我根据他们的文档
实现了android登录问题是,在用户输入其凭据(1个对话框)进行登录并确认应用程序权限(2对话框)之后,facebook连接只返回到(1对话框),再次请求凭据。为什么会这样?
在Facebook用户中,我可以在应用列表中看到该应用
这是我的代码:
CallbackManager callbackManager = CallbackManager.Factory.create();
LoginButton loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions("public_profile","user_friends");
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
Log.i(Utils.TAG,"succesfull login to facebook");
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.i("LoginActivity", response.toString());
try {
}catch (Exception e)
{ Log.i(Utils.TAG, e.getMessage());
}
}
});
}
@Override
public void onCancel() {
// App code
Log.i(Utils.TAG,"onCancel login to facebook");
}
@Override
public void onError(FacebookException exception) {
// App code
Log.i(Utils.TAG,"onError login to facebook");
Log.i(Utils.TAG,exception.getMessage());
}
});
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// LoginManager.getInstance().logInWithReadPermissions((Activity)m_context, Arrays.asList("public_profile", "email", "user_birthday", "user_friends"));
LoginManager.getInstance().logInWithReadPermissions((Activity)m_context, Arrays.asList("public_profile", "user_friends"));
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.i(Utils.TAG,"onActivityResult called");
super.onActivityResult(requestCode, resultCode, data);
callbackManager.onActivityResult(requestCode, resultCode, data);
}
我应该提一下,只有当我关闭对话框时才会在登录流程中调用回调

是的,这是因为您正在使用登录按钮和登录管理器。您只需从中选择一个..因为它们都具有相同的功能。我建议你从这里删除登录管理器代码。
loginButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// LoginManager.getInstance().logInWithReadPermissions((Activity)m_context, Arrays.asList("public_profile", "email", "user_birthday", "user_friends"));
LoginManager.getInstance().logInWithReadPermissions((Activity)m_context, Arrays.asList("public_profile", "user_friends"));
}
});
和
oginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
Log.i(Utils.TAG,"succesfull login to facebook");
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.i("LoginActivity", response.toString());
try {
}catch (Exception e)
{ Log.i(Utils.TAG, e.getMessage());
}
}
});
}
@Override
public void onCancel() {
// App code
Log.i(Utils.TAG,"onCancel login to facebook");
}
@Override
public void onError(FacebookException exception) {
// App code
Log.i(Utils.TAG,"onError login to facebook");
Log.i(Utils.TAG,exception.getMessage());
}
});

那是因为facebook登录api使用chrome浏览器。登录一次后,Chrome浏览器会保留该信息。如果您在Chrome浏览器中注销Facebook,则可能会出现“1对话框”。
