of type org.json.JSONObject cannot be converted to JSONArray
करने के लिए छवि डाउनलोड कर सकते हैं मैं सुझाव देता हूं कि आप जो कुछ जानते हैं उसके साथ प्रयास करना एक वैध JSONArray है यह सुनिश्चित करने के लिए कि आपका कोड काम करता है और फिर यह देखने के लिए जांच कर रहा है यह वास्तव में एक वैध JSONArray है। आप Google Chrome के "JSON Formatter" एक्सटेंशन जैसे टूल का उपयोग कर सकते हैं ताकि आप इंडेंट, स्वरूपित तरीके से JSON को पढ़ने में मदद कर सकें –
