我有一个LoginViaFacebook活动和一个用于facebook登录的登录按钮。我使用以下代码登录到facebook
private String[] permissions = {"publish_stream",
"read_stream", "user_photos", "publish_checkins", "photo_upload",
"email", "user_birthday" };
if (access_token != null) {
Utility.fb.setAccessToken(access_token);
token = access_token;
Log.e("OnCretae Facebook Token------------", token);
}
if (expires != 0) {
Utility.fb.setAccessExpires(expires);
}
btn_login.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
if (CheckInternet.checkConn(LoginViaFacebook.this)) {
Utility.fb.authorize(LoginViaFacebook.this, permissions,
new DialogListener() {
@Override
public void onFacebookError(FacebookError e) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"onFacebookError",
Toast.LENGTH_LONG).show();
Log.e("Sajolllllllllllllllll", e + "");
}
@Override
public void onError(DialogError e) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"onError", Toast.LENGTH_LONG)
.show();
Log.e("Sajolllllllllllllllll", e + "");
}
@Override
public void onComplete(Bundle values) {
// TODO Auto-generated method stub
editor = sp.edit();
token = Utility.fb.getAccessToken();
Log.e("Token---------", token);
editor.putString("access_token",
Utility.fb.getAccessToken());
editor.putLong("access_expires",
Utility.fb.getAccessExpires());
editor.commit();
Toast.makeText(getApplicationContext(),
"Login Successful",
Toast.LENGTH_LONG).show();
mProgress = ProgressDialog.show(
LoginViaFacebook.this, "",
"Please Wait...", true);
Thread t = new Thread(retriveProfileData);
t.start();
}
@Override
public void onCancel() {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"onCancel", Toast.LENGTH_LONG)
.show();
}
});
}
}
});
如果用户没有注销，我会保存访问令牌以便下次直接登录
我有另一个活动，即设置和按钮注销。我使用以下代码从facebook 注销
lagoutLayout.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
final String[] items = new String[] { "Yes", "No" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
SettingsActivity.this,
android.R.layout.select_dialog_item, items);
AlertDialog.Builder builder = new AlertDialog.Builder(
SettingsActivity.this);
builder.setTitle("Select Option");
builder.setAdapter(adapter,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) { // pick
// from
// camera
if (item == 0) {
try {
editor.remove("FacebookId");
editor.remove("EmailId");
editor.commit();
Log.e("Pre----------------", sp1
.getString("access_token", "d"));
editor1.remove("access_token");
editor1.remove("access_expires");
editor1.commit();
Log.e("After----------------", sp1
.getString("access_token", "d"));
Log.e("DATATTAT--------",
sp.getString("FacebookId",
"saf")
+ " "
+ sp.getString(
"EmailId", "as"));
String r = Utility.fb
.logout(SettingsActivity.this);
Log.e("Res-----------", r);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else { // pick from file
dialog.dismiss();
}
}
});
dialog = builder.create();
dialog.show();
}
});
Facebook注销方法的响应在日志中显示为true。但当我再次运行应用程序时，它会自动登录到facebook我找不出问题。请帮助我
我使用了这个代码，它在中运行得很好
public void logout() {
if (!isConnected(activity)) {
Toast.makeText(activity, "Internet not connected", Toast.LENGTH_LONG).show();
return;
}
SessionEvents.onLogoutBegin();
AsyncFacebookRunner asyncRunner = new AsyncFacebookRunner(this.facebook);
asyncRunner.logout(this.context, new LogoutRequestListener());
}
这是听众
public class LogoutRequestListener extends BaseRequestListener {
public void onComplete(String response, final Object state) {
// callback should be run in the original thread,
// not the background thread
mHandler.post(new Runnable() {
public void run() {
SessionEvents.onLogoutFinish();
Intent intent= new Intent(activity,Login.class);
activity.startActivity(intent);
activity.finish();
}
});
}
}
对于以上的facebooksdk版本3
public void logoutFacebook() {
Session session = Session.getActiveSession();
if(session != null && session.isOpened()){
session.closeAndClearTokenInformation();
}
}
如果你在登录时扩展并使用facebookopenSession，你必须使用closeSession关闭它并将其放入注销，或者你可以像这个一样简单地将其置于Destroy
public void onDestroy() {
this.closeSession();
super.onDestroy();
}
试试这个：
我希望这对你有帮助。。。
if (mFacebook.isSessionValid()) {
try {
String str = mFacebook.logout(getApplicationContext());
SessionStore.clear(getApplicationContext());
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
如果您正在查看谷歌建议中的答案，并使用facebooksdk v4或更高版本，请使用以下行。它工作得很好。
if (AccessToken.getCurrentAccessToken() != null) {
LoginManager.getInstance().logOut();
}
