次のコードを使用して、Android アプリケーションを介してビデオをアップロードしたいと考えています。

HttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(uri);
MultipartEntity entity = new MultipartEntity();
ContentBody input = new FileBody(file);
ContentBody name  = new StringBody("VID_20130201_162220.3gp");
ContentBody description = new StringBody("Test Description");
entity.addPart("input",input);
entity.addPart("name",name);
entity.addPart("description",description);
httpPost.setEntity(entity);
HttpResponse response = httpClient.execute(httpPost);
HttpEntity httpEntity = response.getEntity();

httpClient.execute() メソッドが応答を返すと、「HTTP/1.1 415 Unsupported Media Type」と表示されます

MultipartEntry を HttpPost から削除しようとしましたが、それでも同じエラーが発生します。

誰かが私に何が問題なのか教えてもらえますか?

この解決策を試してください。ほとんどの種類のファイルで機能します。

    mHttpClient = new DefaultHttpClient(params);
}

        multipartEntity.addPart("Image", new FileBody(file));
        httppost.setEntity(multipartEntity);
        mHttpClient.execute(httppost, new PhotoUploadResponseHandler());
    }

3gp メディア タイプを許可するようにサーバーに指示する必要があります。Apache を使用している場合はAddType video/3gpp .3gp、サーバーの構成ファイルに追加することでこれを行うことができます。（それが正しい構文だと思います）。
