Question

我的应用程序检查是否有更新的版本要使用。此过程在版本2中运行良好，但版本4.1无效。

private class ExecuteUpdate implements Runnable {
    @Override
    public void run() {
        try {
            updateIntent = Updater.executeUpdate(updateHandler);

            updateHandler.sendEmptyMessage(0);
        } catch (IOException e) {
            Message msg = new Message();
            msg.obj = e;

            updateHandler.sendMessage(msg);
        }
    }
}

public static Intent executeUpdate(Handler updateHandler) throws IOException {
    URL url = new URL(Application.getInstance().getURL()
            + "/Prisma3Mobile/Prisma3Mobile.apk");
    HttpURLConnection urlConnection = (HttpURLConnection) url
            .openConnection();
    urlConnection.setRequestMethod("GET");
    urlConnection.setDoOutput(true);
    urlConnection.connect();

    File sdcard = Environment.getExternalStorageDirectory();
    File file = new File(sdcard, "Prisma3Mobile.apk");

    FileOutputStream fileOutput = new FileOutputStream(file);
    InputStream inputStream = urlConnection.getInputStream();

    byte[] buffer = new byte[1024];
    int bufferLength = 0;
    int contentLength = urlConnection.getContentLength();

    // Determina valor máximo do ProgressDialog
    Message msg = new Message();
    msg.obj = contentLength;
    updateHandler.sendMessage(msg);

    while ((bufferLength = inputStream.read(buffer)) > 0) {

        // Atualiza ProgressDialog
        msg = new Message();
        msg.obj = file.length();            
        updateHandler.sendMessage(msg);

        fileOutput.write(buffer, 0, bufferLength); 
    }

    fileOutput.close();

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(
            Uri.fromFile(new File(Environment.getExternalStorageDirectory()
                    + "/Prisma3Mobile.apk")),
            "application/vnd.android.package-archive");

    return intent;
}
