I was trying to start a flutter project for an App using bluetooth to communicate. For that, I was using flutter blue.
Unfortunately, when trying to run (on an Android device) the first example I created I was met with the following error:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [:flutter_blue] /home/maldus/Projects/flutter/polmac/build/flutter_blue/intermediates/manifests/full/debug/AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 19,
or use tools:overrideLibrary="com.pauldemarco.flutterblue" to force usage (may lead to runtime failures)
If I were on Android Studio, I'd know how to bump up the Android minSdkVersion, but on a flutter project (using VSCode) I was a little lost.
Is it possible to increase the minSdkVersion with flutter, and how?
It is indeed possible to increase minSdkVersion, but it took me way too much time to find it out because google searches mostly yields as result discussions about the absolute minimum Sdk version flutter should be able to support, not how to increase it in your own project.
Like in an Android Studio project, you have to edit the build.gradle file. In a flutter project, it is found at the path ./android/app/build.gradle.
The parameter that needs to be changed is, of course, minSdkVersion 16, bumping it up to what you need (in this case 19).
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion 19 //*** This is the part that needs to be changed, previously was 16
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
Seems obvious now, but took me long enough to figure it out on my own.
Flutter 2.8 or Later
build.gradle update
Before Updating to Flutter 2.8
android {
compileSdkVersion 30
defaultConfig {
applicationId "com.example.app"
minSdkVersion 21
targetSdkVersion 30
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
}
After updating to Flutter 2.8:
android {
compileSdkVersion flutter.compileSdkVersion
defaultConfig {
applicationId "com.example.app"
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
You should change from local.properties following instruction:
First go to the android->local.properties
And changes from here
Change like this from build.gradle
android {
compileSdkVersion localProperties.getProperty('flutter.compileSdkVersion').toInteger()
defaultConfig {
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
If you didn't know, Google Playstore only allows minSdkVersion to be 20 or above. But flutter has still set default minSdkVersion to 16. Can you see that you'll be always obliged to manually change for each new project?
All your suggestions above are good, but they are not the best, because you will be forced to temper with the build.gradle for each new project you create.
The best way is to modify the value of the global minSdkVersion variable from its source, so all projects, new or old, will adopt it. Remember flutter.minSdkVersion means that the variable is in flutter directory (with the sdk).
The file in question is flutter.gradle.
the address is flutter-directory/packages/flutter_tools/gradle/flutter.gradle
class FlutterExtension {
/** Sets the compileSdkVersion used by default in Flutter app projects. */
static int compileSdkVersion = 31
/** Sets the minSdkVersion used by default in Flutter app projects. */
static int minSdkVersion = 16
/** Sets the targetSdkVersion used by default in Flutter app projects. */
static int targetSdkVersion = 31
change the value of the minSdkVersion from 16 to 20 or above, and do not disturb the code in build.gradle.
If you want, you can watch a video I made on Youtube, explaining it under: flutter configure minSdkVersion from 16 to 20 or above
For flutter v2.8
Inside local.properties add
sdk.dir='<path>'
flutter.sdk='<path>'
flutter.buildMode=debug
flutter.versionName=1.0.0
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=30
flutter.compileSdkVersion=30
app-level build.gradle
defaultConfig {
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Now you can use localProperties.getProperty() to read the value from the properties file.
You can change the minSdkVersion in the file Project_Name/android/app/build.gradle , defaultconfig :
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion 16 // <--- There
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
With the new Flutter projects (2.8.0), with the 'Flutter style', you able to change minimum sdk version in local.properties (instead of editing app/build.gradle file).
# android/local.properties
flutter.minSdkVersion=19
Look in android/app/build.gradle file, you'll see the variable constraint like this:
# android/app/build.gradle
android {
defaultConfig {
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
}
Here the detailed solution for changing MinSdk /Minsdk version error, follow the steps.
Add following lines on android\local.properties
sdk.dir=
flutter.sdk=C:\\flutter
flutter.buildMode=debug
flutter.versionName=1.0.0
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=31
flutter.compileSdkVersion=31
Delete existing lines and paste it on app level build.gradle: android\app\build.gradle
defaultConfig {
applicationId "app-id"
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Add the following lines to android/local.properties file:
flutter.versionCode=1
flutter.versionName=0.0.1
flutter.flutterMinSdkVersion=24
flutter.flutterTargetSdkVersion=31
Add the following lines at the top-level in the file may be after "def versionName =" in the file android/app/build.gradle:
def flutterMinSdkVersion = localProperties.getProperty('flutter.flutterMinSdkVersion')
if (flutterMinSdkVersion == null) {
flutterMinSdkVersion = '16'
}
def flutterTargetSdkVersion = localProperties.getProperty('flutter.flutterTargetSdkVersion')
if (flutterMinSdkVersion == null) {
flutterMinSdkVersion = '31'
}
finally edit the section of the build.gradle that match as follows:
defaultConfig {
applicationId "do.main.subdomain" // Use your App ID
minSdkVersion flutterMinSdkVersion.toInteger()
targetSdkVersion flutterTargetSdkVersion.toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Once all this is done you are good to go. Next time you want to update something you only have to change one file.
All answers are best. But the following way is best in changing SdkVersion after Flutter 2.8 :
Go to your root directory where flutter is installed. It should be like
C:\src\flutter\flutter
Then go to
packages>Flutter tools>gradle>
In Gradle, you will see many files, locate flutter.gradle . Right-click on it and edit it with text editor/notepad.
here you will find all SDK versions. Change them, save, and then you are ready to go
the complete path should be like this: (in my case)
C:\src\flutter\flutter\packages\flutter_tools\gradle
Follow these steps to change the minSdkVersion problem.
First=> YouProject_name/android/app/build.gradle
Second=> defaultconfig { //you can find it inside build.gradle }
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.umair.product_details_using_crud"
minSdkVersion 16 // here you can change minSdkVersison
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
I found the best way to fix this so it performs globally across all of your future apps as well is by changing the setting in the flutter.gradle file located in your default build section. If you're using VSCode
go to this location (or the location you've installed flutter)
C:\src\flutter\packages\flutter_tools\gradle\
drag the flutter.gradle file into VSCode
update the min, compile, and/or target versions
save
This is how I approached when I got this issue recently:
Inside <your-project>/android/app/build.gradle
Find android -> defaultConfig -> minSdkVersion and replace it with
minSdkVersion Math.max(flutter.minSdkVersion, 21)
21 here can be replaced by whatever minimum version you would want.
In case flutter start supporting 23 or some other higher version as the minimum version and you decide to upgrade flutter for your project, it would still work.
**android/local.properties**
flutter.versionCode=1
flutter.minSdkVersion=21
flutter.targetSdkVersion=30
flutter.compileSdkVersion=31
**android/app/build.gradle**
minSdkVersion localProperties.getProperty('flutter.minSdkVersion').toInteger()
targetSdkVersion localProperties.getProperty('flutter.targetSdkVersion').toInteger()
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
I encountered this problem setting up Auth0, flutter_appauth and flutter_secure_storage within my flutter app. After changing the minSdkVersion version, I got this error
C:\Users\myusername\AndroidStudioProjects\wole\android\app\src\debug\AndroidManifest.xml Error:
Attribute data#scheme at AndroidManifest.xml requires a placeholder substitution but no value for <appAuthRedirectScheme> is provided.
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : Attribute data#scheme at AndroidManifest.xml requires a placeholder substitution but no value for is provided.
The solution is adding manifestPlaceholders thus
Setting minSdkVersion, targetSdkVersion, and compileSdkVersion are a little bit different starting from Flutter 2.8. Now the gradle file in your_flutter_app/android/app/build.gradle path looks like this:
Just replace the current values with the version numbers you want, like this:
Now run your flutter project, and that's it.
change local.properties file mentioned below.. because currently playstore update minimum target api version atleast 30
sdk.dir=/Users/sweetnandha/Library/Android/sdk
flutter.sdk=/Users/sweetnandha/FlutterDev/flutter
flutter.buildMode=debug
flutter.versionName=1.0.0
flutter.versionCode=1
flutter.compileSdkVersion=32
flutter.minSdkVersion=21
flutter.targetSdkVersion=32
or
It's found inside the defaultconfig on [project_name]/android/app/build.gradle. defaultconfig
you can find out that folder with which flutter ( on mac or linux ) or in windows you can look here https://stackoverflow.com/a/304447/8122500 .
then you can follow guide from #francis-nduba-numbi .
there is 2 type to change from
from flutter.gradle ( recommendation change here for not spesifc/for future )
or direct from build.gradle ( not recommended )
Try this at android/app/build.gradel minSdkVersion 30 that should fix it but make sure you are at kotlin_version = '1.6.10' with your kotlin version.
app/build.gradle add this version code
In the current version of flutter (2.10.4) you should change it by going into
Flutter sdk folder/packages/open flutter_tools open /gradle then open flutter.gradle and find static int minSdkVersion and change as per requirement
e.g:
C:\Workspace\flutter\packages\flutter_tools\gradle\flutter.gradle
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.map"
minSdkVersion 19
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Upgrade your compiled sdk version to 29 - higher
hope this will help you.
this worked. With the new version, it can now be changed directly from the IDE.

first run
flutter clean
then change the minSdkVersion in the file Project_Name/android/app/build.gradle , defaultconfig :
I have a device with android version 10.
Also, I have an emulator with API 22
this is a part of my build.gradle(:app) file:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
android {
dataBinding {
enabled = true
}
compileSdkVersion 'android-R'
defaultConfig {
applicationId "com.example.android.sOnline"
minSdkVersion 17
targetSdkVersion 'R'
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
// android.defaultConfig.javaCompileOptions.annotationProcessorOptions.includeCompileClasspath = true
}
}
It just not working on 'android-R'
Thank you for helping me :)
targetSdkVersion "R" will restrict your app to only running on Android R, by artificially raising your minSdkVersion to R. This has been the case for the past several years: each developer preview only supports running the app on the developer preview itself, not older devices.
Sometime later this year, we will be able to switch to using targetSdkVersion 30, at which point normal behavior returns with respect to minSdkVersion.
Go to build.gradle file
in defaultConfig: change minSdk to 28 and targetSdk to 30
I use a samsung s9 plus, had the same problem and now it works
defaultConfig {
applicationId "com.example.consigness"
minSdk 28
targetSdk 30
versionCode 1
versionName "1.0"
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
For me it was that the virtual device was corrupted , to fix this follow these steps :
open the AVD manager from the top right corner.
delete the device from the actions menu.
create a new one.
choose the new device and run your application.
For future safety before exiting the android studio make sure to close the emulator first.

I am trying to add another activity to my project but it seems like the options for that are greyed out
Here's what it looks like to me:
You need to change your minimum SDK level. That's why it's greyed out - yours is set to be too low.
In your AndroidManifest.xml, right under <manifest . . . >, add this:
uses-sdk android:minSdkVersion="15" />
You can change the value there to any value...you only really need 8 or higher for most of the activities you are trying to add.
I had the same problem to solve.
Go to Gradle and check the following settings:
defaultConfig {
applicationId "com.hawiLLC.hawiblogapp"
minSdkVersion 21
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
Check on the minimum minSdkVersion.
I had the same problem. In order to change the minumun SDK level in a Android Studio project I had to change it in build.gradleinstead of the AndroidManifest.xml. This is part of the file I modified:
android {
compileSdkVersion 'Google Inc.:Google APIs:23'
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.example.myfirstapp"
minSdkVersion 9
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
I'm very confused with gradle versioning settings. I found some information about this build system, but nowhere was written about versioning details. Can you explain what these options mean?
compileSdkVersion
buildToolsVersion
minSdkVersion
targetSdkVersion
The minSdkVersion is most obvious, because it means the minimal API we want to support, e.g. 14 (Android >= 4.0).
The targetSdkVersion:
This attribute informs the system that you have tested against the target version and the system should not enable any compatibility behaviors to maintain your app's forward-compatibility with the target version.
I don't quite understand that.
My case is to support devices from API 15. What are the proper settings for that?
I read somewhere that target should be the highest as possible, Android Studio tells me that too, but when I set this up and try to run on Nexus 5 I get:
Failure [INSTALL_FAILED_OLDER_SDK]
My build.gradle
android {
compileSdkVersion 'android-L'
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "my.package.name"
minSdkVersion 14
targetSdkVersion 'L'
versionCode 1
versionName "1.0"
}
buildTypes {
release {
runProguard false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
According to official doc:
http://developer.android.com/preview/setup-sdk.html#createProject
if you would like to try out new features you should use these values:
compileSdkVersion is set to 'android-L'
minSdkVersion is set to 'L'
targetSdkVersion is set to 'L'
It is the reason of Failure [INSTALL_FAILED_OLDER_SDK].
If you don't need android-L I suggest using these values:
defaultConfig {
applicationId "my.package.name"
minSdkVersion 14
targetSdkVersion 19
versionCode 1
versionName "1.0"
}
Said that, there is an unofficial workaround described here (in any case I suggest that you don't use it)
