Share SQLite database from Android app, without intermediate copy -

i want allow users of android app export sqlite database file content create. current solution copies file private storage (/data/data/com.package.name/files/content.db), creates uri file , opens share dialog. working, allowing me export database file using dropbox, example. here code i'm using, partially adapted https://stackoverflow.com/a/2661882 -

private void exportcontent() {     copycontenttoprivatestorage();      intent intent = new intent(intent.action_send);     intent.settype("application/octet-stream");      uri uri = new fileprovider().getdatabaseuri(this);      intent.putextra(intent.extra_stream, uri);     intent.setflags(intent.flag_grant_read_uri_permission);      startactivity(intent.createchooser(intent, "backup via:")); }  private void copycontenttoprivatestorage() {     // https://stackoverflow.com/a/2661882     try {         file data = environment.getdatadirectory();         file sd = getfilesdir();          if (sd.canwrite()) {             string currentdbpath = "//data//com.package.name//databases//content.db";             string backupdbpath = "content.db";             file currentdb = new file(data, currentdbpath);             file backupdb = new file(sd, backupdbpath);              if (currentdb.exists()) {                 filechannel src = new fileinputstream(currentdb).getchannel();                 filechannel dst = new fileoutputstream(backupdb).getchannel();                 dst.transferfrom(src, 0, src.size());                 src.close();                 dst.close();             }         }     } catch (exception e) {         toast.maketext(this, e.tostring(), toast.length_long).show();     } }  public class fileprovider extends android.support.v4.content.fileprovider {      public uri getdatabaseuri(context c) {         file exportfile = new file(c.getfilesdir(), "content.db");         uri uri = geturiforfile(c, "com.package.name.fileprovider", exportfile);          c.granturipermission("*", uri, intent.flag_grant_read_uri_permission);          return uri;     } } 

it seems should able directly create uri existing database path, instead of doing intermediate copy. there way this?

i keep doing intermediate copy, believe bad practice leave second copy of database in data directory longer necessary. there way clean , delete after chosen app has finished using uri share file?
