我在ecllipe中导入了最新的facebook sdk。当我试图在我的应用程序中获取基本信息时,它不会导入各自的Request,Response和Session包。我会做什么?导入相应的包。 我尝试了下面的代码,但在导入相应的软件包时面临问题。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (Session.getActiveSession() == null
|| Session.getActiveSession().isClosed()) {
Session.openActiveSession(this, true, new StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
System.out.println("State= " + state);
if (session.isOpened()) {
System.out.println("Token=" + session.getAccessToken());
Request.executeMeRequestAsync(session,
new GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (user != null) {
System.out.println("User=" + user);
}
if (response != null) {
System.out.println("Response="
+ response);
Toast.makeText(MainActivity.this,
response.toString(),
Toast.LENGTH_LONG).show();
}
}
});
}
if (exception != null) {
System.out.println("Some thing bad happened!");
exception.printStackTrace();
}
}
});
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode,
resultCode, data);
}
答案 0 :(得分:3)
它发生在您身上,因为会话已从新的Android SDK 4中删除。因此您无法使用此代码获取用户信息。
尝试使用此代码。这对我来说很成功。
首先在onCreate中初始化FacebookSdk,然后再选择布局。
FacebookSdk.sdkInitialize(this.getApplicationContext());
loginButton = (LoginButton) findViewById(R.id.login_button);
List < String > permissionNeeds = Arrays.asList("user_photos", "email",
"user_birthday", "public_profile", "AccessToken");
loginButton.registerCallback(callbackManager,
new FacebookCallback < LoginResult > () {@Override
public void onSuccess(LoginResult loginResult) {
System.out.println("onSuccess");
String accessToken = loginResult.getAccessToken()
.getToken();
Log.i("accessToken", accessToken);
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {@Override
public void onCompleted(JSONObject object,
GraphResponse response) {
Log.i("LoginActivity", response.toString());
try {
id = object.getString("id");
try {
URL profile_pic = new URL(
"http://graph.facebook.com/" + id + "/picture?type=large");
Log.i("profile_pic",
profile_pic + "");
} catch (MalformedURLException e) {
e.printStackTrace();
}
String name = object.getString("name");
String email = object.getString("email");
String gender = object.getString("gender");
String birthday = object.getString("birthday");
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields",
"id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
System.out.println("onCancel");
}
@Override
public void onError(FacebookException exception) {
System.out.println("onError");
Log.v("LoginActivity", exception.getCause().toString());
}
});
添加方法。
@Override
protected void onActivityResult(int requestCode, int responseCode,
Intent data) {
super.onActivityResult(requestCode, responseCode, data);
callbackManager.onActivityResult(requestCode, responseCode, data);
}
