handle = nativeCreate(canonicalPath, builder.maxSizeInKByte, builder.maxReaders, builder.model);

Possibly try the solution suggested in this comment in #370. -ut

[lohago10]

it doesn't work @greenrobot-team

[lohago10]

is this your logcat "E/Box: Storage error code -30793"?

[greenrobot]

Where did you get the file "data.db" from?

[lohago10]

it belongs to my company ,I can read it by Navicat Premium ,I put it in app's assets @greenrobot

[lohago10]

By the way,I need to query one data in about 230000 rows ,could you give me some advice on which database to choose, greendao or sqlite？ @greenrobot

[greenrobot]

You can read only database files created by ObjectBox. I do not think that Navicat can read ObjectBox DBs yet, so I would guess you are trying to feed ObjectBox with an alien DB.

Having 230,000 objects is not a challenge. It rather depends on how complex the query is.

[lohago10]

So I can't read an alien DB like greendao does? I changed to use sqlite in the end. I don't like sql and I'm looking forward to ObjectBox's more functions.

[greenrobot]

No, SQLite DBs cannot be read. We might provide a tool that helps migrating at some point.
