I have already succeeded with this operation with images, but I cannot do it with other type of file, in my case I try to insert a database.
Here is an example of the code for the images:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q){
try {
try {
pictures = assetManager.list("photos/dataset1");
} catch (IOException e) {
Log.e("tag", "Failed to get asset file list.", e);
}
if (pictures != null) {
for (String filename : pictures) {
InputStream in;
OutputStream out;
InputStream inputStream = assetManager.open("photos/dataset1/"+filename);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
saveImageToGallery(bitmap);
}
}
} catch (IOException e) {
e.printStackTrace();
}
}
This method below works for the images :
public void saveImageToGallery(Bitmap bitmap) {
OutputStream outputStream;
Context myContext = requireContext();
try {
if(Build.VERSION.SDK_INT >=Build.VERSION_CODES.Q){
ContentResolver contentResolver = requireContext().getContentResolver();
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME,"Image_"+".jpg");
contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES);
Uri imageUri = contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
outputStream = contentResolver.openOutputStream(Objects.requireNonNull(imageUri));
bitmap.compress(Bitmap.CompressFormat.JPEG,100, outputStream);
Objects.requireNonNull(outputStream);
}
}catch (FileNotFoundException e) {
e.printStackTrace();
}
}
and there my try for the other type of file :
if (files!= null) {
for (String filename : files) {
InputStream in;
OutputStream out;
try {
in = assetManager.open("database/test/" + filename);
File outFile = new File(databasesFolder, filename);
out = new FileOutputStream(outFile);
copyFile(in, out);
in.close();
out.flush();
out.close();
} catch (IOException e) {
Log.e("tag", "Failed to copy asset file: " + filename, e);
}
}
} else {
Log.e("Error NPE", "files is null");
}
private void copyFile(InputStream in, OutputStream out) throws IOException {
byte[] buffer = new byte[1024];
int read;
while ((read = in.read(buffer)) != -1) {
out.write(buffer, 0, read);
}
}
This function above is not working, I want something like this or a function similary as the function for my images but for any type of file. When I run my application I have no error however nothing happens
