Causing OutOfMemoryError in Frame by Frame Animation in Android

android animation memory-leaks out-of-memory

Solution 1

I assume that your animation frame images are compressed (PNG or JPG). The compressed size is not useful for calculating how much memory is needed to display them. For that, you need to think about the uncompressed size. This will be the number of pixels (320x480) multiplied by the number of bytes per pixel, which is typically 4 (32 bits). For your images, then, each one will be 614,400 bytes. For the 26-frame animation example you provided, that will require a total of 15,974,400 bytes to hold the raw bitmap data for all the frames, not counting the object overhead.

Looking at the source code for AnimationDrawable, it appears to load all of the frames into memory at once, which it would basically have to do for good performance.

Whether you can allocate this much memory or not is very system dependent. I would at least recommend trying this on a real device instead of the emulator. You can also try tweaking the emulator's available RAM size, but this is just guessing.

There are ways to use BitmapFactory.inPreferredConfig to load bitmaps in a more memory-efficient format like RGB 565 (rather than ARGB 8888). This would save some space, but it still might not be enough.

If you can't allocate that much memory at once, you have to consider other options. Most high performance graphics applications (e.g. games) draw their graphics from combinations of smaller graphics (sprites) or 2D or 3D primitives (rectangles, triangles). Drawing a full-screen bitmap for every frame is effectively the same as rendering video; not necessarily the most efficient.

Does the entire content of your animation change with each frame? Another optimization could be to animate only the portion that actually changes, and chop up your bitmaps to account for that.

To summarize, you need to find a way to draw your animation using less memory. There are many options, but it depends a lot on how your animation needs to look.

I had the same problem. Android loads all the drawables at once, so animation with many frames causes this error.

I ended up creating my own simple sequence animation:

public class AnimationsContainer {
    public int FPS = 30;  // animation FPS

    // single instance procedures
    private static AnimationsContainer mInstance;

    private AnimationsContainer() {
    };

    public static AnimationsContainer getInstance() {
        if (mInstance == null)
            mInstance = new AnimationsContainer();
        return mInstance;
    }

    // animation progress dialog frames
    private int[] mProgressAnimFrames = { R.drawable.logo_30001, R.drawable.logo_30002, R.drawable.logo_30003 };

    // animation splash screen frames
    private int[] mSplashAnimFrames = { R.drawable.logo_ding200480001, R.drawable.logo_ding200480002 };


    /**
     * @param imageView 
     * @return progress dialog animation
     */
    public FramesSequenceAnimation createProgressDialogAnim(ImageView imageView) {
        return new FramesSequenceAnimation(imageView, mProgressAnimFrames);
    }

    /**
     * @param imageView
     * @return splash screen animation
     */
    public FramesSequenceAnimation createSplashAnim(ImageView imageView) {
        return new FramesSequenceAnimation(imageView, mSplashAnimFrames);
    }

    /**
     * AnimationPlayer. Plays animation frames sequence in loop
     */
public class FramesSequenceAnimation {
    private int[] mFrames; // animation frames
    private int mIndex; // current frame
    private boolean mShouldRun; // true if the animation should continue running. Used to stop the animation
    private boolean mIsRunning; // true if the animation currently running. prevents starting the animation twice
    private SoftReference<ImageView> mSoftReferenceImageView; // Used to prevent holding ImageView when it should be dead.
    private Handler mHandler;
    private int mDelayMillis;
    private OnAnimationStoppedListener mOnAnimationStoppedListener;

    private Bitmap mBitmap = null;
    private BitmapFactory.Options mBitmapOptions;

    public FramesSequenceAnimation(ImageView imageView, int[] frames, int fps) {
        mHandler = new Handler();
        mFrames = frames;
        mIndex = -1;
        mSoftReferenceImageView = new SoftReference<ImageView>(imageView);
        mShouldRun = false;
        mIsRunning = false;
        mDelayMillis = 1000 / fps;

        imageView.setImageResource(mFrames[0]);

        // use in place bitmap to save GC work (when animation images are the same size & type)
        if (Build.VERSION.SDK_INT >= 11) {
            Bitmap bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
            int width = bmp.getWidth();
            int height = bmp.getHeight();
            Bitmap.Config config = bmp.getConfig();
            mBitmap = Bitmap.createBitmap(width, height, config);
            mBitmapOptions = new BitmapFactory.Options();
            // setup bitmap reuse options. 
            mBitmapOptions.inBitmap = mBitmap;
            mBitmapOptions.inMutable = true;
            mBitmapOptions.inSampleSize = 1;
        }
    }

    private int getNext() {
        mIndex++;
        if (mIndex >= mFrames.length)
            mIndex = 0;
        return mFrames[mIndex];
    }

    /**
     * Starts the animation
     */
    public synchronized void start() {
        mShouldRun = true;
        if (mIsRunning)
            return;

        Runnable runnable = new Runnable() {
            @Override
            public void run() {
                ImageView imageView = mSoftReferenceImageView.get();
                if (!mShouldRun || imageView == null) {
                    mIsRunning = false;
                    if (mOnAnimationStoppedListener != null) {
                        mOnAnimationStoppedListener.AnimationStopped();
                    }
                    return;
                }

                mIsRunning = true;
                mHandler.postDelayed(this, mDelayMillis);

                if (imageView.isShown()) {
                    int imageRes = getNext();
                    if (mBitmap != null) { // so Build.VERSION.SDK_INT >= 11
                        Bitmap bitmap = null;
                        try {
                            bitmap = BitmapFactory.decodeResource(imageView.getResources(), imageRes, mBitmapOptions);
                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                        if (bitmap != null) {
                            imageView.setImageBitmap(bitmap);
                        } else {
                            imageView.setImageResource(imageRes);
                            mBitmap.recycle();
                            mBitmap = null;
                        }
                    } else {
                        imageView.setImageResource(imageRes);
                    }
                }

            }
        };

        mHandler.post(runnable);
    }

        /**
         * Stops the animation
         */
        public synchronized void stop() {
            mShouldRun = false;
        }
    }
}

Usage:

FramesSequenceAnimation anim = AnimationsContainer.getInstance().createSplashAnim(mSplashImageView);
anim.start();

don't forget to stop it...

I spent a lot of time on this and have two different solutions, both good..

First, the problem: 1) Android loads all of the images into RAM, in uncompressed Bitmap format. 2) Android uses resource scaling, so on a phone with an xxxhdpi display (such as LG G3), each frame takes up a TON of space, so you quickly run out of RAM.

Solution #1

1) Bypasses Android's resource scaling. 2) Stores the bytearrays of all files in memory (these are small, especially for JPEGs). 3) Generates Bitmaps frame-by-frame, so it is almost impossible to run out of RAM.

Disadvantages: It spams your logs as Android is allocating memory for new Bitmaps and recycling old ones. It also performs lousy on older devices (Galaxy S1), but performs nicely on current budget phones (read: $10 Alcatel C1 I picked up at BestBuy). Second solution below performs better on older devices, but could still run out of RAM in some circumstances.

** Solution #2 **

It loads the XML resource, parses it and loads the raw resources - thereby bypassing Android's resource scaling (which is responsible for most OutOfMemoryExceptions), and creates an AnimationDrawable.

Advantages: Performs better on older devices (eg. Galaxy S1)

Disadvantages: Can still run out of RAM as it's holding all of the uncompressed Bitmaps in memory (but they are smaller because they are not scaled the way Android normally scales images)

public static void animateManuallyFromRawResource(int animationDrawableResourceId, ImageView imageView, Runnable onStart, Runnable onComplete) {
    AnimationDrawable animationDrawable = new AnimationDrawable();

    XmlResourceParser parser = imageView.getContext().getResources().getXml(animationDrawableResourceId);

    try {
        int eventType = parser.getEventType();
        while (eventType != XmlPullParser.END_DOCUMENT) {
            if (eventType == XmlPullParser.START_DOCUMENT) {

            } else if (eventType == XmlPullParser.START_TAG) {

                        if (parser.getAttributeName(i).equals("drawable")) {
                            int resId = Integer.parseInt(parser.getAttributeValue(i).substring(1));
                            byte[] bytes = IoUtils.readBytes(imageView.getContext().getResources().openRawResource(resId));
                            drawable = new BitmapDrawable(imageView.getContext().getResources(), BitmapFactory.decodeByteArray(bytes, 0, bytes.length));
                        }
                        else if (parser.getAttributeName(i).equals("duration")) {
                            duration = parser.getAttributeIntValue(i, 66);
                        }
                    }

            }
        }
    }, animationDrawable.getDuration(frameNumber));
}

If you are still having memory issues, use smaller images... or store the resource name + duration, and generate the byte-array + Drawable on each frame. That would almost certainly cause too much chopping between frames, but uses almost zero RAM.

Solution 4

I've created an animation class that displays frames based on passed in drawables resources and frames durations.

 protected class SceneAnimation{
    private ImageView mImageView;
    private int[] mFrameRess;
    private int[] mDurations;
    private int mDuration;

    private int mLastFrameNo;
    private long mBreakDelay;

 public SceneAnimation(ImageView pImageView, int[] pFrameRess, int[] pDurations){
        mImageView = pImageView;
        mFrameRess = pFrameRess;
        mDurations = pDurations;
        mLastFrameNo = pFrameRess.length - 1;

        mImageView.setImageResource(mFrameRess[0]);
        play(1);
    }

    public SceneAnimation(ImageView pImageView, int[] pFrameRess, int pDuration){
        mImageView = pImageView;
        mFrameRess = pFrameRess;
        mDuration = pDuration;
        mLastFrameNo = pFrameRess.length - 1;

        mImageView.setImageResource(mFrameRess[0]);
        playConstant(1);
    }

    public SceneAnimation(ImageView pImageView, int[] pFrameRess, int pDuration, long pBreakDelay){            
        mImageView = pImageView;
        mFrameRess = pFrameRess;
        mDuration = pDuration;
        mLastFrameNo = pFrameRess.length - 1;
        mBreakDelay = pBreakDelay;

        mImageView.setImageResource(mFrameRess[0]);
        playConstant(1);
    }


    private void play(final int pFrameNo){
        mImageView.postDelayed(new Runnable(){
            public void run() {
                mImageView.setImageResource(mFrameRess[pFrameNo]);
                if(pFrameNo == mLastFrameNo)
                    play(0);
                else
                    play(pFrameNo + 1);
            }
        }, mDurations[pFrameNo]);
    }


    private void playConstant(final int pFrameNo){
        mImageView.postDelayed(new Runnable(){
            public void run() {                    
                mImageView.setImageResource(mFrameRess[pFrameNo]);

                if(pFrameNo == mLastFrameNo)
                    playConstant(0);
                else
                    playConstant(pFrameNo + 1);
            }
        }, pFrameNo==mLastFrameNo && mBreakDelay>0 ? mBreakDelay : mDuration);
    }        
};

It is used like this:

 private ImageView mTapScreenTextAnimImgView;    
private final int[] mTapScreenTextAnimRes = {R.drawable.tap0001_b, R.drawable.tap0002_b, R.drawable.tap0003_b, 
        R.drawable.tap0004_b, R.drawable.tap0005_b, R.drawable.tap0006_b, R.drawable.tap0005_b, R.drawable.tap0004_b,
        R.drawable.tap0003_b, R.drawable.tap0002_b, R.drawable.tap0001_b};
private final int mTapScreenTextAnimDuration = 100;
private final int mTapScreenTextAnimBreak = 500;

and in onCreate:

 mTapScreenTextAnimImgView = (ImageView) findViewById(R.id.scene1AnimBottom);
    new SceneAnimation(mTapScreenTextAnimImgView, mTapScreenTextAnimRes, mTapScreenTextAnimDuration, mTapScreenTextAnimBreak);

Solution 5

I had this problem and solved it by doing the two following things:

Cut the resolution of the animation images in half...1/4 the size in uncompressed bytes.
Put the images in the drawable-nodpi folder so they don't get scaled up by Android for you.

My animation was still failing to load on some phones after doing step 1. Step 2 got it working on those phones.

Hope this saves somebody else some time.

EDIT: I was still experiencing crashes after going to the Activity that plays the AnimationDrawable but I have it working now. Here are the additional things I did:

Do not use an animation-list in xml. Instead create the AnimationDrawable each time you need to use it. Otherwise, the next time you load the animation drawable from the resource it will still be trying to use the bitmaps you end up recycling.
Recycle the bitmaps in the AnimationDrawable when you are done using it. This is the magic that frees up the memory.
Use the Android Device Monitor to monitor the allocated bytes in your heap.

Here is code I am using for creating the AnimationDrawable:

    protected AnimationDrawable CreateLoadingAnimationDrawable()
    {
        AnimationDrawable animation = new AnimationDrawable ();
        animation.OneShot = false;
        for (int i = 0; i < kNumberOfFrames; ++i) {
            int index = (i * 2) + 1;
            string stringIndex = index.ToString ("00");
            string bitmapStringId = kBaseAnimationName + stringIndex;
            int resID = this.Resources.GetIdentifier (bitmapStringId, "drawable", this.PackageName);
            Bitmap bitmap = BitmapFactory.DecodeResource (this.Resources, resID);
            BitmapDrawable frame = new BitmapDrawable (bitmap);
            //Drawable frame = Resources.GetDrawable (resID);
            animation.AddFrame (frame, 111);
        }
        return animation;
    }

And code for freeing up the bitmaps when you are done using them. You could do this in OnPause or OnDestroy. _loadingAnimation is my AnimationDrawable created above. I would love to know what SetCallback() does for you in this case. I just copied that from somewhere else on SO.

        if (_loadingAnimation != null) {
            _loadingAnimation.Stop ();
            _loadingImageView.SetBackgroundResource (Resource.Drawable.loading_anim_full7001);
            for (int i = 0; i < _loadingAnimation.NumberOfFrames; ++i) {
                BitmapDrawable frame = _loadingAnimation.GetFrame (i) as BitmapDrawable;
                if (frame != null) {
                    Android.Graphics.Bitmap bitmap = frame.Bitmap;
                    bitmap.Recycle ();
                    frame.SetCallback(null);
                }
            }
            _loadingAnimation.SetCallback(null);
            _loadingAnimation = null;
        }

Scorpion about 4 years

I am having lots of images as frames in my resources/drawable folder (let say approx 200). And using this images i want run a animation. The longest animation is of 80Frames. I am successfully able to run the animation on click of the buttons for some, but for some of the animation it is giving me OutOfMemoryError saying that VM can't provide such memory. It is out of VM Budget. I count the size of all of the images its about 10MB. The size of each image is 320x480 in pixels.

I try googling and found that i need to explicitly call the Garbage Collector using System.gc() method. I have done that but still i am getting some time error of memory. Can anyone please kindly help me out in this.

Some Code:-

ImageView img = (ImageView)findViewById(R.id.xxx);
img.setBackgroundResource(R.anim.angry_tail_animation);
AnimationDrawable mailAnimation = (AnimationDrawable) img.getBackground();
MediaPlayer player = MediaPlayer.create(this.getApplicationContext(), R.raw.angry);
    if(mailAnimation.isRunning()) {
    mailAnimation.stop();
    mailAnimation.start();
        if (player.isPlaying()) {
        player.stop();
        player.start();
    }
    else {
        player.start();
    }
}
else {
    mailAnimation.start();
        if (player.isPlaying()) {
        player.stop();
        player.start();
    }
    else {
        player.start();
    }
}

This is the code i have written in on click of a Button.....

Resource file inside res/drawable/anim

<?xml version="1.0" encoding="utf-8"?>

Same way i have different buttons for different animation... Thanks

Scorpion over 12 years

I add the resource file code in the question now. Thanks for your quick reply. Please kindly let me know where i am making mistake.
Scorpion over 12 years

@ LYRICSBOY ,Thanks for your response. You might heard about the Talking Tom Cat game in android and others also. I want exactly the same thing in my app. I am having frames of size 320x480 pixels as i told earlier, so I search about sprites on google and found that sprites are useful for small size images not for large pngs. And for Bitmap Factory i don't know that how i can load all this frames in one Bitmap object or how to run my animation using Bitmap classes instead of AnimationDrawable.
Scorpion over 12 years

@ JAFFER, Thanks for your answer, but using thread how can i load my images? Can you please give me some hint or tip that how should i go ahead. I found in many sites to use Bitmap or BitmapFactory.options but i don't know anything about how to use this classes in my case.
lyricsboy over 12 years

It looks like you can use AnimationDrawable in code (rather than XML) and use addFrame(Drawable, int) to pass your own drawables, also created in code using BitmapDrawable to wrap Bitmaps created using BitmapFactory. Or you could try creating your own subclass of DrawableContainer (the superclass of AnimationDrawable) that is more suited to your needs. OR you could just create a game-style drawing loop that fires as often as possible but no faster than your desired frame rate and loads the bitmaps from the resources in some kind of smart cache.
Scorpion over 12 years

@ LYRICSBOY, Can you please guide me how can I use BitmapFactory , BitmapDrawable & Bitmap for my application as i never used this things before ever. I used addFrame in my code before this AnimationDrawable but in that I am getting the same error. But i have not used thread to run the animation. Does that make any difference?
lyricsboy over 12 years

The code associated with this article has some examples of using BitmapFactory. A quick search should find you several more.

Works really great. For OnAnimationStoppedListener I added an interface with only one method void AnimationStopped(). Also I changed it a little bit so that I can have a oneshot animation.
Horyun Lee almost 10 years

I have improve this class and uploaded to github. Please click here who have a problem with oom with frame animation.
Alon Levanon almost 10 years

For some reason, the animation is not smooth and it is taking more time than it should. My array is building dynamically (on main thread) so I've switched to ArrayList (~200 elements) and my interval is 34ms (30fps). Any suggestions?
Asaf Pinhassi over 9 years

If the animation runs slow, its probably because the frames are loaded on real-time... My suggestion would be to set the images to the same size and type and make sure that "if (Build.VERSION.SDK_INT >= 11) {"... code is running - it should use the same memory allocation for new images and give you better performance
usr30911 over 9 years

@HoryunLee ive downloaded the github code, but the animation keeps on continuing in a loop, stop isnt getting called / or onAnimationEnd listener isnt getting called
Meerschwein Bob almost 9 years

Solution 1 is the Best i found in hours. Just changed: bytes = IoUtils.readBytes(context.getResources().openRawResource(res‌Id)); To: bytes = IOUtils.toByteArray(context.getResources().openRawResource(r‌esId));
Steven L almost 9 years

Thanks for the catch @MeerschweinBob , I had been referencing my own class. I've updated the answer to use the standard IOUtils. I'm glad it (otherwise) helped you.
demo_Ashif over 8 years

@Pinhassi Thnks for your answers . it works perfectly . but I need to stop the animation after running all frames . like I have 81 frames to animate and I want to run this animation for one time not repeatedly . You mentioned about the stop method but when should I call it it .plz give me just a little bit of details for stopping the animation after running all frames . and hey thnks in anvance
Asaf Pinhassi over 8 years

in FramesSequenceAnimation.getNext() you can tell when one loop was finished. just add stop() at that point. (or even better, add "onLoopEnd() call back).

why in the 1st solution you're executing the next frame twice in animateRawManually. once in Handler.postDelayed and once in Thread ?

@Razgriz You just need to call the static methods like ex: loadRaw or animateRawManually
