  • 0

I just tried to use achartengine demo, but every time I click on something to show the chart appears an error saying “The application AChartengine has stopped unexpectedly. Please try again”. Someone knows to tell me how can I do? I followed the instructions suggested in this page http://www.achartengine.org/content/goodies.html and I use an emulator standard with api level 7. I have these errors:

    See this for a solution to this:

    In Eclipse:
    -> Right click your project – go to build path – select Configure build path
    -> go to the “Order and Export” tab
    -> Check the “achartengine-1.0.0.jar box and then single click its name
    -> move it up so its right below the Android dependancies (sometimes this
    can make a difference if you have multiple Jars)

    click ok then clean your project. (Project -> Clean…)

    Try running it again and see if that helps.
