Using PRDownloader Library in your Android application

Add this in your build.gradle

implementation 'com.mindorks.android:prdownloader:0.6.0'

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) {
                               
                            }
