uses-sdk:minSdkVersion 16不能小于声明的版本19[Flutter v 2 . 8 . 1]

Question

我正在尝试将火基添加到我的颤振项目中。我收到此错误：

uses-sdk:minSdkVersion 16 cannot be smaller than version 19 declared in library [com.google.firebase:firebase-analytics-ktx:20.0.1] /home/sonu/.gradle/caches/transforms-2/files-2.1/798243125f1f7594aa48e9bc333d339c/jetified-firebase-analytics-ktx-20.0.1/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.google.firebase.analytics.ktx" to force usage (may lead to runtime failures)

我最近将我的flutter更新到verison 2.8.1，我试图更改我的minSdk，但没有成功。

这是完整的日志：

请有人帮我解决这个问题。

Answer 1

您需要在./android/app/build中更新您的最低SDK。梯度示例：

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"
}

Answer 2

机器人-

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutter_calismalari"
        minSdkVersion 21
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }

将minSdkVersion从16设置为21
