Inserting in SQLite database from file, only one row inserted

I'm inserting rows in android SQLite database from a file. In the onUpdate function in the databaseHelper I call the insertInDb function:

InputStream is = null;
AssetManager assetManager = context.getResources().getAssets();
String fileLine = "";
String[] data;
ContentValues row = new ContentValues();
long rowid;

try {
    is = assetManager.open(filename);
    BufferedReader br = new BufferedReader(new InputStreamReader(is));
    db.beginTransaction();
    while((fileLine = br.readLine()) != null){
        data = fileLine.split("@-@");
        row.put(QuoteAllEntry.COLUMN_QUOTE, data[0]);
        row.put(QuoteAllEntry.COLUMN_AUTHOR, data[1]);
        row.put(QuoteAllEntry.COLUMN_FAVORITE, 0);
        row.put(QuoteAllEntry.COLUMN_CAT_KEY, data[2]));
        rowid = db.insert(DataContract.QuoteAllEntry.TABLE_NAME, null, row);
    }
    db.setTransactionSuccessful();
}catch (Exception e) {
    e.printStackTrace();
}
finally {
    db.endTransaction();
}

Only one row of data is inserted, and it is the last row of the file. What is going wrong? I can't seem to find the problem.
