how move realm file in sd card?

and not move, connect application?

realm has constructors opening file: http://realm.io/docs/java/0.80.0/api/io/realm/realm.html#getinstance-java.io.file-java.lang.string-

so should work:

realm realm = realm.getinstance(environment.getexternalstoragedirectory()); 

and remember add manifest:

<manifest ...>     <uses-permission android:name="android.permission.write_external_storage" />     <uses-permission android:name="android.permission.read_external_storage" />     ... </manifest> 

also not phones has sd card , might not mounted need additional checks if don't want encounter lots of weird crashes in production: http://developer.android.com/guide/topics/data/data-storage.html#filesexternal
