PRDownloader — A File Downloader Library For Android

PRDownloader: A file downloader library for Android with pause and resume support.

I recently published a library, which I believe to be the simplest way to handle downloading in Android with pause and resume support.

Overview of PRDownloader library:

This file downloader library can be used to download any type of files like image, video, pdf, apk and etc.
This file downloader library supports pause and resumes while downloading a file.
Supports large file downloads.
This downloader library has a simple interface to make a download request.
We can check if the status of downloading with the given download Id.
PRDownloader gives callbacks for everything like onProgress, onCancel, onStart, onError and etc while downloading a file.
Supports proper request canceling.
Many requests can be made in parallel.
All types of customization are possible.

How to use the PRDownloader library?

Using PRDownloader Library in your Android application

Add this in your build.gradle

compile 'com.mindorks.android:prdownloader:0.3.0'

Do not forget to add internet permission in manifest if already not present:

<uses-permission android:name="android.permission.INTERNET" />

Then initialize it in onCreate() Method of application class :

PRDownloader.initialize(getApplicationContext());

Initializing it with some customization

// Enabling database for resume support even after the application is killed:
PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
                .setDatabaseEnabled(true)
                .build();
PRDownloader.initialize(getApplicationContext(), config);

// Setting timeout globally for the download network requests:
PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
                .setReadTimeout(30_000)
                .setConnectTimeout(30_000)
                .build();
PRDownloader.initialize(getApplicationContext(), config);

Make a download request:

int downloadId = PRDownloader.download(url, dirPath, fileName)
                        .build()
                        .setOnStartOrResumeListener(new OnStartOrResumeListener() {
                            @Override
                            public void onStartOrResume() {
                               
                            }
                        })
                        .setOnPauseListener(new OnPauseListener() {
                            @Override
                            public void onPause() {
                               
                            }
                        })
                        .setOnCancelListener(new OnCancelListener() {
                            @Override
                            public void onCancel() {
                                
                            }
                        })
                        .setOnProgressListener(new OnProgressListener() {
                            @Override
                            public void onProgress(Progress progress) {
                               
                            }
                        })
                        .start(new OnDownloadListener() {
                            @Override
                            public void onDownloadComplete() {
                               
                            }

                            @Override
                            public void onError(Error error) {
                               
                            }
                        });

Pause a download request

PRDownloader.pause(downloadId);

Resume a download request

PRDownloader.resume(downloadId);

Cancel a download request

// Cancel with the download id
PRDownloader.cancel(downloadId);
// The tag can be set to any request and then can be used to cancel the request
PRDownloader.cancel(TAG);
// Cancel all the requests
PRDownloader.cancelAll();

Status of a download request

Status status = PRDownloader.getStatus(downloadId);

Clean up resumed files if database enabled

// Method to clean up temporary resumed files which is older than the given day
PRDownloader.cleanUp(days);

Recently, we added this library to our Android App at CuriousJr.
