In Android¶

In Android, you can add the following dependency

implementation("io.github.ydxlt:okdownloader-android:1.0.0")

To add a copy interceptor that records download tasks and prioritizes copying for subsequent downloads of the same resource to prevent duplicate downloads, use the CopyOnExists mechanism:

val downloader = Downloader.Builder()
    .addInterceptor(CopyOnExistsInterceptor(context, 1000))
    .build()

Note: The task records use Google's modern Room database.

To add a network interceptor that supports network restrictions

val downloader = Downloader.Builder()
    .addInterceptor(NetworkInterceptor(context))
    .build()

Afterward, you can set network restrictions

val request = DownloadRequest.Builder()
    .networkOn(DownloadRequest.NETWORK_WIFI or DownloadRequest.NETWORK_DATA)
    .build()

To add a storage interceptor that checks for insufficient disk space and avoids ineffective downloads

val downloader = Downloader.Builder()
    .addInterceptor(StorageInterceptor(100 * 1024 * 1024)) // 100MB
    .build()
