Best Practices

Integration Guidelines

1. Early Initialization

// Initialize in Application.onCreate() for best performance
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        AlphynSDK.initialize(this);
    }
}

2. Proper Listener Management

// Always add listeners before initialization
AlphynSDK.addSecurityListener(securityListener);

// Remove listeners in onDestroy to prevent memory leaks
@Override
protected void onDestroy() {
    super.onDestroy();
    AlphynSDK.removeSecurityListener(securityListener);
}

3. Thread Safety

// SDK callbacks are delivered on the main thread
public void onSuccess(AlphynCallbackResult result) {
    // Safe to update UI directly
    updateUI(result);

    // For heavy processing, use background thread
    if (requiresHeavyProcessing(result)) {
        executorService.execute(() -> processResult(result));
    }
}

Error Handling

Comprehensive Error Handling Strategy:

public class ByteriaErrorHandler {
    private static final int MAX_RETRY_ATTEMPTS = 3;
    private static final long RETRY_DELAY_MS = 5000;

    public void handleError(AlphynCallbackResult result) {
        switch (result.getOriginalEventType()) {
            case INIT_FAILED:
                handleInitializationError(result);
                break;

            case NETWORK_ERROR:
                handleNetworkError(result);
                break;

            case KEYSTORE_FAILED:
                handleKeystoreError(result);
                break;

            case SCAN_FAILED:
                handleScanError(result);
                break;

            default:
                handleGenericError(result);
                break;
        }
    }

    private void handleInitializationError(AlphynCallbackResult result) {
        Log.e("Byteria", "Initialization failed: " + result.getMessage());

        // Check for common initialization issues
        if (result.getMessage().contains("invalid key")) {
            notifyInvalidKey();
        } else {
            scheduleRetryInitialization();
        }
    }

    private void handleNetworkError(AlphynCallbackResult result) {
        Log.w("Byteria", "Network error: " + result.getMessage());

        // Implement exponential backoff retry
        scheduleNetworkRetry();
    }

    private void scheduleRetryInitialization() {
        new Handler(Looper.getMainLooper()).postDelayed(() -> {
            // Retry initialization logic
            retryInitialization();
        }, RETRY_DELAY_MS);
    }
}

Performance Considerations

Memory Management:

public class PerformanceOptimizedListener implements AlphynSecurityListener {
    private final WeakReference<Activity> activityRef;

    public PerformanceOptimizedListener(Activity activity) {
        this.activityRef = new WeakReference<>(activity);
    }

    @Override
    public void onSuccess(AlphynCallbackResult result) {
        Activity activity = activityRef.get();
        if (activity != null && !activity.isFinishing()) {
            // Process result only if activity is still valid
            processResult(result);
        }
    }

    // Avoid holding strong references to prevent memory leaks
    private void processResult(AlphynCallbackResult result) {
        // Efficient result processing
        if (result.isSecurityScan()) {
            // Process scan results immediately
            handleScanResult(result.getScanResult());
        } else {
            // Queue other results for batch processing
            queueForBatchProcessing(result);
        }
    }
}

Efficient Event Processing:

public class BatchEventProcessor {
    private final List<AlphynCallbackResult> pendingEvents = new ArrayList<>();
    private final Handler batchHandler = new Handler(Looper.getMainLooper());
    private static final long BATCH_DELAY_MS = 100;

    public void queueEvent(AlphynCallbackResult result) {
        synchronized (pendingEvents) {
            pendingEvents.add(result);
            scheduleBatchProcessing();
        }
    }

    private void scheduleBatchProcessing() {
        batchHandler.removeCallbacks(batchProcessor);
        batchHandler.postDelayed(batchProcessor, BATCH_DELAY_MS);
    }

    private final Runnable batchProcessor = () -> {
        synchronized (pendingEvents) {
            if (!pendingEvents.isEmpty()) {
                processBatch(new ArrayList<>(pendingEvents));
                pendingEvents.clear();
            }
        }
    };
}
