android – The application AChartengine has stopped unexpectedly. Please try again

Posted by: admin May 14, 2020 Leave a comment

Questions:

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:

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.

Answer:

if you want to know how achartengine work then add the achartengine 0.7.0 jar to libs folder and link it with your project also have these below activity.

public class GeneratedChartDemo extends ListActivity {
  private static final int SERIES_NR = 2;

    // getString(R.string....)
    mMenuText = new String[] { "Line chart", "Scatter chart", "Time chart", "Bar chart" };
   setListAdapter(new SimpleAdapter(this, getListValues(), android.R.layout.simple_list_item_1,
