英文:

I have a code to get the current location of the user but some parts of the code says that it is deprecated

I tried copying other latest code but I also encountered some problems: https://stackoverflow.com/questions/76836062/google-maps-does-not-get-the-user-location-if-the-user-does-not-have-a-recent-lo

Then I tried reverting back to my old code though it is still working but I am quite worried that it may stop working at some point. Is there any code that I can replace with the deprecated code or latest codes that have the same function. I would greatly appreciate any insights or suggestions you might have. Thank you in advance for your help!

我替换它的代码是：

  1. locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 100)
  2. .setWaitForAccurateLocation(false)
  3. .setMinUpdateIntervalMillis(2000)
  4. .setMaxUpdateDelayMillis(100)
  5. .build();

旧的已废弃代码是：

  1. locationRequest = LocationRequest.create();
  2. locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
  3. locationRequest.setInterval(5000);
英文:

The codes that I replace it with is

  1.   locationRequest = new LocationRequest.Builder(Priority.PRIORITY_HIGH_ACCURACY, 100)
  2. .setWaitForAccurateLocation(false)
  3. .setMinUpdateIntervalMillis(2000)
  4. .setMaxUpdateDelayMillis(100)
  5. .build();

The old deprecated code is

  2. locationRequest = LocationRequest.create();
  3. locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
  4. locationRequest.setInterval(5000);
