我们能否通过Facebook SDK将Android设备SD卡上的视频上传到Facebook账户?
如果可以,有哪些简单的示例?
我们能否通过Facebook SDK将Android设备SD卡上的视频上传到Facebook账户?

是的,这是可能的!经过两天的尝试和研究,我成功了。下面是代码:
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()
的实现,而readBytes()
是将您的视频文件转换为byte[]
的函数。 dataName
字符串应包含有效的文件扩展名(3gp,mp4等)。 代码如下:
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();
}
我从这个答案中得到了这个函数。
当然,你需要拥有最新的Facebook SDK,但我们需要应用这个补丁来修复{"error":{"type":"OAuthException","message":"(#352) Video file format is not supported"}}
字符串响应错误。
就是这样了!希望能对你有所帮助!
//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();
}
onActivityResult()
方法应该像这样。@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);
}
}
这里是onActivityResult()
中使用的所有方法。
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());
}
这里是GetFilePathFromDevice
类,用于在onActivityResult()
中从URI获取文件路径。
@SuppressLint("NewApi")
public final class GetFilePathFromDevice {
/**

final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];

try {

if (cursor != null && cursor.moveToFirst()) {

return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());

}
在修补Util文件后,没有得到结果。
我遇到了软件提到的问题。
我在Android上尝试了这个...现在成功运行了..视频在一段时间后显示在我的墙上(可能是因为Facebook正在刷新数据..)
String path="\mnt\sdcard\test.mp4";
if (new File(path).exists()) {

byte[] data = null;
String dataPath = new File(path).getAbsolutePath();
Log.e("", dataPath);

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);
