try it once.

 public void ShareDialog() {
    Toast.makeText(Complete_Run_Activity.this, "Sharing to Facebook", Toast.LENGTH_SHORT).show();

    if (shareDialog.canShow(SharePhotoContent.class)) {

        SharePhoto photo = new SharePhoto.Builder()
                .setBitmap(bitmap)
                .setCaption("Hey... \nI earned by money by running/walking for the charity.")
                .build();
        SharePhotoContent content = new SharePhotoContent.Builder()
                .addPhoto(photo)
                .build();
        shareDialog.show(content);
        dialog1.dismiss();
    }
}

also

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    try {
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }catch(Exception e){
        e.printStackTrace();
    }}

and in oncreate method

 FacebookSdk.sdkInitialize(getApplicationContext());
    callbackManager = CallbackManager.Factory.create();
    shareDialog = new ShareDialog(this);
    shareDialog.registerCallback(callbackManager, new FacebookCallback<Sharer.Result>() {
        @Override
        public void onSuccess(Sharer.Result result) {
            Log.e("RESSULT", "Success");
         //   getAndAddSlots();

        }

        @Override
        public void onCancel() {

        }

        @Override
        public void onError(FacebookException error) {
            Log.e("RESSULT", "error=" + error.toString());
            Toast.makeText(Complete_Run_Activity.this, "Unable to Share Image to Facebook.", Toast.LENGTH_SHORT).show();
        }
    });
