我正在使用谷歌的firebase-database SDK for Android,v9.0.1.我将我的应用程序连接到Firebase,可以在不同位置读取和写入数据.

{

    "isUp": true,

    private boolean isUp;
    private long timestampMillis;

    public PingReport() {
        // required by Firebase
    }

    public PingReport(long durationMs, boolean isUp, long timestampMillis) {
        this.durationMs = durationMs;
        this.isUp = isUp;
        this.timestampMillis = timestampMillis;
    }

    public long getDurationMs() {
        return durationMs;
    }

    public boolean isUp() {
        return isUp;
    }

    public …
