में बदल गया है, मैं स्पष्ट रूप से अपने लाइनरलायआउट (@android: रंग/काला का उपयोग करके अपने एक्सएमएल में) का एक काला रंग परिभाषित कर रहा हूं, लेकिन कभी-कभी (अक्सर स्क्रीन रोटेशन के बाद), काला है एक ग्रे रंग (या एक पारदर्शी काला) में बदलना।एंड्रॉइड - ब्लैक बैकग्राउंड ग्रे
यह समस्या कई उपकरणों पर दिखाई देती है: एमुलेटर, एसर तरल (एंड्रॉइड 2.2) और गैलेक्सी नेक्सस (एंड्रॉइड 4.1) दोनों पर।

मदद के लिए धन्यवाद!
इसके लिए उचित समाधान क्या है? या मैं कहूंगा कि इसके लिए कोई उचित समाधान है? और क्या Google बग ट्रैकर पर कुछ है? –
