I think you've answered that yourself.  If you are putting more work into moving unit of charge, then that unit of charge is going to move faster (all else being constant).  Current is the flow electric charge across a surface at specific rate (1 ampere = 1 coulomb per second) and hence - more voltage, more work, faster flow (rate), higher current.

Given Ohm's law, how can current increase if voltage increases, given fixed resistance?
While working with an android project .I'm stuck with R.java file which is not found even I clean the project(project---->clean).But that file still not found .Even I create a new project the same problem occurs .
what I need to do ? I'm expecting the valuable replies from which I could overcome this problem
