当我尝试从我的 android 应用程序将不同格式的视频（包括 .mp4 和 .3gp 文件）上传到 facebook 时，我在我的 facebook 帐户中收到一条通知，提示“无法处理您的视频。请访问视频帮助页面了解关于常见问题”。请帮助我。postToWall 功能将视频发布到 facebook。

data = readBytes(is);

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();
