मैं वीडियो रिकॉर्डिंग ऐप पर काम कर रहा हूं जिसमें मैं पूर्वावलोकन प्रदर्शित करना चाहता हूं और जब उपयोगकर्ता रिकॉर्ड बटन पर क्लिक करता है तो यह रिकॉर्डिंग शुरू करता है और जब उपयोगकर्ता स्टॉप बटन पर क्लिक करता है तो यह रिकॉर्डिंग बंद कर देता है।मीडिया रिकॉर्डर कैमरा के लिए एंड्रॉइड में विफल रहा
मैं अपने सतह पर वीडियो पूर्वावलोकन मिल गया लेकिन जब मैं शुरू बटन दबाएँ यह त्रुटि "MEDIA.RECORDER.START (मूल निवासी विधि) के साथ दुर्घटना। यहाँ मेरी कोड कृपया मुझे लोग मदद है।
