延迟运行时间从未调用过

Question

我尝试这样做 Android LocationRequest: get a callback when request expires

在片段中我有这段代码

        @NonNull
protected Handler sHandler = new Handler(CoreApp.getContext().getMainLooper());
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    sHandler.postDelayed(mExpiredRunnable, 5000);
}
final Runnable mExpiredRunnable = new Runnable() {
    @Override
    public void run() {
        System.out.println("aaa");
    }
};

片段，一切正常。我有LocationHelper类，该类具有使用位置的方法。在locationHelpetr中，我有此代码

    @NonNull
protected Handler sHandler = new Handler(CoreApp.getContext().getMainLooper());
final Runnable mExpiredRunnable = new Runnable() {
    @Override
    public void run() {
        System.out.println("aaa konec");
        mOnSuccessLocationListener.onSuccess(null);
    }
};
public void startLocationUpdates() {
    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setInterval(5000);
    locationRequest.setFastestInterval(5000);
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setExpirationDuration(15000);

    mFusedLocationClient.requestLocationUpdates(locationRequest, mLocationCallback, null);

    if (mListener != null) {
        mFusedLocationClient.getLastLocation().addOnSuccessListener(mOnSuccessLocationListener);
        sHandler.postDelayed(mExpiredRunnable, 5000);
    }
}

mExpireRunnable从未在locationHelper中调用。片段中一切正常。
