Common AppGyver Issues and Solutions

1. App Crashes or Freezes

AppGyver applications may crash or become unresponsive during runtime.

Root Causes:

• Excessive memory usage due to large components.
• Incorrect use of logic flows leading to infinite loops.
• Incompatibility with specific device configurations.

Solution:

Monitor app logs for error messages:

console.log("App Started");

Optimize logic flow execution:

Ensure loops and conditions are correctly structured to prevent infinite execution.

Reduce memory usage by optimizing large lists:

Use pagination for data-heavy lists instead of loading all items at once.

2. Data Binding Issues

AppGyver may fail to correctly bind data to UI components.

Root Causes:

• Incorrect variable scope selection.
• Missing data updates before rendering.
• Inconsistent JSON structure from APIs.

Solution:

Ensure the correct variable scope is used:

App Variables: Used for global state.Page Variables: Used for page-specific data.Data Variables: Used for API-based data fetching.

Manually trigger data refresh:

refreshData();

Validate API response structure:

if (!response.hasOwnProperty("data")) {  console.error("Invalid API Response");}

3. Slow Performance in AppGyver

Apps built with AppGyver may exhibit slow UI performance and laggy interactions.

Root Causes:

• Unoptimized use of heavy animations.
• Excessive logic flow executions.
• Loading too much data at once.

Solution:

Reduce animation complexity:

Limit the number of animations running simultaneously.

Optimize logic flow by debouncing function calls:

setTimeout(() => {  executeLogic();}, 300);

Use pagination and lazy loading for large datasets.

4. Deployment Issues

AppGyver apps may fail to build or deploy properly.

Root Causes:

• Incorrect build configurations.
• Missing platform-specific settings for Android/iOS.
• Failure in authentication for cloud deployment.

Solution:

Verify build configurations:

Check the AppGyver Build Service for error logs.

Ensure iOS/Android settings are correctly set:

Update bundle ID and signing credentials in AppGyver settings.

Check authentication credentials for cloud deployment.

5. Third-Party API Integration Issues

APIs may fail to fetch data correctly within AppGyver applications.

Root Causes:

• Incorrect API endpoint configuration.
• Missing authentication headers.
• CORS policy restrictions.

Solution:

Validate API endpoints:

fetch("https://api.example.com/data")  .then(response => response.json())  .then(data => console.log(data));

Ensure authentication headers are included:

fetch("https://api.example.com/data", {  headers: { "Authorization": "Bearer YOUR_TOKEN" }});

Check CORS policy errors in the browser console.

Best Practices for AppGyver Development

• Use pagination for large datasets to improve performance.
• Optimize logic flows to avoid unnecessary executions.
• Ensure API response structures are consistent.
• Verify deployment settings before submitting builds.
• Use proper variable scopes for data management.

Conclusion

By troubleshooting app crashes, data binding failures, performance bottlenecks, deployment errors, and third-party API integration challenges, developers can efficiently build applications using AppGyver. Implementing best practices ensures smooth mobile development and optimal app performance.
