Android Extract API

A focused use case

Process an approved file chosen by a user, then show a reviewable result without scanning unrelated device storage.

A practical workflow

Choose the storage and sharing mechanism that matches the task. Preserve the user-selected scope, account for interrupted jobs, and separate temporary files from retained records with a clear cleanup policy.

An example record contract

These fields illustrate the decisions to make before implementation. Adapt the names and required values to the receiving system; the table is not a promise of a live endpoint or a provider-specific response.

Limits worth keeping visible

Android storage options have different access boundaries. Do not treat a file selection as permission to inventory the whole device or another app’s private data.

Before increasing the workload

Run a small, authorized test set through the whole path, including the receiving application. Keep accepted, rejected, and incomplete outcomes distinguishable. A result should retain the context needed to explain its meaning after it leaves the extractor.
