Android Realm issue with setDefaultConfiguration -


i've got problem realm , method setdefaultconfiguration. indeed, app multi user, , need switch between several realm configurations.

during main activity loading, configure realm configuration this:

string bddname = string.format("%s.realm",userid);             userfolder = new file(getapplicationcontext().getfilesdir() + "/" + userid);             config = new realmconfiguration.builder(userfolder)                 .name(bddname)                 .schemaversion(2)                 .migration(new realmmigration2())                 .build();             realm.setdefaultconfiguration(config);

but, if try configure twice same config, realm send me error:

configurations cannot different if used open same file.

is possible test whether current configuration different 1 want set? i've tried :

if(!config.equals(realm.getdefaultinstance().getconfiguration()))

but @ first launch of activity, realm return error, because no default instance set.

i'm turning around because it's impossible test realm configuration before setting it. me ? thank lot.

edit : solution doesn't work too, i've got same error, however, realmfilename different:

try{ //first time, realm not configure, it's catched. //else, set default config if config different if(!config.getrealmfilename().equals(realm.getdefaultinstance().getconfiguration().getrealmfilename())){                     realm.setdefaultconfiguration(config);                 }             }             catch (exception e){                 realm.setdefaultconfiguration(config);             }

the problem creating 2 instances of realmmigration2 class. if don't override equals in class:

realmmigration migration1 = new realmmigration2(); realmmigration migration2 = new realmmigration2();  migration1.equals(migration2) == false

which cause comparison of realmconfigurations fail.

so should either make realmmigration instance singleton or override hashcode()/equals().
