问题
I am working on creating activity that has too many animations, and when starting this activity the logcat shows me this message again and again during the life time of this activity:
I/Choreographer﹕ Skipped 36 frames! The application may be doing too much work on its main thread.
so I did many stuff in another threads, but still there is heavy access on the main UI thread. as well as, the animation is becoming really slow on some high resolution devices
what can be possible solution for handling this problem ?
UPDATED: added code
so here is the code of showing the views(which are 6 imageButtons),
private void setupAnimationForAllViews(ArrayList<View> listOfViews,
int animationId,
final boolean isAppearing) {
int startDelay = mDelay; // milliseconds
int numberOfViews = listOfViews.size();
for (int i = 0; i < numberOfViews; i++) {
final Animation animator = AnimationUtils.loadAnimation(mContext, animationId);
animator.setStartOffset(startDelay);
startDelay += mOffSet; // every view will start after 100 milliseconds from the other
final View currentView = listOfViews.get(i);
final int indexOfCurrentCheckedItem = i;
mMainUIThreadHandler.post(new Runnable() {
@Override
public void run() {
currentView.startAnimation(animator);
}
});
}
}
I trigger it in seperated thread like this:
new Thread(new Runnable() {
@Override
public void run() {
setupAnimationForAllViews(tempListOfViews,
animationId, isAppearing);
}
}).start();
In the same activity i have Ken Burns View, which implement ken burns effect on 2 images, The code of this kenBurnsView is in this link: KenBurnsView
so this is the main activity xml:

This is the main activity java part:

回答1:
I reduced the sizes and a little bit the resolution of images for Kenburns and the buttons backgrounds in order to get it working smoothly. Playing with threads did not solve the issue of lagging for me.
