zxing-android-embedded VS OkHttp

Yes and no, if you look at https://github.com/journeyapps/zxing-android-embedded for example and its IntentIntegrator, you can also look at the source code itself and get how they use their DecoratedBarcodeView and skip the Activity altogether.

I wrote an app, in french (https://pilldroid.foucry.net, which use the https://github.com/journeyapps/zxing-android-embedded to scan the code of medics.

ZxingDemo uses the ZXing Android Embedded Barcode scanner library for Android, which is based on the ZXing decoder. It is released under the terms of the Apache-2.0 License, and is hosted on GitHub.

We will use Square’s Mock Webserver to spin up a mock server which we can use to simulate real api's request to the get coffee endpoint.

I searched in the OkHttp GitHub project for an advice on which values may be suitable for Android apps nowadays but found no answers (only this old issue which does not help). Since we share a single OkHttp client Singleton for all our retrofit APIs and even Coil, I wonder if the default 5 maxRequestsPerHost is really enough.

You can technically add a Content-Length header for each part. It's not forbidden by the RFC, but nor is it common. It caused [problems](https://github.com/square/okhttp/issues/2138) for OkHttp, and they eventually removed it. Might be fine for internal-only use, though.

Boundaries are a lot like UUIDs, and rely on the same logic. When generating random data, once you have enough bits, the odds are against that sequence of bits ever having been generated before in the universe.

Lets be specific. This is the gradle build file for Squares okhttp client library. How exactly would your bld tool "predict" or "help" with all the parameters needed? There is no need to be defensive. Replace those large build files with your own, show where your approach is better and then understanding will lead to better solutions.

And adding to that: The asynchttpclient library is just a thin wrapper around OkHttp3, so it might be easier to just go with that instead: https://square.github.io/okhttp/

Retrofit in combination with OkHttp for fetching data from server (which hopefully already exists)
