Courses Plus Student 201 PointsAndroid studio Logcat errors and unexpected results.
Been following through the create a blog reader app for android tutorials but the results I am getting are soon making me go to war with this Android Studio IDE. Why? Because, as i watch the video tutorials Ben Jakuben is getting different results in his Logcat and yet I do the same thing as he does.
I am very new to Android programming and I really don't know what most of the Logcat results mean. I seek your help.
