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>
