友盟多渠道打包

友盟多渠道打包，前提需要在友盟里创建应用拿到自己的AppKey

《一》首先在清单文单中添加动态渠道变量

   <!--友盟-->
        <meta-data android:value="5f2bf8c3b4b08b653e91eec0（你自己的APPKey）" android:name="UMENG_APPKEY"/>
        <meta-data android:value="${UMENG_CHANNEL_VALUE}" android:name="UMENG_CHANNEL"/>

可能权限

  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  <uses-permission android:name=" android.permission.ACCESS_NETWORK_STATE" />

<二>在build.gradle设置productFlavors android下添加

 productFlavors {
        kuan {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "kuan"]
        }
        xiaomi {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "xiaomi"]
        }
        qh360 {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "qh360"]
        }
        baidu {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "baidu"]
        }
        wandoujia {
            manifestPlaceholders = [UMENG_CHANNEL_VALUE: "wandoujia"]
        }
    }

或者批量修改

android {  
    productFlavors {
        kuan {}
        xiaomi {}
        qh360 {}
        baidu {}
        wandoujia {}
    }  
 
    productFlavors.all { 
        flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL_VALUE: name] 
    }
}

解决Error:All flavors must now belong to a named flavor dimension. Learn more at https://d.android.com

defaultConfig {
        applicationId "com.example.liangxq.shopping"
        minSdkVersion 24
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        
   flavorDimensions "versionCode"
   }

《三》如果出现Android Generate Signed APK: Errors while building APK. You can find the errors 错误
解决办法 在build.gradle文件添加 想都不要想直接添加

lintOptions { 
checkReleaseBuilds false 
abortOnError false 
} 

不行的话在家这两行

    aaptOptions.cruncherEnabled = false;
    aaptOptions.useNewCruncher = false
   

还是不行的话一起加到android中

配置差不多就完了，接下来就是一顿操作
