Question

我是新手。我刚刚在flutter中创建了一个新项目，甚至都没有更改代码。当我运行代码时，出现以下错误。

Launching lib\main.dart on SM A750F in debug mode...
Gradle task assembleDebug failed with exit code -1
Exited (sigterm)

我不知道如何解决这个问题，它搜索了很多方法

当我跑扑医生时，我得到了这个错误，

Android toolchain - develop for Android devices (Android SDK version 29.0.2)
    X Android license status unknown.
      Try re-installing or updating your Android SDK Manager.
      See https://developer.android.com/studio/#downloads or visit https://flutter.dev/setup/#android-setup for detailed instructions.

我不知道这是否与上面的错误有关。

build.gradle（app）

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 GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.dev.teamo"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

预先感谢

Answer 1

我尝试了从 here 创建的这个，因为我无法通过所有方法让它工作：

在root/android/gradle/wrapper/gradle-wrapper.properties集合中
distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip
在root/android/build.gradle中，设置 dependencies { classpath 'com.android.tools.build:gradle:3.3.2' }
检查 root/android/app/build.gradle SDK 版本是否设置为最低 28： compileSdkVersion 28 和 targetSdkVersion 28

这样做后我的项目成功构建

您需要从Android接受licenes才能运行该应用程序：

运行： flutter doctor --android-licenses

并接受终端机上的条款

我没有找到完美的解决方案。我通过重置窗口解决了该问题。现在已接受所有许可证，并且该应用程序可以正常运行。
