studio配置參數

1、在項目根目錄下新建一個配置文件，例如：config.gradle【隨便取名】

2、在項目根目錄下的build.gradle文件頭，引用配置文件，例如：apply from: "config.gradle"

3、app或lib目錄下的build.gradle文件裏引用：

    方法一：rootProject.【配置文件標籤】.【子標籤】["【key】"]

    方法二：rootProject.【配置文件標籤】.【子標籤】.【key】

 

例如：

config.gradle 文件：

/**
 * 全局統一配置
 */
ext {
    /**
     * 版本統一管理
     */
    versions = [

            /*
            * 指紋識別
            * */
            fingerprintVersionCode  : 23,
            fingerprintVersionName  : "0.2.3",

            /*
            * 虹軟面部識別
            * */
            arcFaceVersionCode      : 1,
            arcFaceVersionName      : "0.0.1",

            compileSdkVersion       : 29,
            minSdkVersion           : 19,
            targetSdkVersion        : 29,

            androidSupportSdkVersion: "29.0.0",
            appcompatVersion        : "1.0.2",
            constraintlayoutVersion : "1.1.3",
            junitVersion            : "4.12",
            runnerVersion           : "1.2.0",
            espressoVersion         : "3.2.0"

    ]

    dependencies = [
            "appcompat"          : "androidx.appcompat:appcompat:${versions["appcompatVersion"]}",
            "constraintlayout"   : "androidx.constraintlayout:constraintlayout:${versions["constraintlayoutVersion"]}",
            "runner"             : "androidx.test:runner:${versions["runnerVersion"]}",
            "espresso_core"      : "androidx.test.espresso:espresso-core:${versions["espressoVersion"]}",
            "junit"              : "junit:junit:${versions["junitVersion"]}",
            //註釋處理器
            "support_annotations": "com.android.support:support-annotations:${versions["androidSupportSdkVersion"]}"

    ]
}

 

目錄根目錄build.gradle文件：

apply from: "config.gradle"

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url 'https://jitpack.io' }
        
    }
}

 

app或lib目錄下build.gradle文件：

defaultConfig {
    applicationId "com.hailong.biometrics.fingerprint.example"
    minSdkVersion rootProject.ext.versions.minSdkVersion
    targetSdkVersion rootProject.ext.versions.targetSdkVersion
    versionCode rootProject.ext.versions.fingerprintVersionCode
    versionName rootProject.ext.versions.fingerprintVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    vectorDrawables.useSupportLibrary = true
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation rootProject.ext.dependencies["appcompat"]
    implementation rootProject.ext.dependencies["junit"]
    implementation rootProject.ext.dependencies["runner"]
    implementation rootProject.ext.dependencies["espresso_core"]
    implementation rootProject.ext.dependencies["constraintlayout"]

    implementation project(':fingerprint')
//    implementation "com.github.ZuoHailong:BiometricPrompt:0.2.3"
}
