- I use Parseapi to upload and save the video file on the server Parse.comfor the application.
. I am currently using the following code from the Parse Documentation to upload a video file to Parse Server:
File f = new File("/sdcard/video-2013-02-21-13-03-24.mp4");
byte[] videoUp = IOUtils.toByteArray( new FileInputStream(f));
ParseFile file = new ParseFile("testVideo1", videoUp);
file.saveInBackground(new SaveCallback() {
public void done(ParseException e) {
e.printStackTrace();
}
}, new ProgressCallback() {
public void done(Integer percentDone) {
System.out.println("Progress :" + percentDone);
}
});
- In the first , 100% printing is performed , which is the result of the operator System.out.printlnfrom method done()c Integeras a parameter, and immediately after that it goes to method done()c ParseExceptionas a parameter printing the next stack trace.
