I'm using PdfRenderer above api 21 to display pdf in my app and I noticed that the quality of pages is very poor. I followed also google sample to use PdfRenderer and this is how I create Bitmap for page: //mCurrentPage is a PdfRenderer.Page and mImageView is an ImageView Bitmap bitmap = Bitmap.createBitmap(mCurrentPage.getWidth(), mCurrentPage.getHeight(), Bitmap.Config.ARGB_8888); mCurrentPage.render(bitmap, null, null, PdfRenderer.Page.RENDER_MODE_FOR_DISPLAY); mImageView.setImageBitmap(bitmap); I used ARGB_8888 because as far as I know, it's the best quality to display bitmaps.
