私はこの URL http://translate.google.com/translate_tts?ie=UTF-8&q=hi&tl=en&total=1&idx=0&textlen=2を持っています

それをPCとAndroidブラウザに配置すると、ブラウザなしでAndroidアプリケーションにダウンロードする方法を強制的にダウンロードするようになります。このチュートリアルを使用してダウンロードしようとしましたが、URL でサーバーからオーディオ ファイルをダウンロードするにはどうすればよいですか 。しかし、うまくいきませんでした。誰でも助けてください

Kristijana Draca さんありがとうございます

AsyncTask を使用して任意のファイルをダウンロードできます。

downloadContent();

private void downloadContent() {
        DownloadFile downloadFile = new DownloadFile();
        downloadFile.execute("http://somehost.com/file.mp3");
}

// usually, subclasses of AsyncTask are declared inside the activity class.
// that way, you can easily modify the UI thread from here
private class DownloadFile extends AsyncTask<String, Integer, String> {
    @Override
    protected String doInBackground(String... sUrl) {
        try {
            URL url = new URL(sUrl[0]);
            URLConnection connection = url.openConnection();
            connection.connect();

            int fileLength = connection.getContentLength();

            InputStream input = new BufferedInputStream(
                    connection.getInputStream());
            // Create db
            OutputStream output = new FileOutputStream(
                    Environment.getDataDirectory() + "/data/"
                            + PACKAGE_NAME + "/file.mp3");

            byte data[] = new byte[1024];
            long total = 0;
            int count;
            while ((count = input.read(data)) != -1) {
                total += count;
                // publishing the progress....
                publishProgress((int) (total * 100 / fileLength));
                output.write(data, 0, count);
            }

            output.flush();
            output.close();
            input.close();

        } catch (Exception e) {
        }
        return null;
    }

    @Override
