Common Appcelerator Titanium Issues and Fixes

1. "Titanium Build Failing"

Build failures may occur due to missing dependencies, incorrect SDK versions, or misconfigured environment settings.

Possible Causes

  • Incorrect Titanium SDK version or outdated dependencies.
  • Conflicting native modules or missing platform tools.
  • Improper environment variables for Android or iOS builds.

Step-by-Step Fix

1. **Ensure Correct Titanium SDK and CLI Version**:

# Checking installed Titanium SDK versionsti sdk list

2. **Update Dependencies and Clear Cache**:

# Updating Titanium CLI and SDKnpm install -g titaniumti sdk install latest

Module and Plugin Compatibility Issues

1. "Titanium Modules Not Working or Crashing"

Module compatibility issues may arise due to API changes, incorrect module versions, or missing dependencies.

Fix

  • Ensure the module version is compatible with the Titanium SDK version.
  • Manually clean the module cache and rebuild the project.
# Cleaning module cache and rebuilding the projectti cleanti build -p android

Performance Optimization

1. "Titanium App Running Slowly or Experiencing Lag"

Performance issues may be caused by excessive memory usage, slow rendering, or inefficient event handling.

Solution

  • Minimize excessive UI re-rendering and avoid deep UI hierarchies.
  • Use background threads for heavy computations.
// Using background threads for improved performancevar task = Ti.App.iOS.createBackgroundTask();setTimeout(function() {    Ti.App.iOS.endBackgroundTask(task);}, 5000);

Debugging and Logging Issues

1. "Titanium Logs Not Showing Detailed Errors"

Debugging issues may arise due to missing log levels or incorrect configurations.

Fix

  • Enable verbose logging for detailed debugging output.
  • Use adb logcat for Android debugging.
# Enabling verbose loggingti build -p android -l trace

Conclusion

Appcelerator Titanium enables cross-platform mobile development, but resolving build failures, ensuring module compatibility, optimizing performance, and improving debugging are crucial for efficient development. By following these troubleshooting strategies, developers can enhance Titanium’s stability and efficiency.
