Android Studio 第五十五期 - Studio3.0升级到gradle3.0.0后API失效方案

刚刚升级了正式版的Android Studio3.0部分API不能用了，但是官网还是给出了解决方案，不过很模糊，需要自己琢磨，今天带大家一起看看。

首先gradle3.0之前的多版本打版方法：（可以看出挺费劲的~）

apply plugin: 'com.android.application'
apply plugin: 'android-apt'

def demo1 = '0001';//DemoAPK1
def demo2 = '0002';//DemoAPK2

android {

//    signingConfigs {
//        debug {
//            keyAlias '****'
//            keyPassword '****'
//            storeFile file('签名文件.jks路径')
//            storePassword '****'
//        }
//        release {
//            keyAlias '****'
//            keyPassword '****'
//            storeFile file('签名文件.jks路径')
//            storePassword '****'
//        }
//    }

compileSdkVersion 25
buildToolsVersion "25.0.2"
sourceSets {

jniLibs.srcDirs = ['libs']
}
}

packagingOptions {

exclude 'META-INF/LICENSE'
exclude 'META-INF/LICENSE.txt'
exclude 'META-INF/NOTICE.txt'
}

defaultConfig {

}
signingConfig signingConfigs.debug

manifestPlaceholders = [

}

}

def int minSdk = 21;
def int targetSdk = 25;
def String appId = 'com.example.p031_mokuaihua_viewpager_fragment';

def int vCode = 1;
def String vNameCode = vCode + "";
productFlavors {
//demo1 DemoAPK1_T_1_0001 线上
DemoAPK1 {
minSdkVersion minSdk

targetSdkVersion targetSdk
versionCode vCode
versionName "DemoAPK1_" + "T_" + vNameCode + "_" + demo1

ndk {

}
}

// 自定义输出配置
applicationVariants.all { variant ->
variant.outputs.each { output ->
def outputFile = output.outputFile
if (outputFile != null && outputFile.name.endsWith('.apk')) {
//                def fileName = "UerbT_v${variant.versionName}_${releaseTime()}_${variant.flavorName}.apk"
def fileName = "${variant.versionName}.apk"
output.outputFile = new File(outputFile.parent, fileName)
}
}
}

productFlavors.all { flavor ->
def currentMode = flavor.versionName.split("_")[3]
def currentEnvironment = flavor.versionName.split("_")[1]
def stValue = true
// t == currentEnvironment 以前的判断条件
if (currentEnvironment.endsWith("T")) {//判断是否为测试版 是否以T结尾
stValue = false
} else {
stValue = true
}
if (currentMode == demo1) {
flavor.manifestPlaceholders = [DEMO2_CONFIG_VALUE: ".demo2.factorys.Demo2Factory1", STATISTICS_VALUE: stValue]
} else if (currentMode == demo2) {
flavor.manifestPlaceholders = [DEMO2_CONFIG_VALUE: ".demo2.factorys.Demo2Factory2", STATISTICS_VALUE: stValue]
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:recyclerview-v7:25.3.1'
compile 'com.android.support:design:25.3.1'
compile 'com.android.support:cardview-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'

//the third file
compile 'com.jakewharton:butterknife:8.2.1'
apt 'com.jakewharton:butterknife-compiler:8.2.1'
compile 'com.android.support:multidex:1.0.1'

}

这里说一下：gradle3.0后apt就废除了，现在都是这样的方法：

compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

再来看看gradle3.0后是什么样的：

apply plugin: 'com.android.application'

def demo1 = '0001';//DemoAPK1
def demo2 = '0002';//DemoAPK2

android {

//    signingConfigs {
//        debug {
//            keyAlias '****'
//            keyPassword '****'
//            storeFile file('签名文件.jks路径')
//            storePassword '****'
//        }
//        release {
//            keyAlias '****'
//            keyPassword '****'
//            storeFile file('签名文件.jks路径')
//            storePassword '****'
//        }
//    }

是不是简单很多，Google真是越来越叼~
