There is no targetSdkVersion
of 24, nor is there compileSdkVersion
of 24, at this time. Those will be valid values (presumably) when the next version of Android ships.
For the N Developer Preview, based on my work over here, use:
compileSdkVersion 'android-N'
buildToolsVersion '24.0.0 rc1'
targetSdkVersion 'N'
You also need Gradle 2.10 or higher (see your gradle/wrapper/gradle-wrapper.properties
file or your standalone Gradle installation) and 'com.android.tools.build:gradle:2.1.0-alpha1'
(see the top-level build.gradle
file).
