Android Question

Generating unsigned, release apk with Android Studio

I need to generate an unsigned, release APK (where someone else will then sign it and release it to the store- with the someone else handling the keys and everything else). My problem is that Android Studio throws an error whenever I try to build:

app-flavorUnsigned-release-unsigned.apk is not signed. Please configure the signing information for the selected flavor using the Project Structure dialog.

I've tried several, previous methods:

  • Failed at creating an Artifact (can't find any menus with "Artifacts" anywhere, although for editing configurations I found the option to choose a custom Artifact) [Probably best bet]

  • Creating an empty signing config

  • Creating a custom flavor

  • Using the terminal to run
    gradle assemble
    gradle assembleRelease
    (which fail due to one of my important module libraries trying to be built)

Here is my current [app's] build.gradle:

apply plugin: ''

android {
signingConfigs {
unsigned {
storePassword = ""
keyAlias = ""
keyPassword = ""
compileSdkVersion 19
buildToolsVersion "20.0.0"
defaultConfig {
applicationId "hiddenForClientPrivacy"
minSdkVersion 13
targetSdkVersion 20
versionCode 1
versionName "1.0"
signingConfig signingConfigs.unsigned
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), ''
signingConfig signingConfigs.unsigned
unsignedBuild {
debuggable false
versionNameSuffix '-unsigned'
signingConfig signingConfigs.unsigned
debug {

productFlavors {
flavorUnsigned {
versionCode = 1;

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile ''
compile project(':SlidingMenu')
compile ''
compile 'com.github.castorflex.verticalviewpager:library:19.0.1'

Thank you for any and all help.

Post-Help Edit:
As the marked accepted answer shows, I had to clear out the release block. Furthermore, I was clicking on the "Run" button- which should appropriately show an error as I can't run an unsigned release apk on an emulator or device. The accepted answer describes everything.

In the release build type, don't specify a signingConfig at all, and your build won't be signed. Release builds don't pick up the default signing config that debug builds get, so it should work for those.

There's a discussion on the adt-dev mailing list about it.

Bear in mind that to build from Android Studio, you'll need to go to the Gradle tasks window and choose the assembleRelease task; normal builds via "Make Project" don't actually build the final APK.
