Gradle打包动态修改manifest配置隐藏app启动图标

android {
	......
	productFlavors{
		demo {
       	 	applicationId = "com.example.demo"
    	}
	}
	android.applicationVariants.all { variant ->
    	variant.outputs[0].processManifest.doLast {
        	def nam = variant.productFlavors[0].name
        	def taskname = variant.name
        	println '=====productFlavors====='+nam + ' ,task:'+taskname
        	// "demo"是渠道隐藏启动图标
        	if ("demo".equalsIgnoreCase(nam) && taskname.contains("Release")) {
            	String manifestPath = variant.outputs[0].processResources.manifestFile
				println "=====remove launcher icon=====$manifestPath"
            	def manifestContent = file(manifestPath).getText()
				println '=====read manifest string====='+manifestContent
				//<intent-filter>
            		//<action android:name="android.intent.action.MAIN" />
            		//<category android:name="android.intent.category.LAUNCHER" />
        		//</intent-filter>
				//移除LAUNCHER 标记的activity，则没有启动图标
            	manifestContent = manifestContent.replace('LAUNCHER', 'DEFAULT')
				println '=====write manifest string====='+manifestContent
            	new File(manifestPath).write(manifestContent)
        	}
    	}//doLast
