cameraKit-android output video

Does anyone use the CameraKit-Android by gogopop? My problem is that I set the listener of video but the outputfile is null. Anyone know how to solve it?
this is my code:
cameraView.getCamera().setVideoQuality(CameraKit.Constants.VIDEO_QUALITY_720P);
cameraView.getCamera().startRecordingVideo();
cameraView.getCamera().setCameraListener(new CameraListener() {
#Override
public void onVideoTaken(final File video) {
super.onVideoTaken(video);
/* new Thread(new Runnable() {
#Override
public void run() {
final byte[] videoBytes = FileUtils.File2byte(video.getAbsolutePath());
if (!isExit) {
new Thread(new Runnable() {
#Override
public void run() {
saveFile(videoBytes);
}
}).start();
}
isExit = false;
}
}).start();*/
}
});
I've used to make a new file to save the mp4, but when I'm recording a video longer than one minute, the app is OOM. Anyone can help me? Thanks.

i slove it. this is not cameraKit-android issuse. it is the Android 's problem,it have two point:
the file is exit, but you don't notification the system. so you should :
cameraView.getCamera().setCameraListener(new CameraListener() {
#Override
public void onVideoTaken(final File video) {
super.onVideoTaken(video);
//notify system refresh
Uri localUri = Uri.fromFile(video);
Intent localIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, localUri);
sendBroadcast(localIntent);
try this guys idea, i use it save susscess:
String path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/milai/";
File appDir = new File(path);
if (!appDir.exists()) {
appDir.mkdir();
}
mVideoFile = new File(mPreview.getView().getContext().getExternalFilesDir(null), getPicTime()+".mp4");
String myFile = path+getPicTime()+".mp4";
mMediaRecorder.setOutputFile(myFile);
it look the same , but i don't know why success. if eveybody have other problem, can ask me . i will try to help you.

My solution for this problem;
public static void saveVideoToFile( File video) {
try {
File newfile;
FileInputStream fileInputStream = new FileInputStream(video);
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getAbsolutePath() + "/" + "Your File Name" + "/");
if (!dir.exists()) {
dir.mkdirs();
}
newfile = new File(dir, "save_" + System.currentTimeMillis() + ".mp4");
if (newfile.exists()) newfile.delete();
OutputStream out = new FileOutputStream(newfile);
// Copy the bits from instream to outstream
byte[] buf = new byte[1024];
int len;
while ((len = fileInputStream.read(buf)) > 0) {
out.write(buf, 0, len);
}
fileInputStream.close();
out.close();
MyLog.log("Copy file successful.");
} catch (Exception e) {
e.printStackTrace();
}
}

Android:How to Copy a Folder From 'assets' Includes files and folders to sdcard [duplicate]

I'm trying to use a directory that I have in my assets folder and access it as a File. Is it possible to access something in the Assets directory as a File? If not, how can I copy a directory from the Assets folder to the application's local directory?
I would copy a file like so:
try
{
InputStream stream = this.getAssets().open("myFile");
OutputStream output = new BufferedOutputStream(new FileOutputStream(this.getFilesDir() + "/myNewFile"));
byte data[] = new byte[1024];
int count;
while((count = stream.read(data)) != -1)
{
output.write(data, 0, count);
}
output.flush();
output.close();
stream.close();
}
catch(IOException e)
{
e.printStackTrace();
}
However, I'm not sure how I would be able to do this for a directory.
I would rather not build my infrastructure around something that doesn't work, so how would I copy a directory from Assets to a local directory, or is it possible to access a directory in my Assets as a File?
EDIT
This is how I solved it for my own project:
InputStream stream = null;
OutputStream output = null;
for(String fileName : this.getAssets().list("demopass"))
{
stream = this.getAssets().open("directoryName/" + fileName);
output = new BufferedOutputStream(new FileOutputStream(this.getFilesDir() + "/newDirectory/" + fileName));
byte data[] = new byte[1024];
int count;
while((count = stream.read(data)) != -1)
{
output.write(data, 0, count);
}
output.flush();
output.close();
stream.close();
stream = null;
output = null;
}

As suggested by dmaxi in comment above, you can use his link, with this code:
void displayFiles (AssetManager mgr, String path) {
try {
String list[] = mgr.list(path);
if (list != null)
for (int i=0; i<list.length; ++i)
{
Log.v("Assets:", path +"/"+ list[i]);
displayFiles(mgr, path + "/" + list[i]);
}
} catch (IOException e) {
Log.v("List error:", "can't list" + path);
}
}
I took it on this link.
Maybe you can combine this code with precedent one.

You can use following method for copying your asset folder to a location in your SD Card. From your calling method just call moveAssetToStorageDir("") for moving entire asset folder. In case of sub folders you can specify the relative path inside the asset folder.
public void moveAssetToStorageDir(String path){
File file = getExternalFilesDir(null);
String rootPath = file.getPath() + "/" + path;
try{
String [] paths = getAssets().list(path);
for(int i=0; i<paths.length; i++){
if(paths[i].indexOf(".")==-1){
File dir = new File(rootPath + paths[i]);
dir.mkdir();
moveAssetToStorageDir(paths[i]);
}else {
File dest = null;
InputStream in = null;
if(path.length() == 0) {
dest = new File(rootPath + paths[i]);
in = getAssets().open(paths[i]);
}else{
dest = new File(rootPath + "/" + paths[i]);
in = getAssets().open(path + "/" + paths[i]);
}
dest.createNewFile();
FileOutputStream out = new FileOutputStream(dest);
byte [] buff = new byte[in.available()];
in.read(buff);
out.write(buff);
out.close();
in.close();
}
}
}catch (Exception exp){
exp.printStackTrace();
}
}

Here is the clean version of the OP's answer.
public void copyAssetFolderToFolder(Context activity, String assetsFolder, File destinationFolder) {

try {

For future reference, please save everyone the trouble and post contextually complete source listings. This site can be a great coding resource for beginners and experts, if only you would post complete answers. One cannot assume that anyone else "understands" where a random block of code belongs, or the context that the code is supposed to be executed within.
This sample calls for the context of an activity, which houses the getAssets() method. Within the android platform, their are other classes besides Activity which can supply this context. One example is the (generic reference) Service class.

Moving an arbitrary folder of directories and files from Assets
The thing is... Assets are special. You cannot wrap it in a File object and ask isDirectory() and you cannot pass these assets into the NDK. So it is better to wrap them up and move them to a cache directory or onto the SDCard which is why you're here.
I've seen many SO answers that involve some version of rolling through an array of fileOrDirectoryName strings and then creating directories followed by a recursive call and copying individual files. Which leads you to create a folder or file and you cannot tell from an asset which you have.
Make it a Zip file
My recommendation is to take each arbitrary collection of assets that you want to ship to the SDCard or an internal cache folder and Zip it up. The problem is structured in an way more compatible with the Assets concept.
AssetManager assetManager = context.getAssets();
String fullAssetPath = fromAssetPath + "/" + zipFilename;
String toPath = "/wherever/I/want";
try {
InputStream inputStream = assetManager.open(fullAssetPath);
ZipInputStream zipInputStream = new ZipInputStream(new BufferedInputStream(inputStream));
ZipEntry zipEntry;
byte[] buffer = new byte[8192];
while ((zipEntry = zipInputStream.getNextEntry()) != null) {
String fileOrDirectory = zipEntry.getName();
Uri.Builder builder = new Uri.Builder();
builder.scheme("file");
builder.appendPath(toPath);
builder.appendPath(fileOrDirectory);
String fullToPath = builder.build().getPath();
if (zipEntry.isDirectory()) {
File directory = new File(fullToPath);
directory.mkdirs();
continue;
}
FileOutputStream fileOutputStream = new FileOutputStream(fullToPath);
while ((count = zipInputStream.read(buffer)) != -1) {
fileOutputStream.write(buffer, 0, count);
}
fileOutputStream.close();
zipInputStream.closeEntry();
}
zipInputStream.close();
} catch (IOException e) {
Log.e(TAG, e.getLocalizedMessage());
}
Small note about buffer sizes
I've seen a lot of examples involving very small buffer sizes, for example 1024. Unless you just want to waste time feel free to try larger byte buffer sizes. Even my choice of 8192 is probably small on modern hardware.
Avoiding Stringy paths
Notice the use of Uri.Builder to construct the path. I much prefer this style of path construction over directory + "/" + file. Then you're in the business, for the sake of consistency avoiding assigning String d = "myDirectory/" or String f = "/file.txt" and other such string hacking nonsense.

Here's a recursive solution written in kotlin. It works with both files and dirs.
Usage - copyAssetDir(context, "<asset path>", "<dest dir>")
import android.content.Context
import java.io.File
import java.io.FileOutputStream
fun copyAssetDir(context: Context, assetPath: String, destDirPath: String) {
walkAssetDir(context, assetPath) {
copyAssetFile(context, it, "$destDirPath/$it")
}
}
fun walkAssetDir(context: Context, assetPath: String, callback: ((String) -> Unit)) {
val children = context.assets.list(assetPath) ?: return
if (children.isEmpty()) {
callback(assetPath)
} else {
for (child in children) {
walkAssetDir(context, "$assetPath/$child", callback)
}
}
}
fun copyAssetFile(context: Context, assetPath: String, destPath: String): File {
val destFile = File(destPath)
File(destFile.parent).mkdirs()
destFile.createNewFile()
context.assets.open(assetPath).use { src ->
FileOutputStream(destFile).use { dest ->
src.copyTo(dest)
}
}
return destFile
}

This is code for copy assets folder with directory and files both copy into sdcard folder...
this one works perfectly for me...
public void copyFileOrDir(String path) {
AssetManager assetManager = this.getAssets();
String assets[] = null;
try {
assets = assetManager.list(path);
if (assets.length == 0) {
copyFile(path);
} else {
String fullPath = "/data/data/" + this.getPackageName() + "/" + path;
File dir = new File(fullPath);
if (!dir.exists())
dir.mkdir();
for (int i = 0; i < assets.length; ++i) {
copyFileOrDir(path + "/" + assets[i]);
}
}
} catch (IOException ex) {
Log.e("tag", "I/O Exception", ex);
}
}
private void copyFile(String filename) {
AssetManager assetManager = this.getAssets();
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open(filename);
String newFileName = "/data/data/" + this.getPackageName() + "/" + filename;
out = new FileOutputStream(newFileName);
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
in.close();
in = null;
out.flush();
out.close();
out = null;
} catch (Exception e) {
Log.e("tag", e.getMessage());
}
}

I've seen a lot of examples involving very small buffer sizes, for example 1024. Unless you just want to waste time feel free to try larger byte buffer sizes. Even my choice of 8192 is probably small on modern hardware.
Avoiding Stringy paths
Notice the use of Uri.Builder to construct the path. I much prefer this style of path construction over directory + "/" + file. Then you're in the business, for the sake of consistency avoiding assigning String d = "myDirectory/" or String f = "/file.txt" and other such string hacking nonsense.

Here's a recursive solution written in kotlin. It works with both files and dirs.
Usage - copyAssetDir(context, "<asset path>", "<dest dir>")
import android.content.Context
import java.io.File
import java.io.FileOutputStream
fun copyAssetDir(context: Context, assetPath: String, destDirPath: String) {
walkAssetDir(context, assetPath) {
copyAssetFile(context, it, "$destDirPath/$it")
}
}
fun walkAssetDir(context: Context, assetPath: String, callback: ((String) -> Unit)) {
val children = context.assets.list(assetPath) ?: return
if (children.isEmpty()) {
callback(assetPath)
} else {
for (child in children) {
walkAssetDir(context, "$assetPath/$child", callback)
}
}
}
fun copyAssetFile(context: Context, assetPath: String, destPath: String): File {
val destFile = File(destPath)
File(destFile.parent).mkdirs()
destFile.createNewFile()
context.assets.open(assetPath).use { src ->
FileOutputStream(destFile).use { dest ->
src.copyTo(dest)
}
}
return destFile
}

This is code for copy assets folder with directory and files both copy into sdcard folder...
this one works perfectly for me...
public void copyFileOrDir(String path) {
AssetManager assetManager = this.getAssets();
String assets[] = null;
try {
assets = assetManager.list(path);
if (assets.length == 0) {
copyFile(path);
} else {
String fullPath = "/data/data/" + this.getPackageName() + "/" + path;
File dir = new File(fullPath);
if (!dir.exists())
dir.mkdir();
for (int i = 0; i < assets.length; ++i) {
copyFileOrDir(path + "/" + assets[i]);
}
}
} catch (IOException ex) {
Log.e("tag", "I/O Exception", ex);
}
}
private void copyFile(String filename) {
AssetManager assetManager = this.getAssets();
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open(filename);
String newFileName = "/data/data/" + this.getPackageName() + "/" + filename;
out = new FileOutputStream(newFileName);
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
in.close();
in = null;
out.flush();
out.close();
out = null;
} catch (Exception e) {
Log.e("tag", e.getMessage());
}
}

Building new directory and pushing files in Android

I have code that I know worked in another project of mine to create a new folder if it didn't already exist and place files from my project into it. But in my new project the code does nothing. What am i doing wrong?
File directory = new File(Environment.getExternalStorageDirectory()
+ File.separator + "testing");
directory.mkdirs();
File directory2 = new File(Environment.getExternalStorageDirectory()
+ File.separator + "CandooData" + File.separator + "Meds");
if (!(directory2.isDirectory())) {
directory2.mkdirs();
}
File directory3 = new File(Environment.getExternalStorageDirectory()
+ File.separator + "CandooData" + File.separator + "Meds");
String[] files;
if (directory3.isDirectory()) {
files = directory3.list();
if (files.length == 0) {
// directory is empty
CopyAssets("medsxml", "/Meds");
}
}

See the log via logcat.
It's possible that you've missed the WRITE_EXTERNAL_STORAGE permission.
mkdirs() will work just fine, not worse than mkdir().

Below is briefly example
File folder = new File(Environment.getExternalStorageDirectory()+"/Trip");
if(!folder.exists()){
folder.mkdir();
}
File newxmlfile = new File(Environment.getExternalStorageDirectory()+"/Trip/"+ RecordID +".xml");
try{
newxmlfile.createNewFile();
}catch(IOException e){
}

use this directory.mkdir(); instead of this directory.mkdirs();

I am using this below method to make directory and save the file in to it.
private static File APP_FILE_PATH = new File("/sdcard/SpeechTutor");
p_file_Side_Slow = new File("/sdcard/SpeechTutor/P_SideMovieSlow.mp4");
p_file_Side_Medium = new File("/sdcard/SpeechTutor/P_SideMovieMedium.mp4");
p_file_Side_Fast = new File("/sdcard/SpeechTutor/P_SideMovieFast.mp4");
p_file_Front_Slow = new File("/sdcard/SpeechTutor/P_FrontMovieSlow.mp4");
p_file_Front_Medium = new File("/sdcard/SpeechTutor/P_FrontMovieMedium.mp4");
p_file_Front_Fast = new File("/sdcard/SpeechTutor/P_FrontMovieFast.mp4");
if((!(p_file_Side_Slow.exists())) || (!(p_file_Side_Medium.exists())) || (!(p_file_Side_Fast.exists()))
|| (!(p_file_Front_Slow.exists()))|| (!(p_file_Front_Medium.exists()))||(!(p_file_Front_Fast.exists()))){
ArrayList<String> files = new ArrayList<String>();
files.add("P_SideMovieSlow.mp4");
files.add("P_SideMovieMedium.mp4");
files.add("P_SideMovieFast.mp4");
files.add("P_FrontMovieSlow.mp4");
files.add("P_FrontMovieMedium.mp4");
files.add("P_FrontMovieFast.mp4");
new myAsyncTask().execute(files);
}
// AsyncTass for the Progress Dialog and to do Background Process
private class myAsyncTask extends AsyncTask<ArrayList<String>, Void, Void> {
ArrayList<String> files;
ProgressDialog dialog;
#Override
protected void onPreExecute() {
dialog = ProgressDialog.show(MainScreenActivity.this, "Speech Tutor", "Loading...");
}
#Override
protected Void doInBackground(ArrayList<String>... params) {
files = params[0];
for (int i = 0; i < files.size(); i++) {
copyFileFromAssetsToSDCard(files.get(i));
} return null;
}
#Override
protected void onPostExecute(Void result) {
dialog.dismiss();
// myVideoThumbnail.setImageBitmap((Bitmap)ThumbnailUtils.createVideoThumbnail(p_file_Side_Slow.getAbsolutePath(),MediaStore.Video.Thumbnails.MINI_KIND));
// myVideoView.setVideoURI(p_uri_Side_Medium);
setVideoURI(sideShow, frontshow, slowShow, mediumShow, fastShow);
}
}
// Function to copy file from Assets to the SDCard
public void copyFileFromAssetsToSDCard(String fileFromAssets){
AssetManager is = this.getAssets();
InputStream fis;
try {
fis = is.open(fileFromAssets);
FileOutputStream fos;
if (!APP_FILE_PATH.exists()) {
APP_FILE_PATH.mkdirs();
}
fos = new FileOutputStream(new File(Environment.getExternalStorageDirectory()+"/SpeechTutor",fileFromAssets));
byte[] b = new byte[8];
int i;
while ((i = fis.read(b)) != -1) {
fos.write(b, 0, i);
}
fos.flush();
fos.close();
fis.close();
}
catch (IOException e1) {
e1.printStackTrace();
}
}
All Above code will save the file as background process.

Android saving file to external storage

I have a little issue with creating a directory and saving a file to it on my android application. I'm using this piece of code to do this :
String filename = "MyApp/MediaTag/MediaTag-"+objectId+".png";
File file = new File(Environment.getExternalStorageDirectory(), filename);
FileOutputStream fos;
fos = new FileOutputStream(file);
fos.write(mediaTagBuffer);
fos.flush();
fos.close();
But it's throwing an exception :
java.io.FileNotFoundException: /mnt/sdcard/MyApp/MediaCard/MediaCard-0.png (No such file or directory)
on that line : fos = new FileOutputStream(file);
If I set the filename to : "MyApp/MediaTag-"+objectId+" it's working, but If I try to create and save the file to an another directory it's throwing the exception. So any ideas what I'm doing wrong?
And another question: Is there any way to make my files private in external storage so user can't see them in gallery, only if he connect his device as Disk Drive?

Use this function to save your bitmap in SD card
private void SaveImage(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
if (!myDir.exists()) {
myDir.mkdirs();
}
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-"+ n +".jpg";
File file = new File (myDir, fname);
if (file.exists ())
file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
and add this in manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
EDIT: By using this line you will be able to see saved images in the gallery view.
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
Uri.parse("file://" + Environment.getExternalStorageDirectory())));
look at this link also http://rajareddypolam.wordpress.com/?p=3&preview=true

The code presented by RajaReddy no longer works for KitKat
This one does (2 changes):
private void saveImageToExternalStorage(Bitmap finalBitmap) {
String root = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
Random generator = new Random();
int n = 10000;
n = generator.nextInt(n);
String fname = "Image-" + n + ".jpg";
File file = new File(myDir, fname);
if (file.exists())
file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
// Tell the media scanner about the new file so that it is
// immediately available to the user.
MediaScannerConnection.scanFile(this, new String[] { file.toString() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("ExternalStorage", "Scanned " + path + ":");
Log.i("ExternalStorage", "-> uri=" + uri);
}
});
}

Update 2018, SDK >= 23.
Now you should also check if the user has granted permission to external storage by using:
public boolean isStoragePermissionGranted() {
String TAG = "Storage Permission";
if (Build.VERSION.SDK_INT >= 23) {
if (this.checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
== PackageManager.PERMISSION_GRANTED) {
Log.v(TAG, "Permission is granted");
return true;
} else {
Log.v(TAG, "Permission is revoked");
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
return false;
}
}
else { //permission is automatically granted on sdk<23 upon installation
Log.v(TAG,"Permission is granted");
return true;
}
}
public void saveImageBitmap(Bitmap image_bitmap, String image_name) {
String root = Environment.getExternalStorageDirectory().toString();
if (isStoragePermissionGranted()) { // check or ask permission
File myDir = new File(root, "/saved_images");
if (!myDir.exists()) {
myDir.mkdirs();
}
String fname = "Image-" + image_name + ".jpg";
File file = new File(myDir, fname);
if (file.exists()) {
file.delete();
}
try {
file.createNewFile(); // if file already exists will do nothing
FileOutputStream out = new FileOutputStream(file);
image_bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
MediaScannerConnection.scanFile(this, new String[]{file.toString()}, new String[]{file.getName()}, null);
}
}
and of course, add in the AndroidManifest.xml:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You need a permission for this
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
and method:
public boolean saveImageOnExternalData(String filePath, byte[] fileData) {
boolean isFileSaved = false;
try {
File f = new File(filePath);
if (f.exists())
f.delete();
f.createNewFile();
FileOutputStream fos = new FileOutputStream(f);
fos.write(fileData);
fos.flush();
fos.close();
isFileSaved = true;
// File Saved
} catch (FileNotFoundException e) {
System.out.println("FileNotFoundException");
e.printStackTrace();
} catch (IOException e) {
System.out.println("IOException");
e.printStackTrace();
}
return isFileSaved;
// File Not Saved
}

Make sure your app has the proper permissions to be allowed to write to external storage: http://developer.android.com/reference/android/Manifest.permission.html#WRITE_EXTERNAL_STORAGE
It should look something like this in your manifest file:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

mediaFile = new File(mediaStorageDir.getPath() + File.separator + mImageName);
return mediaFile;
}

Probably exception is thrown because there is no MediaCard subdir. You should check if all dirs in the path exist.
About visibility of your files: if you put file named .nomedia in your dir you are telling Android that you don't want it to scan it for media files and they will not appear in the gallery.

For API level 23 (Marshmallow) and later, additional to uses-permission in manifest, pop up permission should also be implemented, and user needs to grant it while using the app in run-time.
Below, there is an example to save hello world! as content of myFile.txt file in Test directory inside picture directory.
In the manifest:
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Where you want to create the file:
int permission = ActivityCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
String[] PERMISSIONS_STORAGE = {Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE};
if (permission != PackageManager.PERMISSION_GRANTED)
{
ActivityCompat.requestPermissions(MainActivity.this,PERMISSIONS_STORAGE, 1);
}
File myDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Test");
myDir.mkdirs();
try
{
String FILENAME = "myFile.txt";
File file = new File (myDir, FILENAME);
String string = "hello world!";
FileOutputStream fos = new FileOutputStream(file);
fos.write(string.getBytes());
fos.close();
}
catch (IOException e) {
e.printStackTrace();
}

Old way of saving files might not work with new versions of android, starting with android10.
fun saveMediaToStorage(bitmap: Bitmap) {
//Generating a dummy file name
val filename = "${System.currentTimeMillis()}.jpg"
//Output stream
var fos: OutputStream? = null
//For devices running android >= Q
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
//getting the contentResolver
context?.contentResolver?.also { resolver ->
//Content resolver will process the contentvalues
val contentValues = ContentValues().apply {
//putting file information in content values
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
}
//Inserting the contentValues to contentResolver and getting the Uri
val imageUri: Uri? =
resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
//Opening an outputstream with the Uri that we got
fos = imageUri?.let { resolver.openOutputStream(it) }
}
} else {
//These for devices running on android < Q
//So I don't think an explanation is needed here
val imagesDir =
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
val image = File(imagesDir, filename)
fos = FileOutputStream(image)
}
fos?.use {
//Finally writing the bitmap to the output stream that we opened
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, it)
context?.toast("Saved to Photos")
}
}
Reference- https://www.simplifiedcoding.net/android-save-bitmap-to-gallery/

since android 4.4 file saving has been changed. there is
ContextCompat.getExternalFilesDirs(context, name);
it retuns an array.
when name is null
the first value is like /storage/emulated/0/Android/com.my.package/files
the second value is like
/storage/extSdCard/Android/com.my.package/files
android 4.3 and less it retuns a single item array
parts of little messy code but it demonstrates how it works:
/** Create a File for saving an image or video
* #throws Exception */
private File getOutputMediaFile(int type) throws Exception{
// Check that the SDCard is mounted
File mediaStorageDir;
if(internalstorage.isChecked())
{
mediaStorageDir = new File(getFilesDir().getAbsolutePath() );
}
else
{
File[] dirs=ContextCompat.getExternalFilesDirs(this, null);
mediaStorageDir = new File(dirs[dirs.length>1?1:0].getAbsolutePath() );
}
// Create the storage directory(MyCameraVideo) if it does not exist
if (! mediaStorageDir.exists()){
if (! mediaStorageDir.mkdirs()){
output.setText("Failed to create directory.");
Toast.makeText(this, "Failed to create directory.", Toast.LENGTH_LONG).show();
Log.d("myapp", "Failed to create directory");
return null;
}
}
// Create a media file name
// For unique file name appending current timeStamp with file name
java.util.Date date= new java.util.Date();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",Locale.ENGLISH) .format(date.getTime());
File mediaFile;
if(type == MEDIA_TYPE_VIDEO) {
// For unique video file name appending current timeStamp with file name

}
else if(type == MEDIA_TYPE_AUDIO) {
// For unique video file name appending current timeStamp with file name
mediaFile = new File(mediaStorageDir.getPath() + File.separator + slpid + "_" + pwsid + "_" + timeStamp + ".3gp");
} else {
return null;
}
return mediaFile;
}
/** Create a file Uri for saving an image or video
