Android custom gradle property detailed explanation and example code

Android custom gradle property

When running a project on Android studio, gradle configuration is essential, but as the project grows gradually, what comes to mind is the addition of various dependency packages, countless signatures, channel packages, etc. The entire gradle becomes very messy. In fact, we can separate part of the content of gradle and put it in another custom gradle. For example, the Plugin we add at this time just assign values ​​to it.

1. step:
2. Create a file in the root directory of the total project (the name can be customized)
3. The custom content created in the root directory is as follows:

It should be noted that when adding additional property to Project in the file, we cannot directly define it, but should define it through ext.

Generally, the code we use closures is as follows:

ext {

//Add supportLibraryVersion property
supportLibraryVersion = '23.1.1'

//Add dependenciesretrofitVersion property
dependenciesretrofitVersion = '2.0.0-beta2'  

//Add dependencies array
dependencies = [

  retrofit       : ":retrofit:$retrofitVersion",

  retrofitConverterGson: ":converter-gson:$retrofitVersion",

  retrofitAdapterRxJava: ":adapter-rxjava:$retrofitVersion",

  ]

}

You can also not use closures

//Add supportLibraryVersion property
 = '23.1.1'

//Add dependenciesretrofitVersion property
 = '2.0.0-beta2'  

Of course, gradle actually provides many custom properties, some commonly used ones include:

project: Project itself

name: Project name

Description: Project description

version: Project version number

path: The absolute path to Project

buildDir: Project build result storage directory

Add under the root directory

apply from: ''

Then add the dependencies under the app project as follows:

dependencies {

  //Get custom array
  Map<String, String> dependencies = 

  compile 

  compile 

  compile 

}

Of course, other configurations can also be configured, such as defaultConfig

defaultConfig under the current app, refer to the configuration parameters

defaultConfig {
  minSdkVersion 
  targetSdkVersion 
}
