Q:

aidl is missing in Android Studio

I am trying to run Sample of Google Cloud Messaging for Android using Android SDK Version 6.0, API 23
Now the sample has used API 22 but I want to run for API 23, so the changes I made in application level built.gradle file are as below.
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 'Google Inc.:Google APIs:23'
    buildToolsVersion '23.0.0'

    defaultConfig {
        applicationId "gcm.play.android.samples.com.gcmquickstart"
        minSdkVersion 9
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'LICENSE.txt'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.google.android.gms:play-services-gcm:7.8.0'
    compile 'com.android.support:appcompat-v7:23.0.0'
    // Testing dependencies
    androidTestCompile 'com.android.support.test.espresso:espresso-core:2.1'
    androidTestCompile 'com.android.support.test:runner:0.2'
    androidTestCompile 'com.android.support:support-annotations:23.0.0'
}

I updated Android Studio to the latest version, but now the following error has occurred.
:app:compileDebugAidl FAILED
Error:Execution failed for task ':app:compileDebugAidl'.
> aidl is missing

For the solution I have tried updating android studio as given in the link.

A:

What I did to get past this issue is to first change the build tools to 23.0.1, like so:
compileSdkVersion 23
buildToolsVersion "23.0.1"

and my targetSdkVersion to 23 as well.
And update these parameters in the top level script:
    classpath 'com.android.tools.build:gradle:1.3.0'
    classpath 'com.google.gms:google-services:1.3.0-beta1'

Hope that helps.
