before this, I had compile the android resource 4.4 on my Mac, and modified some files in OS system, I think it is the reason is that, but I've forget which file, Someone encountered this problem yet

In my case I downloaded version 22 of Android M and Android 5.1.1 using Android Studio 1.2.1.1 but when I try to do a Hello World this same error showed me

So the solution was go to do right click in app like the image below and choose "Open Module Settings".....

then there you have 2 options. I've changed both with the last version I had.

Compile SDK version to API 21 Lollipop

and Build Tools Version to 21.1.2

Finally clean the project and Build

UPDATE Here is my build.gradle to compare with your build.gradle.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion '21.1.2'

    defaultConfig {
        applicationId "com.android.bmi"
        minSdkVersion 15
        targetSdkVersion 22
        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-v7:22.2.0'
}

UPDATED

TO Get Android Studio 1.3 follow this steps

1. Open the Settings window by choosing File > Settings.
2. Choose the Appearance & Behavior > System Settings > Updates panel.
3. On the Updates panel, choose the option Automatically check updates for: Canary Chanel.
4. On the Updates panel, select Check Now to check for the latest canary build. 5. Download and install the build when you are prompted.

Then you'll have something like this to update your Android Studio to 1.3 and with this you can test Android M

I solve my issue, set the build tools version from 21.1.2 to 22.0.1, hope it can help who meet the same.

For those you are still getting the "aidl is missing" error:

To me, setting back the build tools version is not a solution at all.

On your top level build.gradle file, try setting: classpath 'com.android.tools.build:gradle:1.3.0' classpath 'com.google.gms:google-services:1.3.1'

and then use buildToolsVersion '23.0.1'.

It worked perfectly for me. I hope it helps others.

Following the screen shots from Jorge's post all you have to do is make sure you do not select Build Tools Version 23.0.0 rc1. I have not fully investigated that version in the IDE or on Google's bug tracker but all I had to do was pick the previous tool version and it worked just fine after doing a clean build. I tried this out with various SDK min versions.

I am running OSX 10.10.3 with Android Studio 1.2.1.1 running on Oracle JDK 1.8.0_45-b14

UPDATED WITH SOLUTION This issue is identical in nature to Execution failed for task ':app:compileDebugAidl': aidl is missing. Please read my post for the proper solution and references to the genesis of the solution.
