Android多渠道打包--Gradle打包

前言

由于App一般都会在多个应用市场上架，为了分析App在每个不同渠道的具体的数据，一般都会对不同渠道打包不同的App。多渠道打包有多种方式，这里只介绍利用Gradle进行多渠道打包。

步骤

1、在AndroidManifest.xml中增加配置

<meta-data            android:name="APP_CHANNEL"            android:value="${APP_CHANNEL_VALUE}" />

其中,APP_CHANNEL为配置的属性名。APP_CHANNEL_VALUE为在build.gradle中配置的变量。

2、在build.gradle中增加productFlavors配置

productFlavors {        baidu {            manifestPlaceholders = [APP_CHANNEL_VALUE: "baidu"]        }        qq {            manifestPlaceholders = [APP_CHANNEL_VALUE: "qq"]        }    }

在这里，增加了两个渠道配置信息：baidu和qq。在manifestPlaceholders的配置中，APP_CHANNEL_VALUE即为在AndroidManifest用到的变量。

注意:Gradle3.0以上版本，需要在defaultConfig节点中增加以下配置：

flavorDimensions "default"

3、渠道名称获取

private String getMetaData(Context context, String key) {        try {            PackageManager packageManager = context.getPackageManager();            ApplicationInfo applicationInfo = packageManager.getApplicationInfo(context                    .getPackageName(), PackageManager.GET_META_DATA);            return applicationInfo.metaData.getString(key);        } catch (Exception e) {            e.printStackTrace();        }        return "";    }

4、修改应用名称

productFlavors {        baidu {            manifestPlaceholders = [app_name: "@string/app_name_baidu", APP_CHANNEL_VALUE: "baidu"]        }        qq {            manifestPlaceholders = [app_name: "@string/app_name_qq",APP_CHANNEL_VALUE: "qq"]        }    }

在manifestPlaceholders中增加app_name的配置，在AndroidManifest.xml中引用:

<application        android:allowBackup="true"        android:icon="${app_icon}"        android:label="${app_name}"        android:roundIcon="${app_icon}"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <meta-data            android:name="APP_CHANNEL"            android:value="${APP_CHANNEL_VALUE}" />        //省略其它内容    </application>

5、修改应用图标

productFlavors {        baidu {            manifestPlaceholders = [app_name: "@string/app_name_baidu",app_icon:"@mipmap/icon_baidu", APP_CHANNEL_VALUE: "baidu"]        }        qq {            manifestPlaceholders = [app_name: "@string/app_name_qq", app_icon:"@mipmap/icon_qq",APP_CHANNEL_VALUE: "qq"]        }    }

在manifestPlaceholders中增加app_icon的配置，在AndroidManifest.xml中引用:

<application        android:allowBackup="true"        android:icon="${app_icon}"        android:label="${app_name}"        android:roundIcon="${app_icon}"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <meta-data            android:name="APP_CHANNEL"            android:value="${APP_CHANNEL_VALUE}" />        //省略其它内容    </application>

6、修改应用包名

productFlavors {        baidu {            applicationIdSuffix ".baidu"            manifestPlaceholders = [app_name: "@string/app_name_baidu",app_icon:"@mipmap/icon_baidu", APP_CHANNEL_VALUE: "baidu"]        }        qq {            applicationIdSuffix ".qq"            manifestPlaceholders = [app_name: "@string/app_name_qq", app_icon:"@mipmap/icon_qq",APP_CHANNEL_VALUE: "qq"]        }    }

增加applicationIdSuffix属性。

7、Java中调用gradle中的变量

buildTypes {        debug {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            buildConfigField "String","FIELD_TEST","\"FIELD_TEST\""        }        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            buildConfigField "String","FIELD_TEST","\"FIELD_TEST\""        }    }

增加buildConfigField。同步后，通过BuildConfig.FIELD_TEST能获取到新增的变量值。

8、完整的gradle

apply plugin: 'com.android.application'android {    compileSdkVersion 28    defaultConfig {        applicationId "com.wangyz.multichannel"        minSdkVersion 21        targetSdkVersion 28        versionCode 1        versionName "1.0"        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"        flavorDimensions "default"    }    buildTypes {        debug {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            buildConfigField "String","FIELD_TEST","\"FIELD_TEST\""        }        release {            minifyEnabled false            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'            buildConfigField "String","FIELD_TEST","\"FIELD_TEST\""        }    }    productFlavors {        baidu {            applicationIdSuffix ".baidu"            manifestPlaceholders = [app_name: "@string/app_name_baidu",app_icon:"@mipmap/icon_baidu", APP_CHANNEL_VALUE: "baidu"]        }        qq {            applicationIdSuffix ".qq"            manifestPlaceholders = [app_name: "@string/app_name_qq", app_icon:"@mipmap/icon_qq",APP_CHANNEL_VALUE: "qq"]        }    }}dependencies {    implementation fileTree(dir: 'libs', include: ['*.jar'])    implementation 'com.android.support:appcompat-v7:28.+'    implementation 'com.android.support.constraint:constraint-layout:1.0.2'    testImplementation 'junit:junit:4.12'    androidTestImplementation 'com.android.support.test:runner:1.0.1'    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'}

9、完整的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.wangyz.multichannel">    <application        android:allowBackup="true"        android:icon="${app_icon}"        android:label="${app_name}"        android:roundIcon="${app_icon}"        android:supportsRtl="true"        android:theme="@style/AppTheme">        <meta-data            android:name="APP_CHANNEL"            android:value="${APP_CHANNEL_VALUE}" />        <activity android:name=".MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN" />                <category android:name="android.intent.category.LAUNCHER" />            </intent-filter>        </activity>    </application></manifest>
