I'm working in an Android app, and I have declared the method requestAppPermissions in my Activity.
Well, what happened with this code, for some reason, it's requesting the first one (in this case, location) and skip the others; but, I move some other permission to the first if the method is requesting the first one, skipping the others.
What I have wrong with my code?
public void requestAppPermissions(){
    if (Build.VERSION.SDK_INT >= 21) {
        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.ACCESS_FINE_LOCATION)) {
                //El usuario denegó los permisos con el botón "Don't show again!!!"
                startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));
            } else {
                //Se solicita el permiso al usuario
                ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION}, 1);
            }
        }else{
            LocationManager lm = (LocationManager) this.getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
            Location location = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if(location != null){
                Double latitude = location.getLatitude();
                Double longitude = location.getLongitude();
                //new MapFunctions().RecenterMap(googleMap, new LatLng(latitude, longitude), 14, "");
                LOCATION_CENTER = new LatLng(latitude, longitude);
                // Toast.makeText(MainActivity.this, "latitude: " + latitude + " - longitude" + longitude, Toast.LENGTH_LONG).show();
            }
        }
        if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.CAMERA)) {
