android - When I set the ringermode to RINGER_MODE_SILENT, the phone still vibrates and the icon in the menu is set to the 'vibrate' icon -

-

जब मैं इस कोड को निष्पादित करता हूं: 

  mAudioManager.setRingerMode (AudioManager.RINGER_MODE_SILENT);

शीर्ष पर मेरे मेनूबार में आइकन को कंपन आइकन पर सेट किया गया है और कंपन सेटिंग को कंपन करने के लिए सेट किया गया है और चुप नहीं है।

क्या मैं 'मौन से अपेक्षा करता हूं 'ना-कंपन, नो-ध्वनि है।

यह एंड्रॉइड 4.4.4 पर मेरे फोन पर है

इसे आज़माएं:

<पूर्व> ऑडियो मैनेजर ऑडियो = (ऑडियो मैनेजर) getSystemService (संदर्भ। AUDIO_SERVICE); audio.setRingerMode (0);

एंड्रॉइड मेनिफेस्ट फ़ाइल: 

  & lt; आवेदन & gt; & Lt; उपयोग-अनुमति एंड्रॉइड: name = "android.permission.WRITE_SETTINGS" / & gt; & Lt; उपयोग-अनुमति एंड्रॉइड: name = "android.permission.WRITE_SECURE_SETTINGS" / & gt; & Lt; उपयोग-अनुमति एंड्रॉइड: name = "android.permission.MODIFY_AUDIO_SETTINGS" / & gt; & Lt; / आवेदन & gt;

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
