Gradle - How to get values ​​from AndroidManifest?

Question

Inside build.gradle for Android project

 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" } } 

How to get value for AndroidManifest core activity for default activity? (Also, if there are several actions, the choice of logic for the logic will be lengthy, while the processing should be inside the Android tools)

Is there a better way from the Android plugin and then parsing AndroidManifest.xml ?

UPDATE: https://github.com/novoda/gradle-android-command-plugin may satisfy some needs, but I need a version without arguments to quickly launch Eclipse via http://marketplace.eclipse.org/content/gradle

Answer 1

I just wrote this for ADT 20 (L), Gradle 1.12 and com.android.tools.build:gradle:0.12.2 .

It works with aromas, build types (don't forget myBuildType.initWith(existingBuildType) ) and applicationIdSuffix .

At the end of android { ... } put the following:

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

For libraries, you need to change applicationVariants to libraryVariants : see the manual .

Update : ADT 20, Gradle 2.1 and 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' } } } }

You can use the XmlSlurper class.

Example:

AndroidManifest.xml

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

and get it in gradle

 def manifest = new XmlSlurper().parse(file("AndroidManifest.xml")) // returns "com.exmaple.your.app" [e-mail] ()
