Hi, i have used this even but this doesnt make any difference on low end devices we can see the difference on high end devices like S3 but we wont get the issue of heap on those devices, using this will make lots of drawbacks for the device environment, please refer to http://stackoverflow.com/questions/7596950/android-heap-memory-increasewhich has the same issue of larger heap Thanks Shiva On Wed, Nov 7, 2012 at 9:24 PM, bob b...@coolfone.comze.com wrote: Have you tried this: android:largeHeap = “true” On Monday, November 5, 2012 2:15:05 PM UTC-6, sourabh deshpande wrote: Hi, 1) I am developing an application which has very high quality image contents.

[android-developers] Re: Bitmap issue and Webview rendering issue in ICS
Hi
I had worked with the same issue for longer period but i haven't find the
solution to work on images of longer width and height(BITMAP),
finally i have used it by resizing the image,
if we see the size required to create the image it need width*height*4
bytes which is not supported for all the devices
the supported size for all the images is 512*512
the solution i have suggest for larger images is as follows
yourSelectedImage = BitmapFactory.decodeFile(path);
Float Ratio=(float)
((yourSelectedImage.getWidth()*1.0)/yourSelectedImage.getHeight());
Float byratio=480/Ratio;
if(yourSelectedImage.getHeight()490||yourSelectedImage.getWidth()490)
{
yourSelectedImage=Bitmap.createScaledBitmap(BitmapFactory.decodeFile(path),(int)(byratio*1.0),
640, true );
}
the resultant will be re sized with the same ratio,
this is the main reason why all the apps of photo editor have a negitive
rating saying low image quality
Thanks
Shiva,
