Converting from URI
to byte[]
, then byte[]
is stored to file: 从
URI
转换为byte[]
,然后将byte[]
存储到文件:
InputStream videoStream = getActivity().getContentResolver().openInputStream(videoUri);
byte bytes[] = ByteStreams.toByteArray(videoStream );
videoFile = new File("abcd.mp4");
FileOutputStream out = new FileOutputStream(videoFile);
out.write(bytes);
out.close();
Can you try that one : 你能尝试一下吗:
public String DownloadFromUrl(String DownloadUrl, String fileName) {
File SDCardRoot = null;
try {
SDCardRoot = Environment.getExternalStorageDirectory();
File files = new File(SDCardRoot+fileName);
int sizeoffile;
if(!files.exists())
{
File root = android.os.Environment.getExternalStorageDirectory();
File dir = new File (root.getAbsolutePath());
if(dir.exists()==false) {
dir.mkdirs();
}
URL url = new URL(DownloadUrl);
File file = new File(dir, fileName);
/* Open a connection to that URL. */
URLConnection ucon = url.openConnection();
sizeoffile = ucon.getContentLength();
Log.d("SIZEOFFILE: ", sizeoffile+" BYTE");
/*
* Define InputStreams to read from the URLConnection.
*/
InputStream is = ucon.getInputStream();
BufferedInputStream bis = new BufferedInputStream(is);
/*
* Read bytes to the Buffer until there is nothing more to read(-1).
*/
ByteArrayBuffer baf = new ByteArrayBuffer(5000);
int current = 0;
while ((current = bis.read()) != -1) {
baf.append((byte) current);
}
/* Convert the Bytes read to a String. */
FileOutputStream fos = new FileOutputStream(file);
fos.write(baf.toByteArray());
fos.flush();
fos.close();
}
}
catch (IOException e) {
e.getMessage();
}
return SDCardRoot+fileName; }
Finally i found the solution.
Uri videoUri = data.getData();
File videoFile = null;
final InputStream imageStream;
try {
imageStream = getActivity().getContentResolver().openInputStream(videoUri);
byte bytes[] = ByteStreams.toByteArray(imageStream);//IStoByteArray(imageStream);
videoFile = new File(Environment.getExternalStorageDirectory()+ "/"+System.currentTimeMillis()+".mp4");
videoFile.createNewFile();
FileOutputStream out = new FileOutputStream(videoFile);
out.write(bytes);
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
}catch (Exception ee){
ee.printStackTrace();
}
I have recently encountered this. 我最近遇到了这个。
I first discovered that what I'm receiving is a picture rather than a video. 我首先发现我收到的是图片而不是视频。
But I didn't understand why Facebook is successfully playing the online video I shared via (Google+'s) Photo. 但是我不明白为什么Facebook成功地播放了我通过(Google+的)照片分享的在线视频。
I then occasionally discovered that the file they're currently giving is a GIF with the original extension in the MediaStore.Images.Media.DISPLAY_NAME
section of the contentUri. 然后,我偶尔发现他们当前提供的文件是contentUri的
MediaStore.Images.Media.DISPLAY_NAME
部分中具有原始扩展名的GIF 。
Eeek! eek!
