White patches while GameCircle Integration in Cocos2d Android

I am integrating Game Circle SDK & Whisper Sync in my game. I have implemented the code, but it has caused an issue. When I load the game and get the game state from the WhisperSync and set my local variables, white patches are observed in some places randomly instead of the proper image. When I turn of GameCircle & Whisper Sync it runs fine.
My game is developed using Cocos2d Android.
Does any one encountered such issue?
I have attached the image for reference.
Some Code:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
CCGLSurfaceView _glSurfaceView = new CCGLSurfaceView(this);
setContentView(_glSurfaceView);
CCDirector.sharedDirector().attachInView(_glSurfaceView);
CCDirector.sharedDirector().setDisplayFPS(false);
CCDirector.sharedDirector().setAnimationInterval(1.0f / 60.0f);
CCScene scene = IntroLayer.scene();
CCDirector.sharedDirector().runWithScene(scene);
}
#Override
public void onResume() {
super.onResume();
if (IS_AMAZON) {
AmazonGamesClient.initialize(this, callback, myGameFeatures);
AmazonGamesClient.getWhispersyncClient()
.setWhispersyncEventListener(
new WhispersyncEventListener() {
#Override
public void onAlreadySynchronized() {
// TODO Auto-generated method stub
super.onAlreadySynchronized();
System.out
.println("FA here onAlreadySynchronized");
loadGameScene();
}
#Override
public void onDataUploadedToCloud() {
// TODO Auto-generated method stub
super.onDataUploadedToCloud();
System.out
.println("FA here onDataUploadedToCloud");
}
#Override
public void onDiskWriteComplete() {
// TODO Auto-generated method stub
super.onDiskWriteComplete();
System.out
.println("FA here onDiskWriteComplete");
}
#Override
public void onFirstSynchronize() {
// TODO Auto-generated method stub
super.onFirstSynchronize();
System.out
.println("FA here onFirstSynchronize");
loadGameScene();
}
#Override
public void onNewCloudData() {
// TODO Auto-generated method stub
super.onNewCloudData();
System.out
.println("FA here onNewCloudData");
}
#Override
public void onSyncFailed(FailReason reason) {
// TODO Auto-generated method stub
super.onSyncFailed(reason);
System.out
.println("FA here onSyncFailed reason: "
+ reason.name());
}
#Override
public void onThrottled() {
// TODO Auto-generated method stub
super.onThrottled();
System.out.println("FA here onThrottled");
}
});
Log.i(TAG, "onResume: call initiateGetUserIdRequest");
PurchasingManager.initiateGetUserIdRequest();
Log.i(TAG, "onResume: call initiateItemDataRequest for skus: "
+ LAppInfo.getInstance().getList());
Set<String> skus = new HashSet<String>(LAppInfo.getInstance()
.getList());
PurchasingManager.initiateItemDataRequest(skus);
}
CCDirector.sharedDirector().resume();
}
private AmazonGamesCallback callback = new AmazonGamesCallback() {
#Override
public void onServiceNotReady(AmazonGamesStatus status) {
// unable to use service
System.out.println("FA here callback onServiceNotReady: "
+ status.name());
}
#Override
public void onServiceReady(AmazonGamesClient amazonGamesClient) {
System.out.println("FA here callback onServiceReady: ");
agsClient = amazonGamesClient;
}
};
private void loadGameScene() {
LoadData();
CCScene mainMenu = LevelMenuScene.scene();
CCDirector.sharedDirector().replaceScene(
CCFadeTransition.transition(0.5f, mainMenu));
}

Solved it by a work around by having a boolean variable and set it to true after the data is loaded in firstsync/alreadysync method. and loading the scene in the main thread instead of the callback of whispersync. Will be glad to know if some one find a proper solution.

In my view something unwanted shows up

I am building a snake game app.
So fur it works, except for the what it shows.
For some reason it shows two snakes: the original snake that moves and can be controlled, and another begginging of a snake that doesn't do anything.
Before that I drew at every cycle in the loop a background color, so it would cover the last canvas, and there was no problem.
Then I decided to divide the snake from the background, so I have made the snake canvas's background transparent and that it would clear the canvas each time it wants to draw a new canvas (each loop-to move the snake).
Here is the code:
The run of the thread:
public void run() {
long stepPerSecond=1000/FPS;
long startTime;
long sleepTime;
while(isRunning){
Canvas c=null;
startTime=System.currentTimeMillis();
try{
c=this.getHolder().lockCanvas();
synchronized (this.getHolder()) {
this.onDraw(c);
}
}
catch(Exception e){
}
finally{
if(c!=null){
this.getHolder().unlockCanvasAndPost(c);
}
}
sleepTime= stepPerSecond-(System.currentTimeMillis()-startTime);
if(sleepTime>0)
try {
Thread.sleep(sleepTime);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
The snake's ondraw (it uses the snake's class on draw):
public void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
canvas.drawColor(color.transparent, Mode.CLEAR);
snake.onDraw(canvas);
}
The snake's class onDraw:
public void onDraw(Canvas canvas){
switch(dirTransfare(dir)){
case 1://RIGHT
xLoc=xLoc+PART_SIZE;
break;
case 2://UP
yLoc=yLoc-PART_SIZE;
break;
case -1://LEFT
xLoc=xLoc-PART_SIZE;
break;
case -2://DOWN
yLoc=yLoc+PART_SIZE;
break;
}//swich
int x=xLoc;
int y=yLoc;
for(Brick bp:SnakeBody){
bp.setR(0+x, 0+y, PART_SIZE+x, PART_SIZE+y);
canvas.drawRect(bp.getR(),bp.getP());
int xtemp=bp.getX();
int ytemp=bp.getY();
bp.setX(x);
bp.setY(y);
x=xtemp;
y=ytemp;
}//for each
}//onDraw
Here is the mainActivity, which summons the snakeVew and the backgorundView (snake is the game view and the background is the arena)
public class MainActivity extends Activity {
GameView gv;
ImageView left;
ImageView right;
ImageView up;
ImageView down;
Arena a;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*requestWindowFeature(Window.FEATURE_NO_TITLE);
v= new GameView1(this);
setContentView(v);
*/
gv= new GameView(this);
a=new Arena(this);
setContentView(R.layout.game_view);
LinearLayout surface = new LinearLayout(this);
LinearLayout backGround = new LinearLayout(this);
surface = (LinearLayout)findViewById(R.id.surface);
backGround = (LinearLayout)findViewById(R.id.background);
surface.addView(gv);
backGround.addView(a);
left=(ImageView) findViewById(R.id.left);
right=(ImageView) findViewById(R.id.right);
up=(ImageView) findViewById(R.id.up);
down=(ImageView) findViewById(R.id.down);
left.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(gv.snake.getDir()!="LEFT"&&gv.snake.getDir()!="RIGHT"){
gv.snake.Left();
}
}
});
right.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(gv.snake.getDir()!="RIGHT"&&gv.snake.getDir()!="LEFT"){
gv.snake.Right();
}
}
});
up.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(gv.snake.getDir()!="UP"&&gv.snake.getDir()!="DOWN"){
gv.snake.Up();
}
}
});
down.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(gv.snake.getDir()!="DOWN"&&gv.snake.getDir()!="UP"){
gv.snake.Down();
}
}
});
}
The problem is not in the background (the arena class); I have alredy took it down and confirmed that (it worked the same away, with the bug, even without using the arena class).
Here is how it looks with the bug:
http://i.tinyuploads.com/q7oztz.jpg
(you can see two snakes - the long one is the real one)
The blue background is from class arena.
Any ideas? Tnx for help :D

Animated sprite one time and disapear

this.MyAnimatedSprite.animate(50, 0);
this.MyAnimatedSprite.setVisibility(false);
I am new to AndEngine and I want to animate whole AnimatedSprite once and let it disappear. In my code it only animates and stops but does not disappear, if I do setVisible(false).
It does not show animation even once.

You can do this by turning the visibility false after the animation is done.
this.MyAnimatedSprite.animate(50, 0, new IAnimationListener () {
#Override
public void onAnimationFinished(AnimatedSprite pAnimatedSprite) {
this.MyAnimatedSprite.setVisibile(false);
}
#Override
public void onAnimationStarted(AnimatedSprite pAnimatedSprite,
int pInitialLoopCount) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationFrameChanged(AnimatedSprite pAnimatedSprite,
int pOldFrameIndex, int pNewFrameIndex) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationLoopFinished(AnimatedSprite pAnimatedSprite,
int pRemainingLoopCount, int pInitialLoopCount) {
// TODO Auto-generated method stub
}});

How to keep playing YouTubePlayer in Android

Now I'm creating an Android application witch use YouTube api to play Video.
But the player stop when I change Activity.
I want to keep Playing like a Music Player even when Activity will change.
I try to solve that by adding Static on YouTubePlayer.(But cannot solve.)
I mean I want to Keep it's playing when the Activity or the Application itself move to Background.
So if you have any ideas, please share with me :)
-----------------Code-----------------
public class PlayActivity extends YouTubeBaseActivity implements YouTubePlayer.OnInitializedListener,YouTubePlayer.PlayerStateChangeListener{
public static final String DEVELOPER_KEY = "My_Dev_Key";
private LinearLayout yPos;
private static YouTubePlayer yt;
private YouTubePlayerView ytp;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.play);
yPos = (LinearLayout)findViewById(R.id.youtube_pos);
try{
ytp = new YouTubePlayerView(this);
ytp.initialize(DEVELOPER_KEY, this);
}catch(Exception e){
finish();
}
yPos.addView(ytp);

LibGdx - need help on Screen class

I've been using libgdx for the past 3 weeks..
I created two screens referencing to a game:
public class Game extends Game {
TitleScreen titleScreen;
SplashScreen splashScreen;
#Override
public void create() {
// TODO Auto-generated method stub
titleScreen = new TitleScreen(this);
splashScreen = new SplashScreen(this);
setScreen(splashScreen);
}
}
and
public class SplashScreen implements Screen {
Game game;
public SplashScreen(Game game) {
// TODO Auto-generated constructor stub
this.game = game;
}
#Override
public void show() {
// TODO Auto-generated method stub
}
#Override
public void hide() {
// TODO Auto-generated method stub
}
#Override
public void render(float delta) {
// TODO Auto-generated method stub
Gdx.gl.glClearColor(0.5f, 1f, 1f, 1);
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
if(Gdx.input.justTouched()){
game.splashScreen.dispose();
game.setScreen(game.titlescreen);
}
}
#Override
public void resize(int width, int height) {
// TODO Auto-generated method stub
}
#Override
public void pause() {
// TODO Auto-generated method stub
}
#Override
public void resume() {
// TODO Auto-generated method stub
}
#Override
public void dispose() {
// TODO Auto-generated method stub
}
How do I dispose the splashscreen entirely? When I called the game.setscreen(game.splashscreen) in titlescreen class, it resume the splashscreen;. I'm expecting to set a new splashscreen..

Create a new splash screen every time you want to show a splash from the beginning:
game.setScreen(new SplashScreen(game));
