Keterangan

Pengembang dapat melampirkan handler ke konten web pramuat dan cache sehingga aplikasi dapat diluncurkan dan kontennya di-refresh dan diperbarui. Mengakses konten yang di-cache membantu mengurangi waktu aktivasi aplikasi dengan tidak harus mengantre permintaan web yang mahal.

Selain tugas kustom, ContentPrefetcher API yang ada masih tersedia dan dapat digunakan alih-alih tugas kustom ketika pekerjaan prasyarat hanya melibatkan pramuat dan penembolokan konten dari sekumpulan URI tetap atau dinamis.
