ", Plan: " + subscription);
	
	          // Update UI with user data
	          nameTextView.setText(userName);
	          subscriptionBadge.setText(subscription.toUpperCase());
	      } else {
	          GetTagsException exception = result.getException();
	          Log.e("App", "Failed to get tags: " + exception.getMessage(), exception);
	          // Show error or use cached data
	          loadCachedUserData();
	      }
	  }

Example with user ID operations:


	  
	  public void process(@NonNull Result<Void, SetUserIdException> result) {
	      if (result.isSuccess()) {
	          Log.d("App", "User ID set successfully");
	          // Continue with user initialization
	          loadUserProfile();
	          syncUserData();
	      } else {
	          SetUserIdException exception = result.getException();
	          Log.e("App", "Failed to set user ID: " + exception.getMessage(), exception);
	
	          // Critical error - user tracking won't work
	          AlertDialog.Builder builder = new AlertDialog.Builder(this);
	          builder.setTitle("Setup Error")
	              .setMessage("Failed to initialize user tracking. Some features may not work correctly.")
	              .setPositiveButton("Retry", (dialog, which) -> retryUserIdSetup())
	              .setNegativeButton("Continue Anyway", (dialog, which) -> continueWithoutTracking())
	              .setCancelable(false)
	              .show();
	      }
	  }
