LogCat में डेटा आउटपुट का प्रकार बदलें

मानक लकड़हारा पूरी तरह से सुविधाजनक नहीं है, कम से कम मेरे लिए। नीचे खुद के लिए एक लकड़हारा का एक उदाहरण है। मैं इसे डेढ़ साल से ज्यादा समय से इस्तेमाल कर रहा हूं। स्थानीय स्तर पर पाई जाने वाली समस्याओं को तेजी से देखने की अनुमति देता है, लॉगिंग की सुविधा देता है। अपनी आवश्यकताओं के लिए प्रक्रिया करना आसान है। जब काम करते हैं, तो इसे निरंतर टैगिंग या टैग को एक अलग कंटेंट बनाने की आवश्यकता नहीं होती है, क्योंकि एक स्वरूपित टैग स्वचालित रूप से जारी किया जाता है

> वर्ग: कार्य: पंक्ति संख्या

हम इसे इस तरह उपयोग करते हैं - Log.w("SUCCESS download")

> DownloadCharts: downloadSongs: 322: SUCCESS डाउनलोड

कभी-कभी यह पता लगाना आवश्यक है कि न केवल एक विशिष्ट त्रुटि का स्थान है, बल्कि मूल वर्ग भी है। तब माता-पिता के Log.w(this, "") साथ एक लकड़हारा बचाव में आता है, उदाहरण के लिए Log.w(this, "") तो हम लाइन प्राप्त करते हैं

> (पैरेंट) क्लास: फंक्शन: लाइन नंबर

> (ChartsLibrary) DownloadCharts: डाउनलोडसंग: 322: चेतावनी

हालाँकि, इसे एक बार आज़माना और परिणाम देखना आसान है।

बिल्ली के नीचे कोड है।
