But in large projects this approach cannot be worked, where it is hard to keep track of what needs to be built, in which sequence and what dependencies are there in the building process. When only two or three files are there this approach worked. In small projects, developers can manually create the build process. You can create your own build system based using shell scripting in Linux and using a batch file in windows. To automate these all tasks we use scripts. That’s why android is so strict about naming the directories. While generating APK, whenever build system needs any resource, It is designed in such a way that it finds that resource in a res directory. The build system uses some naming convention, they design in such a way that they perform their operations based on that naming convention. Why every resource goes into a res directory, why layouts must go into layout the directory, that is because of these build systems. kt files) and generate an executable package or APK.Įver you asked yourself why android is so strict for naming the folders. xml), then applies appropriate compilation process (like use kotlin compiler for compiling.

In Android, Build system takes all the source files (like.

packing that executable code and generate APK or executable form.

Compiling source code into executable code.

Build process incorporates compiling, linking, and packaging the code into executable form.īuild tools used to automates tedious tasks like: But before understanding Gradle, we need to understand what is build tool and why we need one.īuild tool is a software that helps to automates the process of application creation.
