java.lang.OutOfMemoryError: bitmap size exceeds VM budget [duplicate]

This question already has answers here: java.lang.OutOfMemoryError: bitmap size exceeds VM budget - Android (13 answers) Closed 5 months ago.

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?

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();
   }


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.


Add this line of code to Android Manifest File inside "application" tag: - android:largeHeap="true"

<application
         android:theme="@android:style/Theme.NoTitleBar"
        android:allowBackup="true"
        android:largeHeap="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
       >


You are leaking resources (most likely the Drawable object). Try the tools in What Android tools and methods work best to find memory/resource leaks?


Where does the image source come from? Do you have a 9MB image in your drawables folder?

There's a lot of discussion on issues with Android's native bitmap memory management, e.g. http://code.google.com/p/android/issues/detail?id=10821, http://code.google.com/p/android/issues/detail?id=8488, http://groups.google.com/group/android-developers/browse_thread/thread/ed57849ef705d421/11af8362d77a8cf4?lnk=raot . I've had good luck explicitly invoking recycle() and System.gc() every time I am finished with a bitmap, e.g.:

private void changeImage() {
     if (mCurrentImage != null) {
          mCurrentImage.recycle();
          mCurrentImage = null;
          System.gc();
     }
     mCurrentImage = getNewImage();
}


First stop your application from crashing at run time by catching the OutOfMemory error at place which you think can generate this error as below:

try {

...

}
catch(OutOfMemoryError error)  {
    //decide what to do when there is not more memory available
}


You can fix the problem using opts.inSampleSize=2; or opts.inSampleSize=4

BitmapFactory.Options opts = new BitmapFactory.Options();
// opts.inJustDecodeBounds = true; 
opts.inSampleSize=2;    
Bitmap myBitmap = BitmapFactory.decodeFile(st_imagepath,opts);


Angel, there is a similar problem posted on StackOverflow here @ OutOfMemory exception when loading bitmap from external storage

And from there I inferenced SoftReference could also be an alternative for the solution .Do check the post it might prove helpful.


I made a couple of extensions to @hp.android's excellent answer:

  1. Instead of defining a RootView ID in each XML class, I dynamically find the root view using android.R.id.content.
  2. As @Mario Lenci says, AdapterView doesn't support removeAllViews, so I check the type of the view before calling removeAllViews().
  3. IMO it isn't a good idea to call System.gc() in every onDestroy call (e.g. this answer), so I've removed that.
  4. I've made a static onDestroy method that I call from onDestroy in all my custom Activity classes.
  5. I've added some extra error protection and logging.

Here's the code:

    public static void onDestroy(Activity activity) {
        View rootView = null;

        try {            
            rootView = ((ViewGroup) activity.findViewById(android.R.id.content))
                    .getChildAt(0);
        } catch (Exception e) {
            Log.w("Cannot find root view to call unbindDrawables on",
                  activity);
        }

        if (rootView != null) {
            Log.d("unbindDrawables", activity, rootView);
            unbindDrawables(rootView);
        }
    }

    /**
      * Utility method to unbind drawables when an activity is destroyed.  This
      * ensures the drawables can be garbage collected.
      */
     public static 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));
             }

             try {                
                 // AdapterView objects do not support the removeAllViews method
                 if (!(view instanceof AdapterView)) {             
                     ((ViewGroup) view).removeAllViews();
                 }
             } catch (Exception e) {
                 Log.w("Ignore Exception in unbindDrawables", e);
             }
         }
     }


A 1550532 byte allocation sounds big. I'm guessing your layout has a reference to a bitmap image of some kind, a PNG perhaps? What are the dimensions of this PNG? If it is really big and you have more than a couple of them you might just not have enough memory to load them all at once.

Also if this is triggered by the rotation remember that your Activity is destroyed and recreated so you might need to be careful of static references. Take a look at this Google blog post. You'll need to be careful of keeping static references to things in your code which may result in leaks
