Hi Dianne, thanks for your reply. The problem is that I'm using RemoteViews.setImageViewUri(), so I don't have a bitmap object to set the density. The Uri I'm using is "content://..." which reaches my ContentProvider at the method openFile(Uri,String).
I looked at the Android source code and I see that ImageView.setImageUri() uses resolveUri(), and for the content scheme it calls Drawable.createFromStream(mContext.getContentResolver().openInputStream(mUri), null); which calls my openFile() method, which I implemented like this: public ParcelFileDescriptor openFile(Uri uri, String mode) throws FileNotFoundException { File file = new File(getContext().getFilesDir(), "MyFile.png"); return ParcelFileDescriptor.open(file, ParcelFileDescriptor.MODE_READ_ONLY); } I don't see where I can change the density to use. :( Thanks, Yuvi On Sat, Feb 18, 2012 at 2:19 AM, Dianne Hackborn <hack...@android.com>wrote: > Set the desired density of your bitmap: > http://developer.android.com/reference/android/graphics/Bitmap.html#setDensity(int) > > > On Fri, Feb 17, 2012 at 12:56 PM, YuviDroid <yuvidr...@gmail.com> wrote: > >> Hi, >> >> sorry to resurrect this post...but I got into a similar problem.
