The project cannot be built until build path errors are resolved

While i m run a project in android i got the following error which is

Description Resource    Path    Location    Type

The project cannot be built until build path errors are resolved    Projectname

Unknown Java Problem

Unbound classpath container: 'JRE System Library [JavaSE-1.7]' in project 

'Projectname'   Projectname       Build path  Build Path Problem

For this we want to do the following

Right the Package Explorer and choose Build Path 

Choose Build Path Configuration

Choose Libraries 

Then Add Library and JRE System Library and click next

Select Execution Environment in that choose your appropriate JRE here i m using jre8

And finally click Finish button and build your project.


Thanks Stackoverflow
