基于友盟SDK

1.修改AndroidManifest.xml

<meta-data android:value="${UMENG_CHANNEL_VALUE}" android:name="UMENG_CHANNEL"/>

2.修改module下build.gradle

A.添加打包渠道

android{
  productFlavors {

        xiaomi {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]
        }
        qh360 {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"]
        }

        wandoujia {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "wandoujia"]
        }

        huawei {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "huawei"]
        }
    }
}

B.添加flavorDimensions "versionCode"

defaultConfig {
        applicationId "com.musejianglan.gank"
        minSdkVersion 14
        targetSdkVersion 26
        versionCode 3
        versionName "3.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        flavorDimensions "default"
    }

在defaultConfig中添加flavorDimensions "default"即可，这是是studio3.0引入的新规则

原则上，多渠道基本配置完成。首先builde一下，然后开在AndroidStudio菜单栏点击Build菜单–>Generate signed APK开始打包

如果需要自定义apk的名字

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

            // 自定义输出配置
            applicationVariants.all { variant ->
                variant.outputs.all { output ->
                    outputFileName = "gank_${defaultConfig.versionName}_${variant.productFlavors[0].name}.apk"
                }
            }
        }
    }

注意

如果项目中有多个module进行依赖，保证buildTypes { }子项数量及名称一致
例如

app:

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

            // 自定义输出配置
            applicationVariants.all { variant ->
                variant.outputs.all { output ->
                    def outputFile = output.outputFile
                    if (outputFile != null && outputFile.name.endsWith('.apk')) {
                        outputFileName = "gank_${defaultConfig.versionName}_${variant.productFlavors[0].name}.apk"
//                        output.outputFile = new File(outputFile.parent, outputFileName)
                    }
                }
            }
        }

   }

library:

buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    }

如果app有debug项，子项也要添加同名子项。内容为空即可
