I'm splitting an encrypted video into 4 parts using this code
public class SplitVideoFile {
private static String result;
static ArrayList<String>update=new ArrayList<>();
public static String main(File file) {
try {
// File file = new File("C:/Documents/Despicable Me 2 - Trailer (HD) - YouTube.mp4");//File read from Source folder to Split.
if (file.exists()) {
String videoFileName = file.getName().substring(0, file.getName().lastIndexOf(".")); // Name of the videoFile without extension
// String path = Environment.getDataDirectory().getAbsolutePath().toString() + "/storage/emulated/0/Videointegrity";
String path = "/storage/emulated/0/Videointegrity";
// File myDir = new File(getFile, "folder");
//myDir.mkdir();
File splitFile = new File(path.concat("/").concat(videoFileName));//Destination folder to save.
if (!splitFile.exists()) {
splitFile.mkdirs();
Log.d("Directory Created -> ", splitFile.getAbsolutePath());
}
int i = 01;// Files count starts from 1
InputStream inputStream = new FileInputStream(file);
String videoFile = splitFile.getAbsolutePath() +"/"+ String.format("%02d", i) +"_"+ file.getName();// Location to save the files which are Split from the original file.
OutputStream outputStream = new FileOutputStream(videoFile);
Log.d("File Created Location: ", videoFile);
update.add("File Created Location: ".concat(videoFile));
int totalPartsToSplit =4 ;// Total files to split.
int splitSize = inputStream.available() / totalPartsToSplit;
int streamSize = 0;
int read = 0;
while ((read = inputStream.read()) != -1) {
if (splitSize == streamSize) {
if (i != totalPartsToSplit) {
i++;
String fileCount = String.format("%02d", i); // output will be 1 is 01, 2 is 02
videoFile = splitFile.getAbsolutePath() +"/"+ fileCount +"_"+ file.getName();
outputStream = new FileOutputStream(videoFile);
Log.d("File Created Location: ", videoFile);
streamSize = 0;
}
}
outputStream.write(read);
streamSize++;
}
inputStream.close();
outputStream.close();
Log.d("Total files Split ->", String.valueOf(totalPartsToSplit));
result="success";
} else {
System.err.println(file.getAbsolutePath() +" File Not Found.");
result="failed";
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
public ArrayList<String> getUpdate()
{
return update;
}
And in my activity file i call this using async task's doinbackground method like below
protected String doInBackground(Void...arg0) {
Log.d(TAG + " DoINBackGround", "On doInBackground...");
File encvideo=new File(epath.getText().toString());
SplitVideoFile split=new SplitVideoFile();
String result=split.main(encvideo);
publishProgress(1);
return result;
}
Even though it splits the video, it takes too much of time to do the process.
How can I speed them up. As I'm showing a progress bar in preexecute method it looks like the user sees the progress bar for a long time, which I don't want.
I am trying to check whether device having external storage or not by using external storage path like this given below
if (new File("/ext_card/").exists()) {
specialPath = "/ext_card/";
} else if (new File("/mnt/sdcard/external_sd/").exists()) {
specialPath = "/mnt/sdcard/external_sd/";
} else if (new File("/storage/extSdCard/").exists()) {
specialPath = "/storage/extSdCard/";
} else if (new File("/mnt/extSdCard/").exists()) {
specialPath = "/mnt/extSdCard/";
} else if (new File("/mnt/sdcard/external_sd/").exists()) {
specialPath = "/mnt/sdcard/external_sd/";
} else if (new File("storage/sdcard1/").exists()) {
specialPath = "storage/sdcard1/";
}
But in marshmallow I con't find this path and while checking using ES FILEMANAGER, they give like storage/3263-3131 in Moto G 3rd generation. While check in other marshmallow devices that numbers getting differ. Please help me to check that marshmallow device have external storage or not? and if storage found means how to get the path of that external storage?
Note:- I gave permission for storage in my application and also enabled storage permission in settings for my app.
Thanks in advance and did you find any mistake in my question please crt it. thank you again.
Here's my solution, which is guaranteed to work till Android 7.0 Nougat:
/* returns external storage paths (directory of external memory card) as array of Strings */
public String[] getExternalStorageDirectories() {
List<String> results = new ArrayList<>();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //Method 1 for KitKat & above
File[] externalDirs = getExternalFilesDirs(null);
String internalRoot = Environment.getExternalStorageDirectory().getAbsolutePath().toLowerCase();
for (File file : externalDirs) {
if(file==null) //solved NPE on some Lollipop devices
continue;
String path = file.getPath().split("/Android")[0];
if(path.toLowerCase().startsWith(internalRoot))
continue;
boolean addPath = false;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
addPath = Environment.isExternalStorageRemovable(file);
}
else{
addPath = Environment.MEDIA_MOUNTED.equals(EnvironmentCompat.getStorageState(file));
}
if(addPath){
results.add(path);
}
}
}
if(results.isEmpty()) { //Method 2 for all versions
// better variation of: http://stackoverflow.com/a/40123073/5002496
String output = "";
try {
final Process process = new ProcessBuilder().command("mount | grep /dev/block/vold")
.redirectErrorStream(true).start();
process.waitFor();
final InputStream is = process.getInputStream();
final byte[] buffer = new byte[1024];
while (is.read(buffer) != -1) {
output = output + new String(buffer);
}
is.close();
} catch (final Exception e) {
e.printStackTrace();
}
if(!output.trim().isEmpty()) {
String devicePoints[] = output.split("\n");
for(String voldPoint: devicePoints) {
results.add(voldPoint.split(" ")[2]);
}
}
}
//Below few lines is to remove paths which may not be external memory card, like OTG (feel free to comment them out)
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
for (int i = 0; i < results.size(); i++) {
if (!results.get(i).toLowerCase().matches(".*[0-9a-f]{4}[-][0-9a-f]{4}")) {
Log.d(LOG_TAG, results.get(i) + " might not be extSDcard");
results.remove(i--);
}
}
} else {
for (int i = 0; i < results.size(); i++) {
if (!results.get(i).toLowerCase().contains("ext") && !results.get(i).toLowerCase().contains("sdcard")) {
Log.d(LOG_TAG, results.get(i)+" might not be extSDcard");
results.remove(i--);
}
}
}
String[] storageDirectories = new String[results.size()];
for(int i=0; i<results.size(); ++i) storageDirectories[i] = results.get(i);
return storageDirectories;
}
I found the solution for this over here https://stackoverflow.com/a/13648873/842607
The code is -
public static HashSet<String> getExternalMounts() {
final HashSet<String> out = new HashSet<String>();
String reg = "(?i).*vold.*(vfat|ntfs|exfat|fat32|ext3|ext4).*rw.*";
String s = "";
try {
final Process process = new ProcessBuilder().command("mount")
.redirectErrorStream(true).start();
process.waitFor();
final InputStream is = process.getInputStream();
final byte[] buffer = new byte[1024];
while (is.read(buffer) != -1) {
s = s + new String(buffer);
}
is.close();
} catch (final Exception e) {
e.printStackTrace();
}
// parse output
final String[] lines = s.split("\n");
for (String line : lines) {
if (!line.toLowerCase(Locale.US).contains("asec")) {
if (line.matches(reg)) {
String[] parts = line.split(" ");
for (String part : parts) {
if (part.startsWith("/"))
if (!part.toLowerCase(Locale.US).contains("vold"))
out.add(part);
}
}
}
}
return out;
}

in this i have redmi note prime 2.and i have no memory card.so when i found path and File[] externalDirs = getExternalFilesDirs(null); give null second postion value of file[].
}
I am able to change file extensions, for example, from ".mp4" to ".xmp4" but instead of changing extension, i simply want to add a "." before a file name for example "mikey.jpg" to ".mikey.jpg". how do i do that?
public static final String[] TARGET_EXTENSIONS = { "mp4", "mp3", "mp55", "other" };
public void walkdir(File dir) {
File listFile[] = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
String fPath = listFile[i].getPath();
for (String ext : TARGET_EXTENSIONS) {
fPath = fPath.replace("." + ext, ".x" + ext);
}
listFile[i].renameTo(new File(fPath));
}
}
}
}
here is the full code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
view = (LinearLayout) findViewById(R.id.view);
// getting SDcard root path
File dir = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath());
walkdir(dir);
}
public static final String[] TARGET_EXTENSIONS = { "mp4", "mp3", "avi", "other" };
public void walkdir(File dir) {
File listFile[] = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
String fPath = listFile[i].getPath();
for (String ext : TARGET_EXTENSIONS) {
fPath = fPath.replace("." + ext, ".x" + ext);
}
listFile[i].renameTo(new File(fPath));
}
}
}
}
}
first you do String fileName = listFile[i].getName(); , which should give you the name, next you do String fullPath = listFile[i].getAbsolutePath(); to get the full path, then you do int indexOfFileNameStart = fullPath.lastIndexOf(fileName) , then you get a string builder instance from fullPath like so StringBuilder sb = new StringBuilder(fullPath); , now you call the insert method on sb sb.insert(indexOfFileNameStart, "."), now sb should have the string you desire, just construct it to string sb.toString()
Ill add this in code
private String putDotBeforeFileName(File file) {
String fileName = file.getName();
String fullPath = file.getAbsolutePath();
int indexOfFileNameStart = fullPath.lastIndexOf(fileName);
StringBuilder sb = new StringBuilder(fullPath);
sb.insert(indexOfFileNameStart, ".");
String myRequiredFileName = sb.toString();
file.renameTo(new File(myRequiredFileName));
return myRequiredFileName;
}
EDIT
This is how you can use the above method in your code
public void walkdir(File dir) {
File listFile[] = dir.listFiles();
if (listFile != null) {
for (int i = 0; i < listFile.length; i++) {
if (listFile[i].isDirectory()) {
walkdir(listFile[i]);
} else {
String fPath = listFile[i].getPath();
for (String ext : TARGET_EXTENSIONS) {
if(fPath.endsWith(ext)) {
putDotBeforeFileName(listFile[i]);
}
}
}
}
}
}
I want to get External SdCard path on devices if it available. by using Environment.getExternalStorageDirectory().getAbsolutePath() I can get the path to the Internal Storage. So I used below class for detecting External storage.

map.put(key, root);
}
}
}
mMounts.clear();
if(map.isEmpty()){
map.put(SD_CARD, Environment.getExternalStorageDirectory());
}
return map;
}
Example usage
Map <String, File> externalLocations = ExternalStorage.getAllStorageLocations();
File sdCard = externalLocations.get(ExternalStorage.SD_CARD);
File externalSdCard=externalLocations.get(ExternalStorage.EXTERNAL_SD_CARD);
on some device like Samsung Galaxy S3 it detects External SdCard correctly and return /storage/extSdCard for path to the External SdCard but on other devices like Sony Experia Z1 and Z2 it can't detect External Sdcard and give me the path to the Internal Storage. How can I solve this problem?

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");
}
