में काम नहीं कर रहा है, मैं 'स्टबप्रोवाइडर' और 'स्टबऑटेंटिकेटर' के साथ एक सिंक एडाप्टर लिखने की कोशिश कर रहा हूं, मैंने ऑफिकल दिशानिर्देशों का पालन किया, मेरा कोड बिना किसी त्रुटि के चल रहा है लेकिन 'onPerformSync()' बुलाया नहीं जा रहा है, मैंने सब कुछ करने की कोशिश की लेकिन कोई उपयोग नहीं किया।सिंक एडाप्टर में ContentResolver.requestSync एंड्रॉइड
मेरा पूरा परियोजना से https://www.dropbox.com/s/48bgj3wweehaieu/MyApplication.zip?dl=0

आप बहुत सारे कोड प्रदान कर रहे हैं, लेकिन वास्तव में क्या काम नहीं कर रहा है? कृपया वर्णन करें कि आप क्या हासिल करने की कोशिश कर रहे हैं, अपेक्षित परिणाम क्या है और वास्तविक परिणाम क्या है। –
