Using animation in android 4.0

I am using this code to animate childViews in a ViewGroup on screen:
zoom_in.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
viewGroup.getChildAt(i).setVisibility(View.VISIBLE);
viewGroup.getChildAt(i).clearAnimation();
if(i<5)
{
i++;
viewGroup.getChildAt(i).startAnimation(animation);
}
else
{
i=0;
}
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
}
});
zoom_out.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
viewGroup.getChildAt(i).setVisibility(View.INVISIBLE);
viewGroup.getChildAt(i).clearAnimation();
if(i<5)
{
i++;
viewGroup.getChildAt(i).startAnimation(animation);
}
else
{
viewGroup.getChildAt(i).startAnimation(zoom_in);
i=0;
}
}
});
The animation zoom_in and zoom_out are simple zoom in and zoom out animations. When I run this code on Android 4.2 or higher it works perfectly. But on lower then it doesnot work similarly. Can anyone explain me or provide any solution for this problem. I want it to work similar on all devices 4.0 and higher.

Android:Rotating LinearLayout leaves a trail

Im rotating a LinearLayout, using an ObjectAnimator. Clicking the button causes the LinearLayout to rotate 360(degrees) with the bottom part as the Pivot.
After the Layout completes the rotation, it leaves back a 'trail'/black mark and the complete view looks odd. How do I avoid this from happening? After the Layout completes the 360 animation, I want the view to look as it did in the beginning (clean basically).
Is there a view.refresh or update command im suppose to call somewhere?
1)How do I have a clean looking view at the end?
2)When the image is is in the intermediatestate, why does the back-part appear black? How do I get that to look while(ie,color of the relative layout)?

Button bt1;
float pivotX=0f;
float pivotY=0f;
int a=0;

#Override

mContainer.setPivotX(pivotX);
mContainer.setPivotY(pivotY);

ObjectAnimator rotate = ObjectAnimator.ofFloat(mContainer, View.ROTATION_X,a);

Edit: Added a thread.
**Edit2:**** Added a handler and commented out the thread

Adding this to the code fixes the view once the animation is competed, but the intermediate stage still looks the same. Will update this once I figure that out.
rotate.addListener(new AnimatorListener()
{
#Override
public void onAnimationStart(Animator animation) {
// TODO Auto-generated method stub
relativeLayout.invalidate();
}
#Override
public void onAnimationRepeat(Animator animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animator animation) {
// TODO Auto-generated method stub
//mContainer.invalidate();
relativeLayout.invalidate();
}
#Override
public void onAnimationCancel(Animator animation) {
// TODO Auto-generated method stub
}
});

Perform action at the end of animation

I've write an Animation for make text of a TextView blink, and i would perform an action after animation ends.
It's possible to intercept end of animation in some way?

AnimationListener listener = new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// Do your stuff
}
};

Reloading Animated sprite while on the game scene Andengine

While on the game play scene, when player fires, the enemy will automatically animate and have to move out from the scene. i tried alot but didn't find the solution.
here is my code.
it = bulletList.iterator();
while (it.hasNext()) {
final Bullet b = (Bullet) it.next();
if (b.sprite.collidesWith(enemy)) {
engine.runOnUpdateThread(new Runnable() {
public void run() {
enemy.animate(new long[]{100,100,100,100,100},10,14,1
, new IAnimationListener() {
#Override
public void onAnimationStarted(AnimatedSprite pAnimatedSprite,int
pInitialLoopCount) {
}
#Override
public void onAnimationLoopFinished(AnimatedSprite pAnimatedSprite,
int pRemainingLoopCount, 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 onAnimationFinished(AnimatedSprite pAnimatedSprite) {
// TODO Auto-generated method stub
detachChild(sprite);
}
});
enemy.setIgnoreUpdate(true);
it.remove();
break;
}
}
}

what is it that's actually happening?
i did not understand...
But i understood your code a bit.And i recommend you to remove the runonupdatethread.
And put your animation code outside the runonupdatetheard and try it.
I animate the sprite directly...
