How to install two Android application with same package name

Question

I have created an application just like Careem or Uber. I have very little knowledge of Android development at the start of building this app. I created only one application but later I know that I have to develop two separate application. Then I copy one application as original and developed two applications separately.

These two applications working perfectly on multiple devices according to requirement but the issue is that I am not able to install both application simultaneously on the device. What is the solution for this problem?

You can't. Each app must have it's own unique package. If you want to install both apps in one device then change package name of one of the app — m3g4tr0n, Mar 19 '20 at 11:10
Yes, Use this guide to change package name https://stackoverflow.com/questions/16804093/rename-package-in-android-studio — m3g4tr0n, Mar 19 '20 at 11:21
If you are using services like `Firebase` you will have change library specific files too ex `Google-service.json` in case of `Firebase` — m3g4tr0n, Mar 19 '20 at 11:22
That is the problem I am getting now. Because I want to add both these application to firebase for push notification. Both these application have same package. Now kindly guide me what can I do — Waqas Ahmed, Mar 19 '20 at 11:27
Open Firebase Console -> Project Settings -> General -> Your Apps -> Add your other app here and update new `google-services.json` in your android project — m3g4tr0n, Mar 19 '20 at 11:30

You could have done it with something called flavours of android https://developer.android.com/studio/build/build-variants — quealegriamasalegre, Mar 22 '20 at 03:18

In your build.gradle you can set your applicationId. Choose a different applicationId for each app and you can install both on the same phone.

android {
    defaultConfig {
        applicationId "com.example.myapp"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
    }
    ...
}

see https://developer.android.com/studio/build/application-id

I am trying to add these application in Firebase Console, as these application have same package name. What can I do now? – Waqas Ahmed Mar 19 '20 at 11:28
you can't do any thing firebase not allowed to those app who have same package name your to change the package name for other – Amit pandey Mar 19 '20 at 11:37
Change you applicationId in your build.gradle file. then go to your firebase console (https://console.firebase.google.com) then go to your existing project. And create a new app by clicking "+ Add app" fill in you new packagename (applicationId) -> download google-services.json and add this to your android project with the updated packageName (applicationId). That should be it. – HarmenH Mar 19 '20 at 11:41
You do not need to change your projects package structure. – HarmenH Mar 19 '20 at 11:42
