您可以检查代码:DialpadFragment.java--ToneGenerator:
private void playTone(int tone, int durationMs)
private void stopTone()
ToneGenerator停止超时导致ANR。但是ToneGenerator导致停止超时的原因是什么?如何分析和解决此问题?
答案 0 :(得分:0)
您可以为我简单地使用它及其工作
ToneGenerator toneG = new ToneGenerator(AudioManager.STREAM_ALARM, 100);
toneG.startTone(ToneGenerator.TONE_CDMA_ALERT_CALL_GUARD, 200);
