How to copy files from Android bundle?

[NunoCardoso]

Hi.

I am bundling a sqlite3 file with my react-native app.

For iOS, I can access easily by adding the file in XCode, and then access it with RNFS.MainBundlePath (I want to copy it to the Documents area so I can write on it)

How to do this on Android?

i am also bundling sqlite-files with my rn-apps using this practice from react-native-sqlite-storage: https://github.com/andpor/react-native-sqlite-storage/#setting-up-your-project-to-import-a-pre-populated-sqlite-database-from-application-for-ios

have you tried this? works out of the box if everything was done right.

Aren't those instructions for iOS only? I want to do this for Android, my iOS version is working fine.

Got your point now. There is a small sentence stating:

"For Android, the www directory is always relative to the assets directory for the app: src/main/assets"

Putting the database into the assets directory will let you create a database copied over from the prebundled one.

template.sqlite:

    let params = { name: DATABASE_NAME + mandantId, createFromLocation: "~template.sqlite" }
    if (Platform.OS === 'ios') {
        params.location = 'Library';
    }

    return new Promise((resolve, reject) => {
        SQLite.openDatabase(params, (db) => {
            __db = db;
            __isDatabaseOpen = true;

            resolve(db)
        }, (err) => reject(err));
    })

Ok, will give a try. Still, regarding my original question, which is to copy files from the app bundle to the dedicated app's space... that is possible with iOS, but for Android, I then assume it is not be cause react-native-fs MainBundlePath doesn't return anything.

Did you solve it? Did you manage to open the database? I have a similar problem on android
