sql - Android multiple databases open -

-

i making im client android , working databases storing contacts , other info's... in app have activity , 1 service. need open 3 databases in same time both on service , on activity.

i use 3 database because want databases managed more without having problems synchronization of writing in them. (as far know need write in database synchronously because may crush).

to manage databases service , activity in same time, thought singleton or static class of databasehelper me...

so have started make test making 2 databasehelper global objects in activity, each 1 opens diferent database, after running project i've noticed last opened database remains opened in both objects :((, why happening?

can sugest me how can make work? thank you!

l.e.: after more tests, made static object of databasehelper, open service take database object activity , in same time made 2 statements, 1 in activity , 1 in service run 0 3000 , adds values same database , reads database.

after run noticed database still in feet , running without errors. strange thing service running after activity finishes job. why that? thank you!

i have databaseadapter class contains 2 databases opened together.

public class databaseadapter {     /** identifier internal database */     public static final int             internal            = 0;     /** identifier external database */     public static final int             external                = 1;      private final sqliteopenhelper[]    mdatabasemanager    = new sqliteopenhelper[2];     private final sqlitedatabase[]      mdatabases          = new sqlitedatabase[2];      /**      * constructs database , open it.      */     public databaseadapter() {         // open internal_db         mdatabasemanager[internal] = new internaldatabasemanager(myapplication.getinstance());         mdatabases[internal] = mdatabasemanager[internal].getwritabledatabase();     }      /**      * checks database state , throws {@link illegalstateexception} if database isn't open.      * should used before starting access database.      *       * @param type type of database. can internal or external.      */     public void checkdbstate(int type) {         if (mdatabases[type] == null || !mdatabases[type].isopen()) {             throw new illegalstateexception("the database has not been opened");         }     }      /**      * closes database of given type.      *       * @param type type of database. can internal or external.      */     public void close(int type) {         if (mdatabases[type].isopen()) {             mdatabases[type].close();             mdatabases[type] = null;             if (mdatabasemanager[type] != null) {                 mdatabasemanager[type].close();                 mdatabasemanager[type] = null;             }         }     }      /**      * @param type type of database. can internal or external.      * @return true if database open, false otherwise.      */     public boolean isopen(int type) {         return mdatabases[type] != null && mdatabases[type].isopen();     }      /**      * opens default database.      *       * @param type type of database. can internal or external.      */     public void open(int type) {         switch (type) {             case internal:                 mdatabasemanager[internal] = new internaldatabasemanager(myapplication.getinstance());                 if (!isopen(internal)) {                     mdatabases[internal] = mdatabasemanager[internal].getwritabledatabase();                 }             break;             case external:                 mdatabasemanager[external] = new externaldatabasemanager(myapplication.getinstance(), constants.external_db_path, 1);                 if (!isopen(external)) {                     mdatabases[external] = mdatabasemanager[external].getwritabledatabase();                 }             break;         }     } }

cocoa - Nesting arrays into NSDictionary object (Objective-C) -

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
