download-manager

A library that handles long-running downloads, handling the network interactions and retrying downloads automatically after failures. Clients can request downloads in batches, receiving a single notification for all of the files allocated to a batch while being able to retrieve the single files after downloads complete.

Adding to your project

To start using this library, add these lines to the build.gradle of your project:

repositories {
    jcenter()
}

dependencies {
    compile 'com.novoda:download-manager:<latest-version>'
}

Simple usage

1. Create a DownloadManager:

DownloadManager downloadManager = DownloadManagerBuilder
        .newInstance(this, handler, R.mipmap.ic_launcher_round)
        .withLogHandle(new DemoLogHandle())
        .withStorageRequirementRules(StorageRequirementRuleFactory.createByteBasedRule(TWO_HUNDRED_MB_IN_BYTES))
        .build();

2. Create a Batch of files to download:

Batch batch = Batch.with(primaryStorageWithDownloadsSubpackage, DownloadBatchIdCreator.createSanitizedFrom("batch_id_1"), "batch one title")
        .downloadFrom("http://ipv4.download.thinkbroadband.com/5MB.zip").saveTo("foo/bar", "local-filename-5mb.zip").withIdentifier(DownloadFileIdCreator.createFrom("file_id_1")).apply()
        .downloadFrom("http://ipv4.download.thinkbroadband.com/10MB.zip").apply()
        .build();

3. Schedule the batch for download:

downloadManager.download(batch);

Snapshots

Snapshot builds from develop are automatically deployed to a repository that is not synced with JCenter. To consume a snapshot build add an additional maven repo as follows:

repositories {
    maven {
        url 'https://dl.bintray.com/novoda-oss/snapshots/'
    }
}

You can find the latest snapshot version following this link.
