位置服务的SettingsApi已经过时。

Question

我的代码是:

if (mGoogleApiClient == null && checkGooglePlayService()) {
        Log.d(Utils.TAG_DEV + TAG, "Building GoogleApiClient");
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
        mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
        mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
        builder.addLocationRequest(mLocationRequest);
        builder.setAlwaysShow(true);
        mLocationSettingsRequest = builder.build();
        PendingResult<LocationSettingsResult> result =
                LocationServices.SettingsApi.checkLocationSettings(
                        mGoogleApiClient,
                        mLocationSettingsRequest
                );
        result.setResultCallback(this);

    }

不幸的是，LocationServices.SettingsApi已被弃用。我该如何将旧代码替换为新代码？

我在阅读文档时发现解决方案可以使用SettingsClient，但我不知道该如何操作。

你有什么想法可以帮助我更新代码吗？

LocationServices.SettingsApi已过时

是的，LocationServices.SettingsApi已过时。

我该如何使用新代码替换过时的代码？

您需要使用基于GoogleApi的API SettingsClient。

来自文档：

SettingsClient

public class SettingsClient extends GoogleApi<Api.ApiOptions.NoOptions>

与位置设置启用器API进行交互的主要入口点。

该API使应用程序可以轻松确保设备的系统设置已正确配置为应用程序的位置需求。

在请求位置服务时，设备的系统设置可能处于阻止应用程序获取所需位置数据的状态。例如，GPS或Wi-Fi扫描可能已关闭。这个意图使以下操作变得容易：

- 确定设备上是否启用了相关的系统设置以执行所需的位置请求。 - 可选地，调用对话框，以使用户可以通过单击来启用必要的位置设置。

“我发现在阅读文档时解决方案是使用SettingsClient，但不知道如何实现。”

请按照以下步骤进行操作：

要使用此API，请首先创建一个LocationSettingsRequest.Builder，并添加应用程序将使用的所有LocationRequests：

LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
     .addLocationRequest(mLocationRequestHighAccuracy)
     .addLocationRequest(mLocationRequestBalancedPowerAccuracy)

然后检查当前位置设置是否符合要求：

Task<LocationSettingsResponse> result =
         LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());

新代码为

 protected void createLocationRequest() {
    LocationRequest mLocationRequest = LocationRequest.create();
    mLocationRequest.setInterval(10000);
    mLocationRequest.setFastestInterval(5000);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);

    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());

    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            Toast.makeText(MapActivity.this, "addOnSuccessListener", Toast.LENGTH_SHORT).show();
            // All location settings are satisfied. The client can initialize
            // location requests here.
            // ...
        }
    });

    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Toast.makeText(MapActivity.this, "addOnFailureListener", Toast.LENGTH_SHORT).show();
            if (e instanceof ResolvableApiException) {
                // Location settings are not satisfied, but this can be fixed
                // by showing the user a dialog.
                try {
                    // Show the dialog by calling startResolutionForResult(),
                    // and check the result in onActivityResult().
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(MapActivity.this,
                            REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException sendEx) {
                    // Ignore the error.
                }
            }
        }
    });

在LocationServices.SettingsApi和FusedLocationApi被弃用后，我使用了以下代码：

这段代码提供了以下功能：

1) 请求最新位置信息

2) 使用FusedLocationProviderClient周期性地更新位置信息

将所有代码放在您的Activity中。

//create this at top of onCreate 
private FusedLocationProviderClient mFusedLocationClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //...
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
    //ADD THIS LINE
    mFusedLocationClient  = LocationServices.getFusedLocationProviderClient(this);
    buildGoogleApiClient();
    createLocationRequest();
    Loc_Update();
    //...
}



protected synchronized void buildGoogleApiClient() {
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
                @Override
                public void onConnected(@Nullable Bundle bundle) {
                    if (ActivityCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                        mFusedLocationClient.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {
                            @Override
                            public void onSuccess(Location location) {
                                if (location!=null){
                                    LatLng loc = new LatLng(location.getLatitude(), location.getLongitude());
                                    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f));
                                }
                            }
                        });
                    }
                }

                @Override
                public void onConnectionSuspended(int i) {
                    //LOG
                }
            })
            .addApi(LocationServices.API)
            .build();
}
protected void createLocationRequest() {
    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(30000);
    mLocationRequest.setFastestInterval(10000); 
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
}

private void Loc_Update() {
    LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);
    Task<LocationSettingsResponse> task = LocationServices.getSettingsClient(this).checkLocationSettings(builder.build());
    task.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
        @Override
        public void onComplete(@NonNull Task<LocationSettingsResponse> task) {
            try {
                LocationSettingsResponse response = task.getResult(ApiException.class);
                // All location settings are satisfied. The client can initialize location
                // requests here.
                if (ContextCompat.checkSelfPermission(MainMapActivity.this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {

                    mFusedLocationClient.requestLocationUpdates(mLocationRequest,new LocationCallback(){

                                    for (Location location : locationResult.getLocations()) {
                                        //Do what you want with location
                                        //like update camera
                                        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 16f));
                                    }

                                }

                        // user a dialog.
