After 3 days of struggle i found a solution for not increasing Heap memory by using this

i replace all my ImageView like this

<com.example.util.SingleShotImageView android:id="@+id/grid_image" android:layout_width="170dp" android:layout_height="240dp" android:adjustViewBounds="true" android:layout_centerInParent="true" />

Using this class i use to clear the Image bitmap heap size in onDetachedFromWindow function

public class SingleShotImageView extends ImageView { public SingleShotImageView(Context context) { super(context); } public SingleShotImageView(Context context, AttributeSet attrs) { super(context, attrs); } public SingleShotImageView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected void onDetachedFromWindow () { setImageDrawable(null); setBackgroundDrawable(null); setImageBitmap(null); System.gc(); } }

now it works fine and my heap memory remains

Grow heap (frag case) to 11.719MB for 8192016-byte allocation

Hi, I change my code to exactly what you said but the problem is onDetachedFromWindow() method never calls in activities while calls when I'm replacing fragments! So, my app still crashing on activities.
Oh GOD , I need It , Some Nights Didn't Slept To Find Solution , onDetachedFromWindow method Clean Custom ImageView
