@Drezden
Your correct i am using larger number of images added as child view of
LinearLayout which is a child view of HorizontalScrollView,
Like OOM issue is happening at different number of images decoded from
BitmapFactory on different devices like Google Nexus it is after 160
images , Xoom 253 images and so on.
For decoding i am already using options and calculating inSampleSize
only not inTempStorage(will it add any improvement if i use it?).
Also i have cache that has soft reference to improve efficiency in
terms of number of images decoded because i am recycling bitmap, but
eventually it will crash due to OOM.
thanks
