BitmapFactory - (decode Returned False) For Internal Image Files Extracted From Zip

Apr 19, 2012

Need to display images downloaded and extracted from a zip into the "/files" directory of the app. the images are getting in there properly as far as i can tell - i am able to extract them from the emulator and view/open them from my desktop. but every attempt, every variation of code i have found and tried so far has failed (Tag: skia / Text: --- decoder->decode returned false).

My latest construct, which does work for image files downloaded separately and uncompressed :


String imgFile = new File(getFilesDir(), "myImage.jpg").getAbsolutePath();
ImageView myImageView = new ImageView(this);
Bitmap bm = null;
bm = BitmapFactory.decodeFile(imgFile);
} finally{

And here is the construct i am using to handle the zip extraction. I assume this is where the problem lies but i am clueless as to what i could possibly do differently and to what effect:

ZipInputStream zis = new ZipInputStream(fis);
BufferedInputStream in = new BufferedInputStream(zis, 8192);
ZipEntry ze;
while ((ze = zis.getNextEntry()) != null){
File dest_file = new File(getFilesDir(), ze.getName());

Android :: BitmapFactory.decode And Exit Data In Images

Oct 19, 2010

I'm downsampling an image via BitmapFactory.decode then base64 encoding the bytes to ship to the server. (long story on the latter part of that formula) It seems this process nukes all Exif data in the image data. Am I approaching this the wrong way or is this a fact of life?

Android :: How Can Check If Returned Location Is Reliable

Jan 4, 2010

I know how to get the calculated GPS position via getLastKnownLocation (). As tests show, this function really always returns the last known location, so it doesn't matter if there is a gps fix available.

How can i check if the returned location is reliable? I tried it with getAccurracy(), but this function even returns a accurracy although no gps fix is availavle (anymore). Is there a possibility to get gps dop values? Used SDK is 1.6.

Android :: BitmapFactory.decodeStream Returns Null

Oct 3, 2009

I have an activity which performs an image search, the results (URLs of thumbnails on the web) are rendered in a GridView. My GridView adapter class delegates creating the actual Bitmaps to an AsyncTask that loops to sequentially fetch the image content from each URL using HTTPClient, and creates the Bitmaps using:


I found that the above method sometimes returns "null" silently instead of creating a Bitmap. The occurrences appear to correlate with larger stream sizes (I check this by logging entity.getContentLength()). However, if I put a breakpoint just prior to the decodeStream call & then resume immediately every time I hit it (i.e. pause briefly on each iteration), the Bitmaps are created perfectly every time. All the images are quite small (most <10K), so the download & decodeStream happens fairly quickly. There are never more than 10 images processed in one AsyncTask.

Android :: Image Scaling By BitmapFactory.decodeResource()

Sep 17, 2009

I can't wait to try out the new 1.6 goodies, but first I'm retargeting my existing applications, and I decided to start with Daisy Garden. Changing to android:targetSdkVersion="4" caused the application to segfault on startup and discovered that the BitmapFactory.decodeResource method now performs scaling based on screen density. In this case the behaviour is unwanted - I'm loading a set of masks that are scaled later during composition. So I've quickly inserted the following method, which seems to perfectly mimic the previous behaviour:

private Bitmap loadBitmap(int resId) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inTargetDensity = 1; options.inDensity = 1; return BitmapFactory.decodeResource(context.getResources(), resId, options);
