I believe this code is right.

When I enter it, it kicks back, "did you forget to enter a method for getTileCount that accepts a Char?"

Anyone know what's wrong with this thing?

ScrabblePlayer.java 
public class ScrabblePlayer {
  private String mHand;

  public ScrabblePlayer() {
    mHand = "";
  }

  public String getHand() {
   return mHand;
  }

  public void addTile(char tile) {
    // Adds the tile to the hand of the player
    mHand += tile;
  }

  public boolean hasTile(char tile) {
   return mHand.indexOf(tile) > -1;
  }
  public String getTileCount() {
   String tileCount = ""; 
    for (char tile : mHand.toCharArray()) {
      char tilesInHand = tile;
      if (mHand.indexOf(tile) >= 0) {
      tilesInHand = tile;
    }
    tileCount += tilesInHand;
  }
    return tileCount;
  }
}

You should be able to pass in a char as an argument to the method getTileCount(). Your method will take the char passed in and count how many like tiles there are.

Also, I see that you have it returning a String; it should be returning an int.

Your method heading should look like this:

public int getTileCount(char tile){

}

Jeremy Hill is right about passing in the character, but you probably don't want to be using indexof. Think about what it does for a second. The relevant comparison is more likely to be comparing a received character against each character in your string using ==. see here if you want the exact code.
