    task clean(type: Delete) {

    }

Answer 1

Gradle files are wrong.

build.gradle project

 buildscript { repositories { jcenter() } dependencies { classpath 'com.android.tools.build:gradle:2.1.2' } } allprojects { repositories { jcenter() } } task clean(type: Delete) { delete rootProject.buildDir } 

module:app

 apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion "23.0.3" defaultConfig { applicationId "com.example.natalia.ministerioproyecto" minSdkVersion 10 targetSdkVersion 23 versionCode 1 versionName "1.0" } sourceSets { main { res.srcDirs = [ '/src/main/res/layout/Polo azul/Formulario Dinara' ] } } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:23.4.0' classpath 'com.android.support:appcompat-v7:23.4.0' }
