Make you project API Level newer.
For me,the problem occured when my build.gradle content like this:

compileSdkVersion 16
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.xiaoguang.xx"
    minSdkVersion 16
    targetSdkVersion 16
    versionCode 1
    versionName "1.0"
}

After i download the sdk 19 and change build.gradle, the problem was fixed.

compileSdkVersion 19
buildToolsVersion "19.1.0"

defaultConfig {
    applicationId "com.xiaoguang.xx"
    minSdkVersion 19
    targetSdkVersion 19
    versionCode 1
    versionName "1.0"
}

change preview'api
