发出许可请求后，无法在棉花糖中获取位置 [英] cannot fetch location in marshmallow after giving permission request

问题描述

我正在开发一个位置应用程序，该功能在除棉花糖以外的所有设备上都可以正常工作.我在运行时已请求权限，并且在我授予权限时未获取经度和纬度，如果我要进行设置并从高精度更改位置为了节省电池电量，可以提取位置并运行该应用程序.我希望以高精度获取位置.

I am developing an location app which is working fine in all devices except in Marshmallow.I have requested permission during runtime and when I grant permission longitude and latitude is not fetched,if i go to settings and change the location from high accuracy to battery saving,location is fetched and the app works.I want location to be fetched at high accuracy.

                   ActivityCompat.requestPermissions(this,
            new String[]{
                    Manifest.permission.CAMERA,
                    android.Manifest.permission.ACCESS_FINE_LOCATION,
                    android.Manifest.permission.ACCESS_COARSE_LOCATION,
                    android.Manifest.permission.ACCESS_WIFI_STATE,
                    Manifest.permission.INTERNET,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    Manifest.permission.READ_PHONE_STATE,
                    Manifest.permission.WAKE_LOCK,
            },
            1);

推荐答案

尝试一下

第1步:-在manifyingr文件中添加此权限

step 1 :- add this permission in manifiesr file

 android.Manifest.permission.ACCESS_FINE_LOCATION,
 android.Manifest.permission.ACCESS_COARSE_LOCATION,

第2步:要求运行时权限

 String permission = android.Manifest.permission.ACCESS_FINE_LOCATION;
            if (ActivityCompat.checkSelfPermission(SearchCityClass.this, permission)
                    != PackageManager.PERMISSION_GRANTED && ActivityCompat.
                    checkSelfPermission(SearchCityClass.this, android.Manifest.permission.ACCESS_COARSE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED) {
                ActivityCompat.requestPermissions(SearchCityClass.this, new String[]
                        {permission}, PERMISSION_GPS_CODE);

            }

第3步:处理渗透结果

 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == PERMISSION_GPS_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {


            Toast.makeText(this, location_permission_granted_msg, Toast.LENGTH_SHORT).show();

        } else {

            Toast.makeText(this, location_permission_not_granted_msg, Toast.LENGTH_SHORT).show();
        }
    }

}
