I have a very small activity that must show an image.
If picture is not very small (for example 1.12 Mb 2560x1920) it produces out of memory on change screen orientation. I tried getDrawable.setCallback(null) but no luck.

But i diden't see nothing [simply a void button]
I tried to show a picture in local file system in a imageswitcher. But I could see nothing but a black screen in fact.
Here is my code:

When I debugged it, it showed me the message "resolveUri failed on bad bitmap uri: file:///data/data/com.Android.Hust.PoliceMap/app_c/2.jpg".
How to solve this problem and show my picture in the Emulator?
I'm using ImageView.setImageURI() to render an image that has been previously downloaded from the Internet. It works fine, but I haven't understood whether the call is blocking or not. In my code, I've implemented a background thread to download the bits, in the meantime a placeholder is rendered, and as soon as a download is complete, setImageURI() is called. This approach is used both for a Gallery with thumbnails and for a single, large rendered with ImageView. The thing is working, but I see that the application freezes for a while when a download has been completed and setImageURI() is called. Which make me wonders whether I'm using it properly.
For the record, I know that the images I'm downloading are larger than I need (at least initially); that is, they are much larger than the thumbnail and the large viewer. Since images, once downloaded, are stored locally forever, I should probably create some smaller-size previews in background and then pass them to Gallery and ImageView? Would that make the UI really more responsive?
I'm having a problem with setImageURI on my ImageView objects. I was using setimageResource(R.drawable.x), which was working fine, but now I'm trying to change over to using URIs so that I can be more flexible about my image source (not constrained to pre-packaged images).
I'm using ImageView.setImageURI(uri), where uri is (for example android.resource://com.example.hellogridview/2130837520, which I created by doing Uri.pars ("android.resource:// com.example.hellogridview/" + R.drawable.x). I took this method from my MediaPlayer, where I created URIs for R.raw wav files from this path.
It's not throwing any errors that I can see, but it's just displaying blank images. The images are ~150px each way and I'm displaying them about half size - would that cause a problem?
I am displaying images and some text in a list view with an adapter. The images are pulled from the web, then cached locally and displayed. The images are already small (60px square), and I know their size, so I'm using the advice from here suggesting I use setImageURI instead of decoding the bitmap. The class that does the work is a modified version of Fedor's ImageLoader
The code attaches a stub drawable to the ImageView until the desired image is downloaded from the web, then loads the cached file from the sdcard. In Android 2.2 this works just fine. It's fast, and I don't get OOM crashes. On 2.1, though, I get the following error:

i have a aplication on the android market, in wich exceptions and errors are catched and sent to me by acra. But i receive quite a lot out of memory errors.. In different kind of classes...some my app, some general java.. Does this always mean there is a problem in my app, or can it also be the phone ran out of memory due to a other process? Will users also get a fc dialog?.....................
View 7 Replies View RelatedIn my application I change layouts very frequently with most of the user interactions. Each time when a new layout is drawn, the applications memory size is increasing. I can see this in DDMS. This is absolutely fine. I have analyzed my application with memory analyze tool and it shows that there around 42 Table layouts at some point of time and this number increase as user does more interactions with the app. Now my question is why doesn't the GC collect the stale layout objects. Does GC collect on UI widgets also??? I feel it does but can any one tell me what may be the reason for GC not collecting my UI elements.
View 4 Replies View RelatedI have a couple of worker threads in my app which I stop and restart during onPause() and onResume(). I use a method that clears all the reference to and from the threads when stopping. However ThreadGroup is still retaining a reference to my threads and causing a small memory leak. After pausing and resuming my app about 40 to 50 times I will then get OutOfMemory Errors when loading bitmaps. Allthough this doesn't effect most of my users I do get occasional reports of crashes. How can I remove the references to my threads from ThreadGroup so that GC can do it's job.

I want to display pictures into an ImageSwitcher and change image every 3 seconds. I instanciate a Thread that call the setImageURI(URI) and I schedule it every 3 seconds. It does not update the view and I don't know how to do it. If I call the same code that call the setImageURI() from the OnClickListener of the view it works! Do you know why and how can I make it work?
View 3 Replies View RelatedI am running into a very weird thing. I have an ImageView, and when I call setImageURI with an image, it seems to change the size of the image view.
CODE:..............
The default image is 195 x 195, i am trying to set the image to be 200 x 200, after setting the image using setImageURI, i get the dimensions back and it says it's 48 x 48.
I have tried a bunch of different android:scaleType parameters, and I couldn't find anything that worked.
I also tried explicitly setting the size (layout_width="200px") and it seems to work.
I have a view that I am drawing to a bitmap, saving to disk and then putting in an ImageView via setImageURI. However, when the image is displayed in the ImageView it is not being shown at the correct size. It is about 1/3 smaller than it should be. I'm guessing that this is a density issue, but I can't figure out what's going wrong (my emulator is WVGA).
View 2 Replies View RelatedI have an application here that has a feature of showing a POI on the map. It's only one POI and it is only drawn when it's actually within the visible screen area. It works perfectly for a while but if I play around zooming in and out and dragging, it will eventually crash. According to Logcat, the reason is always an OutOfMemory error.
At first, I thought it was a bug on the Google Maps API. After some researching and seeing some Romain Guy posts, I was kind of convinced that I had done something stupid on my app that kept me running out of memory from time to time. Then I ran some more detailed tests with Heap Analyzer (Eclipse) on and I saw that even though I had 2+, sometimes 3+ megabytes left of free memory, I was still getting those annoyings Force Close messages caused by OutOfMemoryError. Most of the times it crashes when trying to alocate some 614kb chunk of memory regardless of how much I have left.
This problem happens a lot on Nexus One 2.2.1 and on HTC Evo 2.1. After some little testing, I got no crash neither on G1 1.6 nor Samsung Galaxy S i9000 2.1. But I cannot say for sure the G1 and Galaxy will not show this problem after more testing. I can only think of a memory fragmentation problem. I hope this problem has a solution. I will also be glad if I can just catch this error and prevent the app from crashing.................
I was reading in some other posts that some developers have the same Problem, but till now, no solution. its about the gallery: I have a string array with photos, but when the gallery does show the 2nd Picture it crash with:...............
View 7 Replies View RelatedI'm running into OutOfMemoryErrors when allocating bitmaps. This is not something I can reproduce with emulators, and has been reported by a few beta testers with the HTC Incredible. I'm not sure I can solve this directly, and my best hope is to follow best practices for bitmaps and memory thereof. But looking for those best practices based on groups archives left me with more questions than answers. If anyone has a chapter about this in their book, I will buy the book. Here are the things I've mulled over so far:
1. I have a bitmap for a drawing buffer. It is about 3-4 megabytes on some devices. This is the biggest bitmap I have, and without it, I wouldn't be able to much of anything useful in my app. I am assuming that it would not be useful to use inPurgeable if this is a bitmap that is drawn into. Is this true?
2. Next biggest in the hierarchy are some bitmaps that are about 22K bytes and 256K unpacked. Since I believe about 25 of these might be used at one time, I have a cache with a size of 25. I am careful to use BitmapFactory.Options.InPurgeable, so I believe that could make them take only 22K each, but I don't see that as guaranteed. Maybe they are taking 256K each, which would put me in the danger zone. As they are cycled out of the cache, I call bitmap.recycle(). I think this a good practice. Is it?
3. Next are some resources with icon size 32x32 pixels. There are about 50 that could be used or reused. If I use code like this:
Drawable s = mCtx.getResources().getDrawable(R.drawable.symbol_icon);
Where s is a local variable to rendering. Suppose I call this 37 times. Am I to assume that Android will do something smart like create only one bitmap for this resource even if it is used 37 times? Or am I to assume that Android will do something stupid like create 37 bitmaps and keep references in an obscure location that will prevent garbage collection? Do I need to get more access to these bitmaps and do something smart myself?
4. Finally are some other icons used for menus and ImageButtons. Most are declared in layout files - so I don't touch the bitmaps directly.
I'd like to make my memory usage more efficient, but don't want to spend time on things that will amount to shuffling chairs on the Titanic. And how do I best measure this usage? Interestingly enough, I've tried using the Allocation Tracker and it says I haven't allocated a single bitmap. In light of the above, I don't think that's right.
I was using ADT for debugging and then I get this Internal error: out of memory error
Is there any way to avoid this?

I am trying to do repo sync and every time I get this error. fatal: Out of memory, malloc failed fatal: index-pack failed
View 2 Replies View RelatedWe are also having occasional problems with OutOfMemory errors in createBitmap. It tends to happen after a few orientation changes when we are allocating the backbuffers. I have made it so that it calls recycle() on the old bitmaps (if any exist) and does a System.gc() before allocating the new backbuffers. What we are doing is allocating a backbuffer that is twice the width and height of the screen so that we can quickly zoom in and out.
With a 854x480 screen this would presumably be 6.25MB in size. The problem as I see it is the 16 or 24MB maximum heap size per process. This is unreasonably small, especially on devices that have 512MB of RAM. Ideally the max heap size should be something like 64MB, or perhaps allow apps to request a larger heap size from the user.
