Animation causing out of memory exception

Question

My application provides an outofmemory exception when an animation starts to play. What can I do? The images in animation combined have a size of 512kb, that's 10 images.

My activity class is button_anime .

 public class Button_Anime extends Activity{

private static int SPLASH_TIME_OUT = 500;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash_about);
    ImageView loading =(ImageView) findViewById(R.id.iVArcRail_2);
    loading.setBackgroundResource(R.drawable.about_button_anime);
    AnimationDrawable load =(AnimationDrawable)loading.getBackground();
    load.start();
    new Handler().postDelayed(new Runnable() {
               
        @Override
        public void run() {
               Intent i = new Intent(Button_Anime.this, Home.class); 
            startActivity(i);
            finish();
        }
    }, SPLASH_TIME_OUT);
  }
 }

My activity_splash_about.xml

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/withoutlogo" >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="70dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="10dp"
    android:layout_marginTop="10dp"
    android:background="@drawable/logoline" />

<ImageView
    android:id="@+id/iVArcRail_2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/imageView1"/>
 </RelativeLayout>

This is the animation file. about_button_anime

  <?xml version="1.0" encoding="utf-8"?>
  <animation-list xmlns:android="http://schemas.android.com/apk/res/android" 
  android:oneshot="false" >
  <item
      android:drawable="@drawable/ab1"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab2"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab3"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab4"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab5"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab6"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab7"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab8"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab9"
      android:duration="50"/>
  <item
      android:drawable="@drawable/ab10"
      android:duration="50"/>
  
  </animation-list>

And this is my log cat.

How can I get this animation running?

I have already provided largeHeap="true" .

Answer 1

This will work like charm,

Make sure you put your images in the asset folder.

public class AnimationActivily extends Activity {

private Bitmap log_imgs[];
private Bitmap tempBitmap;
private Handler uiHandler;
private ImageView logo_view;
int img_cnt = 1;
protected int _splashTime = 91;
Thread splashTread;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity_animation_activily);
    logo_view = (ImageView) findViewById(R.id.logo_view);
    log_imgs = new Bitmap[91];
    for (int i = 1; i <= 90; i++) {
        get_Images_Assest(i, "logo_pngs");
    }
    logo_view.setImageBitmap(log_imgs[70]);
    uiHandler = new Handler();
    // thread for displaying the SplashScreen
    splashTread = new Thread() {
        @Override
        public void run() {
            try {
                while (img_cnt < _splashTime) {
                    sleep(30);
                    if (img_cnt <= 90)
                        update_view(img_cnt);
                    img_cnt++;

                }
            } catch (InterruptedException e) {
                // do nothing
            } finally {

                Intent i = new Intent(AnimationActivily.this,
                        MainActivity.class);
                i.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
                startActivity(i);
                AnimationActivily.this.finish();
                // overridePendingTransition(R.anim.slide_in,
                // R.anim.slide_out);
                // *** Put this in another
                // Activity***//overridePendingTransition(R.anim.slide_in,
                // R.anim.slide_out);
            }
        }
    };
    splashTread.start();

}

public Bitmap tempImg;

private void get_Images_Assest(int cnt, String folder_name) {
    try {

        InputStream is = getAssets().open(
                folder_name + "/" + "logo" + cnt + ".png");
        if (tempImg != null) {
            tempImg = null;
        }
        tempImg = BitmapFactory.decodeStream(is);
        // tempBitmap = Bitmap.createScaledBitmap(tempImg,
        // tempImg.getWidth() * 2, tempImg.getHeight() * 2, true);
        log_imgs[cnt] = tempImg;
    } catch (IOException e) {
        e.printStackTrace();
    }
}

public void update_view(final int cnt) {
    uiHandler.post(new Runnable() {
        public void run() {
            try {
                logo_view.setImageBitmap(log_imgs[cnt]);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });

}

public void onBackPressed() {
}

public void onDestroy() {
    super.onDestroy();

    for (int i = 1; i <= 90; i++) {
        log_imgs[i].recycle();
    }
    log_imgs = null;
    splashTread = null;
}
}

Answer 2

I had the same problem, so I created a class to avoid from OutOfMemoryError. Android loads all the drawables at once, so animation with many frames causes this error.

FasterAnimationsContainer

FasterAnimationsContainer will help you to avoid from OutOfMemoryError. This class loads & sets and releases an image on background thread.

here's link

Easy to implement

public class ExampleActivity extends Activity {

FasterAnimationsContainer mFasterAnimationsContainer;
private static final int[] IMAGE_RESOURCES = { R.drawable.anim_1,
        R.drawable.anim_2, R.drawable.anim_3, R.drawable.anim_4,
        R.drawable.anim_5, R.drawable.anim_6, R.drawable.anim_7,
        R.drawable.anim_8 };

private static final int ANIMATION_INTERVAL = 500;// 200ms

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_example);
    ImageView imageView = (ImageView) findViewById(R.id.imageview);
    mFasterAnimationsContainer = FasterAnimationsContainer
            .getInstance(imageView);
    mFasterAnimationsContainer.addAllFrames(IMAGE_RESOURCES,
            ANIMATION_INTERVAL);
    mFasterAnimationsContainer.start();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mFasterAnimationsContainer.stop();
}
}

I had a similar problem with my background animation on devices with low memory. The way I managed to fix it was by instantiating the animation programmatically instead of through the xml animation-list. I no longer run into out of memory issues with this view.

    AnimationDrawable animationDrawable = new AnimationDrawable();
    animationDrawable.setOneShot(false); // True = only once, False = continuous

    int[] resources = {R.drawable.ticket_background_animation_1, R.drawable.ticket_background_animation_2, R.drawable.ticket_background_animation_3};

    int duration = 30;

    for (int resource : resources) {
        animationDrawable.addFrame(ContextCompat.getDrawable(context, resource), duration);
    }

    relativeLayout.setBackground(animationDrawable);
    animationDrawable.start();

It's of course also very important to remember to stop the animation again in onDestroy() !

    ((AnimationDrawable) relativeLayout.getBackground()).stop();
    // Sets background to null to make sure the animation is garbage collected
    relativeLayout.setBackground(null);
