在不使用Play Services API的情况下启用位置/GPS设置 [英] Enable Location/GPS settings without using Play Services API

问题描述

众所周知，大多数人在Google Play服务中都有一个新的位置设置对话框" API.

对于那些不知道这里的人，是使用Dialog API的Maps应用的屏幕截图.

Google只是在其播放服务中添加了该API，这有点不公平.另一方面，我认为如果他们能够做到，那就会有解决方法.这就是为什么我问这个问题.任何信息表示赞赏.

(注意:有一个漏洞可让开发人员以编程方式启用和禁用gps/位置设置.但是，SO上可用的这些技巧不再起作用.请不要发布过时的答案.)

解决方案

这对我有用.

void initApiClient() {
        GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addApi(LocationServices.API)
                .addConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
                    @Override
                    public void onConnected(@Nullable Bundle bundle) {
                        showLocationSettingsDialog();
                    }

                    @Override
                    public void onConnectionSuspended(int i) {

                    }
                })
                .addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
                    @Override
                    public void onConnectionFailed(@NonNull ConnectionResult result) {
                        Log.i(TAG, "onConnectionFailed() connectionResult = [" + result + "]");
                    }
                })
                .build();
        mGoogleApiClient.connect();
    }

    void showLocationSettingsDialog() {

        LocationRequest locationRequest = LocationRequest.create();
        locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
        builder.addLocationRequest(locationRequest);
        builder.setAlwaysShow(true);

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

        result.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
            @Override
            public void onComplete(Task<LocationSettingsResponse> task) {
                try {
                    LocationSettingsResponse response = task.getResult(ApiException.class);
                    // All location settings are satisfied. The client can initialize location
                    // requests here.
                } catch (ApiException e) {
                    switch (e.getStatusCode()) {
                        case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                            // Location settings are not satisfied. But could be fixed by showing the
                            // user a dialog.
                            try {
                                // Cast to a resolvable exception.
                                ResolvableApiException resolvable = (ResolvableApiException) e;
                                // Show the dialog by calling startResolutionForResult(),
                                // and check the result in onActivityResult().
                                resolvable.startResolutionForResult(
                                        getActivity(),
                                        REQUEST_CHECK_SETTINGS);
                            } catch (IntentSender.SendIntentException exception) {
                                // Ignore the error.
                            } catch (ClassCastException exception) {
                                // Ignore, should be an impossible error.
                            }
                            break;
                        case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                            // Location settings are not satisfied. However, we have no way to fix the
                            // settings so we won't show the dialog.
                            break;
                    }
                }
            }
        });
    }

As most of you might already known there is a new Location Settings Dialog API in Google Play Services.

For those who don't know here is the screenshot of Maps app which used Dialog API in action.

It is kinda unfair that google only added that API inside their play services. On the other hand, I think if they could do it, there would be a workaround to do it. That's why I am asking this question. Any information is appreciated.

(Note: There was an exploit which let developers to enable and disable gps/location setting programmatically. However those tricks available on SO no longer works. Please don't post outdated answers.)

hi this works for me.

void initApiClient() {
        GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addApi(LocationServices.API)
