How do you use gradle in Android?

In Android development, Gradle is a build tool used for compiling, packaging, and managing project dependencies. Here are some common methods for using Gradle:

Specify the Gradle version in the `build.gradle` file located in the project’s root directory. For example:

   buildscript {
       repositories {
           google()
           jcenter()
       }
       dependencies {
           classpath 'com.android.tools.build:gradle:4.2.0'
       }
   }

2. Adding dependencies: In the `build.gradle` file of the module, dependencies required for the project can be added using the `dependencies` block. For example:

   dependencies {
       implementation 'com.google.android.material:material:1.3.0'
       implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.3.1'
       testImplementation 'junit:junit:4.13.2'
   }

3. Custom Build Configuration: You can define your own build configuration in the `build.gradle` file. For example, you can modify the compile version, application ID, and signature configuration. These configurations can be adjusted according to your project’s requirements.

Building tasks: Gradle offers a variety of predefined building tasks, such as compiling code, running unit tests, and generating APKs. These tasks can be executed using the command line or the Gradle tool window in Android Studio.

Multiple Modules Project: If your project has multiple modules, you can use Gradle for managing dependencies between modules. You can specify the dependency relationships in the `build.gradle` file of each module.

These are just some basic uses of Gradle, you can further learn and use other advanced features according to project needs.
