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

您可能已经知道，Google Play 服务中有一个新的位置设置对话框 API.

对于不知道的人，这里是使用 Dialog API 的 Maps 应用的屏幕截图.

谷歌只在他们的播放服务中添加了该 API 有点不公平.另一方面，我认为如果他们能做到，就会有一种解决方法来做到这一点.这就是我问这个问题的原因.任何信息表示赞赏.

(注意:有一个漏洞可以让开发人员以编程方式启用和禁用 gps/位置设置.但是 SO 上可用的那些技巧不再有效.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() {@覆盖公共无效 onConnected(@Nullable 捆绑包){显示位置设置对话框()；}@覆盖公共无效 onConnectionSuspended(int i) {}}).addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {@覆盖公共无效 onConnectionFailed(@NonNull ConnectionResult 结果){Log.i(TAG, "onConnectionFailed() connectionResult = [" + result + "]");}}).建造();mGoogleApiClient.connect();}无效 showLocationSettingsDialog() {LocationRequest locationRequest = LocationRequest.create();locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();builder.addLocationRequest(locationRequest);builder.setAlwaysShow(true);任务<位置设置响应>结果 = LocationServices.getSettingsClient(getActivity()).checkLocationSettings(builder.build());result.addOnCompleteListener(new OnCompleteListener() {@覆盖公共无效onComplete(任务任务){尝试 {LocationSettingsResponse 响应 = task.getResult(ApiException.class);//满足所有位置设置.客户端可以初始化位置//在这里请求.} 捕捉(ApiException e){开关 (e.getStatusCode()) {案例 LocationSettingsStatusCodes.RESOLUTION_REQUIRED://位置设置不满足.但可以通过显示//用户一个对话框.尝试 {//强制转换为可解决的异常.ResolvableApiException 可解决 = (ResolvableApiException) e;//通过调用 startResolutionForResult() 显示对话框，//并在 onActivityResult() 中检查结果.resolvable.startResolutionForResult(获取活动()，REQUEST_CHECK_SETTINGS);} 捕捉(IntentSender.SendIntentException 异常){//忽略错误.} 捕捉(ClassCastException 异常){//忽略，应该是不可能的错误.}休息;案例 LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE://位置设置不满足.但是，我们没有办法修复//设置所以我们不会显示对话框.休息;}}}});}

对于更多信息 p>

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.)

解决方案

hi this works for me.

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;
                    }
                }
            }
        });
    }
