I am tired of trying every possibility in stackoverflow and googled alot……
not getting what i want.

bt=BitmapFactory.decodeResource(getResources(), dressarray[indexdress],options);
//Background1 = getApplicationContext().getResources().getDrawable(dressarray[indexdress]);
bt1=Bitmap.createBitmap(bt);
dress.setImageBitmap(bt1);

i have this code in various if else conditions… dress in code is ImageView
there are lots of images on my screen..
there are 10 ImageButtons and for those i have 1 onClick method which performs above operation on particular ImageView by checking which button is pressed.

at last i call a method to recycle bitmap(which is my last variation before asking question) inside onClick.
call to that method is the last line in onClick

here is the method to recycle

public void callrecycle()
    {
        bt.recycle();
        bt=null;
        bt1=null;
        System.gc();
    }

now problem is i hav an emulator with HTC EVO screen density and resolution with platform 2.3.3 an a second emulator with density 180 resolution 320X480 and platform 2.2

on 2.3.3 i get an error

can anybody tell me the reason?
and please tell me how can i reuse recycled bitmap.
i don want to reduce the quality of bitmap.

the options i am passing have

inPurgeable=true
inInputShareable=true

Note: if i dont use Bitmap thing and directly write dress.setImageResource(dressarray[indexdress]);

the app works like a champ in 2.2 but closes with Out Of Budget on 1st click on 2.3.3
and dressarray[indexdress] is an array of images containing R.drawble.imgid and all are PNG images

    I solved this issue at that time by using downgraded images.

    You can avoid this error by using inSampleSize & inPurgeable in options.
    and reusing the same Bitmap variable and making it null after every use.

    call System.gc() wherever possible. it doesn’t call gc but gives hit that it can be started.

    inPurgeable will make ur bitmap object cleanable while doing gc().

    inSampleSize will downgrade bitmap so use a proper value.

    also you can resize your bitmap while creating so that it can reduce its size. use createScaledBitmap()

    Hope it help others.
