मैं एंड्रॉइड के लिए कैमरा ऐप बनाने की कोशिश कर रहा हूं लेकिन जब मैं तस्वीर लेने की कोशिश करता हूं, तो यह बग और मुझे करीब मजबूर होना पड़ता है। LogCat है:

मैं camera.takePicture(null, null, photoCallback); और camera.takePicture(ShutterCallback, rawCallback, photoCallback); दोनों की कोशिश की है, जैसा कि आप देख सकते हैं, और मैं भी कहीं पढ़ा है कि System.gc(); काम कर सकता था, लेकिन ऐसा नहीं हुआ। इसके अलावा, मैंने पढ़ा कि चित्र लेने के बाद पूर्वावलोकन को पुनरारंभ करना एक आम समस्या भूल रही थी, लेकिन मैं इसके बाद camera.startPreview(); पर कॉल कर रहा हूं, इसलिए मुझे नहीं पता कि क्या हो रहा है!
मैं एंड्रॉइड 2.3.3 (मोटोरोला रेजर) चला रहा हूं। (ऐसा लगता है कि एंड्रॉइड 2.3.3 पर कैमरे के साथ कई लोगों को समस्याएं आ रही हैं ...)।
अगर कोई मदद कर सकता है तो मैं वास्तव में आभारी रहूंगा!

मैं एक ऐप्लिकेशन है जो इस प्रवेश से पता चला है डाउनलोड करने के पूरी परियोजना अपलोड कर दिया है ... हो सकता है कि वहाँ कुछ यहाँ मदद कर सकता है है: यह की तरह लग रहा फाइल निर्देशिका बनाते समय समस्या आई। इसे कैसे हल किया जा सकता है?
