If you get the above error message while working with Android Studio, make sure that you have downloaded the M Preview (23) from SDK Manager under Tools (Preview Channel).

If you have downloaded/updated to 23.0.0 rc1 or higher and you are still facing this issue then you must make sure following changes in your build.gradle (Module:app) file has the compileSdkVersion and buildToolsVersion as in the below example.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 'android-MNC'
    buildToolsVersion "23.0.0 rc1"

    defaultConfig {
        applicationId "org.code2care.app"
        minSdkVersion 'MNC'
        targetSdkVersion 'MNC'
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}
