android - Unbinding drawables from view on onDestroy() -

-

I've read a lot about memory leaks in the last few days, and came in some interesting stuff. I saw a basic Android bitmap memory leak question (since 2011) and I was thinking that this is still the case. If I am using scenes that contain bitmaps in my activity (image view, text view ...), do I need to break my own designs to destroy the activity? Is it only in some cases or always?

It is no longer required as 4.0 because callback is now a WeakReference .

: Public Final Zero Set Callback (Callback CB) {mCallback = cb; }

and: 

  public final zero set callback (callback CB) {mCallback = new WeakReference & lt; Callback & gt; (CB); }

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...
