I simply copy & paste the code in the example. My activity contains a view pager. I get this exception:

java.lang.RuntimeException: insertShowcaseViewWithType cannot be used when the theme has no ActionBar at com.github.amlcurran.showcaseview.targets.ActionBarReflector.getHomeButton(ActionBarReflector.java:43) at com.github.amlcurran.showcaseview.targets.ActionBarReflector.getActionBarView(ActionBarReflector.java:36) at com.github.amlcurran.showcaseview.targets.ActionViewTarget.setUp(ActionViewTarget.java:38) at com.github.amlcurran.showcaseview.targets.ActionViewTarget.getPoint(ActionViewTarget.java:45) at com.github.amlcurran.showcaseview.ShowcaseView$1.run(ShowcaseView.java:191) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6119) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:886) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776)

I also tried this code:

    val target = ViewTarget(R.id.toolbarBottom, this)

    ShowcaseView.Builder(this, true)
            .setTarget(target)
            .setContentTitle("title")
            .setContentText("content").build()

And got this exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.getLocationInWindow(int[])' on a null object reference at com.github.amlcurran.showcaseview.targets.ViewTarget.getPoint(ViewTarget.java:41) at com.github.amlcurran.showcaseview.ShowcaseView$1.run(ShowcaseView.java:191) at android.os.Handler.handleCallback(Handler.java:751) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6119) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:886) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:776)
