एंड्रॉइड प्रोगार्ड इश्यू - अभी भी "java.io.IOException: कक्षा को संसाधित नहीं कर सकता ..." त्रुटि जब obfuscation छोड़ा जाता है

Question

मैं एंड्रॉइड स्टूडियो में प्रोग्रार्ड के साथ एक एंड्रॉइड ऐप बना रहा हूं और मेरे प्रोजेक्ट में लाइब्रेरी जार है (na .jar) कि मैं obfuscation और preverification छोड़ना चाहूंगा क्योंकि na.jar से कुछ वर्ग मुझे निर्माण के दौरान त्रुटियां दे रहे हैं। तो मेरी ProGuard कॉन्फ़िग फ़ाइल में, मैं निम्नलिखित विकल्पों के

-dontpreverify 

# com.na, org.json are packages in na.jar, don't obfuscate the code in these packages 
-keep class com.na.** { *; } 
-keep interface com.na.** { *; } 
-keep class org.json.** { *; } 
-keep interface org.json.** { *; } 

हालांकि मैं अभी भी निर्माण की प्रक्रिया के दौरान na.jar में दोषपूर्ण वर्गों से संबंधित निम्न त्रुटियों हो रही है।

तो क्या प्रोगार्ड अभी भी कक्षाओं और जारों को ओबफुसेशन छोड़ने के साथ पढ़ता है? मैं एंड्रॉइड ऐप बनाने के लिए प्रोगार्ड का उपयोग करने के लिए नया हूं।

अद्यतन # 1

-dontpreverify 
-dontoptimize 
-dontshrink 

-keep class com.na.** { *; } 
-keep interface com.na.** { *; } 
-keep class org.json.** { *; } 
-keep interface org.json.** { *; } 

Answer 1

इस प्रयास करें:

-dontwarn com.na.** 
-keep class com.na.** { *; } 
-keepattributes Signature 
-keepattributes Exceptions
