问题
I want tot send a friend request using the Facebook Android SDK. I'm currently using this code (which I got from here):
Bundle parameters = new Bundle();
parameters.putString("APP_ID","USERNAME");
facebook.dialog(this, "friends", parameters, this);
where APP_ID is the Facebook ID of my app and USERNAME is the username of the friend I want to add. This leads to the following error:
API Error Code:100
Invalid parameter
The parameter id is required
I thought the id parameter meant the APP_ID.
I have gone through the relevant documentation regarding dialogs at http://developers.facebook.com/docs/reference/dialogs/friends/ and http://developers.facebook.com/docs/reference/androidsdk/dialog/, but still can't figure it out.
Any help is appreciated.
回答1:
Should be something like:
Bundle parameters = new Bundle();
parameters.putString("id", USER_ID);
facebook.dialog(this, "friends", parameters, this);
In case that this is an activity which also implements DialogListener.
As it says in the documentation:
app_id - Your application's identifier. Required, but automatically specified by most SDKs.
id - Required. The ID or username of the target user to add as a friend.

You can use:
WebDialog.RequestsDialogBuilder requestBuilder = (new WebDialog.RequestsDialogBuilder(this,
Session.getActiveSession(), params)).setOnCompleteListener(
new OnCompleteListener() {
@Override
public void onComplete(Bundle values,
FacebookException error) {
if (error != null) {
} else {
final String requestId = values
.getString("request");
if (requestId != null) {
//if the user completed the action,
} else {
}
}
}
});
WebDialog requests = requestBuilder.build();
requests.show();
If you want to set the request to preselected friends just add the following to the requestBuilder:
requestBuilder.setTo("FRIEND_ID, ANOTHER_FRIEND_ID"), before building the dialog.
What is strange is that it accepts the list of friends as a concatenated list of ids, not an Array nor list. I didn't find in in the docs, but just found that it works
