I have a class which extends surfaceview and from that class I start another activity, after few times the app crashes.

This is my LogCat:

Code from Leidejas.java class:

        vaizdas.yk += 0.0005;
        }

        //play sound
        if(musicid!=0)
        sp.play(musicid, 1, 1, 0, 0, 1);

        }else if(y>y1){

                }

            //play sound
            if(musicid!=0)
            sp.play(musicid, 1, 1, 0, 0, 1);

        }
        break; 
        }



        return true;
    }


}

Please help me fix the crashing problem!
