I'm writing a Music application and I have already gotten the album arts. However, they came up in various sizes. So, how do I standardized the size of the returned bitmap ?

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

View 2 Replies View RelatedI've problem with memory of the bitmaps, I'm creating a lot of bitmaps and then releasing them by recycle() and after many retries I get:
java.lang.OutOfMemoryError: bitmap size exceeds VM budget
How to get rid of this? The problem is that even if i close the activity (call onDestroy()), in next program run the bitmap memory is still allocated! (I've also android:clearTaskOnLaunch="true" in my manifest). This is horrible. Can anybody help me with that? I suspect that every application using BitmapFactory.decodeResource must get this exception in some call! Do you have any idea what's going on?
I have the following code which I tried to build a Bitmap from an input stream and I want my output bitmap to be 20 x 20:
BitmapFactory.Options opts = new BitmapFactory.Options(); opts.outHeight = 20; opts.outWidth = 20;
InputStream stream = // an input stream to my image Bitmap bm = BitmapFactory.decodeStream(stream, null, opts);
But when I tried it, I do get a bitmap from the inputstream, but it does not scale it to 20x20 which I specified in the BitmapFactory.Options.
It immediately has trouble with memory. In the LogCat this error is displayed, java.lang.OutOfMemoryError: bitmap size exceeds VM budget. I'm using recycle () and System.gc () but I get the same error. My application, is pressing a button switches to the next image and the images are 854x480 Loading images from the SD Card. show the images as follows
Bitmap imageB; ImageView imgV;
imageB = BitmapFactory.decodeFile ("sdcard / img.png"); imgV.setImageBitmap (imageB);
Release is as follow.
@ Override protected void onDestroy () { super.onPause (); imageBG = null; System.gc ();
}
How can I determine/calculate the byte size of a bitmap (after decoding with BitmapFactory)? I need to know how much memory space it occupies, because I'm doing memory caching/management in my app. (file size is not enough, since these are jpg/png files).
View 1 Replies View RelatedI am doing the following in my app, which at times results in the above error.
Action 1: Button on Main activity calls all pictures using ACTION_PICK (results in a thumbnail view of all pictures on my phone). User picked image (URI) is then passed over to next activity where the image is displayed (ImageView) full screen. When I hit back, I go back to the main activity. If I try to open all pictures and pick a picture again, I get a FORCE CLOSE and the logCat data says "OutofMemoryError: bitmap size exceeds VM budget.
Action 2: I get the same error and FORCE CLOSE when I try to rotate the full-sized picture by changing phone orientation back and forth.
What am I supposed to do to save memory? I can't change the use case of my app... the user has to follow the above steps. How can I free up memory without having to change anything in my app.
In my application i have a functionality where a user can take photo and poet it to a web server or select a photo from galerry and upload.
So initially i used to get below exception for the very* first time* i used to select a photo:
Android: OutofMemoryError: bitmap size exceeds VM budget. then i used:
*options.inSampleSize = 2;*
Now the problem is im still getting the same exception *the only difference is im getting exception after 2-3 times.*
i.e im able to upload 2-3 (one by one) photos and then i get the exception. any suggestions?
I am using bitmap image that i have to rotate on fling. its actually a circular image that will act like a spin wheel. so image resolution is like 1000 x 1000 but when i rotate this image and redraw it android give me an exception " java.lang.OutOfMemoryError: bitmap size exceeds VM budget "
View 2 Replies View RelatedI'm writing game with a large amount of .png pictures. All worked fine. Than I added new activity with WebView and got memory shortage. After that I made some experiment - replace game .png images with ones that just fully filled with some color. As result memory shortage had gone.
But I suppose that Bitmap internally hold each pixel separately so such changes should have no effect. Maybe this because of initial images have alpha channel and my test images have not it?
But actually question is: Will decreasing .png images files sizes make some effect on decreasing usage of VM application heap or not?
While I'm trying to resize a photo (originally on a sd card), grabbed using :
InputStream openInputStream = contentResolver.openInputStream (photoUri);
I got the following stack trace when calling : Bitmap bitmap = BitmapFactory.decodeStream(openInputStream);

Do you know an alternative way to resize a picture ? without calling BitmapFactory ? and without getting such an exception ? Thanks in advance for your help Anthony
Posted my problem here too HERE: A beginner..Im doing a school map app.
First of all I have background with 4 buttons ( level3, level4, level5, level6) I try and click all the buttons, normally after clicking 3 of it, the next one will crash.(each level button goes into a level map, whereby clicking the room image buttons, I will enter into the gallery-imageswitcher)
I have at least 5 imageswitchers in each level maps,so that about over 20 imageswitcher galleries overall.
I did all my stuffs using DRAWABLES instead of BITMAPS.. I have tons and tons of images (because its a school map, show all the photos in my school, and all those backgrounds and imagebuttons)
I did some research, and those who have problems are those using bitmap. Some of the ways that can be solved is system.gc();, and bitmap.recycle...(not so sure how to use it though)
In my main background - starttour.java Code...
PS: I have tons of images in the app; I have at least 5 imageswitcher gallerys in each level, so that kinda adds up to over 20 imageswitchers in my app.
I have an ImageView that contains a bitmap. Now the bitmap can change size within a known range. This makes the surrounding views to relocate which I want to prevent. I've tried setting margins and padding for the ImageView but without success.

View 1 Replies View RelatedI'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.
Along with Android being 'open', what about some standardized form factors? Would this help the 3rd party market peripherials? I hope Google, with the Nexy, keeps the form factor so that the Nexy 2 will be the same. That way we get more, and possibly more interesting devices from 3rd parties.Not sure if form factor is the right term to use.

View 1 Replies View RelatedI 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.

Input Stream is = getContentResolver().openInputStream(data);

I 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.
I have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.
CODE:.....................
I want to draw a shape(many circles particularly) into a Specific Bitmap. I have never used canvas / 2D graphs etc. As i see it i create a Drawable put the bitmap in it then "canvas-it" to the shapes i want etc.

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.
