This document is for developers that uses Java to make apps for Android. The docs target developers using Android Studio, Eclipse, or IntelliJ.

Releases

Java apps/games use the ouya-sdk.jar library included in the ODK downloadable from the Cortex developer portal.

Xiaomi Libraries

Back to general info

Place the Xiaomi libraries in the following destinations:

assets/MiGameCenterSDKService.apk
libs/SDK_MIBOX_2.0.1.jar

Xiaomi Required Permissions

Back to general info

Xiaomi's SDK requires several additional permissions in AndroidManifest.xml in order to work.

	<uses-permission android:name="com.xiaomi.sdk.permission.PAYMENT"/>
    <uses-permission android:name="android.permission.GET_TASKS"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

Xiaomi Initialization

Back to general info

Using Java, prepare a Bundle with additional key/value pairs which are used to initialize the OuyaFacade.

	// Your developer id can be found in the Developer Portal
	public static final String DEVELOPER_ID = "00000000-0000-0000-0000-000000000000";

	// Both of these values will be emailed to you by the Cortex team after you've been 
	// selected by the Cortex team
	public static final String XIAOMI_APP_ID = "0000000000000";
	public static final String XIAOMI_APP_KEY = "000000000000000000";

	// All product IDs that might be used
	public static final String[] ALL_PRODUCT_IDS = new String[] {
		"long_sword",
		"sharp_axe",
		"100_extra_lives"
	}
	
	// listener for initialization
	private CancelIgnoringOuyaResponseListener<Bundle> mInitCompletedListener = null;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		Bundle developerInfo = new Bundle();

		// "tv.ouya.developer_id"
		developerInfo.putString(OuyaFacade.OUYA_DEVELOPER_ID, DEVELOPER_ID);
		
		developerInfo.putByteArray(OuyaFacade.OUYA_DEVELOPER_PUBLIC_KEY, loadApplicationKey());

		// We must tell the OuyaFacade that we can use the Xiaomi market for purchases.
		
		// "com.xiaomi.app_id"
		developerInfo.putString(OuyaFacade.XIAOMI_APPLICATION_ID, XIAOMI_APP_ID);
		
		// "com.xiaomi.app_key"
		developerInfo.putString(OuyaFacade.XIAOMI_APPLICATION_KEY, XIAOMI_APP_KEY);
		
		// "tv.ouya.product_id_list"
		developerInfo.putStringArray(OuyaFacade.OUYA_PRODUCT_ID_LIST, ALL_PRODUCT_IDS);
		
		// initialization listener callbacks
        mInitCompletedListener = new CancelIgnoringOuyaResponseListener<Bundle>() {
            @Override
            public void onSuccess(Bundle info) {
            	Log.i(TAG, "InitCompletedListener: onSuccess");
            }

            @Override
            public void onFailure(int errorCode, String errorMessage, Bundle optionalData) {
            	Log.i(TAG, "InitCompletedListener: onFailure errorCode="+errorCode+" errorMessage="+errorMessage);
            }
        };
	        
		// Get the OUYA Facade instance
		OuyaFacade ouyaFacade = OuyaFacade.getInstance();
	        
		// Register the init callback
		ouyaFacade.registerInitCompletedListener(mInitCompletedListener);

		// Pass the Activity for the context parameter when initializing the OuyaFacade.
		// Passing the application context for the context paramter will not work on Xiaomi.
		ouyaFacade.init(this, developerInfo);

		super.onCreate(savedInstanceState);
	}

Disable Xiaomi Screensaver

Back to general info

The screensaver should be disabled while your game is running. Invoke View.setKeepScreenOn(true) to disable the screensaver. Here is a common scenario of an activity loading the layout and using the content View to disable the screensaver.

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		View content = (View)findViewById(android.R.id.content);
		if (null != content) {
			// Disable screensaver
			content.setKeepScreenOn(true);
		}
	}

Create a Xiaomi-specific icon

Back to general info

The ouya_xiaomi_icon.png 284x160 icon should be places in res/drawable-xhdpi/ouya_xiaomi_icon.png.

Localization Resources

Back to general info

Java uses standard Android localization for localized string resources.

Strings can be placed in designated folders which are automatically selected using the current language.

res/values/strings.xml (Default)
res/values-de/strings.xml (Dutch)
res/values-en/strings.xml (English)
res/values-es/strings.xml (Spanish)
res/values-fr/strings.xml (French)
res/values-it/strings.xml (Italian)
res/values-zh-rCN/strings.xml (Simplified Chinese)

Localization Example

Java Examples

Virtual Controller Example

The virtual controller example exercises the new OUYA-Everywhere input. The button names and images are now accessible from the API. And the virtual controller buttons highlight with multiple controllers for supported controllers. TextViews display the incoming keycode values and the remapped keycodes after the OuyaInputMapper has remapped the input.

The AndroidVirtualController source code can be found within the ouya-sdk-examples.

The AndroidVirtualController example uses the OuyaController.getButtonData API to display device specific controller images.

Android Virtual Controller Project

The project has a small number of key files that makes the example work.

AndroidManifest.xml

Specifies the target Android API level of 16 and the starting activity.

MainActivity.java

The starting and only activity in the project responsible for the logic to display text, buttons, and toggle image visibility based on input.

DebugInput.java

A debug class for displaying keycode and axis value input in human-readable format in the logcat.

ouya-sdk.jar

The Java library released through the ODK in the developer portal which provides access to the OUYA SDK.

activity_main.xml

The Android layout that specifies the position and content that displays text and images.

drawables

The drawable resources hold the icons and controller images used in the example.

Example Code

MainActivity

The MainActivity extends the OuyaActivity from the ouya-sdk.jar for the easiest way to add OUYA-Everywhere input.

public class MainActivity extends OuyaActivity {

setDrawable

Accepts the ImageView that will display the button image and the keyCode id for the corresponding button image.

	private void setDrawable(ImageView imageView, int keyCode) {
		ButtonData data = OuyaController.getButtonData(keyCode);
		if (null != data) {
			imageView.setImageDrawable(data.buttonDrawable);
		}
	}

bitmap

The ButtonData image can also be converted to a Bitmap which can be used in other cases.

    private Bitmap getButtonDataBitmap(int button) {
    	OuyaController.ButtonData buttonData = OuyaController.getButtonData(button);
        if (null == buttonData)
        {
            return null;
        }
        BitmapDrawable drawable = (BitmapDrawable)buttonData.buttonDrawable;
        if (null == drawable)
        {
            return null;
        }
        Bitmap bitmap = drawable.getBitmap();
        return bitmap;
    }

onCreate

Loads the layout and gets the references to the ImageView controls that will handle toggling button visibility when toggled.

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		
		setContentView(R.layout.activity_main);
		super.onCreate(savedInstanceState);
		
		txtSystem = (TextView)findViewById(R.id.txtSystem);
		txtController = (TextView)findViewById(R.id.txtController);
		imgButtonMenu = (ImageView)findViewById(R.id.imgButtonMenu);
		txtKeyCode = (TextView)findViewById(R.id.txtKeyCode);
		imgControllerO = (ImageView)findViewById(R.id.imgControllerO);
		imgControllerU = (ImageView)findViewById(R.id.imgControllerU);
		imgControllerY = (ImageView)findViewById(R.id.imgControllerY);
		imgControllerA = (ImageView)findViewById(R.id.imgControllerA);
		imgControllerL1 = (ImageView)findViewById(R.id.imgControllerL1);
		imgControllerL2 = (ImageView)findViewById(R.id.imgControllerL2);
		imgControllerL3 = (ImageView)findViewById(R.id.imgControllerl3);
		imgControllerR1 = (ImageView)findViewById(R.id.imgControllerR1);
		imgControllerR2 = (ImageView)findViewById(R.id.imgControllerR2);
		imgControllerR3 = (ImageView)findViewById(R.id.imgControllerR3);
		imgControllerDpadDown = (ImageView)findViewById(R.id.imgControllerDpadDown);
		imgControllerDpadLeft = (ImageView)findViewById(R.id.imgControllerDpadLeft);
		imgControllerDpadRight = (ImageView)findViewById(R.id.imgControllerDpadRight);
		imgControllerDpadUp = (ImageView)findViewById(R.id.imgControllerDpadUp);
		imgControllerMenu = (ImageView)findViewById(R.id.imgControllerMenu);
		imgButtonA = (ImageView)findViewById(R.id.imgButtonA);
		imgDpadDown = (ImageView)findViewById(R.id.imgDpadDown);
		imgDpadLeft = (ImageView)findViewById(R.id.imgDpadLeft);
		imgDpadRight = (ImageView)findViewById(R.id.imgDpadRight);
		imgDpadUp = (ImageView)findViewById(R.id.imgDpadUp);
		imgLeftStick = (ImageView)findViewById(R.id.imgLeftStick);
		imgLeftBumper = (ImageView)findViewById(R.id.imgLeftBumper);
		imgLeftTrigger = (ImageView)findViewById(R.id.imgLeftTrigger);
		imgButtonO = (ImageView)findViewById(R.id.imgButtonO);
		imgRightStick = (ImageView)findViewById(R.id.imgRightStick);
		imgRightBumper = (ImageView)findViewById(R.id.imgRightBumper);
		imgRightTrigger = (ImageView)findViewById(R.id.imgRightTrigger);
		imgLeftThumb = (ImageView)findViewById(R.id.imgLeftThumb);
		imgRightThumb = (ImageView)findViewById(R.id.imgRightThumb);
		imgButtonU = (ImageView)findViewById(R.id.imgButtonU);
		imgButtonY = (ImageView)findViewById(R.id.imgButtonY);

Input can be event based, or spawn a thread to set visibility on an interval. The menu button is pressed and the visibility needs to be cleared after an interval rather than waiting for an event to clear it.

    	// spawn thread to toggle menu button
        Thread timer = new Thread()
        {
	        public void run()
	        {
	        	while (mWaitToExit)
	        	{
	        		if (mMenuDetected != 0 &&
	        			mMenuDetected < System.nanoTime())
	        		{
	        			mMenuDetected = 0;
	        			Runnable runnable = new Runnable()
	        			{
		        			public void run()
		        			{
		        				imgButtonMenu.setVisibility(View.INVISIBLE);
		        			}
	        			};
	        			runOnUiThread(runnable);
	        			
	        		}
	        		try
	        		{
	        			Thread.sleep(50);
	        		}
	        		catch (InterruptedException e)
	        		{
	        		}
		        }
			}
        };
		timer.start();

onStart

Initialization displays build information and sets the drawable button images from the new api.

	@Override
	protected void onStart() {
		super.onStart();
		txtSystem.setText("Brand=" + android.os.Build.BRAND + " Model=" + android.os.Build.MODEL + " Version=" + android.os.Build.VERSION.SDK_INT);
		
		setDrawable(imgControllerO, OuyaController.BUTTON_O);
		setDrawable(imgControllerU, OuyaController.BUTTON_U);
		setDrawable(imgControllerY, OuyaController.BUTTON_Y);
		setDrawable(imgControllerA, OuyaController.BUTTON_A);
		setDrawable(imgControllerL1, OuyaController.BUTTON_L1);
		setDrawable(imgControllerL2, OuyaController.BUTTON_L2);
		setDrawable(imgControllerL3, OuyaController.BUTTON_L3);
		setDrawable(imgControllerR1, OuyaController.BUTTON_R1);
		setDrawable(imgControllerR2, OuyaController.BUTTON_R2);
		setDrawable(imgControllerR3, OuyaController.BUTTON_R3);
		setDrawable(imgControllerDpadDown, OuyaController.BUTTON_DPAD_DOWN);
		setDrawable(imgControllerDpadLeft, OuyaController.BUTTON_DPAD_LEFT);
		setDrawable(imgControllerDpadRight, OuyaController.BUTTON_DPAD_RIGHT);
		setDrawable(imgControllerDpadUp, OuyaController.BUTTON_DPAD_UP);
		setDrawable(imgControllerMenu, OuyaController.BUTTON_MENU);
	}

onGenericMotionEvent

The axis events arrive with onGenericMotionEvent after the OUYA-Everywhere has remapped the input.

	@Override
	public boolean onGenericMotionEvent(MotionEvent motionEvent) {
		float lsX = motionEvent.getAxisValue(OuyaController.AXIS_LS_X);
	    float lsY = motionEvent.getAxisValue(OuyaController.AXIS_LS_Y);
	    float rsX = motionEvent.getAxisValue(OuyaController.AXIS_RS_X);
	    float rsY = motionEvent.getAxisValue(OuyaController.AXIS_RS_Y);
	    float l2 = motionEvent.getAxisValue(OuyaController.AXIS_L2);
	    float r2 = motionEvent.getAxisValue(OuyaController.AXIS_R2);

onKeyDown

When a button is pressed the corresponding image is highlighted. When the system button is detected, the image is highlighted for an interval.

	@Override
	public boolean onKeyDown(int keyCode, KeyEvent keyEvent) {
		switch (keyCode)
		{
		case OuyaController.BUTTON_L1:
			imgLeftBumper.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_L3:
			imgLeftStick.setVisibility(View.INVISIBLE);
			imgLeftThumb.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_R1:
			imgRightBumper.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_R3:
			imgRightStick.setVisibility(View.INVISIBLE);
			imgRightThumb.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_O:
			imgButtonO.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_U:
			imgButtonU.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_Y:
			imgButtonY.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_A:
			imgButtonA.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_DOWN:
			imgDpadDown.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_LEFT:
			imgDpadLeft.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_RIGHT:
			imgDpadRight.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_UP:
			imgDpadUp.setVisibility(View.VISIBLE);
			return true;
		case OuyaController.BUTTON_MENU:
			imgButtonMenu.setVisibility(View.VISIBLE);
			mMenuDetected = System.nanoTime() + 1000000000;
			return true;
		}
		return true;
	}

onKeyUp

When the button is no longer pressed the ImageView for the highlighted button is hidden.

	@Override
	public boolean onKeyUp(int keyCode, KeyEvent keyEvent) {
		switch (keyCode)
		{
		case OuyaController.BUTTON_L1:
			imgLeftBumper.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_L3:
			imgLeftStick.setVisibility(View.VISIBLE);
			imgLeftThumb.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_R1:
			imgRightBumper.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_R3:
			imgRightStick.setVisibility(View.VISIBLE);
			imgRightThumb.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_O:
			imgButtonO.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_U:
			imgButtonU.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_Y:
			imgButtonY.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_A:
			imgButtonA.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_DOWN:
			imgDpadDown.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_LEFT:
			imgDpadLeft.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_RIGHT:
			imgDpadRight.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_DPAD_UP:
			imgDpadUp.setVisibility(View.INVISIBLE);
			return true;
		case OuyaController.BUTTON_MENU:
			//wait 1 second
			return true;
		}
		return true;
	}

Razer Virtual Controller Example

The RazerVirtualController example includes virtual controller images and mappings for the Razer Serval Controller. The RazerVirtualController source code can be found within the ouya-sdk-examples.

In-App-Purchases Example

The ODK download in the developer portal includes an in-app-purchase sample application.

OuyaFacade

The OuyaFacade has several listeners for in-app-purchase callbacks.

public class CustomActivity extends Activity
{
	// The tag for log messages
	private static final String TAG = ActivityCommon.class.getSimpleName(); 

	// Your game talks to the OuyaFacade, which hides all the mechanics of doing an in-app purchase.
	private OuyaFacade mOuyaFacade = null;
	
	// listener for fetching gamer info
	private CancelIgnoringOuyaResponseListener<GamerInfo> mRequestGamerInfoListener = null;

	// listener for getting products
	private CancelIgnoringOuyaResponseListener<List<Product>> mRequestProductsListener = null;
	
	// listener for requesting purchase
	private OuyaResponseListener<PurchaseResult> mRequestPurchaseListener = null;
	
	// listener for getting receipts
	private OuyaResponseListener<Collection<Receipt>> mRequestReceiptsListener = null;
}

Implement the listeners to pass to the OuyaFacade IAP methods.

		mRequestGamerInfoListener = new CancelIgnoringOuyaResponseListener<GamerInfo>() {
            @Override
            public void onSuccess(GamerInfo info) {
            	Log.d(TAG, "RequestGamerInfoListener: onSuccess");
            }

            @Override
            public void onFailure(int errorCode, String errorMessage, Bundle optionalData) {
            	Log.d(TAG, "RequestGamerInfoListener: onFailure errorCode="+errorCode+" errorMessage="+errorMessage);
            }
        };
        
		mRequestProductsListener = new CancelIgnoringOuyaResponseListener<List<Product>>() {
			@Override
			public void onSuccess(final List<Product> products) {
				Log.d(TAG, "RequestProductsListener: onSuccess received "+products.size()+" products");
			}

			@Override
			public void onFailure(int errorCode, String errorMessage, Bundle optionalData) {
				Log.d(TAG, "sRequestProductsListener: onFailure errorCode="+errorCode+" errorMessage="+errorMessage);
			}
		};

		mRequestPurchaseListener = new OuyaResponseListener<PurchaseResult>() {

			@Override
			public void onSuccess(PurchaseResult result) {
				Log.d(TAG, "RequestPurchaseListener: onSuccess");
			}

			@Override
			public void onFailure(int errorCode, String errorMessage, Bundle optionalData) {
				Log.d(TAG, "RequestPurchaseListener: onFailure errorCode="+errorCode+" errorMessage="+errorMessage);
			}

			@Override
			public void onCancel() {
				Log.d(TAG, "RequestPurchaseListener: onCancel");
			}
		};
		
		mRequestReceiptsListener = new OuyaResponseListener<Collection<Receipt>>() {

			@Override
			public void onSuccess(Collection<Receipt> receipts) {
				Log.d(TAG, "RequestReceiptsListener: onSuccess received "+receipts.size() + " receipts");
			}

			@Override
			public void onFailure(int errorCode, String errorMessage, Bundle optionalData) {
				Log.d(TAG, "RequestReceiptsListener: onFailure: errorCode="+errorCode+" errorMessage="+errorMessage);
			}

			@Override
			public void onCancel() {
				Log.d(TAG, "RequestReceiptsListener: onCancel");
			}
		};
