I am trying to copy an image that is stored in my application folder to a predefined folder in my gallery.
I started from an image sharing code..
This is my code :
val extension = when (requireNotNull(pictureResult).format) {
PictureFormat.JPEG -> "jpg"
PictureFormat.DNG -> "dng"
else -> throw RuntimeException("Unknown format.")
}
val timestamp = System.currentTimeMillis()
val namePhoto = "picture_" timestamp "." extension;
val destFile = File(filesDir, namePhoto)
val folder = "/CustomFolder"
CameraUtils.writeToFile(requireNotNull(pictureResult?.data), destFile) { file ->
if (file != null) {
// Code to share - it works
/*
val context = this@PicturePreviewActivity
val intent = Intent(Intent.ACTION_SEND)
intent.type = "image/*"
val uri = FileProvider.getUriForFile(context, context.packageName ".provider", file)
intent.putExtra(Intent.EXTRA_STREAM, uri)
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
startActivity(intent)
*/
*/
// Code to save image to gallery - doesn't work :(
val photoDirectory = File(Environment.DIRECTORY_PICTURES folder, namePhoto)
val sourcePath = Paths.get(file.toURI())
Log.i("LOG","sourcePath : " sourcePath.toString()) // /data/user/0/com.app.demo/files/picture_1663772068143.jpg
val targetPath = Paths.get(photoDirectory.toURI())
Log.i("LOG","targetPath : " targetPath.toString()) // /Pictures/CustomFolder/picture_1663772068143.jpg
Files.move(sourcePath, targetPath, StandardCopyOption.REPLACE_EXISTING)
// Error here but I don't know why
} else {
Toast.makeText(this@PicturePreviewActivity, "Error while writing file.", Toast.LENGTH_SHORT).show()
}
}
How do I copy the image to a predefined folder?
CodePudding user response:
Ok, I did it !
Solution :
val folder = "/CustomFolder/" // name of your folder
val timestamp = System.currentTimeMillis()
val namePicture = "picture_" timestamp "." extension;
try {
val path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES folder);
if (!path.exists()) {
path.mkdir();
}
val pathImage = File(path,namePicture)
val stream = FileOutputStream(pathImage)
stream.write(imageByteArray).run {
stream.flush()
stream.close()
}
} catch (e: FileNotFoundException) {
e.printStackTrace()
}
