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

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:

android:allowBackup="true"

android:icon="${app_icon}"

android:label="${app_name}"

android:roundIcon="${app_icon}"

android:supportsRtl="true"

android:theme="@style/AppTheme">

android:name="APP_CHANNEL"

android:value="${APP_CHANNEL_VALUE}" />

//省略其它内容

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:

android:allowBackup="true"

android:icon="${app_icon}"

android:label="${app_name}"

android:roundIcon="${app_icon}"

android:supportsRtl="true"

android:theme="@style/AppTheme">

android:name="APP_CHANNEL"

android:value="${APP_CHANNEL_VALUE}" />

//省略其它内容

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

package="com.wangyz.multichannel">

android:allowBackup="true"

android:icon="${app_icon}"

android:label="${app_name}"

android:roundIcon="${app_icon}"

android:supportsRtl="true"

android:theme="@style/AppTheme">

android:name="APP_CHANNEL"

android:value="${APP_CHANNEL_VALUE}" />
