Can anyone help me out..?

Android Save Video To Gallery

I am developing app using camera on fragment,so for camera I have used this library https://natario1.github.io/CameraView/home because I am using watermarks in camera, now I want to save pictures and videos to gallery, for pictures I have done with below code, for video I done research but not get a solution, for pictures this library is giving bitmap so pictures are saving perfectly but for video I can't figure out kindly help me.

Can't save file to SD Card

After following a few tutorials i've got a code to save an created bitmap into the SD Card. However nothing is being saved or created.
I have a method to check if i can write into the External Storage, and it returns true (files \ folders can be created). However when i try to create something it just won't.
I also tried an method just to write an string to the sd card (simple file), didn't worked as well.
Is there any config i should set on Android Studio to save files on the SD Card ?
Important: Using emulated device, no physical device.
I've saw posts on SO\Google about writing to the SD card. They all look like what i'm already doing.
Any input is highly appreciated
Thanks

Android Java copyFile not working for Gallery Image

I have a little camera app that is storing the image to the Pictures folder:
File photo = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "preview.jpg");
Later I want to copy this Image and save it with a new Filename. Therefore i used this copy function i found here:
private void copyFile(File sourceFile, File destFile) throws IOException {
if (!sourceFile.exists()) {
return;
}
FileChannel source = null;
FileChannel destination = null;
source = new FileInputStream(sourceFile).getChannel();
destination = new FileOutputStream(destFile).getChannel();
if (destination != null && source != null) {
destination.transferFrom(source, 0, source.size());
}
if (source != null) {
source.close();
}
if (destination != null) {
destination.close();
}
}
The copyFile is called here:
// OLD FILE
File oldFile = new File(imageUri.getPath());
// NEW FILE
File newFile = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "test123.jpg");
// COPY FILE
copyFile(oldFile,newFile);
But it is doing nothing. Also no Exception or something. What am I doing wrong?

How do I save an image after modifying it

I can load the picture to the background then I have also been able to "sketchify" it but when I try to save it so that I can email it as an attachment I can only figure out haw to grab the original image and what I have here makes the activity close
public void startCamera(View v) {
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
seek.setVisibility(View.GONE);
if (takePicture.resolveActivity(getPackageManager()) != null) {
picSpot = new File(Environment.getExternalStorageDirectory(),
"sketch.png");
outputFileUri = Uri.fromFile(picSpot);
takePicture.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(takePicture, REQUEST_IMAGE_CAPTURE);
}
}
public void sendPic(View v) {
Intent sharePic = new Intent(Intent.ACTION_SEND);
if (didsketch == false) {
sharePic.setType("image/png");
sharePic.putExtra(Intent.EXTRA_STREAM, outputFileUri);
sharePic.putExtra(Intent.EXTRA_SUBJECT, "Check This Out!");
sharePic.putExtra(Intent.EXTRA_TEXT,
"I did this on my Sketchify App!");
startActivity(Intent.createChooser(sharePic, "Send Email"));
} else {
try {
FileOutputStream out = new FileOutputStream(finalSpot);
back.compress(Bitmap.CompressFormat.PNG, 90, out);
out.close();
} catch (Exception e) {
e.printStackTrace();
}
outputFileUri = Uri.fromFile(finalSpot);
sharePic.setType("image/png");
sharePic.putExtra(Intent.EXTRA_STREAM, outputFileUri);
sharePic.putExtra(Intent.EXTRA_SUBJECT, "Check This Out!");
sharePic.putExtra(Intent.EXTRA_TEXT,
"I did this on my Sketchify App!");
startActivity(Intent.createChooser(sharePic, "Send Email"));
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
sketchit.setEnabled(true);
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
DisplayMetrics metrics = this.getResources().getDisplayMetrics();
screenHeight = metrics.heightPixels;
screenWidth = metrics.widthPixels;
location = Environment.getExternalStorageDirectory()
+ "/sketch.png";
back = Camera_Helpers.processImage(location, screenHeight,
screenWidth);
taken = true;
sketchit.setEnabled(taken);
shareit.setEnabled(taken);
image.setImageBitmap(back);
}
}
back is the modified bitmap i am trying to eventually attach to the email
Thanks!!!

Create Folder Directory and Save image into it: create directory where you want to save your images. Suppose the folder name is ImageFolder.
String location = Environment.getExternalStorageDirectory() + "/ImageFolder/";
//Creating Folder Directory
File imageDir = new File(location);
dir.mkdirs();
//Creating Image file
String imageName = "sketch.png";
File imageFile = new File(imageDir, imageName);
//If image file already exists then delete it.
if (imageFile.exists()) {
imageFile.delete();
}
//Writing the image to SDCard
try {
FileOutputStream out = new FileOutputStream(imageFile);
back.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
