splitFileList list Contain 2 Size data a,b i want to execute synchronously one by one i.e loop start from 0 then it should complete asynk task for 0 then if loop will go one then it should complete please suggest me how to execute asynk task one by one in for loop .
You can't run synchronously by AsyncTask You must use thread some thing like this:
Thread t = new Thread(

tempFileName = splitFileList.get(i);

File myfile = new File(splitFileCheckinDirectory);
if (!myfile.exists()) {
trimVideo(getExternalFilesDir(null) + "/" + getFileNameFromFilePath(mFilePath), mStartTImelist.get(i), mEndTimelist.get(i) - mStartTImelist.get(i)); //here you can run synchronously work
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
});
t.start();
try {
t.join();
.....

If you can't implement #Hazem answer you can go with another approach.
For this you need to maintain counter for each of your data and forget about for loop.
First you need to call asynctask for first position of your list.Something like this:
if(list1.size() > 0) {
fileCounter=0;
tempFileName = splitFileList.get(fileCounter);
String splitFileCheckinDirectory = splitVideofilepath + Constant.SPLIT_VIDEO + "/" + tempFileName + Constant.FILE_EXTENSION;
File myfile = new File(splitFileCheckinDirectory);
if (!myfile.exists()) {
new TrimmVideo(getExternalFilesDir(null) + "/" + getFileNameFromFilePath(mFilePath), mStartTImelist.get(i), mEndTimelist.get(i) - mStartTImelist.get(i)).execute();
}
}
Then in onPostExecute of your asyncTask
#Override
protected void onPostExecute(Void result) {
progressDialog.dismiss();
dbHandler.updateFlag(fileModel == null ? tempFileName : fileModel.getfilename());
btn_save_video.setVisibility(View.INVISIBLE);
super.onPostExecute(result);
// Update your counter here
fileCounter++;
// Check if your incremented counter doesn't exceed your list size
if(fileCounter < list1.size()) {
// Then call your asynctask again with updated counter data
empFileName = splitFileList.get(fileCounter);
String splitFileCheckinDirectory = splitVideofilepath + Constant.SPLIT_VIDEO + "/" + tempFileName + Constant.FILE_EXTENSION;
File myfile = new File(splitFileCheckinDirectory);
if (!myfile.exists()) {
new TrimmVideo(getExternalFilesDir(null) + "/" + getFileNameFromFilePath(mFilePath), mStartTImelist.get(i), mEndTimelist.get(i) - mStartTImelist.get(i)).execute();
}
}
}
Hope this will help you.

How to save uploaded file to sdcard folder , currently it stores to /data/data/cache folder with filename like "NanoHTTPD-some random number".
I am not able to copy it to any folder location in sdcard.
I would like to save the file to a pre-mentioned folder location in sdcard with the same name as the original file name was uploaded from my html page.
I have tried all sort of codes .But file copy fails all the time.
1)Not able to get correct location of temp file.
2)Not getting original filename that the form was posted with

To allow multiple file upload:
<input type="file" name="filename" multiple>
The same issue existed in the 2.2.1 branch. Following the same logic, I fixed the same function with a few lines of code change.
Add a counter pcount at the beginning of the function:
private void decodeMultipartFormData(String boundary, String encoding, ByteBuffer fbuf, Map<String, String> parms, Map<String, String> files) throws ResponseException {
int pcount = 1;
try {
Then use the counter to update the keyname if filename is not empty:
while (matcher.find()) {
String key = matcher.group(1);
if ("name".equalsIgnoreCase(key)) {
part_name = matcher.group(2);
} else if ("filename".equalsIgnoreCase(key)) {
file_name = matcher.group(2);
// add these two line to support multiple
// files uploaded using the same field Id
if (!file_name.isEmpty()) {
if (pcount > 0)
part_name = part_name + String.valueOf(pcount++);
else
pcount++;
}
}
}
Maybe late, but just for latecommers just like me.
Explained before, the client use okhttp upload a file just like the follow code：
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
//sourceFile is a File as you know
.addFormDataPart("image_file_1", "logo-square1.png", RequestBody.create(MediaType.parse("image/png"), sourceFile))
.build();
Request request = new Request.Builder()
.url(url)
.post(requestBody)
.build();
Response response = client.newCall(request).execute();
The follow code is what you want
#Override
public Response serve(IHTTPSession session) {
Method method = session.getMethod();
// ▼ 1、parse post body ▼
Map<String, String> files = new HashMap<>();
if (Method.POST.equals(method) || Method.PUT.equals(method)) {
try {
session.parseBody(files);
} catch (IOException ioe) {
return getResponse("Internal Error IO Exception: " + ioe.getMessage());
} catch (ResponseException re) {
return newFixedLengthResponse(re.getStatus(), MIME_PLAINTEXT, re.getMessage());
}
}
//after the body parsed, by default nanoHTTPD will save the file to cache and put it into params( "image_file_1" as key and the value is "logo-square1.png");
//files key is just like "image_file_1", and the value is nanoHTTPD's template file path in cache
// ▲ 1、parse post body ▲
// ▼ 2、copy file to target path xiaoyee ▼
Map<String, String> params = session.getParms();
for (Map.Entry<String, String> entry : params.entrySet()) {
final String paramsKey = entry.getKey();
if (paramsKey.contains("image_file_1")) {
final String tmpFilePath = files.get(paramsKey);
final String fileName = paramsKey;
final File tmpFile = new File(tmpFilePath);
final File targetFile = new File(mCurrentDir + fileName);
LogUtil.log("copy file now, source file path: %s,target file path:%s", tmpFile.getAbsoluteFile(), targetFile.getAbsoluteFile());
//a copy file method just what you like
copyFile(tmpFile, targetFile);
//maybe you should put the follow code out
return getResponse("Success");
}
}
// ▲ 2、copy file to target path xiaoyee ▲
return getResponse("Error 404: File not found");
}
I am using Sebastian Annies example for the mp4parser where I append 3 videos. The result should be one video that plays all the three videos simultaneously. However, I get one video that plays the last video three times. Here is my code...
// int i = number of videos....
try {
String[] f = new String[i];
for (int count = 0; count < i; count++) {
f[count] = "/sdcard/vid" + i + ".mp4";
}
Movie[] inMovies = new Movie[i];
for (int count = 0; count < i; count++) {
inMovies[count] = MovieCreator.build(f[count]);
}
List<Track> videoTracks = new LinkedList<Track>();
List<Track> audioTracks = new LinkedList<Track>();
for (Movie m : inMovies) {
for (Track t : m.getTracks()) {
if (t.getHandler().equals("soun")) {
audioTracks.add(t);
}
if (t.getHandler().equals("vide")) {
videoTracks.add(t);
}
}
}
Movie result = new Movie();
if (audioTracks.size() > 0) {
result.addTrack(new AppendTrack(audioTracks.toArray(new Track[audioTracks.size()])));
}
if (videoTracks.size() > 0) {
result.addTrack(new AppendTrack(videoTracks.toArray(new Track[videoTracks.size()])));
}
Container out = new DefaultMp4Builder().build(result);
FileChannel fc = new RandomAccessFile(String.format
("/sdcard/output.mp4"),
"rw").getChannel();
out.writeContainer(fc);
fc.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
VideoView v = (VideoView) findViewById(R.id.videoView1);
// v.setVideoPath("/sdcard/aaa" + i + ".mp4");
v.setVideoPath("/sdcard/output.mp4");
v.setMediaController(new MediaController(this));
v.start();
I dont know why it isn't doing what it's supposed to do. Please help me. Thanks
Your problem is that you're filling the input file-names with the same file:
for (int count = 0; count < i; count++) {
f[count] = "/sdcard/vid" + i + ".mp4";
}
Should be
for (int count = 0; count < i; count++) {
f[count] = "/sdcard/vid" + count + ".mp4";
}
You might be better off, for readability, to make i the loop variable, and have count be the number of files.
