मैं तालिका में मान डालने की कोशिश कर रहा हूं। लेकिन केवल एक मान डाला गया है। जब मैं नए मान डालने की कोशिश कर रहा हूं तो मुझे लॉग बिल्ली में त्रुटि मिल रही है।अद्वितीय बाधा विफल: एसक्लाइट डेटाबेस: एंड्रॉइड
लॉग बिल्ली दिखाता है:

यह कैसे हल करने के लिए ??
आप पहले से ही मौजूदा आईडी डालने का प्रयास कर रहे हैं। चूंकि कुंजी अद्वितीय है, आप नहीं कर सकते हैं। –
मुझे किस कोड को संपादित करना चाहिए? @ हुरुंडी वी। बक्षी –
मैं कुंजी को एक ऑटोमेशन बनाउंगा। और फिर मैं आईडी पास नहीं करूंगा, क्योंकि यह स्वचालित रूप से जेनरेट हो जाएगा। –
