在Android Studio中更新预建的SQL数据库

private void copyDatabase() {
    try {
        InputStream inputStream = getApplicationContext().getAssets().open("your_database_name.db");
        String outFileName = getApplicationContext().getDatabasePath("your_database_name.db").getPath();
        OutputStream outputStream = new FileOutputStream(outFileName);
        byte[] buffer = new byte[1024];
        int length;
        while ((length = inputStream.read(buffer)) > 0) {
            outputStream.write(buffer, 0, length);
        }
        outputStream.flush();
        outputStream.close();
        inputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
