Facebook ShareDialog cause =＆gt;发送失败结果ResultInfo {who = null ...}

Question

它工作正常，但是当我点击任何地方而不是对话框以便取消时，另一个对话显示让我选择保留为草稿或丢弃。 见下面的图片..！

如果我选择 discard =＆gt;它崩溃了..！？

我在这里https://developers.facebook.com/docs/sharing/android

应用了同样的东西

但这是代码：

@Override
  protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // this line is for facebook and it's causing the crash 
       callbackManager.onActivityResult(requestCode, resultCode, data);


 // the ones below are for photoPicker and camera
    if (resultCode == RESULT_OK) {

      if (data != null) {

        Log.i("onActivityResult: ", data.toString() + "");

        final File file = new File(data.getData().getPath());

        if (file.exists()) {

          Bitmap myBitmap = BitmapFactory.decodeFile(file.getAbsolutePath());

          BSheetPost(myBitmap);
        }

        Toast.makeText(
            this,
            String.format("Saved to: %s, size: %s", file.getAbsolutePath(), fileSize(file)),
            Toast.LENGTH_LONG)
            .show();


      }
    } else if (requestCode == PickConfig.PICK_PHOTO_DATA) {

      if (data != null) {
        ArrayList<String> selectPaths = (ArrayList<String>) data
            .getSerializableExtra(PickConfig.INTENT_IMG_LIST_SELECT);

        Bitmap bitmap = BitmapFactory.decodeFile(selectPaths.get(0));

        BSheetPost(bitmap);
      }


    } else if (data != null) {

      Exception e = (Exception) data.getSerializableExtra(MaterialCamera.ERROR_EXTRA);
      if (e != null) {
        e.printStackTrace();
        Toast.makeText(this, "Error: " + e.getMessage(), Toast.LENGTH_LONG).show();
      }
    }

  }

logcat的
