registerClick方法崩溃我的Android应用程序

Question

当我尝试触发registerClick方法时，应用程序崩溃了。

我将代码提交到此分支https://github.com/jackygrahamez/MayDay/tree/gear-fit

HomeActivity.java

    Bundle bundle=getIntent().getExtras();
    boolean startedByCUP=false;
    if(bundle!=null) {
        startedByCUP = bundle.getBoolean("START_BY_CUP");
        Log.e(">>>>>>", "START_BY_CUP");
        //multiClickEvent.registerClick(System.currentTimeMillis());
        multiClickEvent.registerClick(System.currentTimeMillis());
    }

MultiClickEvent.java     包com.mayday.md.trigger;

import android.util.Log;

public class MultiClickEvent {
public static final int TIME_INTERVAL = 10000;
private static final int TOTAL_CLICKS = 5;

private Long firstEventTime;
private int clickCount = 0;

public void reset() {
    firstEventTime = null;
    clickCount = 0;
}

public void registerClick(Long eventTime) {
    if (isFirstClick() || notWithinLimit(eventTime)) {
        firstEventTime = eventTime;
        clickCount = 1;
        return;
    }
    clickCount++;
    Log.e(">>>>>>", "MultiClickEvent clickCount = " + clickCount);
}

private boolean notWithinLimit(long current) {
    return (current - firstEventTime) > TIME_INTERVAL;
}

private boolean isFirstClick() {
    return firstEventTime == null;
}

public boolean isActivated() {
    return clickCount >= TOTAL_CLICKS;
}
}
