为什么 requestLocationUpdates 会在接收时立即触发？

Question

当我像这样执行 requestLocationUpdates 时：

FusedLocationProviderClient fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(context);    

LocationRequest locationRequest = new LocationRequest();
locationRequest.setInterval(150000);
locationRequest.setFastestInterval(30000);
locationRequest.setMaxWaitTime(900000);
locationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
locationRequest.setSmallestDisplacement(0);

fusedLocationProviderClient.requestLocationUpdates(locationRequest, getPendingIntent(context));

然后onReceive(Context context, Intent intent) 会立即被解雇，而不会处理setMaxWaitTime(900000)。这是正常/记录在案的行为吗？

Answer 1

LocationUpdatesPendingIntent 中有一个小小的免责声明：

    // Sets the maximum time when batched location updates are delivered. Updates may be
    // delivered sooner than this interval.
    mLocationRequest.setMaxWaitTime(MAX_WAIT_TIME);
