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
1
2
3
| <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：
1
| 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:
1

| <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:
1

| <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

}

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