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 int getTileCount(char tile) {
   int count = 0;
     for (char tile: mHand.toCharArray()) {
      count++;  
     }
    return count;

The Preview shows this error:

./ScrabblePlayer.java:23: error: variable tile is already defined in method getTileCount(char)
     for (char tile: mHand.toCharArray()) {
               ^
1 error

You use tile as the formal parameter and then again as the variable for the for-each loop.

The other problem is that you loop though the tiles in mHand, but you don't compare them to the formal parameter. Try this instead:

  public int getTileCount(char tile) {
   int count = 0;
     for (char t: mHand.toCharArray()) {
        if (t == tile) {
          count++;  
        }
     }
    return count;
  }
