我有以下代码登录Facebook并获取用户的电子邮件，这在用户没有安装本机应用程序时工作正常，它会打开弹出窗口并让用户输入他们的Facebook信息。 但是，当他们有本机应用程序时，它会要求权限，而不会做任何事情。 似乎我遇到与How to disable facebook native app for user login以及Android Facebook authorization - can not log in when official Facebook app is installed
相同的问题但是我的代码有点不同所以我希望有人可以帮助我强制我的代码只使用弹出窗口。
我的代码
public class FbLoginActivity extends Activity {
private static List<String> permissions;
Session.StatusCallback statusCallback = new SessionStatusCallback();
ProgressDialog dialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fblogin);
Button fbButton = (Button) findViewById(R.id.fbshare);
/***** FB Permissions *****/
permissions = new ArrayList<String>();
permissions.add("email");
/***** End FB Permissions *****/
fbButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Check if there is any Active Session, otherwise Open New
// Session
Session session = Session.getActiveSession();
if (session == null) {
Session.openActiveSession(FbLoginActivity.this, true,
statusCallback);
} else if (!session.isOpened()) {
session.openForRead(new Session.OpenRequest(
FbLoginActivity.this).setCallback(statusCallback)
.setPermissions(permissions));
}
}
});
Session session = Session.getActiveSession();
if (session == null) {
if (savedInstanceState != null) {
session = Session.restoreSession(this, null, statusCallback,
savedInstanceState);
}
if (session == null) {
session = new Session(this);
}
Session.setActiveSession(session);
session.addCallback(statusCallback);
if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
session.openForRead(new Session.OpenRequest(this).setCallback(
statusCallback).setPermissions(permissions));
}
}
}
private class SessionStatusCallback implements Session.StatusCallback {
@Override
public void call(Session session, SessionState state,
Exception exception) {
// Check if Session is Opened or not
processSessionStatus(session, state, exception);
}
}
public void processSessionStatus(Session session, SessionState state,
Exception exception) {
if (session != null && session.isOpened()) {
if (session.getPermissions().contains("email")) {
// Show Progress Dialog
dialog = new ProgressDialog(FbLoginActivity.this);
dialog.setMessage("Logging in..");
dialog.show();
Request.executeMeRequestAsync(session,
new Request.GraphUserCallback() {
@Override
public void onCompleted(GraphUser user,
Response response) {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
}
if (user != null) {
Map<String, Object> responseMap = new HashMap<String, Object>();
GraphObject graphObject = response
.getGraphObject();
responseMap = graphObject.asMap();
Log.i("FbLogin", "Response Map KeySet - "
+ responseMap.keySet());
// TODO : Get Email
// responseMap.get("email");
String fb_id = user.getId();
String email = null;
String name = (String) responseMap
.get("name");
if (responseMap.get("email") != null) {
email = responseMap.get("email")
.toString();
Intent i = new Intent(FbLoginActivity.this, FbLogin2Activity.class);
i.putExtra("Email", email);
startActivity(i);
} else {
// Clear all session info & ask user to
// login again
Session session = Session
.getActiveSession();
if (session != null) {
session.closeAndClearTokenInformation();
}
}
}
}
});
} else {
session.requestNewReadPermissions(new Session.NewPermissionsRequest(
FbLoginActivity.this, permissions));
}
}
}
/********** Activity Methods **********/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("FbLogin", "Result Code is - " + resultCode + "");
Session.getActiveSession().onActivityResult(FbLoginActivity.this,
requestCode, resultCode, data);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Save current session
super.onSaveInstanceState(outState);
Session session = Session.getActiveSession();
Session.saveSession(session, outState);
}
@Override
protected void onStart() {
// TODO Add status callback
super.onStart();
Session.getActiveSession().addCallback(statusCallback);
}
@Override
protected void onStop() {
// TODO Remove callback
super.onStop();
Session.getActiveSession().removeCallback(statusCallback);
}
更新 所以我没有在Facebook开发设置中设置活动，这是有意义的，所以我应该把它作为活动，以便FbLoginActivity processSessionStatus被登录触发（所以我可以获取电子邮件地址并传入）
答案 0 :(得分：1)
如果您使用facebook SDK，则这是默认行为。如果用户安装了facebook应用程序，那么它将使用该凭据，如果没有，则会显示弹出窗口。这是它的设计功能，因为用户不必在每个使用Facebook进行身份验证的应用程序中反复输入他的凭据。如果要覆盖此行为，则必须分叉并修改SDK本身。

您是否已在Facebook.com上的Facebook App设置中输入了身份验证完成后原生facebook应用程序要进行的活动的名称？
可能会丢失或出现错误，导致原生facebook应用在注册完成后调用不存在的活动。
答案 2 :(得分：0)
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
}
在您呼叫Facebook登录请求的活动中使用此代码。

答案是： 在你的cade中添加这一行
session.openForRead(new Session.OpenRequest(
FbLoginActivity.this).setCallback(statusCallback)
.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);// add this line for open only dialog or pop-up
.setPermissions(permissions));
