Android Utility belt β€” Collection of dependencies for a greenfield project

Starting an android project will bring in a new set of challenges πŸ‘€ aka adding tons of Gradle dependencies.

Even though you use these dependencies in almost all your applications, you can't just grab them from the previous project because it might be an outdated version. By the time you find the latest version and add it to the project, you'd lose half the energy. Coming to the point!!

…

In this post, I composed a list of dependencies that I use in most of my projects. They're at the latest version when I write it(Oct 2021). For convenience, hyperlinked the maven central page so that picking the latest version is just a click away.

I highly recommend using this template project for greenfield projects. From DI/logger to instrumentation test everything has been perfectly set up. Though, the network dependencies are not present in the template. So, look up below and add dependencies as you see fit.

…

Network

OkHttp3

implementation(platform("com.squareup.okhttp3:okhttp-bom:4.9.2"))
implementation("com.squareup.okhttp3:okhttp")
implementation("com.squareup.okhttp3:logging-interceptor")

or

implementation 'com.squareup.okhttp3:logging-interceptor:4.9.2'
testImplementation("com.squareup.okhttp3:mockwebserver:4.9.2")
