Why isn't my phone working?

The phone was charging with an adapter (end piece) in the wall and the adapter was really crappy and the adapter wires was visible and I adjusted the piece for the phone to charge, the adapter sparked/exploded, the cord is still working. But the phone continues to pop up with a "android.process.media. has stopped" message and I restarted the phone several times and took the battery out. Same thing happens. Please help me and answer back quickly pleaseeeee.
