I'm implementing an image cache for PNGs, downloaded from the web. Works well so far, besides that on images with a transparent background, get a light-green background, when they are read from the cache (external storage).
Tested on 3 devices, the problem was in 2 of them, a Samsung Galaxy and HTC desire. The third one, a Galaxy Nexus, has not this problem. The relevant parts of code: Save to file: FileOutputStream outputStream = new FileOutputStream(fileUri); image.compress(Bitmap.CompressFormat.PNG, 100, outputStream); outputStream.flush(); outputStream.close(); Read file: File file = new File(fullCacheDir.toString(), fileName); Download from web: DefaultHttpClient httpClient = new DefaultHttpClient(); HttpGet request = new HttpGet(urlString); HttpResponse response = httpClient.execute(request); InputStream is = response.getEntity().getContent(); TypedValue typedValue = new TypedValue(); typedValue.density = TypedValue.DENSITY_DEFAULT; Drawable drawable = Drawable.createFromResourceStream(null, typedValue, is, "src"); -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
