Error "APK specifies a version code that has already been used.." while deploying to Google Play store from Azure DevOps

I'm trying to deploy our Nativescript app to the Google Play Store using a YML pipeline in Azure DevOps. There is a deployment task that automatically increases the versionCode and versionNumber, which always used to work fine.
However now that we upload, I get this error:
##[error]Error: Failed to upload the bundle /Users/runner/work/1/_Android/app-release.aab. Failed with message:
Error: APK specifies a version code that has already been used..
I see that the latest version in Google Play store is 1.0.3601
In the release pipeline I see that the versionCode generated is 1.0.3603 and versionName is 1.0.3604
How can this be solved? What am I doing wrong?

As suggested by User Kingston Fortune - Stack Overflow, make sure to change versionCode and versionName in build.gradle file:
defaultConfig {
applicationId "com.my.packageId"
minSdkVersion 16
targetSdkVersion 27
versionCode 2 <-- increment this by 1
versionName "2.0" <-- this is the version that shows up in playstore,
remember that the versioning scheme goes as follows.
first digit = major breaking changes version
second digit = minor changes version
third digit = minor patches and bug fixes.
e.g versionName "2.0.1"
}
References: Upload failed You need to use a different version code for your APK because you already have one with version code 2 , Problem with build version when publishing APK to Play Store , https://github.com/bitrise-steplib/steps-google-play-deploy/issues/31 and https://developer.android.com/studio/publish/versioning#appversioning

versionName of re-uploading app after previous version was rejected

Our app had been rejected because of All File Access Permission and now we modified app compliant with google policy. We are going to upload updated version. Our app version 5.0.1 was rejected and versionCode was 51. But now I want to keep same version 5.0.1 and increase versionCode by one i.e. 52. Can I still use same versionName and increase versionCode by 1?

Yes. As #DarShan said, versionName in your build.gradle is just a label, you can arbitrarily name it. Such a restriction you mind is for versionCode. The versionCode you must set it larger number than the previous version.
defaultConfig {
minSdk 31
targetSdk 31
versionCode 1 // integer value
versionName 'Version.2021-10-28' // just a String value
}

Error uploading a new update on Google Play

I have tried to rebuild the apk 5 times with diferent number of versionCode and
versionName, like this
versionCode 8
versionName "8.0"

The application I installed on Google Play does not work on android 5 version and android 6 version. What would be the reason?

The application I installed on Google Play does not work on android 5 version and android 6 version. What would be the reason ?"The application is closed." error is displayed on the screen. Application Google Play Store Link : link
Gradle Code:
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.frtparlak.EnglishWordTest"
minSdkVersion 16
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

( A guess since no stacktrace is attached )
While you define 'minSDKVersion 16' you are still allowed to use code in your application incompatible with e.G. sdk 16.
Your compiler warns you but if you ignore these warnings and dont handle them your app will crash on some devices.
To fix it you can use the linter or just review your warnings and or your crash report.

How to make my app work in all devices?

i made android app for minSdkVersion 23 and targetSdkVersion 23.while launching i saw that this can only support 5000 devices in 15000 devices.i want to make this app support for all devices.how can i do?
defaultConfig {
applicationId "com.love.ksr_red_app"
minSdkVersion 23
targetSdkVersion 23
versionCode 2
versionName "2.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

It depends on minSdkVersion and targetSdkVersion.
Try making minSdkVersion to lowest OS version to which you make your app compatible with.
And make targetSdkVersion to the latest OS version available. This will make sure that your application is targeting towards all the devices available in the market and will compatible with them.

i want to make this app support for all devices.how can i do?
Well..., That looks practically impossible. Though you can try below thing... which will make your app support most of the devices that are present in the market
1) Launch android studio and Create new project
2) Name new project
3) select the minimum support version user friendly
Look it will be supporting 96 % of the devices in the market
Things to keep in mind :
Very old devices are no more there in market like android 1.0 to 4.0
By doing this way it ensures you are going to give support to the maximum number of the devices you can
It will make and alter the things necessary for you in the project
Most importantly... you have to manage exceptions and build versions via code..!!
There are some devices like VIVO in india or other countries which takes android and modifies it to FuntouchOS which will not let you start your program ON_BOOT_COMPLETED... Such phones are based on android and not purely android like others.
Thats why it is not practically possible to support all the devices which shows you in Google console in numbers; while uploading an app
Hope it helps you or someone else

Change your buile.gradle with this configration.
**android {
compileSdkVersion 25
defaultConfig {
applicationId "com.websinfotech.apptophonecallexample"
minSdkVersion 15
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}
}**
