Turn the full APK into a complete callable API

The full application is the scope

We map every endpoint and background request in the APK. This includes login, token refresh, request order, generated headers, uploads, downloads and error paths. Java, Kotlin, Flutter, React Native and JNI are followed wherever request data moves.

Protected code stays part of the same project. We record which checks stop the app, which values reach the backend and which keys are tied to Android hardware. Runtime needs are stated before the fixed quote.

Run the complete demonstration

The public package has one local API and matching Python, TypeScript and Postman clients. Each version logs in, rotates a refresh token, encrypts a body with AES-256-GCM, signs the exact bytes with HMAC-SHA-256, parses the result and confirms that a bad signature is rejected.

Read the walkthrough and download every file. It is synthetic and contains no customer APK, secret or production traffic.

What you receive

• Python and JavaScript/TypeScript clients covering the same full endpoint set.
• An importable Postman collection with environments, scripts and response tests.
• API documentation for methods, models, authentication, request state and errors.
• Tests for generated values, token expiry, repeated calls and failed requests.

Your team runs the delivered clients in its own server, worker, script or internal system. SReverse does not host the standard delivery as a shared HTTP service.

How verification works

A formatted JSON object can differ from the bytes an app signs. We preserve the method, path, query order, headers and raw body sent by the app. Tests use fixed inputs to compare signatures, encryption and serialization. Session tests start at login and complete the same request order used by the APK.

Android Keystore keys can be non-exportable and bound to secure hardware. A server that requires proof from that hardware has a runtime dependency that copied code cannot remove. We check this during the APK review and state the deployment requirements before the quote. Android Keystore documentation.

The full APK is the project

You receive Python, JavaScript/TypeScript, Postman and API documentation for the full application. The work covers endpoints, authentication, request signatures, encryption, decryption, sessions and backend workflows.

Run the complete public demonstration to inspect one matching workflow in every format.

Send the APK on WhatsApp or email. The 24–72 hour delivery window starts after we receive the APK and any account access needed to run it. The fixed quote states the deadline. Most projects finish sooner.
