How to create a video file path on Android 10

How to create a video file path on Android 10 - java

I tried to create a video file path as the follows :
String fileName = videoFileName = "VID" + System.currentTimeMillis() + ".mp4";
public static String createVideoPath(Context context, String fileName) {
File imageThumbsDirectory = context.getExternalFilesDir("FOLDER");
if (imageThumbsDirectory != null) {
if (!imageThumbsDirectory.exists()) {
imageThumbsDirectory.mkdir();
}
}
String appDir = context.getExternalFilesDir("FOLDER").getAbsolutePath();
File file = new File(appDir, fileName);
return file.getAbsolutePath();
}
I call the method above like this : String videoPath = createVideoPath(getApplicationContext(),fileName);
I use this library for edits :
EZFilter.input(mainBitmap).addFilter(null).enableRecord(videoPath, true, false).into(renderView);
After the edit finished, I try to save the final video to the gallery as follows :
private static Uri publicDirURI(Context context, String fileName, String dir) {
ContentValues valuesVideos;
valuesVideos = new ContentValues();
valuesVideos.put(MediaStore.Video.Media.RELATIVE_PATH, dir);
valuesVideos.put(MediaStore.Video.Media.TITLE, fileName);
valuesVideos.put(MediaStore.Video.Media.DISPLAY_NAME, fileName);
valuesVideos.put(MediaStore.Video.Media.MIME_TYPE, "video/mp4");
valuesVideos.put(MediaStore.Video.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
valuesVideos.put(MediaStore.Video.Media.DATE_TAKEN, System.currentTimeMillis());
valuesVideos.put(MediaStore.Video.Media.IS_PENDING, 1);
ContentResolver resolver = context.getContentResolver();
Uri collection = MediaStore.Video.Media.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);
Uri uriSavedVideo = resolver.insert(collection, valuesVideos);
return saveFileToPublicMovies(context, valuesVideos, uriSavedVideo, fileName);
}
private static Uri saveFileToPublicMovies(Context context, ContentValues contentValues, Uri uriSavedVideo, String fileName) {
ParcelFileDescriptor pfd;
try {
pfd = context.getContentResolver().openFileDescriptor(uriSavedVideo, "w");
FileOutputStream out = null;
if (pfd != null) {
out = new FileOutputStream(pfd.getFileDescriptor());
File videoFile = new File(context.getExternalFilesDir("FOLDER"), fileName);
FileInputStream in = new FileInputStream(videoFile);
byte[] buf = new byte[8192];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
out.close();
in.close();
pfd.close();
}
} catch (Exception e) {
e.printStackTrace();
}
contentValues.clear();
contentValues.put(MediaStore.Video.Media.IS_PENDING, 0);
context.getContentResolver().update(uriSavedVideo, contentValues, null, null);
return uriSavedVideo;
}
But I always get an empty saved video with 0.00b, I've tried the app with device running Android 9, but with getExternalStoragePublicDirectory, and everyting works just fine, so the issue is not related with the library.
Could anyone help me to solve this issue, I'm stuck on it almost 1 week, thank you
Edit :
private static Uri saveFileToPublicMovies(Context context, ContentValues contentValues, Uri uriSavedVideo, String fileName) {
ParcelFileDescriptor pfd;
try {
pfd = context.getContentResolver().openFileDescriptor(uriSavedVideo, "w");
FileOutputStream out = null;
if (pfd != null) {
out = new FileOutputStream(pfd.getFileDescriptor());
File videoFile = new File(context.getExternalFilesDir("AppName"), fileName);
FileInputStream in = new FileInputStream(videoFile);
byte[] buf = new byte[8192];
int len;
while ((len = in.read(buf)) > 0) {
out.write(buf, 0, len);
}
out.flush();
out.getFD().sync();
out.close();
in.close();
pfd.close();
}
} catch (Exception e) {
e.printStackTrace();
}
contentValues.clear();
contentValues.put(MediaStore.Video.Media.IS_PENDING, 0);
context.getContentResolver().update(uriSavedVideo, contentValues, null, null);

how to save bitmap to android gallery

unfortunately the solutions I've found didn't work on android 5.1.1.
I have a bitmap called source. I need to save it directly to my phone's gallery. My manifest contains <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
Can you give me a working method to do this?

There were several different ways to do it before API 29 (Android Q) but all of them involved one or a few APIs that are deprecated with Q. In 2019, here's a way to do it that is both backward and forward compatible:
(And since it is 2019 so I will write in Kotlin)
/// #param folderName can be your app's name
private fun saveImage(bitmap: Bitmap, context: Context, folderName: String) {
if (android.os.Build.VERSION.SDK_INT >= 29) {
val values = contentValues()
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + folderName)
values.put(MediaStore.Images.Media.IS_PENDING, true)
// RELATIVE_PATH and IS_PENDING are introduced in API 29.
val uri: Uri? = context.contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)
if (uri != null) {
saveImageToStream(bitmap, context.contentResolver.openOutputStream(uri))
values.put(MediaStore.Images.Media.IS_PENDING, false)
context.contentResolver.update(uri, values, null, null)
}
} else {
val directory = File(Environment.getExternalStorageDirectory().toString() + separator + folderName)
// getExternalStorageDirectory is deprecated in API 29
if (!directory.exists()) {
directory.mkdirs()
}
val fileName = System.currentTimeMillis().toString() + ".png"
val file = File(directory, fileName)
saveImageToStream(bitmap, FileOutputStream(file))
if (file.absolutePath != null) {
val values = contentValues()
values.put(MediaStore.Images.Media.DATA, file.absolutePath)
// .DATA is deprecated in API 29
context.contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values)
}
}
}
private fun contentValues() : ContentValues {
val values = ContentValues()
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png")
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
return values
}
private fun saveImageToStream(bitmap: Bitmap, outputStream: OutputStream?) {
if (outputStream != null) {
try {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream)
outputStream.close()
} catch (e: Exception) {
e.printStackTrace()
}
}
}
Also, before calling this, you need to have WRITE_EXTERNAL_STORAGE first.

Use this one:
private void saveImage(Bitmap finalBitmap, String image_name) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root);
myDir.mkdirs();
String fname = "Image-" + image_name+ ".jpg";
File file = new File(myDir, fname);
if (file.exists()) file.delete();
Log.i("LOAD", root + fname);
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}

Use this code this we help you to store images into a particular folder which is saved_images and that folder images show in gallery immediately.
private void SaveImage(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);
// sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED,
// Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
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);
}
});
}

From Android Q there are changes in saving image to gallery.Thanks to #BaoLei, here is my answer in java if anybody needs it.
private void saveImage(Bitmap bitmap) {
if (android.os.Build.VERSION.SDK_INT >= 29) {
ContentValues values = contentValues();
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + getString(R.string.app_name));
values.put(MediaStore.Images.Media.IS_PENDING, true);
Uri uri = this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
if (uri != null) {
try {
saveImageToStream(bitmap, this.getContentResolver().openOutputStream(uri));
values.put(MediaStore.Images.Media.IS_PENDING, false);
this.getContentResolver().update(uri, values, null, null);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
} else {
File directory = new File(Environment.getExternalStorageDirectory().toString() + '/' + getString(R.string.app_name));
if (!directory.exists()) {
directory.mkdirs();
}
String fileName = System.currentTimeMillis() + ".png";
File file = new File(directory, fileName);
try {
saveImageToStream(bitmap, new FileOutputStream(file));
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
this.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}
private ContentValues contentValues() {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png");
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
}
return values;
}
private void saveImageToStream(Bitmap bitmap, OutputStream outputStream) {
if (outputStream != null) {
try {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}

Here is a fully working solution in Kotlin:
fun saveToGallery(context: Context, bitmap: Bitmap, albumName: String) {
val filename = "${System.currentTimeMillis()}.png"
val write: (OutputStream) -> Boolean = {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, it)
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/png")
put(MediaStore.MediaColumns.RELATIVE_PATH, "${Environment.DIRECTORY_DCIM}/$albumName")
}
context.contentResolver.let {
it.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)?.let { uri ->
it.openOutputStream(uri)?.let(write)
}
}
} else {
val imagesDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM).toString() + File.separator + albumName
val file = File(imagesDir)
if (!file.exists()) {
file.mkdir()
}
val image = File(imagesDir, filename)
write(FileOutputStream(image))
}
}

Do it in One Line
MediaStore.Images.Media.insertImage(applicationContext.getContentResolver(), IMAGE ,"nameofimage" , "description");

Now we have android10 and android11, so here is an updated version, that will work in all android devices.
Make sure you have the WRITE_EXTERNAL_STORAGE permission before calling this function.
private fun saveMediaToStorage(bitmap: Bitmap) {
val filename = "${System.currentTimeMillis()}.jpg"
var fos: OutputStream? = null
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
contentResolver?.also { resolver ->
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, filename)
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES)
}
val imageUri: Uri? =
resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
fos = imageUri?.let { resolver.openOutputStream(it) }
}
} else {
val imagesDir =
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
val image = File(imagesDir, filename)
fos = FileOutputStream(image)
}
fos?.use {
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, it)
toast("Saved to Photos")
}
}
Its kotlin, and I think very straight forward and self explaining code. But still if you have a problem, comment below and I will explain.
Reference: Android Save Bitmap to Gallery Tutorial.

I'd like to add Java code based on #Bao Lei 's answer that I used in my app.
private void saveImage(Bitmap bitmap, Context context, String folderName) throws FileNotFoundException {
if (android.os.Build.VERSION.SDK_INT >= 29) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.RELATIVE_PATH, "Pictures/" + folderName);
values.put(MediaStore.Images.Media.IS_PENDING, true);
// RELATIVE_PATH and IS_PENDING are introduced in API 29.
Uri uri = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
if (uri != null) {
saveImageToStream(bitmap, context.getContentResolver().openOutputStream(uri));
values.put(MediaStore.Images.Media.IS_PENDING, false);
context.getContentResolver().update(uri, values, null, null);
}
} else {
dir = new File(getApplicationContext().getExternalFilesDir(Environment.DIRECTORY_PICTURES),"");
// getExternalStorageDirectory is deprecated in API 29
if (!dir.exists()) {
dir.mkdirs();
}
java.util.Date date = new java.util.Date();
imageFile = new File(dir.getAbsolutePath()
+ File.separator
+ new Timestamp(date.getTime()).toString()
+ "Image.jpg");
imageFile = new File(dir.getAbsolutePath()
+ File.separator
+ new Timestamp(date.getTime()).toString()
+ "Image.jpg");
saveImageToStream(bitmap, new FileOutputStream(imageFile));
if (imageFile.getAbsolutePath() != null) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATA, imageFile.getAbsolutePath());
// .DATA is deprecated in API 29
context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
}
}
}
private ContentValues contentValues() {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.MIME_TYPE, "image/png");
values.put(MediaStore.Images.Media.DATE_ADDED, System.currentTimeMillis() / 1000);
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
return values;
}
private void saveImageToStream(Bitmap bitmap, OutputStream outputStream) {
if (outputStream != null) {
try {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream);
outputStream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This one worked fine in my app.

For Media Scanning, you can simply do
val intent = Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE)
intent.data = Uri.fromFile(path) // path must be of File type
context.sendBroadcast(intent)

Copy file from assets to folder on the sdcard fails

I am using tesseract OCR in my app (Spl!t). When I launch the app from Eclipse to my phone, eng.traineddata is copied into /storage/emulated/0/Pictures/Receipts/tessdata/.
