Gson converter, the same concept can be used with most of the other supported ones as well.
Imagine you’re in a situation where your backend can return a
JSON response that’s dynamic in nature, a.k.a some parts of it don’t adhere to a specific pre-defined schema. Say you retrieve information about a webpage that you need to open in a
WebView. You need to support both
POST HTTP requests, so two valid responses are:
Here’s a few handy commands if you want to run only a specific unit test(s). Suppose we have the following unit tests in the project:
./gradlew test – run unit tests for all variants
./gradlew testDebug – run tests for Debug variant
./gradlew testDebug --tests="*.helpers.*" – run all tests in the
./gradlew testDebug --tests="*.HelperTest" – run all tests in
./gradlew testDebug --tests="*.getHelp" – run only the
getHelp test method.
Today I took up a 60 day running challenge. It’s super simple – I need to run 60 consecutive days to succeed. I took up the challenge mainly for 2 reasons:
- To give myself a lesson in persistence, which I truly believe is the most important factor to success in any field or undertaking.

- Fun – experienced runners say running can be fun. Currently I don’t see how this can be true, but let’s put it to the test.
Well today I did get to Primrose Hill and backwards, so let’s say run 00 to be completed.
This post will list some of my favourite features of a Proxy tool that are used on a daily bases in my team. It’s about giving you the overview of how such a tool will help you be more efficient in your day-to-day development process. It won’t get into details of how to setup a proxy, how to use these features or which specific tool to use – this will be covered in a future post.
Let’s get to it!
With the release of Android M (API 23) the Support library got a major update as well. One of the unsung heroes is a feature badly requested since Android’s early days – the ability to set dimensions in percentages. With the release of the Percent Support Library is’t now possible to set a
View to take exactly 30% of the screen, or to set it’s
marginTop to 10% for example.
As an Android developer you should certainly know what overdraw is and why it’s bad. If not – THIS episode of Android Performance Patterns got you covered, check it out.
Finding overdraw is super easy – you can do it right on your device:
As an assistant of a course in basic Java in my local university, I saw a common misunderstanding among students what interfaces really are. In this short article I’ll try to give students another point of view.
As we all know “an interface is a group of related methods with empty bodies”*. Consider the following example:
