我的应用程序已经有一个登录程序，但如果我尝试使用 FB 登录，则尝试与 facebook graph api 集成，应用程序不接受。帮助我在这里粘贴 FB 按钮代码
case R.id.fbButton:
authenticateOnFacebook();
sendFacebookIdToServer(APP_ID, getApplicationContext());
break;
facebook 的身份验证方法，在此我也使用 getcredentials 方法。
public void authenticateOnFacebook()
{
try{
String[] permissions={"user_birthday", "email"};
facebook.authorize(this.activity, permissions, Facebook.FORCE_DIALOG_AUTH, new DialogListener() {
@Override
public void onFacebookError(FacebookError e) {
}
@Override
public void onError(DialogError e) {
}
@Override
public void onComplete(Bundle values) {
try{
String facebookId = getCredentials((String) values.get("access_token"));
sendFacebookIdToServer(facebookId, context);
} catch(Exception e){
e.printStackTrace();
}
}
@Override
public void onCancel() {
}
});
} catch(Exception e){
e.printStackTrace();
}
}
protected String getCredentials(String token) {
JSONObject jObject=null;
String facebookId = null;
Bundle params = new Bundle();
params.putString(Facebook.TOKEN, token);
try {
jObject = new JSONObject(facebook.request("me", params));
}catch(Exception e){
e.printStackTrace();
}
if(jObject!=null)
{
try {
facebookId = jObject.getString("id");
}catch(Exception e){
e.printStackTrace();
}
}
return facebookId;
}
为了向我的服务器发送请求以进行身份验证，我正在使用这种方法
public void sendFacebookIdToServer(String facebookId, Context context){
String accessToken = null;
DatabaseHelper helper = new DatabaseHelper(context);
DatabaseUtility dao = new DatabaseUtility(helper);
try {
accessToken = dao.getAccessToken();
} catch (Exception e1) {
e1.printStackTrace();
}
Map<String , String> params = new HashMap<String,String>();
params.put(Constants.FACEBOOK_ID, facebookId);
params.put(Constants.ACCESS_TOKEN_PARAM, accessToken);
Status status = null;
try {
status = Utils.addFacebookAccount(params, context);
} catch (NullPointerException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
if((status != null) && (status.getStatus().equalsIgnoreCase(Constants.SUCCESS))){
navigateNowLisnScreenWithSuccess();
}
}
private void navigateNowLisnScreenWithSuccess() {
// TODO Auto-generated method stub
Intent i = new Intent(context,TabView.class);
startActivity(i);
}
