Android : java.lang.OutOfMemoryError:

Question

I developed an application that uses lots of images on Android.

There are lots of images present in drawable folder say more then 100, I am developing application for animation of images. I used imageview to show GIF images. I have used the concept of Split gif images into multiple PNG format images and then use it.

Each time the user enters to the app, I can see the memory growing more and more until user gets the java.lang.OutOfMemoryError.

So what is the best/correct way to handle many images?

Below is my code:

dog_animation.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/DogView"
android:orientation="vertical" >

<ImageView
    android:id="@+id/dog_animation"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="0.19" />

dog_animation.xml (Drawable folder)

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

Dog_Animation.java

public class Dog_Animation extends Activity {

Timer timer = new Timer();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    setContentView(R.layout.dog_animation);

    ImageView img = (ImageView) findViewById(R.id.dog_animation);
    img.setBackgroundResource(R.drawable.dog_animation);
    AnimationDrawable frameAnimation = (AnimationDrawable) img
            .getBackground();
    frameAnimation.start();

    timer.schedule(new TimerTask() {
        public void run() {
            Intent intent = new Intent(Dog_Animation.this,
                    Man_Animation.class);
            startActivity(intent);
        }
    }, 10000);
}
}

Now the problem is when i try to move from one activity to another which has same some other image to animate it's giving me error of java.lang.OutOfMemory.

I have tried with so many different solution like

@Override
protected void onDestroy() {
    super.onDestroy();

    unbindDrawables(findViewById(R.id.DogView));
    System.gc();
}

private void unbindDrawables(View view) {
    if (view.getBackground() != null) {
        view.getBackground().setCallback(null);
    }
    if (view instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {
            unbindDrawables(((ViewGroup) view).getChildAt(i));
        }
        ((ViewGroup) view).removeAllViews();
    }
}

and so other also but any solution is not working for me. Please help me to solve this issue. even i have referred http://androidactivity.wordpress.com/2011/09/24/solution-for-outofmemoryerror-bitmap-size-exceeds-vm-budget/ this link but not getting solve the issue.

Answer 1

In your AndroidManifest.xml keep this inside application tag, add largeHeap like this:

<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"/>
