java.lang.OutOfMemoryError: bitmap size exceeds VM budget

I am trying to change the layout of my application from portrait to landscape and vice-versa. But if i do it frequently or more than once then at times my application crashes.. Below is the error log. Please suggest what can be done?

Solution 1:

One of the most common errors that I found developing Android Apps is the

java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget

error. I found this error frequently on Activities using lots of bitmaps after changing orientation: the Activity is destroyed, created again and the layouts are “inflated” from the XML consuming the VM memory available for bitmaps.

Bitmaps on the previous Activity layout are not properly deallocated by the garbage collector because they have crossed references to their activity. After many experiments I found a quite good solution for this problem.

First, set the “id” attribute on the parent view of your XML layout:

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/RootView">
        ...

Then, on the onDestroy() method of your Activity, call the unbindDrawables() method passing a reference to the parent View and then do a System.gc().

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

        unbindDrawables(findViewById(R.id.RootView));
        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();
        }
    }

This unbindDrawables() method explores the view tree recursively and:

Removes callbacks on all the background drawables
Removes childs on every viewgroup

Solution 2:

I had got the java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget error at several times

1) When switching from app and back to the app some time later (Press home button and after browsing some url)

2) When login/logout to app frequently (within 10 seconds)

3) When switching the device horizontally/vertically

Finally I solved the error in following way

    public void clearAllResources() {

    // Set related variables null

    System.gc();
    Runtime.getRuntime().gc();
   }

Solution 3:

This is a practical answer, what I tried to avoid this problem at Run-time

Runtime.getRuntime().gc();

Calling Garbage Collector is a good Idea.
