Android几种多渠道打包

https://www.cnblogs.com/sunjiachen/p/11457630.html

我这里采用的是android studio的方法

第一，修改app的build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "com.example.james.cookie"
        minSdkVersion 22
        targetSdkVersion 27
        versionCode 3
        versionName "2.1"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
// 1 渠道名称
    productFlavors {
        baidu {}
        xiaomi {}
        qihu360 {}
        huawei {}
    }
// 2 自动替换 AndroidManifest.xml 里面的metadata
    productFlavors.all {
        flavor -> flavor.manifestPlaceholders = [UMENG_CHANNEL: name]
    }
// 3 设置输出APK名称
    applicationVariants.all { variant ->
        variant.outputs.each { output ->
            def outputFile = output.outputFile
            if (outputFile != null && outputFile.name.endsWith('.apk')) {
                def fileName = "driver_${variant.productFlavors[0].name}_v${defaultConfig.versionName}.apk"
                output.outputFile = new File(outputFile.parent, fileName)
            }
        }
    }
}


dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:27.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile'com.mcxiaoke.volley:library:1.0.+'

}

第二，修改app的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="com.example.james.cookie">

    <!-- 允许应用程序联网，以便向我们的服务器端发送数据 -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> 
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <meta-data
            android:name="UMENG_CHANNEL"
            android:value="${UMENG_CHANNEL}" />
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name=".OkActivity">
        </activity>
    </application>

</manifest>

第三，代码中获取meta 数据

private String getChannel() {
    try {
        PackageManager pm = getPackageManager();
        ApplicationInfo appInfo = pm.getApplicationInfo(getPackageName(), PackageManager.GET_META_DATA);
        String channel = appInfo.metaData.getString("UMENG_CHANNEL");  // key为<meta-data>标签中的name
        if (!TextUtils.isEmpty(channel)) {
            return channel;
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return null;
}
