परिचय

Google Play ActivityRecognitionAPI

यह GooglePlay सेवा की गतिविधिRecognitionApi का उपयोग करने का एक सरल उदाहरण है। हालाँकि यह एक महान पुस्तकालय है, यह उन उपकरणों पर काम नहीं करता है जिनमें Google Play Services स्थापित नहीं है।

PathSense गतिविधि मान्यता

PathSense गतिविधि मान्यता उन उपकरणों के लिए एक और अच्छी लाइब्रेरी है, जिनके पास Google Play Services नहीं है, क्योंकि उन्होंने अपना स्वयं का गतिविधि पहचान मॉडल बनाया है, लेकिन API कुंजी और क्लाइंट ID प्राप्त करने के लिए http://developer.pathsense.com पर डेवलपर्स रजिस्टर की आवश्यकता होती है। ।
