Android uses Gradle multi-channel packaging

Android Development completed. For an open application, we need to publish to a different application market, at the same time we also need to count the number of users in different markets downloads.

(by starting the app to get different values in different markets apk)

The following is a detailed example to illustrate:
1. Add the Meta-data label to the application in Androidmanifest.xml

<applicationandroid:allowbackup="true"android:icon="@drawable/ Ic_launcher "android:label=" @string/app_name ">                <meta-dataandroid:name= "app_channel"android:value="${app_ Channel_value} " />                    <activityandroid:name=". Mainactivity "android:label=" @string/app_name " >                        <intent-filter>            <action android:name="Android.intent.action.MAIN" />            <category android:name="Android.intent.category.LAUNCHER" />        </intent-filter>    </activity></Application>

2, change the Build.gradle file, add in Android {}

android {    // 打包渠道List    productFlavors {        wandoujia {            "豌豆荚"]        }        cn360 {            "360"]        }        baidu {            "百度"]        }        tencent {            "应用宝"]        }        sougou {            "搜狗市场"]        }    }}

Or use the flavor name as ${app_channel_value} using the following method:

android {    // 打包渠道List    productFlavors {        wandoujia {}        cn360 {}        baidu {}        tencent {}        sougou {}    }    // 批量处理，直接使用flavor的name作为APP_CHANNEL_VALUE的值    productFlavors.all->        flavor.=[APP_CHANNEL_VALUE: name]    }}

That's it. Run Gradle assemblerelease drink tea to sit and wait.
After that, you will be able to see various channel packages in build/outputs/apk.

The commands available for Assemble are also:

gradle assembleDebug    //全部Debug版本号gradle assembleRelease  //全部Release版本号gradle assembleBaidu    //指定渠道的Debug和Release版本号gradle assembleBaiduDebug   //指定渠道的Debug版本号gradle assembleBaiduRelease //指定渠道的Release版本号gradle build    //全部渠道的Debug和Release版本号

Finally, I enclose my mainactivity and build.gradle.

 Packagecom.example.myandroid;Importandroid.app.Activity;ImportAndroid.content.pm.ApplicationInfo;ImportAndroid.content.pm.PackageManager;ImportAndroid.content.pm.PackageManager.NameNotFoundException;ImportAndroid.os.Bundle;ImportAndroid.widget.Toast;/** * Application Portal * * @author shanhy ([email protected]) * @date December 30, 2015 * * Public  class mainactivity extends Activity {    @Override    protected void onCreate(Bundle savedinstancestate) {Super. OnCreate (Savedinstancestate);        Setcontentview (R.layout.activity_main); String channel = Getappmetadata ("App_channel");if(Channel! =NULL) Toast.maketext ( This, channel, Toast.length_short). Show (); }/** * Get application below metadata * * @param name * @return * @author SHA Nhy * @date December 30, 2015 * *     PublicStringGetappmetadata(String meta_name) {Try{ApplicationInfo AppInfo = This. Getpackagemanager (). Getapplicationinfo (Getpackagename (), packagemanager.get_meta_data);returnAppInfo.metaData.getString (Meta_name); }Catch(Namenotfoundexception e)        {E.printstacktrace (); }return NULL; }}
