当我试图用任何Android设备运行Flutter项目时，它会显示ProcessException。它可以与IOS模拟器配合使用，但无法在Android设备上运行。

转到安装Flutter SDK的路径我的Flutter SDK路径
即：C:Flutter SDKflutterpackagesflutter_toolsgradle
通过移动编辑flatter.gradle文件
maven {
url 'https://dl.google.com/dl/android/maven2'
}
到jcenter((上方的嵌套存储库标签，如所示
i.e. flutter.gradle file buildscript section will look like this
buildscript {
repositories {
maven {
url 'https://dl.google.com/dl/android/maven2'
}
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
}
或者点击此链接：无法'；t为Flutter项目定位lint-gradle-api-26.1.2.jar
如果不起作用运行以下命令
flutter doctor
然后你可以探究这个问题也尝试更改Android SDK版本**
Gradle尚未在系统上正确安装。
创建一个Android Studio项目(不是Flutter项目(。单击build，它将安装所需的文件。
