我們可以通過Facebook SDK將視頻從Android設備的SD卡上傳到Facebook帳戶嗎?是否可以使用Facebook SDK將視頻從SD卡上傳到Facebook?
如果是這樣,那麼一些簡單的例子是什麼?
我們可以通過Facebook SDK將視頻從Android設備的SD卡上傳到Facebook帳戶嗎?是否可以使用Facebook SDK將視頻從SD卡上傳到Facebook?

是的,這是可能的!經過兩天的努力和研究,我能夠做到。 下面的代碼:
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AsyncFacebookRunner.RequestListener()
和readBytes()
的實現您的視頻文件轉換爲byte[]
的功能。 dataName
字符串應包含有效的文件擴展名(3gp,mp4等)。代碼如下:
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();
}
我從這個answer得到了這個函數。
當然,您需要擁有最新的Facebook SDK,但我們需要應用此patch來修復{"error":{"type":"OAuthException","message":"(#352) Video file format is not supported"}}
字符串響應錯誤。
就是這樣!我希望這有幫助!
補丁Util文件後,沒有得到結果。
我遇到了softy提到的問題。
我試圖與這在Android中......現在工作順利..一段時間後的視頻顯示在我的牆上(1分鐘內)。(可能是,Facebook的令人耳目一新的數據。)
String path="\mnt\sdcard\test.mp4";
if (new File(path).exists()) {
try {
byte[] data = null;
String dataPath = new File(path).getAbsolutePath();
Log.e("", dataPath);
String dataMsg = "It is the short movie created";
Bundle param;
InputStream is = null;
try {
is = new FileInputStream(dataPath);
data = readBytes(is);
param = new Bundle();
// param.putString("filename", "" + new
// File(path).getName());
// param.putString("mimeType", "video/mp4");
param.putString("message", dataMsg);
param.putString("title", "title");
param.putString("contentType", "video/quicktime");
param.putByteArray("video.mov", data);
Utility.mAsyncRunner.request("me/videos", param, "POST",
new FBRequestListener(), null);
Toast.makeText(getContext(), "Uploading...",
Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
} else {
Toast.makeText(getContext(), "No videos found in these dates",
Toast.LENGTH_SHORT).show();
}
FBRequestListener.java
public class FBRequestListener implements RequestListener {
@Override
public void onComplete(String response, Object state) {
Log.e("response", response);
// Log.e("state", state.toString());
}
@Override
public void onIOException(IOException e, Object state) {
Log.e("", "onIOException");
e.printStackTrace();
}
@Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
Log.e("", "onFileNotFoundException");
e.printStackTrace();
}
@Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
Log.e("", "onMalformedURLException");
e.printStackTrace();
}
@Override
public void onFacebookError(FacebookError e, Object state) {
Log.e("", "onFacebookError");
e.printStackTrace();
}
}
有了新的Facebook SDK 3.5的發佈,視頻上傳已經變得更加容易。 如果您正在使用SDK 3.5或以上這裏是視頻上傳至Facebook
//Path to the video, Ex: path = Environment.getExternalStorageDirectory() + File.separator + "myVideo.mp4";
String path;
//get the current active facebook session
Session session = Session.getActiveSession();
//If the session is open
if(session.isOpened()) {
//Get the list of permissions associated with the session
List<String> permissions = session.getPermissions();
//if the session does not have video_upload permission
if(!permissions.contains("video_upload")) {
//Get the permission from user to upload the video to facebook
Session.NewPermissionsRequest newPermissionsRequest = new Session
.NewPermissionsRequest(this, Arrays.asList("video_upload"));
session.requestNewReadPermissions(newPermissionsRequest);
}
//Create a new file for the video
File file = new File(path);
try {
//create a new request to upload video to the facebook
Request videoRequest = Request.newUploadVideoRequest(session, file, new Request.Callback() {
@Override
public void onCompleted(Response response) {
if(response.getError()==null)
{
Toast.makeText(MainActivity.this, "video shared successfully", Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(MainActivity.this, response.getError().getErrorMessage(), Toast.LENGTH_SHORT).show();
}
}
});
//Execute the request in a separate thread
videoRequest.executeAsync();
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
//Session is not open
else {
Toast.makeText(getApplicationContext(), "Please login to facebook first", Toast.LENGTH_SHORT).show();
}
這也適用於我..但我怎麼能添加視頻標題? –
在新的Facebook SDK釋放的代碼,也有對Facebook主頁或牆壁上的一些變化,視頻上傳。
這裏是我用於在Facebook頁面或Facebook牆上上傳視頻的代碼。
你onActivityResult()
方法應該是這樣的
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == CAMERA_VIDEO && resultCode == Activity.RESULT_OK){
String selectedVideoFilePath = GetFilePathFromDevice.getPath(this, data.getData());
final byte[] datas = readBytes(selectedVideoFilePath);
PostVideo(datas, selectedVideoFilePath);
}
}
這裏是onActivityResult().
public byte[] readBytes(String dataPath) throws IOException {
InputStream inputStream = new FileInputStream(dataPath);
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
byte[] buffer = new byte[1024];
int len;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
return byteBuffer.toByteArray();
}
public void PostVideo(byte[] VideoBytes, String filePath) {
String url;
url = "/me/videos";
AccessToken token = AccessToken.getCurrentAccessToken();
if (token != null) {
Bundle param = new Bundle();
param.putByteArray("video." + getFileExt(filePath), VideoBytes);
param.putString("description", "sample video");
new GraphRequest(token,url, param, HttpMethod.POST, new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
Log.e("New Post", "Res =" + response.toString());
dialog.dismiss();
if (response != null && response.getJSONObject() != null && response.getJSONObject().has("id")) {
Log.e("New Post", "Success");
Toast.makeText(NewPostActivity.this, "Video posted successfully.", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(NewPostActivity.this, "Error in posting Video.", Toast.LENGTH_SHORT).show();
}
setResult(Activity.RESULT_OK, new Intent());
finish();
}
}).executeAsync();
}
}
public static String getFileExt(String fileName) {
return fileName.substring((fileName.lastIndexOf(".") + 1), fileName.length());
}
使用的所有方法在這裏是onActivityResult()

嗨,我用你的回答你已發佈。它工作正常,但我有這個錯誤{「錯誤」:{「type」:「OAuthException」,「消息」:「(#352)不支持視頻文件格式」}}。你給了最新的補丁來解決這個錯誤。所以請告訴我,我必須更改util類中的代碼 – Ramakrishna
,請告訴我我必須更改Util類中的代碼。 – Ramakrishna
我編輯了我的答案,爲視頻文件名添加了一個附加參數。此外,修補程序需要在Util類中應用可以找到這個鏈接:[patch_link](https://github.com/johnmph/facebook-android-sdk/commit/d0e6ca9d3ecfbe964e72803fdd340cfeafa6ee2e) – Erick
