Gradle - 如何从AndroidManifest获取值？

Question

build.gradle适用于Android项目的内部

task runAndroidApplication(type: Exec, dependsOn: ':installDebug') {
    //TODO update Activity name below or find a way to get it from AndroidManifest.xml
    if (System.properties['os.name'].toLowerCase().contains('windows')) {
        // windows
        commandLine 'cmd', '/c', 'adb', 'shell', 'am', 'start', '-n', "com.example.androidapptorun.MainActivity"      
    } else {
        // linux 
        commandLine 'adb', 'shell', 'am', 'start', '-n', "com.example.androidapptorun.MainActivity"
    }
}

如何从AndroidManifest获取默认Activity的主Activity值？(此外,如果有多个活动,选择一个会使逻辑长,而处理是在Android工具中)

有没有更好的方法从Android插件然后解析AndroidManifest.xml？

更新:https://github.com/novoda/gradle-android-command-plugin可能适合某些需求,但我需要无参数版本才能通过http://marketplace.eclipse.org/content在Eclipse中快速运行/ gradle这个

Answer 1

你可以使用XmlSlurper课程.

例:

AndroidManifest.xml中

<manifest package="com.example.your.app">

并在gradle中检索它

def manifest = new XmlSlurper().parse(file("AndroidManifest.xml"))

// returns "com.exmaple.your.app"
manifest.@package.text()

Answer 2

我刚刚为ADT 20(L),Gradle 1.12和com.android.tools.build:gradle:0.12.2.

它适用于口味,构建类型(不要忘记myBuildType.initWith(existingBuildType)),和applicationIdSuffix.

将以下内容放在android { ... }:

applicationVariants.all { variant ->
    if (variant.install) {
         tasks.create(name: "run${variant.name.capitalize()}", type: Exec, dependsOn: variant.install) {
            description "Installs the APK for ${variant.description}, and then runs the main launcher activity."
            def getMainActivity = { file ->
                new XmlSlurper().parse(file).application.activity.find{ it.'intent-filter'.find{ filter ->
                    return filter.action  .find{it.@name.text() == 'android.intent.action.MAIN'} \
                        && filter.category.find{it.@name.text() == 'android.intent.category.LAUNCHER'}
                }}.@name
            }
            doFirst {
                def activityClass = getMainActivity(variant.processManifest.manifestOutputFile)
                commandLine android.adbExe, 'shell', 'am', 'start', '-n', "${variant.packageName}/${activityClass}"
            }
        }
    }
}

对于库,您需要更改applicationVariants为libraryVariants:请参阅手册.

更新:ADT 20,Gradle 2.1和com.android.tools.build:gradle:0.13.1:

applicationVariants.all { variant ->
    if (variant.install) {
        tasks.create(name: "run${variant.name.capitalize()}", type: Exec, dependsOn: variant.install) {
            description "Installs the APK for ${variant.description}, and then runs the main launcher activity."
            def getMainActivity = { file ->
                new XmlSlurper().parse(file).application.activity.find{ it.'intent-filter'.find{ filter ->
                    return filter.action  .find{it.'@android:name'.text() == 'android.intent.action.MAIN'      } \
                        && filter.category.find{it.'@android:name'.text() == 'android.intent.category.LAUNCHER'}
                }}.'@android:name'
            }
            doFirst {
                def activityClass = getMainActivity(variant.outputs.processManifest.manifestOutputFile)
                commandLine android.adbExe, 'shell', 'am', 'start', '-n', "${variant.applicationId}/${activityClass}"

                // or without the XML hacking: commandLine android.adbExe, 'shell', 'monkey', '-p', variant.applicationId, '1'
            }
        }
    }
}
