android - Confirmation login dialog does not appear in facebook api, google+ api, vk api -


my question little broad, in case had same possible. after first launch facebook, google+ , vk.com asked me confirm requested permission (for example, facebook: "public_profile, email, user_friends"). every next time confirmation dialog did not appear. cleared cache, reinstalled app, still nothing. maybe lost something? or facebook remembered device , doesn't ask confirmation second time? still have information requested, without confirmation. google+ doesn't open activity, straight away shows me result. example facebook code.

my grahrequest same in docs of facebook api , execute in onsuccess() callback added loginmanager. permissions set loginmanager aswell as: loginmanager..getinstance().loginwithreadpermissions(...).

graphrequest request = graphrequest.newmerequest(     accesstoken,     new graphrequest.graphjsonobjectcallback() {         @override         public void oncompleted(                jsonobject object,                graphresponse response) {             // code         }     }); request.executeasync();

any explanation appreciated, thanks.

once user accepts permissions app, if app asks same permissions same user, no re-confirmation needed. time confirmation needed if ask more permissions, or if user has de-authorized app https://www.facebook.com/settings?tab=applications.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
