मैं बाहर काम नहीं कर सकता क्यों मेरे objFragment समर्थन प्रबंधक के साथ मुझे मुद्दों दे रहा है, मैं इस त्रुटि हो रही है:ओबीजे फ्रैगमेंट गलत 2 तर्क प्रकार 'Android.support.V4.app.Fragment' मिला। आवश्यक 'Android.app.Fragment'
Error:(101, 17) error: no suitable method found for replace(int,android.support.v4.app.Fragment)
method FragmentTransaction.replace(int,android.app.Fragment,String) is not applicable
(actual and formal argument lists differ in length)
method FragmentTransaction.replace(int,android.app.Fragment) is not applicable
(actual argument android.support.v4.app.Fragment cannot be converted to android.app.Fragment by method invocation conversion)
और उस पर objFragment पर इस पर क्या हो रहा है इस लाइन:
