On the final day, we’ll optimize your AI-powered avatar assistant app for performance, size, and battery efficiency, and then package it for deployment to the Google Play Store and Apple App Store.
1. Why Optimize Before Deployment?
✅ Faster Performance → Reduces lag in voice, avatar, and chat processing.
✅ Lower Battery Usage → Reduces strain from camera, speech, and animations.
✅ Smaller App Size → Makes app downloads faster and lowers storage requirements.
✅ App Store Approval → App stores may reject apps with poor performance or privacy issues.
2. Performance Optimization Checklist
✅ Reduce GPT API Calls
Bundle multiple user inputs into one GPT API request for faster response:
const messageHistory = messages.slice(-5); // Last 5 for context
✅ Lower Avatar Render Frequency
Modify your useFrame
loop inside AvatarAnimation.js
:
let frameCount = 0;
useFrame(() => {
frameCount++;
if (frameCount % 2 !== 0) return; // Skip every alternate frame
// Avatar animation logic here
});
✅ Throttle Speech-to-Text & Emotion Analysis
Limit voice/emotion detection checks:
const detectEmotion = () => {
if (lastEmotionDetected && Date.now() - lastEmotionDetected < 2000) return; // Every 2s
lastEmotionDetected = Date.now();
// Voice emotion detection logic...
};
3. Reduce App Size
✅ Minimize TensorFlow Models
- Use lightweight versions of MediaPipe Hands and FaceMesh.
- Consider on-demand model loading:
await tf.setBackend('cpu'); // Lower-end devices
✅ Bundle Reduction in Metro
Modify metro.config.js
:
module.exports = {
transformer: {
minifierConfig: {
keep_classnames: false,
keep_fnames: false,
mangle: true,
output: { ascii_only: true },
},
},
};
4. Battery Optimization
✅ Stop Camera When Idle
Modify FaceExpressionDetector.js
and GestureDetector.js
:
useEffect(() => {
if (!isListening) cameraRef.current.pausePreview();
else cameraRef.current.resumePreview();
}, [isListening]);
✅ Reduce Continuous Processing
Lower background GPU usage:
if (!userInteracting) stopEmotionDetection();
5. Privacy & Permissions Checklist
✅ Microphone Access – For speech input.
✅ Camera Access – For face & gesture recognition.
✅ Explain Usage – Ensure App Store privacy form includes:
- Face/Hand Detection → “To enhance virtual assistant interactions.”
- Microphone → “For hands-free voice commands.”
6. Generating App Builds
✅ Android Build (Expo EAS)
eas build -p android
Follow Expo instructions to generate an APK/AAB.
✅ iOS Build (Expo EAS)
eas build -p ios
Requires Apple Developer Account.
7. Publishing to Google Play Store
- Create Developer Account – Google Play Console.
- Upload AAB – Release > Production > Upload your AAB file.
- Fill in Store Listing:
- Title: “AI Avatar Assistant: Voice & Emotion Chatbot”
- Description: “AI-powered voice assistant with 3D avatar, face tracking, and real-time chat.”
- Screenshots & Privacy Policy URL.
- Submit for Review.
8. Publishing to Apple App Store
- Create Apple Developer Account – Apple Developer.
- App Store Connect:
- Create new app > Upload IPA file from EAS Build.
- Fill app description, screenshots, privacy, and set permissions.
- Submit for Review.
9. Testing Before Submission
✅ Test on Real Devices → Android + iPhone.
✅ Test in Low Internet Conditions → Airplane mode + slow 3G.
✅ Check App Size:
