Question

我正在开发一个应用程序，我想要获取用户设备的lat，lng。我发现我需要Access_Fine_Location权限以及Access_Coarse_Location，我知道我应该在期间要求它们运行时以及将它们包含在我的AndroidManifest.xml中，但应用程序只询问我的权限ACCESS_COARSE_LOCATION，并忽略询问ACCESS_FINE_LOCATION。这是我的代码

 private boolean checkAndRequestPermissions(){
    int permissionReadContacts = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS);
    int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION);
    int locationPermission2 =ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);

    List<String> listPermissionsNeeded = new ArrayList<String>();
    if (locationPermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.ACCESS_COARSE_LOCATION);
    }

    if (locationPermission2 != PackageManager.PERMISSION_GRANTED) {
        Log.i("addingPerm","addingPerm");
        listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
    }

    if (permissionReadContacts != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.READ_CONTACTS);
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;

}

这里是回调：

@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    String TAG = "sonder.SplashActivity";
    Log.d(TAG, "Permission callback called-------");
    switch (requestCode) {
        case REQUEST_ID_MULTIPLE_PERMISSIONS: {

            Map<String, Integer> perms = new HashMap<String, Integer>();
            // Initialize the map with both permissions
            perms.put(Manifest.permission.ACCESS_COARSE_LOCATION, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.ACCESS_FINE_LOCATION, PackageManager.PERMISSION_GRANTED);
            perms.put(Manifest.permission.READ_CONTACTS, PackageManager.PERMISSION_GRANTED);

            // Fill with actual results from user
            if (grantResults.length > 0) {
                for (int i = 0; i < permissions.length; i++)
                    perms.put(permissions[i], grantResults[i]);
                // Check for both permissions

                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                    LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
                    LocationListener locationListener = new LocListener();
                    locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 5000, 10, locationListener);
                    UserData.setLocation(LocListener.getLat() + "," + LocListener.getLon());
                    Log.i("aaaaaaaaaa", "aaaaaaaaaa");
                    Log.i("" + LocListener.getLat(), "" + LocListener.getLon());

                    if (perms.get(Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                        Log.i("Ahmed", "Ahmed");
                        Log.d("Permissions", "location services permission granted");
                        FacebookSdk.sdkInitialize(getApplicationContext());
                        Thread myThread = new Thread() {
                            @Override
                            public void run() {
                                try {
                                    Log.i("May", "May");
                                    sleep(300);
                                    Intent intent = new Intent(getApplicationContext(), setup_activity.class);
                                    startActivity(intent);
                                    finish();
                                } catch (InterruptedException e) {
                                    e.printStackTrace();
                                }
                            }
                        };
                        myThread.start();
                    } else {
                        //If permissions are denied
                        Log.d(TAG, "Location permission not granted ask again");
                        Intent intent = new Intent(getApplicationContext(), setup_activity.class);
                        startActivity(intent);
                        finish();
                    }
                }
            }
        }
    }
}

这是我的AndroidManifest.xml

Answer 1

您的三个<uses-permission>元素的权限名称不正确。没有以android.permissions开头的Android SDK权限（请注意最后的s）。因此，例如，您需要将android.permissions.ACCESS_FINE_LOCATION更改为android.permission.ACCESS_FINE_LOCATION。如果<uses-permission>元素缺失或无效，则无法请求运行时权限。

Android：在运行时获取设备位置
