사용자에게 설정 페이지로 이동하여 위치 서비스를 활성화하고 다시 돌아 오도록 요청하는 전통적인 접근 방식과 달리 일부 최신 앱에서 동일한 작업을 수행하는 더 간단한 방법을 발견했습니다.

아래 스크린 샷을 참조하면 한 번의 클릭으로 위치 서비스를 활성화하라는 대화 상자가 사용자에게 표시되며 해당 앱에서 작동합니다.

어떻게 똑같이 할 수 있습니까?

이 대화 상자는 Google Play 서비스에서 사용할 수있는 LocationSettingsRequest.Builder에 의해 생성됩니다 .

앱에 종속성을 추가해야합니다 build.gradle.

compile 'com.google.android.gms:play-services-location:10.0.1'

그런 다음이 최소한의 예를 사용할 수 있습니다.

private void displayLocationSettingsRequest(Context context) {
    GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
            .addApi(LocationServices.API).build();
    googleApiClient.connect();

    LocationRequest locationRequest = LocationRequest.create();
    locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
    locationRequest.setInterval(10000);
    locationRequest.setFastestInterval(10000 / 2);

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

    PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
    result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
        @Override
        public void onResult(LocationSettingsResult result) {
            final Status status = result.getStatus();
            switch (status.getStatusCode()) {
                case LocationSettingsStatusCodes.SUCCESS:
                    Log.i(TAG, "All location settings are satisfied.");
                    break;
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    Log.i(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");

                    try {
                        // Show the dialog by calling startResolutionForResult(), and check the result
                        // in onActivityResult().
                        status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
                    } catch (IntentSender.SendIntentException e) {
                        Log.i(TAG, "PendingIntent unable to execute request.");
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    Log.i(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
                    break;
            }
        }
    });
}

여기 에서 전체 예를 찾을 수 있습니다 .

아래에 언급 된 단계를 따르십시오.

1)LocationRequest 원하는대로 만들기

LocationRequest mLocationRequest = LocationRequest.create()
           .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
           .setInterval(10 * 1000)
           .setFastestInterval(1 * 1000);

2) 만들기LocationSettingsRequest.Builder

LocationSettingsRequest.Builder settingsBuilder = new LocationSettingsRequest.Builder()
               .addLocationRequest(mLocationRequest);
settingsBuilder.setAlwaysShow(true);

3) 가져 오기 LocationSettingsResponse Task다음 코드를 사용하여

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

참고 : LocationServices.SettingsApi 는 더 이상 사용되지 않으므로 SettingsClient대신 사용하십시오 .

4) 작업OnCompleteListener 결과를 얻기 위해 a 를 추가 하고 Task완료되면 클라이언트는 LocationSettingsResponse객체 의 상태 코드를보고 위치 설정을 확인할 수 있습니다 .

result.addOnCompleteListener(new OnCompleteListener<LocationSettingsResponse>() {
    @Override
    public void onComplete(@NonNull Task<LocationSettingsResponse> task) {
    try {
        LocationSettingsResponse response = 
                          task.getResult(ApiException.class);
        } catch (ApiException ex) {
            switch (ex.getStatusCode()) {
                case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
                    try {
                        ResolvableApiException resolvableApiException = 
                                 (ResolvableApiException) ex;
                            resolvableApiException
                                   .startResolutionForResult(MapsActivity.this, 
                                         LOCATION_SETTINGS_REQUEST);
                    } catch (IntentSender.SendIntentException e) {

                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:

                    break;
            }
        }
    }
});  

사례 1 : LocationSettingsStatusCodes.RESOLUTION_REQUIRED : 위치가 활성화되어 있지 않지만 대화 상자 (를 호출하여 startResolutionForResult) 에서 위치를 켜도록 요청하여 사용자에게 위치를 활성화하도록 요청할 수 있습니다 .

CASE 2 : LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE : 위치 설정이 만족스럽지 않습니다. 그러나 설정을 수정할 방법이 없으므로 대화 상자를 표시하지 않습니다.

5) OnActivityResult 위치 설정 대화 상자에서 사용자 작업을 얻을 수 있습니다. RESULT_OK=> 사용자가 위치를 켰습니다. RESULT_CANCELLED-사용자가 위치 설정 요청을 거부했습니다.

최근 Marshmallow 업데이트에서는 위치 설정이 켜져 있어도 앱에서 명시 적으로 권한을 요청해야합니다. 이를 위해 권장되는 방법은 사용자가 필요에 따라 권한을 전환 할 수있는 앱의 권한 섹션을 표시하는 것입니다. 이를위한 코드 스 니펫은 다음과 같습니다.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
    
    if (this.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    
        final AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Location Permission");
        builder.setMessage("The app needs location permissions. Please grant this permission to continue using the features of the app.");
        builder.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_COARSE_LOCATION);
    
            }
        });
        builder.setNegativeButton(android.R.string.no, null);
        builder.show();
    }
} else {
    // do programatically as show in the other answer 
}

그리고 onRequestPermissionsResult아래와 같이 메서드를 재정의합니다 .

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
        switch (requestCode) {
            case PERMISSION_REQUEST_COARSE_LOCATION: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.d(TAG, "coarse location permission granted");
                } else {
                    Intent intent = new Intent();
                    intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                    intent.setData(uri);
                    startActivity(intent);
                }
            }
        }
    }

또 다른 접근 방식은 SettingsApi 를 사용하여 어떤 위치 공급자가 활성화되어 있는지 문의 할 수도 있습니다 . 활성화 된 항목이 없으면 앱 내에서 설정을 변경하라는 대화 상자를 표시 할 수 있습니다.

조사 중에 찾은 가장 간단한 방법은이 위치 요청 프로세스에 대한 Util 클래스를 만든 다음이를 호출하여 gps를 켜는 것입니다.
