My Project shows no errors. Though when I run the application it says please fix the error before running your application. When I looked at Console tab it says
[2015-07-10 19:50:26 - Dex Loader] Unable to execute dex: Multiple dex files define Landroid/support/v7/app/ActionBar$DisplayOptions;
[2015-07-10 19:50:26 - NavigationDrawer] Conversion to Dalvik format failed: Unable to execute dex: Multiple dex files define Landroid/support/v7/app/ActionBar$DisplayOptions;
I tried searching for the solution but haven't got any.
this is what I have for my support libraries.
Please Help. I got stuck here. Thank you in advance.
You have added several times this same library try to delete it to get only one (android-support-v7-appcompat.jar).
I propose to remove last (at bottom) and first (at top).
I do not know how you android program does, but from my experience these types of errors is the beginning of many erroes own eclipse. I recommend migrate their projects to AndroidStudio an excellent IDE that works without any kind of bugs.
