구형 기기에서만 팅깁니다.

Question

Timer timer = new Timer();
TimerTask timerTask = new TimerTask() {
    @Override
    public void run() {
        a += b;
        textViewA.setText("텍스트A " + a);
        textViewB.setText("텍스트C : " + c);
        textViewC.setText("텍스트B : " + b);
    }
};
timer.schedule(timerTask, 1000 , 1000); // 1초마다 골드내역 갱신

타이머에서 멈추는거 같은데

AVD(Nexus 5X API 28)랑 갤럭시S7에서는 문제없이 되는데

그랜드맥스로 테스트해보려고 하니까 팅겨버리네요

아래는 로그입니다

어디가 문제일까요

그랜드맥스는 4.4.4 킷캣입니다.
