I have created a new Flutter project, and this is how the minSdkVersion looks like in the app/build.gradle
file:
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Where is the value of flutter.minSdkVersion
set?
Note that previously, that config value looked like the following:
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"
}
Also, this is the content of the android/local.properties
file:
sdk.dir=/Users/usernaem/Library/Android/sdk
flutter.sdk=/Users/username/flutter
flutter.buildMode=release
flutter.versionName=1.0.0
flutter.versionCode=1
As you can see, the value of flutter.minSdkVersion
is not set there, but the project can be compiled and built successfully.
Where are the flutter.minSdkVersion
and flutter.targetSdkVersion
variables initialized?
PS related issue: https://github.com/flutter/flutter/issues/95533
Go to this file in your flutter extracted folder:
flutter/packages/flutter_tools/gradle/flutter.gradle
There you can find all static variables.
You should change from local.properties following instruction:
First go to the android-> local.properties
And changes from here local.properties
add this line
flutter.minSdkVersion=19
flutter.targetSdkVersion=28
flutter.compileSdkVersion=28
NB: you don't find the local.properties
you create yourself
Put in your android/local.propertie
file the variable:
Example:
flutter.minSdkVersion=21
And change in android/app/build.gradle
localProperties.getProperties('flutter.minSdkVersion') // flutter.minSdkVersion
Just replace flutter.minSdkVersion
with your required value such as 19
like old style
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.projectname"
minSdkVersion 19
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
Follow the path /android/app/build.gradle
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.sample.com"
// You can update the following values to match your application needs.
// For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-build-configuration.
minSdkVersion 23
targetSdkVersion 33
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
}`
