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 :: BitmapFactory: Decoder - Decode Returned False

Oct 27, 2009

For my current application I collect images from different "event providers" in Spain.

However, when downloading images from salir.com I get the following logcat output: 13970 Gallery_Activity

I Fetching image 2/8 URL: http://media.salir.com/_images_/verticales/a/0/1/0/2540-los_inmortale... 13970 ServiceHttpRequest

I Image [url] fetched in [146ms] 13970 skia D --- decoder->decode returned false

Searching for that error message didn't provide much useful results.

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 :

Code:

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

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:

Code:
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());

[code]....

Android :: BitmapFactory.Options - Exceeds VM Budget

Nov 5, 2010

I've been reading about performance issues decoding Bitmaps and have received the OutOfMemoryError "Bitmap exceeds VM budget" issue when I would expect to not be out of memory and read online that this is a common problem referred to as a bug in the framework by many devs. Typically, I get the error mentioned above on my second pass. Let's say I load a somewhat sizable Bitmap successfully and then recycle it and even set the ref to null. When I call this same method a second time that does the work of loading my Bitmap(s) into memory...

I've read on previous posts here and elsewhere online that there are a few things that can be done with BitmapFactory.Options (for instance, providing an input buffer explicitly). But, before proceeding blindly in using what I've found, I'm hoping someone with more knowledge of these classes can shed a little more light...........

Android :: BitmapFactory.decodeStream Returning Null When Options Set

Mar 23, 2010

I'm having issues with BitmapFactory.decodeStream(inputStream). When using it without options, it will return an image. But when I use it with options as in .decodeStream(inputStream, null, options) it never returns Bitmaps. What I'm trying to do is to downsample a Bitmap before I actually load it to save memory.
I've read some good guides, but none using .decodeStream.........................

May 5, 2009

I want to decode high resolution pics something like 8 mega pixel images and view it. when I try to decode them I get out of memory exception. Decoding of single 8 mega pixel also fails . From the Imagamanager code and other post I could use BitmapFactory.Options inJustDecodeBounds I could get a scaled down version of the Image . code...

Is there any way to decode part of the Image and fill it on the screen and by scrolling decode other region of the image and display it.

Android :: Cannot View Images From SD Card On Emulator

Jan 27, 2009

I have just started learning to develop for the G1 after two weeks of joyful us of my actual G1. I have however, come across a stumbling block in my development learning. I have successfully emulated an SD Card on the emulator. However, now, after saving an image from the browser to the phone I cannot 'View Picture' or 'Crop Picture' for a wallpaper. All I get when trying to access the picture is an error message saying: "The application Camera (process com.android.camera) has stopped automatically. Please try again." Does anyone know why this is or how to get around/fix it?

ImageAdapter adapter = new ImageAdapter (mCursor, this);
Log.i(TAG, "displayGallery(), adapter = " + adapter.getCount());
mGallery.setAdapter(adapter); mGallery.setOnItemClickListener(this);

Android : Where Should Store Images / Doesn't Have An SD Card?

Jun 19, 2010

There are a few G1 users reporting that my app won't display images. I can only imagine this is because they don't have an SD card. My app is heavy on images. Is it appropriate to store images on the internal memory? I don't even know if there'd be enough space.

I'm working on an Android application that needs to look at what images a user has stored. The problem is that if the user has the sdcard mounted via the USB cable, I can't read the list of images on the disk.
