bitmap size exceeds VM budget by calling new Activity

Question

Hi Lets say when i call Activity A to Activity B

below is my code become

     Intent i = new Intent(TemplateList.this, PictureEditor.class);
     Bundle b = new Bundle();
     b.putString("Key", "2");
     b.putString("Index", imagepathString);
     i.putExtras(b);
     v.getContext().startActivity(i);
     System.gc();
     Runtime.getRuntime().gc();
     finish();

Because of in Activity A there are so many objects (so many images) loaded so i am clearing that all objects by System.gc(); Runtime.getRuntime().gc(); will be cleared and also destroying activity so no any object will be stay allocated :)

and from Activity B i am going call to Activity A

        btnTemplate.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            startActivity(new Intent(PictureEditor.this, TemplateList.class));
            dg.dismiss();
            if (bmp != null) {
                bmp.recycle();
                bmp = null;
            }
            System.gc();
            Runtime.getRuntime().gc();
            finish();
        }
    });

//Here also i m calling System.gc and Runtime.getRuntime.gc and destroying activity but do not know why if activity A starts than i m getting

below error

Can any body solve my problem :(

your heap size is increasing annoyingly debug the Code and Make Break points where you think it increases the size of the heap — Usman Kurd, Dec 19 '12 at 07:46

Its never a good practice to manually call System.gc(); or Runtime.getRuntime().gc();. The better option is to resize/scale your Image according to the screen size using inSampleSize or maybe scaledBitmap(). You can check my answer here which will give you idea that how you can resize/scale the Image before loading it into memory.

but Lalit ya i am already using options.inSampleSize and doing in sample size image but my actual question is activity A which is loaded with no of images, and although it is loading properly on first time but in second time it is going to exceeding memory size why? i am already destroying from stack and releasing all the objects then why this is happenig – Siddhpura Amit Dec 19 '12 at 10:04
maybe because something is still there in memory that is causing memory overloaded. Some static data might be there. – Lalit Poptani Dec 19 '12 at 10:06
but Lalit i have not used any static data :( You are right because when activity starts again it loaded with more memory i have tested – Siddhpura Amit Dec 19 '12 at 10:09
probably there is some static data which is not releasing your memory due to which you are getting the exception. – Lalit Poptani Dec 19 '12 at 10:18
I have posted whole class can you check this class there is no any static data http://stackoverflow.com/questions/13951575/bitmap-size-exceeds-vm-budget-by-starting-activity-again – Siddhpura Amit Dec 19 '12 at 11:38

Calling those methods won't work, those methods just say to the GC that "if you want you can run now".

Basically look for those problems:

Isn't the bitmap too big? -> Rescale it to the minium required size in your app.
Are you copying the bitmap too much?
Aren't you leaking the bitmap by leaking the context of your Activity B?

It could come from many places but I would try to downscale it to the minimum required size in your app first.

Try to Scale Down The Images You can use this

public static Bitmap getResizedBitmap(Bitmap image, int newHeight, int newWidth) {
    int width = image.getWidth();
    int height = image.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // create a matrix for the manipulation
    Matrix matrix = new Matrix();
    // resize the bit map
    matrix.postScale(scaleWidth, scaleHeight);
    // recreate the new Bitmap
    Bitmap resizedBitmap = Bitmap.createBitmap(image, 0, 0, width, height,
            matrix, false);
    return resizedBitmap;
}

and from here you can calculate the Size of the image you are getting

but Usman ya i have use this method and resize image but my actual question is activity A which is loaded with no of images, and although it is loading properly on first time but in second time it is going to exceeding memory size why? i am already destroying from stack and releasing all the objects then why this is happenig – Siddhpura Amit Dec 19 '12 at 10:04
try to debug your code with break point and get the Heap size how it is increasing – Usman Kurd Dec 19 '12 at 10:08
