Execution failed for task ':app:compileDebugAi

Question

I installed Android Studio on my computer. I created a new project but that got me the error below. What can I do?

Error:Execution failed for task ':app:compileDebugAidl'.
> aidl is missing

My Android Studio version is 1.1.0.

This is my build.gradle file:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
        jcenter()
    }
}

And :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "24.1.2"

    defaultConfig {
        applicationId "com.example.jo.cloning_a_login_screen"
        minSdkVersion 13
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
}

Answer 1

The problem was actually in the version Android Studio 1.3 updated from the canary channel. I updated my studio to 1.3 and got the same error but reverting back to studio 1.2.1 made my project run fine.

Answer 2

I had the same error i fixed it by going to the build.gradle (Module: app) and changed this line from :

 buildToolsVersion "23.0.0 rc1"

to :

buildToolsVersion "22.0.1"

You will need to go the SDK Manager and check if you have the 22.0.1 build tools. If not, you can use the right build tools but avoid the 23.0.0 rc1.

Answer 3

I had a similar error with a fresh install of Android Studio 1.2.1.1 attempting to build a new blank app for API 22: Android 5.1 (Lollipop).

I fixed it by simply changing the Build Tools Version from "23.0.0 rc1" to "22.0.1" and then rebuilding.

On Windows, F4 opens the Project Structure and the Build Tools Version can be set in the Modules > app section:

I think all this does is change the setting in the build.gradle file in the app but I didn't want to change that manually just in case it does something more.

Answer 4

Quick fix that worked for me:

Right click on project->"Open Module Settings"->Build Tools Version change to: 22.0.1

Answer 5

Use your file browser and copy-paste the IInAppBillingService.aidl into /app/src/main/aidl/com/android/vending/billing/

Answer 6

I am working with sdk 23.1.0 and gradle 1.3.1. I created a new project edited nothing and got the aidl error. I went into my project gradle file and changed tool to 22.0.1 instead of 23.1.0 and it worked:

   compileSdkVersion 23
   buildToolsVersion "22.0.1" //"23.1.0"
