来自 Android Studio:
最简单的“运行”是我所追求的。类似于 runShadow 的东西？
生成的代码和构建文件:
thufir@dur:~/AndroidStudioProjects/HelloAndroid$
thufir@dur:~/AndroidStudioProjects/HelloAndroid$ cat build.gradle
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
ext.kotlin_version = '1.1.51'
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir

最佳答案
gradle run 未用于 Android 项目，请尝试使用 assemble[Flavor] 任务之一。要将 apk“安装并运行”到模拟器或 Android 设备中，需要 3 个步骤:
1) 创建 apk。 例如，首先你必须运行:
$ ./gradlew clean assembleDebug
这将生成一个 apk 文件，我假设生成的 apk 名为 app-debug.apk。
2) 在您的设备或模拟器中安装生成的 apk:
$ adb install -r app/build/outputs/apk/debug/app-debug.apk
如果您安装了 adb 并且正在运行模拟器或连接的设备，则输出应该是“成功”。如果您已经安装了相同的 apk，则使用 -r 选项，您可以了解有关其他 adb 安装选项的更多信息。
3) 在您的模拟器或设备中“运行”您的应用:
$ adb shell am start -n "android.kotlin.dur.bounceme.net.helloandroid/android.kotlin.dur.bounceme.net.helloandroid.MainActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
我假设您的 Launcher 是您的 MainActivity，您可以在 AndroidManifest.xml 中更改它，并且您还需要包名称。
