This article introduces the relevant knowledge of "how to obtain the current channel when Android multi-channel packaging". In the operation of the actual case, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

First of all, sub-channel packaging is very simple.

Set in the build.gradle of the project

Android {... productFlavors {home_site {dimension "money" manifestPlaceholders = [UMENG_CHANNEL_VALUE: "home_site"]} main_store {dimension "money" manifestPlaceholders = [UMENG_CHANNEL_VALUE: "main_store"]} other_store {dimension "money" manifestPlaceholders = [UMENG_CHANNEL_VALUE: "other_store"]}

Where dimension is a dimension and is set through flavorDimensions.

DefaultConfig {... FlavorDimensions "money"}

The main purpose of setting dimensions is to facilitate management.

There are a total of three channels in this project.

UMENG_CHANNEL_VALUE can be named freely, but the channel name will be used in the statistics of friends in the project, so the naming method of UMENG will be used here.

The next step is to get the current channel name, so that you can set different logic according to different channel packages, such as setting a module to be hidden in versions released on some platforms and displayed on versions of other platforms.

First, you need to define the information variables in the AndroidManifest.xml file.

...

Then you can get it in Application or Activity.

ApplicationInfo applicationInfo = null; try {applicationInfo = getPackageManager (). GetApplicationInfo (getPackageName (), PackageManager.GET_META_DATA); if (applicationInfo = = null) {return;} String value = applicationInfo.metaData.getString ("CHANNEL_NAME"); CommonConfig.CHANNEL_NAME=value; / / set differentiation code System.out.println ("CHANNEL_NAME:" + value) by channel; switch (value) {case "home_site": / / Logic 1 break; case "main_store": / / Logic 2 break Case "other_store": / / logical 3 break;}} catch (PackageManager.NameNotFoundException e) {e.printStackTrace ();}
