我正在創建一個安卓相機應用程序,我想將它連接到Facebook。 我爲我的應用程序創建了一個頁面,並創建了一個Open Graph故事「x使用MyApp拍攝了照片」。 我正在使用OpenGraphActionDialogBuilder,但出於某種原因,我已經能夠在所創建的OpenGraphActionDialog中看到附加圖像的預覽。FacebookDialog.OpenGraphActionDialogBuilder不顯示圖像預覽
這裏是我的代碼:
public void shareWithFacebook(File imageFile) {
// get session
Session session = Session.getActiveSession();
// make sure we have publish permissions
boolean hasPublishPermissions = hasPublishPermission();
if (!hasPublishPermissions) {
if (!session.isOpened()) {
Session.OpenRequest openRequest = new Session.OpenRequest(this);
openRequest.setPermissions("user_friends");
session.openForRead(openRequest);
}
requestPublishPermissions(session);
}
ArrayList<File> files = new ArrayList<File>();
files.add(imageFile);
OpenGraphAction action = OpenGraphAction.Factory.createForPost("mycameraapp:took");
OpenGraphObject picture = OpenGraphObject.Factory.createForPost("mycameraapp:picture");
picture.setProperty("title", "");
action.setProperty("picture", picture);
FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(this, action, "picture")
.setImageAttachmentFilesForObject("picture", files, true)
.build();
if (FacebookDialog.canPresentOpenGraphActionDialog(this))
shareDialog.present();
}
