परिचय

गतिविधि की पहचान डिवाइस पर कुछ कार्यों को करने के लिए उपयोगकर्ता की शारीरिक गतिविधि का पता लगाने के लिए है, जैसे कि किसी ड्राइव का पता चलने पर अंक लेना, फोन चालू होने पर वाईफाई बंद करना या उपयोगकर्ता द्वारा अधिकतम होने पर रिंग वॉल्यूम को अधिकतम करना। घूमना।

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। ।
