Answer 1

These are Gradle build tasks. Gradle is the build automation system of Android Studio and it has set of tasks to perform in order to build apk. Each time you run/build project it goes through these list of tasks one after another. Build time depends on your project code and dependencies you used in your project.

Gradle Build Life Cycle

Gradle is a language for dependency based programming. In Gradle terms this means that you can define tasks and dependencies between tasks. Gradle guarantees that these tasks are executed in the order of their dependencies, and that each task is executed only once. These tasks form a Directed Acyclic Graph. There are build tools that build up such a dependency graph as they execute their tasks. Gradle builds the complete dependency graph before any task is executed.

It is the Gradle build life cycle. It has three phases

*) Initialization

*) Configuration

*) Execution

You may try to add the following code to your gradle.properties file:

org.gradle.jvmargs=-Xmx5124m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
org.gradle.daemon=true
org.gradle.configureondemand=true
org.gradle.parallel=true

This may help speed up your gradle build.
