I am doing database syn. Downloading data between sql server and sqlite.If there some circumstance while updating/inserting records in sqlite ,internet connectivity is slow or drop then need to roll back.Is it possible in this code or How to use Transaction here.

 public void insertTableRecords(String strTableName, String[] strToFields, String[] strValues){
    DBAdapter dbAdapter = DBAdapter.getDBAdapterInstance(DownlaodTableActivity.this);
    dbAdapter.openDataBase();
    ContentValues initialValues = new ContentValues();
    for(int i=0 ;i<strToFields.length;i++){
        initialValues.put(strToFields[i],strValues[i]);
    }
    long n = dbAdapter.insertRecordsInDB(strTableName, null, initialValues);
    System.out.println( " -- inserted status : --- " + n);
}
