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

Issue running more than one NativeScript application on the same android device with tns run

NativeScript 2.0.0, Windows 10
When trying to run more than one NativeScript application on the same android device the tns run android command stops with message:
Successfully deployed on device with identifier '192.168.99.100:5555'.
The application is not installed.
After some investigation, I tried to install the app on the android device using adb directly:
adb "-s" "192.168.99.100:5555" "install" "-r" "<path to apk>.apk"
The command responds with the following:
961 KB/s (15394490 bytes in 15.642s)
WARNING: linker: /system/lib/libhoudini.so has text relocations. This is wasting memory and prevents security hardening. Please fix.
pkg: /data/local/tmp/<app name>-debug.apk
Failure [INSTALL_FAILED_CONFLICTING_PROVIDER]
After some investigation on INSTALL_FAILED_CONFLICTING_PROVIDER and found the following links:
https://issues.apache.org/jira/browse/CB-10014
https://code.google.com/p/analytics-issues/issues/detail?id=784
Install shows error in console: INSTALL FAILED CONFLICTING PROVIDER
I can say it's an ugly problem.
Researching some more, in the NativeScript project, in the directory \platforms\android\build\intermediates\exploded-aar\com.google.android.gms\play-services-measurement\8.4.0 directory there is a manifest template that contains:
<provider
android:authorities="${applicationId}.google_measurement_service"
android:name="com.google.android.gms.measurement.AppMeasurementContentProvider"
android:exported="false"/>
But applicationId is never defined, so when more than one app with this provider is added, the second one fails to install.

I have multiple NS apps installed on my phone and emulators; however when you create a new app; check to see if somehow you have ended up with the same internal name. (This can easily happen if you duplicate your prior project)
Open up your main/primary package.json file that resides in the outermost root of your project folder.
Inside this package.json file you should have a key:
"nativescript": {
"id": "org.nativescript.test3",
"tns-android": {
"version": "2.0.0"
}
},
The "id" is the underlying name of the app that will be installed on the phone. In this case; this is the awesome "org.nativescript.test3" project.
If you get duplicate id's then the the app will overwrite the each other when deployed.
There is a second reason this can happen, and the actual cause of this issue was figured out by the author of the question also. But I will stick here for any future people who might run into this so that we have a valid answer.
The author was using Google Play Services plugin, it has a AppMeasurementContentProvider that if you don't have a applicationId set in your configuration it will default to a blank id; which then means it will conflict with any other app that is using GPS that also doesn't have a applicationId set.
The real nastyness of this bug is that it will conflict with ANY app from ANY other developer who also left their applicationId blank. And so then only ONE of the apps would be installable; any other app that has a blank applicationId would not be installable on that device.
The solution is to open up your /app/App_Resources/Android/app.gradle file and we will add a new value to it.
The current version as of NativeScript v2.00 looks something like this:
android {
defaultConfig {
generatedDensities = []
}
aaptOptions {
additionalParameters "--no-version-vectors"
}
}
If you recall the first part of this answer and about duplicate ids; the package.json we referenced gives you the name you want to use. So in my case I would add to the
defaultConfig {
applicationId = "org.nativescript.test3"
}
So the final file should look something like this:
android {
defaultConfig {
generatedDensities = []
applicationId = "org.nativescript.test3"
}
aaptOptions {
additionalParameters "--no-version-vectors"
}
}
This is related to:
Install shows error in console: INSTALL FAILED CONFLICTING PROVIDER
https://code.google.com/p/analytics-issues/issues/detail?id=784

This workaround worked for me:
in the app/App_Resources/Android/AndroidManifest.xml file add:
<provider
tools:replace="android:authorities"
android:name="com.google.android.gms.measurement.AppMeasurementContentProvider"
android:authorities="MY_APPLICATION_ID.gms.measurement.google_measurement_service"
android:exported="false" />
Where MY_APPLICATION_ID is the application's package (put it manually because __PACKAGE__ didn't work)
Don't forget to declare de tools namespace:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="__PACKAGE__" ...>

Changes Needed after changing package structure of android project?

I am doing one android project in android studio,previously it was working totally fine in Genymotion as well as in actual Mobile phone.
But later when it was needed , I changed my package structure,I made related changes in AndroidManifest.xml and build.gradle.Still after that,it was running perfectly on Genymotion but when I tried running it on mobile phone,it is showing error
Waiting for device.
Target device: samsung-gt_b5330-4d000ef10dee7f00
Uploading file
local path: F:\AppName\app\build\outputs\apk\app-debug.apk
remote path: /data/local/tmp/com.aaa
Installing com.aaa
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/com.aaa"
pkg: /data/local/tmp/com.aaa
Failure [INSTALL_FAILED_OLDER_SDK]
for example let me tell you how old package was for some classes
com.aaa.bbb.ccc.ddd
so my common package for all activity was
com.aaa.bbb
mean all other packages was under this package
so my R package was com.aaa.bbb.R
but then added some data under com.aaa package
so my new common package became com.aaa
because of that new R position became com.aaa.R
because of that I changed
import com.aaa.R
in all classes
also i changed in AndroidManifest.xml to
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.aaa" >
(previously it was package="com.aaa.bbb")
also changed in build.gradle to
defaultConfig {
applicationId "com.aaa" //previously it was applicationId "com.aaa.bbb"
minSdkVersion 16
targetSdkVersion 21
versionCode 1
versionName "1.0"
}
so where else I should make changes ?

The package name on the device must be unique, and there is a conflict when you try to install OVER the existing APK (that is what this means: "Failure [INSTALL_FAILED_OLDER_SDK]")
You should completely delete the old APK from your device, and you will be able to install the new version.

Platform MNC is a preview and requires application manifest to set minSdkVersion to 'MNC'

I have this error in my console.
[2015-06-03 15:29:11 - MainActivity] Platform MNC is a preview and requires application manifest to set minSdkVersion to 'MNC'
[2015-06-03 15:29:12 - debug] Platform MNC is a preview and requires application manifest to set minSdkVersion to 'MNC'
and the manifest is like
<uses-sdk
android:minSdkVersion="10"
android:targetSdkVersion="22" />
how can i resolve this error?

IF you are trying to implement any project for Android M developer preview, You need to set minSDKVERSION ="MNC".

If you want to test the new api in Android M(preview), you have to do that.
But if you don't need, change your build target to other version.
In Eclipse, Properties -> Android, select target other than Android M (Preview)

Platform MNC is a preview and requires application manifest to set minSdkVersion to 'MNC'so you should try SDK INT OF MNC
<uses-sdk android:minSdkVersion="22" android:targetSdkVersion="22" />
In projects Properties -> Android You have to choose other than Android-M, In above example Android 5.1.1, because they have the same API number - API-22
refer this:
Platform L is a preview and requires application manifest to set minSdkVersion to 'L'

I'm not sure if you already resolved this issue or not, but all you need to do is this:
<uses-sdk
android:minSdkVersion="MNC"
android:targetSdkVersion="MNC" />

Error with updating new APK on the developer's console

I have been trying to update my app with the new version and I run into this problem on the developers console. I have such error:
I checked with the version of my previous version to see if I was doing something wrong, but it was the same.
Here is my updated xml file
<application
android:allowBackup="true"
android:id="#+id/title"
android:icon="#mipmap/iron"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:versionCode="100"
android:versionName="2.0"
>

Looks like you already have version 1. in the play store. To be able to update it, you need to change the version number in the build.gradle file in your android project.
Sync your project, then generate the new APK.
I doubt if just updating the manifest will work.

In order to define your app version dynamically, specify a custom method with def and call it, as such in your .gradle:
def computeVersionName() {
return "2.0"
}
android {
compileSdkVersion 19
buildToolsVersion "19.0.0"
defaultConfig {
versionCode 12
versionName computeVersionName()
minSdkVersion 16
targetSdkVersion 16
}
}
