    Realm.deleteRealmFile(instance);
}

Answer 1

Update

Use realm.delete(Foo.class) instead as clear() is deprecated. From 0.91.0 all @Deprecated methods will be removed.

Christian from Realm here. That approach will work as long as you have closed all open Realm instances. Another approach is clearing the tables you want like this:

realm = Realm.getInstance(getApplicationContext());

public void clearDB() {
  realm.executeTransaction(new Realm.Transaction() {
     @Override
     public void execute(Realm realm) {
        realm.clear(Foo.class);
        realm.clear(Bar.class);
     }
  });
}

You can read more here: http://realm.io/docs/java/0.77.0/api/io/realm/Realm.html#clear(java.lang.Class)

Answer 2

use realm.delete(Myclass.class);

realm = Realm.getDefaultInstance();

    realm.beginTransaction();
    realm.delete(SuggestedAppDto.class);
    realm.delete(WifiSpotsDto.class);
    realm.commitTransaction();
    realm.close();

this worked for me.
