如何在同一套件下的Android Studio中发布两个APK？

Question

I want to create a shopping app, where there exists seller side and customer side. So I need to deploy a individual app for seller and for customers. My question is how can I create those under a single package?

Since because my app needs to communicate to firebase real-time database. Under firebase real-time free plan, only one app allowed for one database, maximum number of database can be created under free plan is 1. It recognizing the app on the basis of the package. That's why I need how to create two apk under one package in android studio. Please help me out.

Currently using Android studio v3.3.

Answer 1

Use sub packages for example

com.my.shop  //the package
com.my.shop.clients  //1st sub-package
com.my.shop.sellers  //2nd sub-package

Then write different screens for the subpackages like the first activity can allow users to choose if they are Client or Seller.

hope it helps

Answer 2

package id (app id) is needs to be unique. you can't publish on google play.

Answer 3

有一个简单的解决方案，使购物应用程序的客户的第一个屏幕带有卖方的隐藏按钮（位于屏幕按钮或类似的按钮），当他们单击时，将其重定向到另一个屏幕以显示“第二个” apk。

Answer 4

Write one app , create two sub-package inside it. For instance:

**com.mybrand** // Main package, general-shared codes and screens. This will be your package name and used by Google Play, Firebase etc.

*com.mybrand.customer* // Customer specific screen and codes

*com.mybrand.seller* // Seller specific screen and codes

In this way, codes and screens will be seperated in the same app. If you will decide seperate them in future, you can easily seperate and publish them without any name or package name confusion.

Answer 5

You can't, package must be unique . You can create packages with flavors in gradle:

android {
...

defaultConfig {
    minSdkVersion 8
    versionCode 10
     ...
}

flavorDimensions "flavor"

productFlavors {
    customer {
        flavorDimension "flavor"
        applicationId "com.example.customer"
    }

    seller {
        flavorDimension "flavor"
        applicationId "com.example.seller"
    }
  }

 ... 
}

or

android {
...

defaultConfig {
    minSdkVersion 8
    versionCode 10
    applicationId "com.example"
}

flavorDimensions "flavor"

productFlavors {
    customer {
        flavorDimension "flavor"
        applicationIdSuffix '.customer'
    }

    seller {
        flavorDimension "flavor"
        applicationIdSuffix '.seller'
    }
  }

 ... 
}
