How Google's Android protection changes runtime analysis.
ReadFull Android APK to API service
Send the APK. Get every API, protection mechanism and backend workflow in Python, JavaScript/TypeScript, Postman and complete API documentation.
We rebuild the full Android app as working Python, JavaScript/TypeScript, Postman and API documentation. Authentication, signature generation, encryption, decryption, sessions and request sequencing are included.

24–72 hour delivery. We reply within one hour. 30 days of defect fixes included.
Output
The app does something.
You need to do it programmatically.
In the application
As an interface
result = client.lookup("ABC123")
Fig. 02 · the same behavior, reproduced outside the UI
We reverse the full Android app and deliver its complete callable API in Python, JavaScript/TypeScript and Postman. Authentication, signatures, encryption, sessions and request workflows are included.

A captured endpoint is sometimes enough. Frequently it isn't. Reproducing a function may depend on state, dynamically generated values, native logic or protections that only become visible while the application is running.
How it works
From application to callable implementation
01
Send the application
Play Store URL, application name or APK.
02
Review the full APK
We identify every endpoint, workflow, protection layer and runtime dependency.
03
Trace the implementation
Inspect the relevant static code, runtime behavior, network flows, native components and protections.
04
Reconstruct the dependencies
Authentication, sequencing, signatures, encryption, protocols or other required behavior.
05
Build every format
We build Python, JavaScript/TypeScript, Postman and complete API documentation for the same full application.
06
Verify it
Test every endpoint, workflow and generated value across the full API package.
07
Handover
Deliver code, requests, documentation and relevant implementation notes.
Protected applications
Protected APKs are still analyzable.
Protection raises the cost of a reconstruction. It does not remove the behavior. These are the classes of difficulty we routinely work through.
- Code obfuscation
- Control-flow obfuscation
- String encryption
- Runtime code loading
- Virtualization
- Anti-debugging
- Anti-hooking
- Root detection
- Emulator detection
- Integrity checking
- Signature verification
- Native protection
- Encrypted assets
- Dynamic code

Start a project
Send the full APK
Send the full APK. We review the application and quote its complete API reconstruction.
One full APK. One complete delivery.
Projects start at $120. Most are delivered in 24 to 72 hours.
Every format included
Python, JavaScript/TypeScript, Postman and complete API documentation cover the same full endpoint set. Your team runs the clients in its own server or system.
Ready in 24–72 hours
The 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.
Deployment checked before the quote
The package includes signing, encryption, decryption and session handling. We verify device-bound keys and server integrity checks during review and document runtime requirements before you commit.
30 days of fixes
Report a defect within 30 days of delivery. We fix any delivered call that does not match the tested APK at no extra cost.
Before you send the APK
What your team needs to know
Send the full APK through WhatsApp or email. We reply within one hour.
What does the delivery include?
Every endpoint, protection mechanism and backend workflow in the APK, delivered as Python, JavaScript/TypeScript, Postman and complete API documentation.
How long does it take?
The 24–72 hour clock starts when we receive the APK and any account access the app requires. Most projects finish sooner. Your fixed quote confirms the deadline.
Where does the finished API run?
It runs on your server or inside your system. We include setup instructions and review the deployment with your team.
Will the finished API need Android?
We check this during review. Software-generated values run in the clients. Hardware-backed keys and server-required integrity proofs have device dependencies; the quote states the deployment requirements.
What happens if a delivered call fails?
Report it within 30 days of delivery. We fix any delivered call that does not match the tested APK at no extra cost.
