Flutter Application publish Version code 1 has already been used. Try another version code

I wont to upload my update number 12 code version to correct some bugs and I test many Solutions but always When I upload my appbundels Google play console return this messages "Version code 1 has already been used. Try another version code."
Last App bundle uploaded
11 (1.0.0)
pubspec.yaml
version: 1.0.2+2
android/app/build.gradle
`def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '2'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0.2'
}`
android/local.proprieety
flutter.versionCode=2
flutter.versionName=1.0.2
I change many time my version code to 1.0.0+13
I run pub get
I restar my computer and my IDE
I run App before build bundels

Update version:1.0.2+3 in pubspec.yaml.
and save it
and run these commands :
flutter clean
flutter pub get
flutter build appbundle

Version code 1 has already been used. Try another version code

I am uploading new app bundle to play console and it is saying after uploading Version code 1 has already been used. Try another version code.
I have changed version number in pubspec.yaml from version number: 1.0.0+1 to 2.0.0+1 even though it is saying the same error

You have two ways to solve this, if you released your bundle already, then you have to update your version code like in Len_X's answer,
If you're still developing and pushed app bundle for say, testing, and then you delete it, this bundle is saved as a draft with that version code. Therefore, it says that you can't use the same version because it already sees another one with the same version name.
Here's how you fix it:
Go to the release section
go to app bundle explorer, in the top right you should see a dropdown button for you app version, click on it.
A bottomsheet will show containing all the previous app bundles you uploaded it. Delete the one with clashing bundle version and you're good to go.
Hope that solves your problem.

You can do it manually by going to "app_name/android/app/build.gradle" file. In defaultConfig section change version code to a higher number
defaultConfig {
applicationId "com.my.app"
minSdkVersion 23
targetSdkVersion 30
versionCode 1 // Change to a higher number
versionName "1.0.1" // Change to a higher number
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
javaCompileOptions {
annotationProcessorOptions {
arguments = ["room.schemaLocation": "$projectDir/schemas".toString()]
}
}
}

First go to the app/build.gradle
change versionCode and versionName like this (+1)
I think this will be helpful for someone ✌😊

For Flutter only:
Goto Pubspec.yaml file and find version key and Change the value after the + sign.
For Example:
In your pubspec.yaml file, if your version is like this version: 1.0.0+1 then change it to version: 1.0.0+2

You have to increment the +1, it should be +2 to indicate build number

if you remove apk then upload same version apk so you get Error Version code 1 has already been used. Try another version code in this situation you should remove version from App bundle explorer then upload same version apk.

If you're running into app bundle approval issues inside of the Google Play store with an Expo/React Native project, here are some tips:
Google Play versioning is actually checking your AndroidManifest.xml file for versioning (/android/app/src/). This should get updated from Expo's app.json file (/app.json) during build, per their instructions.
app.json example section, where I've bumped my app up to a v2.0 - note the versionCode inside of the Android settings object AND the version at the settings object root both need to be adjusted:
{
"name": "app-name",
"displayName": "App Name",
"expo": {
"android": {
"package": "app.here",
"permissions": [],
"versionCode": 2
}
},
"version": "2.0.0"
}
If your Android version isn't updating (possibly if you have a detached Expo app), you have to go directly into the AndroidManifest.xml file and make the modification there (/android/app/src/):
Example of AndroidManifest.xml (note your modifications happen on the <manifest> tag, using the android:versionCode and android:versionName:
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.aganashapp"
android:versionCode="2"
android:versionName="2.0"
>
<uses-permission android:name="android.permission.INTERNET"/>
<application
android:name=".MainApplication"
android:label="#string/app_name"
android:icon="#mipmap/ic_launcher"
android:allowBackup="false"
android:theme="#style/AppTheme"
>
<meta-data android:name="expo.modules.updates.EXPO_UPDATE_URL" android:value="https://exp.host/#username/app-name" />
<meta-data android:name="expo.modules.updates.EXPO_SDK_VERSION" android:value="42.0.0" />
<meta-data android:name="expo.modules.updates.EXPO_RELEASE_CHANNEL" android:value="default" />
<activity
android:name=".MainActivity"
android:label="#string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize|uiMode"
android:launchMode="singleTask"
android:windowSoftInputMode="adjustResize"
android:theme="#style/Theme.App.SplashScreen"
>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity"/>
</application>
</manifest>
If you're still having issues, remember that Android versionCode and versionName are two different things. Android does not seem to recognize semver standards. versionCode increments as whole numbers (ie, if you went from semver v1.0.0 to v1.1.0 that is versionCode 1 to 2.

with my flutter project building a release for android i faced the same issue. all was doing is change version code in Pubspec.yaml but did not seem to change my android version...
so i went to Android folder and added version code manually in local.properties file :
/project/android/local.properties
flutter.versionName=1.1.0
flutter.versionCode= from 1 to 4

I always used to increment version code in my android/app/build.gradle file, and it always used to work. Then, after a recent update in Android Studio, it suddenly didn't anymore, and I got this error!
I never cared to dig into the build.gradle code, but now, I did. Here, at the "TODO", is where I used to change the version code number:
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new FileNotFoundException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '19' // TODO: ---Count up with each release
}
But that only works if the version code from the local.properties file comes back as "null"!... I just realized. So probably, all this time, my compiler never managed to get values from local properties, but now all of a sudden, it does!
So I found the android/local.properties file and tried changing the version code there:
sdk.dir=C:\\Users\\karol\\AppData\\Local\\Android\\sdk
flutter.sdk=C:\\src\\flutter
flutter.buildMode=release
flutter.versionName=1.0.0
flutter.versionCode=1 //Change this to 19 (my current version code number)
But that didn't work, because the moment I ran flutter build appbundle, this file changed itself back to the original values...
I then tried adding version code values to my AndroidManifest.xml file, according to serraosays' answer, but that didn't help me either.
Functioning work-around
In the end, I did this in the android/app/build.gradle file:
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
//if (flutterVersionCode == null) {
flutterVersionCode = '19' // TODO: ---Count up with each release
//}
That is, I commented out the condition. Now, my setting would over-write any value retrieved from the local.properties file.
If anyone can tell me the proper way to increment the version code number, I'm all ears! 🙂 But in the meantime, this worked for me, and hopefully for someone else as well.

If you get the above error in the google play console, please change the version: in pubspec.yaml.
Reference. How to set build and version number of Flutter app
and me works

The first step change the version code
The second step go to the other settings and change the bundle version code as well

There are two reasons for this error:
First, is common given in other answers: you must increase the version number to send an update to Play Console. Eg. previous app version: 1.0.5+5 and next update must contain 1.1.2+6. The +6 must be next to the previous update present on your play console.
Second reason for this error is you have skipped some numbers in between. Eg. Previous released version: 1.0.5+5 but the new version you are trying to release is 1.0.6+8. The +8 is not allowed directly, you must put +6 then +7 and then next numbers.

In unreal engine you can change this in project settings. Steps are as follows.
(Me I'm using UE4.27.2)
Step 1:
Open Project Settings
Step 2: Click all settings and in the top search bar type in "version" Without Quotes.
Step 3:
Scroll down to >Platforms>Android>apk packaging
Step 4:
Change the store Version for each +1 what you already have
APK PAckaging
(You do not need to change version display name but you can if you want to this can be edited later on in google console)

change version code here please check the imageenter image description here

Versioning works the other way around. Do not update the pubspec.yaml manually.
See the default comment in the pubspec.yaml:
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
So you should run
flutter build appbundle --build-name 2.0.0 --build-number 2
This updates the pubspec.yaml for you.

For hybrid apps/JavaScript based frameworks like Ionic or Flutter updating package.json is not enough you sometimes, can directly edit build.gradle file in the build folder.
versionCode 2
versionName "2.0"
This is not a good practice

Change versionCode of an App created in a gradle script

in an Android app I did not develop, but I have to edit, I found this gradle script:
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.ajoberstar:grgit:1.5.0'
}
}
import org.ajoberstar.grgit.Grgit
ext {
git = Grgit.open(currentDir: projectDir)
gitVersionName = git.describe()
gitVersionCode = git.tag.list().size()
gitVersionCodeTime = git.head().time
}
task printVersion() {
println("Version Name: $gitVersionName")
println("Version Code: $gitVersionCode")
println("Version Code Time: $gitVersionCodeTime")
}
The "gitVersionCode" variable is used as "versionCode" of the app in the build.gradle file.
This is the build.gradle file:
// gradle script
apply from: "$project.rootDir/tools/script-git-version.gradle"
//...
defaultConfig {
applicationId "..."
minSdkVersion 17
targetSdkVersion 25
versionCode gitVersionCode
versionName gitVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
When I generate signed APK and try to add to beta version, I get the google error that "Version code already exists", but I do not know how to edit the version code of the app.
My questions are:
what this code actually does?
how to edit the version code of the app?

Git is a version control system. Your project appears to be stored in a Git repository.
Grgit is a Groovy library that works with Git. Your Gradle script is loading this library.
git is an instance of Grgit. git.tag.list() returns a list of the Git tags used in this repository. git.tag.list().size() returns the number of tags in that list.
So, this Gradle script is setting the versionCode to be the number of Git tags used in the project's Git repository.
how to edit the version code of the app?
Either:
Create another Git tag, such as by tagging the version that you are trying to release, or
Change versionCode gitVersionCode to stop using gitVersionCode and use some other numbering system

It appears to be using this library to query git, in order to generate the version name and version code. In terms of the version code, it looks like it's setting it depending on the number of git tags it finds. So, to bump the version code, do a git tag on your release commit.
If that doesn't suit, you could just do it manually and replace
versionCode gitVersionCode
with
versionCode 99
replacing "99" with whatever your version code should be.

Android Gradle 'versionCode' not read from environment variable

I have an Android that I deploy to a Google Play alpha track trough a CI server. For the Android versionCode I make use of the CI build number that I inject into the Gradle script through an environment variable.
This used to work fine; but currently Google Play is not accepting any builds. When I manually trigger a alpha upload build (using the gradle-play-publisher plugin) for Gradle I eventually end up with the following error:
APK has an invalid version code.
So when looking (using aapt dump badging apk-path) at the generated APK I see an empty value for the version code (versionCode='').
The relevant code from the build script:
def appVersionCode = System.getenv("BUILD_NUMBER") as Integer ?: 0
defaultConfig {
...
versionCode appVersionCode
...
}
It seems the variable is not read correctly; however it reads System.getenv("KEY_PASS") correctly to use for signing.
The variable is also set:
❯ echo $BUILD_NUMBER
1234
Does anyone have an idea why this specific variable doesn't seem to be read (anymore)?
Gradle version: 3.5 with Android Gradle plugin 2.3.1.

Try to change your code to this:
def appVersionCode = Integer.valueOf(System.env.BUILD_NUMBER ?: 0)
defaultConfig {
...
versionCode appVersionCode
...
}

In Flutter pubspec.yaml file updated the version to 1.1.0+3 but on uploading to playConsole, still error version code 1

I've tried to upload an updated aab to the playConsole for my application but have got the following error:
Upload failed You need to use a different version code for your APK or
Android App Bundle because you already have one with version code 1.
I've tried to update the version code to 3 in the pubspec.yaml but I'm still getting the same version after uploading the latest generated aab/apk.

Did you try to do a flutter clean before building the second time? The previous build might have been cached.
Other then that, check your android/app/build.gradle file there should be something like this there that sets the version:
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}

Finally resolved it!
The issue was with the android/local.properties file which was not getting updated. I manually updated the version code here and got around the problem.
