LocationServices.SettingsApi已弃用

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);

    }

但不幸的是,不推荐使用LocationServices.SettingsApi.如何用新的代码替换已弃用的代码？

我找到了阅读文档,解决方案可以是使用SettingsClient,但无法弄清楚如何做到这一点.

有什么想法可以更新我的代码吗？

Answer 1

新代码是

 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.
                }
            }
        }
    });
}

LocationServices.SettingsApi已弃用

是的,LocationServices.SettingsApi已被弃用

如何用新的代码替换已弃用的代码？

您需要使用 基于GoogleApi的API SettingsClient

来自DOCS

SettingsClient

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

与位置设置启用程序API交互的主要入口点.

此API使应用程序可以轻松确保为应用程序的位置需求正确配置设备的系统设置.

在向位置服务发出请求时,设备的系统设置可能处于阻止应用程序获取其所需位置数据的状态.例如,可以关闭GPS或Wi-Fi扫描.这个意图使它很容易:

• 确定是否在设备上启用了相关的系统设置以执行所需的位置请求.

• (可选)调用一个对话框,允许用户通过单击启用必要的位置设置.

我找到了阅读文档,解决方案可以是使用SettingsClient,但无法弄清楚如何做到这一点.

按照以下步骤操作

要使用此API,首先要创建一个LocationSettingsRequest.Builder并添加该应用将使用的所有LocationRequests:

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

然后检查当前位置设置是否满足:

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

Answer 3

我在弃用LocationServices.SettingsApi和后使用此代码FusedLocationApi

此代码提供：

1）请求上一个位置

2）定期更新位置FusedLocationProviderClient

您活动中的所有代码

//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(){
                                @Override
                                public void onLocationResult(LocationResult locationResult) {
                                    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));
                                    }

                                }
                            },null);

                }
            } catch (ApiException exception) {
                switch (exception.getStatusCode()) {
                    case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                        // Location settings are not satisfied. But could be fixed by showing the
                        // user a dialog.
                        try {
