It seems you didn't specify difference in the names of a and b packages. Below is my working implementation of flavor feature for API 25 and com.android.tools.build:gradle:2.3.1 in the app level build.gradle of AS 2.3.3:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"

    defaultConfig {
        applicationId "com.example"
        minSdkVersion 14
        targetSdkVersion 25
        versionCode 1
        versionName "1.00"
    }

    signingConfigs {
        config {
            storeFile file(STORE_PATH)
            keyAlias KEY_ALIAS
            keyPassword KEY_PASSWORD
            storePassword KEYSTORE_PASSWORD
        }
    }

    productFlavors {
        nosync {
            applicationIdSuffix ".nosync"
            versionNameSuffix '-nosync'
            signingConfig signingConfigs.config
        }
        sync {
            signingConfig signingConfigs.config
        }
    }

    buildTypes {
        release {
            debuggable false
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.config
        }
        debug {
            debuggable true
            signingConfig signingConfigs.config
        }
    }

dependencies {
    ...
}

Take a look on difference

applicationIdSuffix ".nosync"
versionNameSuffix '-nosync'

between nosync and sync flavors. It will change the package name of nosync apk.
