Realm Java prepackaged database

I am trying to put a preloaded Realm database in my app.

What I am doing:

  1. I created a simple app that loads data from JSON to the Realm database (default1.realm).

  2. I have my actual app, where I am trying to put the default.realm file created by the loader in the res/raw folder and using the Migration Examples copyBundledRealmFile() function to copy default.realm to getFilesDir().

  3. After doing all this, when I try to do Realm.getInstance() then an empty Realm is returned.

What am I doing wrong?

String path3 = copyBundledRealmFile(this.getResources().openRawResource(R.raw.default1), "default.realm");

Realm r1 = Realm.getInstance(this);

r1 should point to the file I copied, right?

UPDATE: I found why I could not access the database:

03-27 10:27:50.965  17750-17750/? A/art﹕ art/runtime/check_jni.cc:65] JNI DETECTED ERROR IN APPLICATION: 
input is not valid Modified UTF-8: illegal continuation byte 0x2e
03-27 10:27:50.965  17750-17750/? A/art﹕ art/runtime/check_jni.cc:65]     string: 'Unspecified exception. 
Failure when converting long string to UTF-16 error_code = 2; retcode = 0; StringData.size = 40487; StringData.data = etc..

My question would be now why is this error happening?

You say that your file is named default.realm and yet you refer to it as default1 in the snippet above. Does it work if you try with default?
