Appxiom Issue Callback Listener - Code level Error Detection Notification

The Appxiom SDK provides a powerful callback listener system that enables real-time monitoring of all issues detected in your Android application. Use the Ax.listenForIssue() API to implement custom error handling, logging, or user notification systems.

Step 1: Register the Global Listener

Add the issue listener in your Application class onCreate() method. Register only a single global listener to receive callbacks for all issues detected by the SDK.

Application Class Implementation:

Java
Kotlin

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        
        // Initialize Appxiom SDK
        Ax.init(this, appKey, platformKey);
        
        // Register global issue listener
        Ax.listenForIssue(new IssueFoundListener() {
            @Override
            public void issueFoundInBackgroundThread(IssueView issue) {
                // Handle issue detection
                handleIssueDetected(issue);
            }
        });
    }
    
    private void handleIssueDetected(IssueView issue) {
        // Custom issue handling logic
        Log.d("AppxiomIssue", "Issue detected: " + issue.getDetailedDescription());

        // Switch to UI thread for UI operations
        new Handler(Looper.getMainLooper()).post(() -> {
            // Update UI or show notifications
            showIssueNotification(issue);
        });
    }
}

class MyApplication : Application() {
    override fun onCreate() {
        super.onCreate()
        
        // Initialize Appxiom SDK
        Ax.init(this, appKey, platformKey)
        
        // Register global issue listener
        Ax.listenForIssue { issueView ->
            // Handle issue detection
            handleIssueDetected(issueView)
        }
    }
    
    private fun handleIssueDetected(issue: IssueView?) {
        issue?.let {
            // Custom issue handling logic
            Log.d("AppxiomIssue", "Issue detected: ${it.detailedDescription}")

            // Switch to UI thread for UI operations
            Handler(Looper.getMainLooper()).post {
                // Update UI or show notifications
                showIssueNotification(it)
            }
        }
    }
}

Step 2: Implement Custom Issue Handling

The callback provides an IssueView object containing issue properties that are synchronized to the server, ensuring complete transparency in the monitoring process.

Important Threading Considerations:

The callback executes in a background thread
Use UI thread (Handler/runOnUiThread) for UI-related operations, if needed.
The callback triggers immediately after issue occurrence
