将照片发布到Facebook权限Android SDK

Question

i am trying to publish a photo to facebook for android SDK i do not want to keep the user logged in all i want when user click of share it ask for login (if not logged in) and publish a photo to facebook wall

here is the code i write but it gives an error

an attempt was made to request new permissions for a session that has pending request

Code:

Session session = new Session(this);
    Session.setActiveSession(session);

    session.openForPublish(new Session.OpenRequest(this)
    .setCallback(null).setPermissions(permissions));

    Session.NewPermissionsRequest newPermissionsRequest = 
            new Session.NewPermissionsRequest(this, Arrays.asList("publish_actions"))
    .setRequestCode(100);

    Session.openActiveSession(this, true, null)
        .requestNewPublishPermissions(newPermissionsRequest);




    Drawable d = getResources().getDrawable(R.drawable.s0);

    Bitmap bmap = Bitmap.createBitmap(d.getIntrinsicWidth(), d.getIntrinsicHeight(), Config.ARGB_8888);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();

    bmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);

    byte[] byteArray = stream.toByteArray();

    Bundle params = new Bundle();

    params.putByteArray("picture", byteArray);
    params.putString("message", "");

    Request request = new Request(Session.getActiveSession(), "me/photos",params, 
             HttpMethod.POST);

    request.setCallback(new Request.Callback() {

        @Override
        public void onCompleted(Response response) {
            if (response.getError()==null) {
                Toast.makeText(getApplicationContext(), "Successfully posted photo", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getApplicationContext(), response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
            }

        }
    });
    request.executeAsync();
