Showcaseview NoClassDefFoundError

问题

I added showcaseview jar into my project and use it like this

    ShowcaseView.ConfigOptions co = new ShowcaseView.ConfigOptions();
    co.hideOnClickOutside = true;

    ViewTarget target = new ViewTarget(R.id.button_start_game, this);
    ShowcaseView sv = ShowcaseView.insertShowcaseView(target, this, R.string.showcase_main_title, R.string.showcase_main_message, co);
    sv.setOnShowcaseEventListener(this);

but I have exception

82 line has

ShowcaseView sv = ShowcaseView.insertShowcaseView(target, this, R.string.showcase_main_title, R.string.showcase_main_message, co);

What could be the problem?

I'm a rookie Developer and I always seem to get stuck on things like this...

The solution is to not use a JAR, add the Showcaseview project as a library instead.

I solved this same issue by the following steps:

Import "Main" project that is in the "library" folder into my workspace from https://github.com/amlcurran/ShowcaseView
Right click the imported project from Step 1 and click properties>Android and check the "is library" box ![enter image description here][2]
Right click the project you want to use Showcaseview in and click properties>Android and click "Add"
Select the project from Step 1 and Click "OK" (Note: I have renamed mine to "Showcase" yours should be "Main" if you got the project from the Github link above)
Click Apply
Clean and Build

Enjoy less squiggly red lines!!!

I would post screen shots but this is my first SO post...

I also got the same error. As because i haven't included nineoldandroid library. Just download this library from http://nineoldandroids.com/ and add this library to your Project. Your Error resolves surely
