使用Facebook SDK将视频从SD卡上传到Facebook？ [英] Is uploading videos from an SD Card to Facebook possible with the Facebook SDK?

问题描述

我们可以通过Facebook SDK从Android设备的SD卡上传视频到Facebook帐户吗？

Can we upload videos from an Android device's SD Card to a Facebook account via the Facebook SDK?

如果是，有什么简单的例子？

If so, what are some simple examples?

推荐答案

是， 有可能的！经过两天的试用和研究，我能够做到这一点。
这里是代码：

Yes, it is possible! After two days of trying and researching, I was able to do it. Here's the code:

byte[] data = null;
String dataPath = "/mnt/sdcard/KaraokeVideos/myvideo.3gp";
String dataMsg = "Your video description here.";
Bundle param;
facebook = new Facebook(FB_APP_ID);
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
InputStream is = null;
try {
    is = new FileInputStream(dataPath);
    data = readBytes(is);
    param = new Bundle();
    param.putString("message", dataMsg);
    param.putString("filename", dataName);
    param.putByteArray("video", data);
    mAsyncRunner.request("me/videos", param, "POST", new fbRequestListener(), null);
}
catch (FileNotFoundException e) {
   e.printStackTrace();
}
catch (IOException e) {
   e.printStackTrace();
}

其中 fbRequestListener（）是的实现AsyncFacebookRunner.RequestListener（）和 readBytes（）是将视频文件转换为字节[] 。 dataName 字符串应包含有效的文件扩展名（3gp，mp4等）。代码如下：

where fbRequestListener() is an implementation of AsyncFacebookRunner.RequestListener() and readBytes() is a function of converting your video file to byte[]. The dataName string should include a valid file extension (3gp, mp4, etc.). The code is as follows:

public byte[] readBytes(InputStream inputStream) throws IOException {
    // This dynamically extends to take the bytes you read.
    ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();

    // This is storage overwritten on each iteration with bytes.
    int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];

    // We need to know how may bytes were read to write them to the byteBuffer.
    int len = 0;
    while ((len = inputStream.read(buffer)) != -1) {
        byteBuffer.write(buffer, 0, len);
    }

    // And then we can return your byte array.
    return byteBuffer.toByteArray();
}

我从这个 answer 。

当然，您需要拥有最新的Facebook SDK，但是我们需要应用这个补丁修复 {error：{type：OAuthException，message：（＃352）不支持视频文件格式}} / code> string response error。

Of course, you need to have the latest Facebook SDK, but we need to apply this patch to fix the {"error":{"type":"OAuthException","message":"(#352) Video file format is not supported"}} string response error.

就是这样！我希望这有帮助！

And that's it! I hope this helps!
