How do I use File Loader?

Asynchronously load file as generic file:

FileLoader.with(this)
 .load("https://upload.wikimedia.org/wikipedia/commons/3/3c/Enrique_Simonet_-_Marina_veneciana_6MB.jpg",false) //2nd parameter is optioal, pass true to force load from network
 .fromDirectory("test4", FileLoader.DIR_INTERNAL)
 .asFile(new FileRequestListener<File>() {
 @Override
 public void onLoad(FileLoadRequest request, FileResponse<File> response) {
 File loadedFile = response.getBody();
 // do something with the file
 }
 @Override
 public void onError(FileLoadRequest request, Throwable t) {
 }
 });

Load file as Object:

FileLoader.with(this)
 .load("http://echo.jsontest.com/key1/value1/key2/value2")
 .fromDirectory("test3", FileLoader.DIR_INTERNAL)
 .asObject(new FileRequestListener<JsonTest>() {
 @Override
 public void onLoad(FileLoadRequest request, FileResponse<JsonTest> response) {
 JsonTest jsonTest = response.getBody();
 //do something with jsonTest object
 }
 @Override
 public void onError(FileLoadRequest request, Throwable t) {
 }
 });

Load multiple files with progress update listener ( load all from same directory ):

final String[] uris = {"https://images.pexels.com/photos/45170/kittens-cat-cat-puppy-rush-45170.jpeg",
 "https://upload.wikimedia.org/wikipedia/commons/3/3c/Enrique_Simonet_-_Marina_veneciana_6MB.jpg",
 "https://d15shllkswkct0.cloudfront.net/wp-content/blogs.dir/1/files/2017/01/Google-acquires-Fabric.png"};
 
FileLoader.multiFileDownload(this)
 .fromDirectory(Environment.DIRECTORY_PICTURES, FileLoader.DIR_EXTERNAL_PUBLIC)
 .progressListener(new MultiFileDownloadListener() {
 @Override
 public void onProgress(File downloadedFile, int progress, int totalFiles) {
 }
 @Override
 public void onError(Exception e, int progress) {
 super.onError(e, progress);
 }
 }).loadMultiple(uris);

Load multiple files with progress update listener ( load from different directory ):

List<MultiFileLoadRequest> multiFileLoadRequests = new ArrayList<>();
 multiFileLoadRequests.add(new MultiFileLoadRequest(uris[0], "test2", FileLoader.DIR_INTERNAL, false));
 multiFileLoadRequests.add(new MultiFileLoadRequest(uris[1], Environment.DIRECTORY_DOWNLOADS, FileLoader.DIR_EXTERNAL_PRIVATE, false));
 multiFileLoadRequests.add(new MultiFileLoadRequest(uris[2], Environment.DIRECTORY_PICTURES, FileLoader.DIR_EXTERNAL_PUBLIC, false));
 
MultiFileDownloader multiFileDownloader = FileLoader.multiFileDownload(this);
multiFileDownloader.progressListener(new MultiFileDownloadListener() {
 @Override
 public void onProgress(File downloadedFile, int progress, int totalFiles) {
 
 }
 @Override
 public void onError(Exception e, int progress) {
 super.onError(e, progress);
 }
 }).loadMultiple(true, uris);

Cancel the Multiple loading:

multiFileDownloader.cancelLoad();

Delete multiple files:

final String[] uris = {"https://images.pexels.com/photos/45170/kittens-cat-cat-puppy-rush-45170.jpeg",
 "https://upload.wikimedia.org/wikipedia/commons/3/3c/Enrique_Simonet_-_Marina_veneciana_6MB.jpg",
 "https://d15shllkswkct0.cloudfront.net/wp-content/blogs.dir/1/files/2017/01/Google-acquires-Fabric.png"};
try {
 FileLoader.deleteWith(this).fromDirectory("test2", FileLoader.DIR_INTERNAL).deleteFiles(uris);
 } catch (Exception e) {
 e.printStackTrace();
 }

Delete all files of the directory:

FileLoader.deleteWith(this).fromDirectory("test2", FileLoader.DIR_INTERNAL).deleteAllFiles();

Delete all files of directory except files passed in argument:

FileLoader.deleteWith(this).fromDirectory("test3", FileLoader.DIR_INTERNAL).deleteAllFilesExcept(uris);

Status

Cheers :)
