android studio 多渠道打包，調試正式包，build.gradle解析

android studio 多渠道打包，調試正式包，build.gradle解析
1，講解build.gradle檔案。1.1根目錄Android

1.1.1
defaultConfig是Android的根目錄，可以配置包名等資訊，若AndroidMainfest.xml也配置了，以defaultConfig的為準。
1.1.2
signingConfigs是Android的根目錄,可以配置簽名，如：

 

調試時若想直接用正式的簽名包可以在buildType裡配置。

 

buildTypes {    debug {        signingConfig signingConfigs.release    }    release {        minifyEnabled false        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'    }}

 

1.1.3
多渠道打包，修改AndroidMainFest 的meta-data值。
AndroidMainFest 配置如下：

 

${Value} 是動態配置的。

 

 

 

build.gradle配置如下

 

productFlavors {    huawei {        minSdkVersion 14        targetSdkVersion 21        manifestPlaceholders =[Value: huawei]    }    xiaomi {        minSdkVersion 14        targetSdkVersion 21        manifestPlaceholders =[Value: xiaomi]    }}

 

代碼中擷取AndroidMainnifest Value的值

 

//擷取meta欄位public static String getMetaString(Context con,String name){      ApplicationInfo ai = null;        try {            ai = con.getPackageManager().getApplicationInfo(con.getPackageName(), PackageManager.GET_META_DATA);        } catch (PackageManager.NameNotFoundException e) {            e.printStackTrace();        }        Bundle bundle = ai.metaData;        return bundle.getString(name);}

 

打包時直接使用

 

 

最後貼上build.gradle檔案。

 

apply plugin: 'com.android.application'android {    compileSdkVersion 21    buildToolsVersion 21.1.2    defaultConfig {        applicationId caisheng.com.search        minSdkVersion 16        targetSdkVersion 21        versionCode 1        versionName 1.0    }    signingConfigs {        //你自己的keystore資訊        release {            keyAlias 'aolaigo'            keyPassword '123456'            storeFile file('E:/test.jks')            storePassword '123456'        }    }    lintOptions {        checkReleaseBuilds false        // Or, if you prefer, you can continue to check for errors in release builds,        // but continue the build even when errors are found:        abortOnError false    }    buildTypes {        debug {            signingConfig signingConfigs.release        }        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'        }    }    productFlavors {        huawei {            minSdkVersion 14            targetSdkVersion 21            manifestPlaceholders =[Value: huawei]        }        xiaomi {            minSdkVersion 14            targetSdkVersion 21            manifestPlaceholders =[Value: xiaomi]        }    }}dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    // compile (name:'cai',ext:'aar')    // compile project(':cai')  /*  compile 'com.facebook.fresco:fresco:0.6.0'    compile 'com.android.support:appcompat-v7:22.2.0'    compile 'com.github.liuguangqiang.swipeback:library:1.0.2@aar'    compile 'com.sothree.slidinguppanel:library:3.1.1'    compile 'me.dm7.barcodescanner:zbar:1.5'*/}
