I wonder why I sometimes get an OutOfMemory Exception in mapView when scrolling around on map and zooming in to the max Zoomlevel? Is this a bug in the Zoomcontrols or MapView Lib?
Here the stacktrace:

When I use MapView in place of ImageView, there is no compilation error, but the app never launches on emulator. I followed the example given on android developer website.
When I use ImageView, it asks me to cast the ImageView object before getZoomControls(). But it is of no use.
Why zoomcontrols work with mapview well, but not with imageview? As zoomcontrols, mapview and imageview all are subclasses of view, I expected the example of mapview to work with imageview as well. Is there anything that I am missing?
How else do I use zoomcontrols with ImageView?
Here is my code snippet:

I had found a lot of stackoverflow post about save an Activity and the reload it.
My question: How can I have an Activity with an MapView and after reload the same mapview?
What is the best way to switch between activity and views?
I have done many of reverse engineering for other electronics in the past, Since Im new to android I was wondering before even wasting my time if is possible to port, or built a rom from sources or a phone thatis NOT External SD built in to a phone that it have the external sd built in.
Making it short can I try to reverse engineer the android code from a Nexus 5 (no ext_sd) to other device that have ext_sd built in?
If is possible where should I be looking to start trying making some development on this as I haven't done nothing close quite.
I am facing an Out Of Memory Exception while playing with the application for sometime. I looked in to HeapDump using MAT, and also monitored the heap through DDMS. But HeapDump looks good to me and DDMS heap size is well in limit. Still I am getting this Exception.
View 7 Replies View RelatedI really don't know why it's giving me this error... I load an ImageView with an image of 692kb .jpg, using scroll options, so you can scroll it around... the strange it's that when the mobile it's connected to the VM it's less possible to happen. So...how can I prevent this? is there anyway that I can free memory when starting the app? can I tell the system to free memory before loading the image?

I'm having a hard time resolving a crash report. It's an OutOfMemory exception that occurs during the setContentView in the onCreate of my main activity.
I just want to be sure I understood Android LifeCycle well :
1) The onCreate of my main activity is called once and only once during the life time of my application ? Is that correct ?
2) Just like for the big bang, before the oncreate of my activity, nothing exists for that activity, so memory consumption is zero, no objects exists right ?
So what can cause that sometimes, with random framework and devices, I get an OOM exception ? I mean if say my background image is causing this, it should blow up everytime, on every device, shouldn't it ? I mean the result should be reliable.
The background image is a standard jpg : 360*480 weighing 37kb, nothing fancy really :s

In my app, I am creating a bitmap from its colors code like this :

I create Android applications for my job. Eclipse is open all day and I am frequently editing XML files for layouts, etc. I find that creating/editing these XML files pushes up the memory use of Eclipse. Eclipse never seems to release any of the memory and eventually Eclipse tells me that there has been some sort of workbench out of memory error and I have to exit. It will not let me save or do much of anything after this point.
Is there a workaround for this? I don't want to have to exit Eclipse and start it up because of this memory issue. Why won't Eclipse free up its memory use? It just keeps going up. I am still having issues with running out of memory, the eclipse.ini suggestions did not fix it.
memory - after only 2-3 minutes I get Force Close and outOfMemory Error. I have only onCreate (I know, stupid, but I didn't knew for anything else as I started only few weeks ago) and inside I have...
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main);
many lines of code...manipulating with SQLite databases...
}
I have an Android app that in the onCreate() method, preloads a lot of graphics.
When I test my app on my HTC Aria and launch it, it runs fine. However, if I press the back button to exit my app, and then launch the app again, it crashes with an OutOfMemoryError: bitmap size exceeds VM budget. If I then launch the app for the third time (right after it has crashed) it launches fine. Then if I close and re-launch it, it crashes again with out of memory. It continues this every-other-time-crashing pattern forever if I keep trying.
I checked to see what life cycle methods were being called and onStop() and onDestroy() are both being called when I exit the app, yet I have a feeling that something is not yet being cleaned up and that by "crashing" the app when I try to launch it the second time, it somehow free's the memory.
Any thoughts on what could be happening or how to remedy this? Please let me know if you need me to post more info.
Info: My app is fairly simple and only has 1 activity that plays some frame animations.
Our app has some memory peaks, which let the heap grow to 13M. After the peak, there's 9M of free heap. Everything's fine until Bitmap objects come into play. Despite having 9M of free heap creating Bitmaps, which have only some 100k, now fail with a OutOfMemoryException!
My theory: Allocation fails if (Java) heap *size* plus external allocations (e.g. Bitmaps) exceed 16M, no matter that there is lots of free memory in the heap. The VM could shrink the heap, but actually does not. Would be quite a flaw in the VM.
Does anyone share this theory?
On the downside of this theory: I do not see anything appropriate (killing the process is probably not) an app developer could do to prevent those OutOfMemoryExceptions given that those memory peaks are legitimate and unavoidable.
I have a bitmap that I load from the SD card by allowing the user to choose a picture to display. Once the bitmap is created, I set the Bitmap in an ImageView:
CODE:.........................
This works fine. But, if I change the screen orientation from portrait to landscape, and back again a few times, I always get an OutOfMemory exception.
In onPause, I call mBitmap.recycle(), and then on onResume, I call the above code again to create the bitmap and set the ImageView. Since I'm recycling the image each time, how can I get an OutOfMemory error?
In any case, since that failed, I found a post that said to try using onRetainNonConfigurationInstance() and getLastNonConfigurationInstance(). See post http://stackoverflow.com/questions/3250987/save-cache-when-rotate-device/3252547#3252547. I changed my code to work this way, and I still get an error. Changing the code, I had the call to getLastNonConfigurationInstance() in onCreate(), and removed all code in onPause and onResume. provide some way to simply load an image, and then be able to pause and resume the Activity without running out of memory?
I have an application which fetches data from server and shows it in different lists in my application. I used the adb shell procrank command to find out the memory usage of my application It takes 10 mb for the UI (I have a single Activity ,but many layout files), And the data which comes from the server is stored in memory arrays for logical representation on UI (As well as database)and it takes 6 mb of the memory .So application's runtime size reaches to 16 mb and then many a times its crashing after that with OutOfMemoryException. Another major problem is that later for the next client release , the data comming from the server will be around 12 mb.. :( :( So i need to do a major restructuring in the App.I beleive that i cannot increase my App size from 16 mb to more So my question here is , can i have two seperate applications , one of which will fetch the data from the server and keep it in memory as well as database and another App will be used for showing the UI and it will do an inter Application communication to fetch the data and display it on the UI in this App. So the 1st App wil be a backgrond App which will handle Server communication as well as data storage , the second App will start this 1st App .

I'm able to set the animation to about 10-20 frames and it works great. But once i set it to about 30 frames...I get an OutOfMemory Error. I was hoping maybe someone could take a look at my code and maybe give an example of how I could achieve more frames? That would help so much i've been looking at this for hours > <

I am trying to set a different wallpaper for every home screen, but I get OutOfMemory issues. I have 5 Bitmaps which I am trying to overlay on a wallpaper Bitmap which is 5 times the display width. Using the code below I get OOM. The problem seems to be the first line of code which creates the large wallpaper Bitmap. My question is whether there is a way to do this (i.e. some way that takes up less memory, or someway to allocate more memory?).

I sometimes get bug reports that are caused by an OutOfMemory error. It happens when creating a bitmap, but I am pretty sure that it is not the bitmap size that is the real problem, because the instantiation of those images happens > 100.000 times a day without an error report. Those png images are of 4K size (on disk) anyway.
Those bug reports are very infrequent, but still I would love to get rid of them. I can't reproduce the memory growing over 10 MBs (actually way less) when using the app myself and monitoring the memory consumption in DDMS. I also, at no point in time, cache something or hold on to more than one item (article in my case) at a time, except in one list. There the list caches the visible components, which cannot amount to much too and is default functionality from the Android framework.

I have a list of 70 text items with image icons(which are stored in drawables folder).
If I launch application the first time and scroll the list slowly - the exception doesn't occur.
When the application is launched the first time and I scroll the list with 'fling' action the following exception occurs:

After that, if I kill the application with DDMS, start it again and scroll it with 'fling' action, exception doesn't occur. So the exception arises only if application is installed and launched the first time.
Here is the adapter I use for the list:

Is there a way to avoid the exception? Should I catch the exception and escape the memory somehow?
In my application I load a couple of images from JPEG and PNG files. When I place all those files into assets directory and load it in this way, everything is ok:

UPDATE: Tried both of these on real device - it seems that I can't load more than 12MB of bitmaps into whatever is called "external memory" (this is not an sd card).
I have to manage several Bitmap in a ListView where each row is composed by one thumbnail and one textview. This ListView can be very long, over 500 rows...
There are two problems I have to solve:
1) it is better if I cache all the bitmaps, maybe using SoftReferences in a HashMap. I've tried this way, but I noticed a strange behavior with the SoftReferences. It seems that the GC clean them too fast. Why?
2) In order to implement the cache correctly I'd also like to understand which is the best practice you suggest me to realize a "image lazy loading". For example... I'm thinking to load all the data for first and then to load only the thumbnails, but only those really visible on the device screen at the and of the scroll action.
I have been using a SAX parser for a while now to get data from various XML, but today i'm banging my head on a new problem with a hudge XML (compared to the previous ones . here around 12k lines) with a lot of repetitive items in it. Most of the time, the items are part of a block :
CODE:.............
The blabla part is of course changing...But, I would like to keep the structure of items (they are titles and subtitles). And for that, I append each blabla with a starting and ending tag <itemx>blabla</itemx>, where x is the position in the tree of items (1, 2, 3 or 4). The slightly problematic part is that with that, I'm creating thousands of useless objects and the garbage collector doesn't have time to clean after the parser, and the inevitable OutOfMemory comes in my face...I have no idea of how to deal with it; The best technique would be if I could take the whole content of <content></content>, but i'm not sure that this is possible with a SAX parser.

View 5 Replies View RelatedMy problem is my MapView becoming very laggy and so non-responsive at times, that Android thinks its hit deadlock and tries to close it.
I am adding 60 overlays to the map view and i originally thought that the icon size may be causing the problem by using up all the memory. When i decreased the overlay icon size, it did improve things, though it is still to slow to be usable. Has anyone experienced anything similar and have a workaround? There may be a better way of doing it other then extending the Hello MapView example.
How to get MapView API in android?
View 2 Replies View RelatedI have subclassed Overlay as LandMarkOverlay (and implemented an onTap(GeoPoint) method).
In the main activity I do this:
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
landmarkOverlay = new LandmarkOverlay();
//add the landmarkOverlay to the list
mapView.getOverlays().add(landmarkOverlay);
What else do I need to do so that when the user taps the screen, landmarkOverlay's onTap(GeoPoint) method gets called?

We are plannig to write a new music application from scratch. Also we want to uninstall the built-in music application to ensure only our application resides on the phone. adb ls /data/app command doesn't list built-in applications. So, I am unable to uninstall the built in music application without knowing its name. So, I am getting a feeling like built in applications uninstallation is handled in different way.
