Answer 1

問題は、あなたがintとしてテキストを設定しているどこかにあります。下の行のように

highScoreText.setText（currentPlayer.getHighScore（））;

getHighScore（）の戻りintはその後、OSはあなたの.resources $ NotFoundException与えるstring.xmlを内のリソースを探します場合

。以下のように使ってみてください。

highScoreText.setText(String.valueOf(currentPlayer.getHighScore())); 

それとも

highScoreText.setText(currentPlayer.getHighScore()+"");
