I'm a newbie to Android Studio IDE. I used to implement Android application, using Eclipse IDE. As a beginner in Android Studio, I tried this lesson from YouTube to include a external jar file to my project and use it. But unfortunately I'm unable to use that library even though the Gradle or Android build doesn't throw any error/exception when compile and run.
I've seen related questions from SO too. As an example, I've tried out things that discuss in this question.
In the build.gradle file, I used
compile files('libs/jsoup-1.7.3.jar')
and next time used
compile fileTree(dir: 'libs', include: '*.jar')
Neither work for me. After editing that build.gradle file, I used Sync Project With Gradle Files tools and also command line clean
gradlew clean
too. No error/exceptions, but when I try to write Docu... in my MainActivity class it doesn't show the import option org.jsoup.nodes, but show other imports options. What could be the mistake I've done.
