Android Snooper is a HTTP inspector which observes all the HTTP calls made by the app and opens up an Activity to see the detailed history of HTTP calls on onShake event. This library is inspired by the Network Request History feature of FLEX app for iOS. Android Snooper works on the interceptor mechanism provided by almost every HTTP client. https://github.com/jainsahab/AndroidSnooper

Android Snooper is a library which helps in debugging issues while running the applications on android devices. One of the basic features provided includes HTTP inspection, which observes all the HTTP calls made by the app. When the device is shaked, history of all the HTTP requests is presented with their responses and allows search, copy and sharing of the request/response. This library is inspired by the Network Request History feature of FLEX app for iOS.


How to use?

Android Snooper works on the interceptor pattern which is supported by almost every HTTP client. All you need to do is initialize Android Snooper using AndroidSnooper.init(this); statement in your Application class and set an instance of SnooperInterceptor to the list of your network interceptors. As of now Snooper supports the interceptors for the following libraries:

Didn't get your HTTP client's name in the list? No worries, You can still write your own implementation by using Android Snooper's core module and let Android Snooper know about the request being made. Below is given a dummy implementation.

    AndroidSnooper androidSnooper = AndroidSnooper.getInstance();
    HttpCall httpCall = new HttpCall.Builder()

The above implementation ought to be part of your custom interceptor where you will have access to the required Request and Response object to jot down the required data for Android Snooper to work properly.

Warning: Android Snooper records each and every HTTP call intercepted by it. The sole purpose of Android snooper is to help in debugging, hence only Debug or QA builds are the perfect candidates for integrating the library. Sensitive information such as Auth Tokens, Headers, etc are not supposed to be exposed and hence production apps should not integrate the library.
