Android : error when copying asset sqlite database to database director

Question

I want to use a pre fill database in my app so I found this code.

DB_NAME = "urg1718.sqlite"

public SQLiteDatabase openDatabase() {
    File dbFile = context.getDatabasePath(DB_NAME);
    String path = dbFile.getAbsolutePath();
    Log.i("path", "openDatabase: " + path);

    if (!dbFile.exists()) {
        try {
            //the file doesn't exist yet so this function is called
            copyDatabase(dbFile);
        } catch (IOException e) {
            throw new RuntimeException("Error creating source database", e);
        }
    }
    //check if the database is present in the folder
    Log.i("database", "openDatabase: " + dbFile.exists());

    return SQLiteDatabase.openDatabase(dbFile.getPath(), null, SQLiteDatabase.OPEN_READONLY);
}

private void copyDatabase(File dbFile) throws IOException {
    //pre fil database
    InputStream is = context.getAssets().open(DB_NAME);
    try {
        //where the error occurs
        OutputStream os = new FileOutputStream(dbFile);

        byte[] buffer = new byte[1024];
        while (is.read(buffer) > 0) {
            os.write(buffer);
        }

        os.flush();
        os.close();
        is.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();;
    } catch (IOException e) {
        e.printStackTrace();
    }

}

The "OutputStream os = new FileOutputStream" catch the following error.

I tried to use

getDatabasePath(), getDatabasePath().getAbsolutePath()

and directly put the string returned by those functions into

FileOutputStream

I also tried to remove the ".sqlite" from the database name.

I don't understand what i'm doing wrong ...

Thank's.
