@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 On Aug 26, 8:42 am, Drezden <[email protected]> wrote: > Are you loading a large number of images into your > HorizontalScrollView? > > If so, then you are probably running out of memory from the Bitmap > creation process.
