App Setup


For your Android application to be compatible with the Forge TV, it must set the min platform to API 16: Android 4.1 (Jelly Bean) and the target platform to API 21: Android 5.0 (Lollipop).


        android:targetSdkVersion="21" />

Step 1: Add OUYA SDK jar to build path

To access Cortex specific functions, you'll need to download the ODK and add ouya-sdk.jar to the build-path of your app.
This jar can be found in the libs/ folder of the ODK.


If you're using gradle, you can compile against our latest SDK using the following in your build.gradle:

repositories {
    maven {
        url ""
dependencies {
    compile 'ouya:ouya-sdk:+' // You can replace "+" with a specific version number

Step 2: Add intent-filter

For your Cortex app to show up in the PLAY section, it must have an activity that contains a filter for either tv.ouya.intent.category.GAME or tv.ouya.intent.category.APP.


<activity android:name=".GameActivity" android:label="@string/app_name">
    <action android:name="android.intent.action.MAIN"/>
    <category android:name="android.intent.category.LAUNCHER"/>
    <category android:name="tv.ouya.intent.category.GAME"/>

Step 3: Add an icon

All Cortex apps have an icon which is displayed in various places on the system. The icon is expected to be located in res/drawable-xhdpi/ouya_icon.png with the dimensions 732px x 412px

Step 4: Create and secure your keystore

When releasing an APK, it must be signed by a keystore to verify its source. You can create a keystore using built-in wizards in Eclipse and Android Studio/IntelliJ, or via the command line:

keytool -genkey -v -keystore my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000

Additionally, it is CRITICAL that you keep this keystore in a secure place. You will not be able to update your app if you lose your key. Updates must be signed with the exact same key; there is no way to re-create it if lost.
