hi guys,
sorry got involved in something else and just didn't look back
here,....
this is what was happening:
i hav an action_pick where the user picks an image and the resulting
URI is used to display the image as is full-size on the imageview.
This action wud cause an outofmemory error.... and also when I change
orientation.
after reading through a couple of other posts, I used BitmapFactory
and scaled the original image before displayin it on imageview. The
code is shown below. It is self-explanatory. While the scaling is
done, I wanted to still use the original image file for later part of
my app, which is what I did.
try {
InputStream is = getContentResolver().openInputStream(
selectedImageURI);
BitmapFactory.Options opts = new
BitmapFactory.Options();
Bitmap bitmap;
opts.inJustDecodeBounds = true;
bitmap = BitmapFactory.decodeStream(is, null, opts);
System.out.println("ht" + opts.outHeight);
System.out.println("wt" + opts.outWidth);
System.out.println("mime" + opts.outMimeType);
BitmapFactory.Options ops2 = new BitmapFactory.Options
();
WindowManager win = getWindowManager();
Display disp = win.getDefaultDisplay();
int width = disp.getWidth();
float w = opts.outWidth;
int scale = Math.round(w / width);
ops2.inSampleSize = scale;
is = getContentResolver().openInputStream
(selectedImageURI);
bitmap = BitmapFactory.decodeStream(is, null, ops2);
ImageView imageview1 = (ImageView) findViewById
(R.id.imageview);
imageview1.setImageBitmap(bitmap);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Hope this helps.
Thanks,
Abhishek
