Answer 1

change in build.gradle "project: layout xml"

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'

       
    }
} allprojects {
    repositories {
        jcenter()

    }
}

Open Android SDK Manager and make sure you have Build Tools 19.1 downloaded. Double-check.

Then find build/app.gradle and change buildToolsVersion number to '19.1':

apply plugin: 'android'

android {
    compileSdkVersion 19
    buildToolsVersion '19.1'
    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 19

    }

I had the same problem. This is what me solved this problem.

Step 1: Go To SDK Manager

Step 2: Upgrade your Android sdk Build-Tool From current to updated version. (In my case am upgrade it to 21.1.2)

Step 3: Rebuild your application.

This Steps Solved My Problem. Hope it solves your problem too.

I found the problem, build.gradle was on the wrong folder

Answer 5

I have just recently updated my android studio to 0.6.0, and it was giving me the same problem. But my build was 19.0.3, instead of 19.1.0. I changed the buildToolsVersion "19.0.3" to --> "19.1.0" which it forced the Gradle to download the updates. I restarted my Android Studio, and the error went away. Not sure exactly how to explain, but I think it forces it to download the patch off the Maven site, and does its justice behind scenes. And just as Gabriel Matusevich said, the build.gradle is located ProjectFolder -> AppFolder -> build.gradle

Exception: I havn't completed tested this out, but I did notice the Gradle was downloaded from the site, I havn't added or deleted code, or ran the application yet. So to be sure, remember the buildToolsVersion number you had before!
