View 4 Replies View RelatedAndroid : ImageAdapter And ListView (java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget)
Jun 15, 2010I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds.
I tried clearing cache, canceling cache, etc. - nothing helped.
I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them.
Android : How To Guestimate Available Bitmap Memory On A Device
May 13, 2009Part of my application allows the user to color-correct images. When i open an image for editing, i'd like to know what, more or less, the available bitmap memory is for the device that the app is running on.
For the G1, the limit is use is about 6MByte (about a full-size image that can be taken by the phone (3MPixels) with 16 bit color ==> 6MByte). If i try to open anything larger, i often get an out-of- memory exception. Limiting it to 6MByte reduces these OOM exceptions by a great deal. However, i can see future devices having more memory available because (as one of the reasons) they can take larger pics (e.g. 5MPixel or something).
Right now, my app just uses a hard-coded limit of 6*1024*1024. Is there a way to make this variable, to future-proof this by examine the device my app is running on. If so, how?
Android :: Various Options To Parse A XML In Droid Mobile Device?
Oct 27, 2010I have a huge set of xmls(2000 files each having 500 lines) to be parsed in Android for fetching the information from it. All the files will be present in the device. I had this to be done in iPhone and i accomplished it by converting all the XMLs to PLIST files. The PLIST processing in a iOS was faster than parsing a XML in iphone. Similarly for android is there any options available? or What are the best way to parse those XMLs in android as i feel the same problem we had in iphone(performance incurred in parsing) will be here also?

View 2 Replies View RelatedAndroid : Crop Bitmap Without Reading Entire Bitmap / Cannot Read Image Into Memory
Jul 21, 2010I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
Android :: Create Mutable Bitmap From Camera - Draw Another Bitmap On Top - And Save It
Apr 2, 2009I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.

Please advise. I don't want the mobile device to get any slower.

General :: How To Get Java Source Code For Device
Jul 5, 2012I followed evilisto's guide to make honeycomb style lockscreen.I could get the framework layout working, but since I didn't know how to get java source code for my device, so I just decompiled framework2.jar and modified MultiWaveView.smali(since framework.jar doesn't have this file, I had to decompile framework2.jar), compiled and odexed it.But the radious of chevron is too big and animation speed didn't change.What should I modify to change animation speed and radious of chevron?
I changed the values to extremely high value, but it seems framework2.jar and odex doesn't work for lockscreen chevron at all..
