对此感到生气。我尝试登录FB并同时检索用户信息。
FB登录正常,应用程序更改为FB,显示应用程序要求的权限,按“接受”后,返回到我的应用程序。但是从不调用registerCallback。我的错误在哪里?在这里我的代码:
FacebookSdk.sdkInitialize(getApplicationContext());
CallbackManager mCallbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().logInWithReadPermissions(
this,
permissionNeeds);
LoginManager.getInstance().registerCallback(mCallbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.e("dd", "SUCCESS");
GraphRequest.newMeRequest( loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject json, GraphResponse response) {
if (response.getError() != null) {
System.out.println("ERROR");
} else {
System.out.println("Success");
try {
String jsonresult = String.valueOf(json);
System.out.println("JSON Result" + jsonresult);
String str_email = json.getString("email");
String str_id = json.getString("id");
String str_firstname = json.getString("first_name");
String str_lastname = json.getString("last_name");
} catch (JSONException e) {
e.printStackTrace();
}
}
}
}).executeAsync();
}
@Override
public void onCancel() {
Log.e("dd", "facebook login canceled");
}
@Override
public void onError(FacebookException e) {
Log.e("dd", "facebook login failed error");
}
});
答案 0 :(得分:5)
编辑:
发现它,以下代码丢失,现在我在登录后获取用户信息
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
