Android :: Will Code Cause Memory Leaks?
Aug 3, 2010Will the code cause a memory leak? Essentially I switch between various layouts in my application using setContentView(), and I have member variables of my activity that maintain references to various views (buttons/text views) on the layouts. Am I correct in thinking that if the activity class has a reference to a button and then changes layouts the layout wont be garbage collected because it will still hold a button reference? If this is the case, can I just null the button variable before changing layouts?

May 20, 2010When start Activity A, I found the memory usage of application is about 5MB. Then start Activity B from A via startActivity. In Activity B, I created a thread, and traverse file system in this thread, after traversing completed, call finish() and to return to Activity A. At this time, I found the memory usage of application is about 8MB (GC is forced before check memory usage). How to find Where memory leaks? By the way, I checked the memory usage with DDMS.
View 5 Replies View RelatedAndroid :: List View And Memory Leaks
Oct 23, 2010I have a very simple application which has a problem with getting ListViews to be freed by the GC. i have a ViewGroup which has a ListView. When the page with the ViewGroup no longer has any references to it, and I force a GC, the ListView is not freed. The project in question is quite small and can be found at http://gabysoft.com/download/MemoryLeak.zip. If you run it, the first page has a button and a ListView (which has no items so you cannot see it). When you press the button it switches to a second page which has just a button. When you press the button on the second page, it creates a new ViewGroup and ListView and sets that as the current view. Thus, every time you switch pages, a new ViewGroup/ListView is created, and all references to the old one go away. Hence the old one should be GC'd. However if you switch views 20 times and then force a GC you will see that the ListViews are never freed (i.e. their finalize method (which is logged) is not called). Now here is the really weird part. This happens ONLY if I build my project using Eclipse. If I use Ant to build and install the project, the ListViews are all freed when I do a GC as you would expect. Why would the Eclipse version exhibit this behavior?

Android :: AppWidgets - Reusing RemoteViews Instance Leaks Memory?
May 21, 2009I'm writing a widget. Currently, I'm have a simple ImageView, and calling RemoteViews.setImageViewBitmap(). I'm using a service to do the updates.
I thought it might be a good idea to reuse an existing RemoteViews instance, so I'm only querying it the first time around, and subsequently simply call setImageViewBitmap() with the new image.
This works well initially, but after some time I first start getting "!!! FAILED BINDER TRANSACTION !!!" errors, and later, an OutOfMemory exception.
Simply creating a new RemoveViews instance every time works flawlessy on the other hand. I'm just curios why that would be, any ideas?
General :: How To Find Which Apps Cause Memory Leaks
Apr 22, 2013Any user friendly android app which can effectively show which apps cause memory leaks on a phone?
I can only find developer tools to detect memory leaks within apps like Eclipse MAT. Sadly I'm not a developer so I would rather prefer just a list of apps to uninstall and not the exact cause of memory leak within a specific app.
Android :: Android Tools And Methods Work Best To Find Memory - Resource Leaks
Jul 18, 2009I've got an Android app developed, and I'm at the point of a phone app development where everything seems to be working well and you want to declare victory and ship, but you know there just have to be some memory and resource leaks in there; and there's only 16mb of heap on the Android and its apparently surprisingly easy to leak in an Android app.
I've been looking around and so far have only been able to dig up info on 'hprof' and 'traceview' and neither gets a lot of favorable reviews.
What tools or methods have you come across or developed and care to share maybe in an OS project?
HTC Incredible :: Engadget Article - Droid Incredible Saves Browser Screenshots To Internal Memory
May 19, 2010This folder includes screen shots that are used for Internet Browser bookmarks. It also includes screen shots of web pages that I did not choose to bookmark. When I clear cache while in "Internet" in "Manage Applications" it does not remove these jpg files that are not being used for bookmarks. When I clear everything while in Internet app (in settings) it does not remove these jpg files either. It also does not remove them from within the HistoryEraser app. The only way I can remove the jpg files is with Astro or when connected to PC. I have to go through them and erase jpgs that I do not want there.
There were 72 jpg files in that directory and they go all the way back to when I got phone (on 4/29). I have only added 5 bookmarks myself during that time. They do not take up a lot of space but I just don't want them there.

Dec 23, 2009I am using kind of results search engine, problem is to remember the searching criteria i made singleton static class which keeps only one instance.In my application there are lots of class level private variables, lots of public static variables, a big util class which contains only static final methods.problem is my application get crash any time any where any spot and interesting thing is crash code always surrounded by try{} catch(Throwable e){} block but never catch, i think it may be memory full issue. I want to discuss one sample case, on the result page i also display result related image, i download image from web and using drawable i place image in the imageview, i created static hashmap to reuse images, some time after downlaod 5 images application crash some times click on a result get user to new detail screen get crash and all code surrounded by try catch block, i am new to mobile program this thing has become night mare to me.

View 1 Replies View RelatedAndroid :: Rebranding Wordpress App For Self Hosted Blog
Nov 15, 2010I just downloaded the source of wordpress app. I am on the process of rebranding the wordpress app (icons & labels) for my self hosted site. I was wondering, if there is a process / configuration option to remove the wordpress links & wordpress blogging options from my app. It doesn't make sense for the user to download my app from market place & go to wordpress site with it.I want the users be able to use both the default wordpress app & my self hosted app. However, for that, I think I need to change the package name in the android manifest and thus refactor all the old package names of all the java class. But then I will loose the ability to sync & get update of the latest build of the wordpress app.
Is there a way I can install the same code with the same package (as a different application) without conflicting with the wordpress app?Can anyone point me to the direction where I can find more details on the application namespace / package name conflicts?

Sep 24, 2010The timing of this week's blog post was perfect. It was exactly what I intended to do today. And the extra Ant step worked fine, and I can see Proguard obfuscate my files into bin/obf/obfuscated.jar (yes, I tweaked the file names and paths a little bit), the resulting App- release.apk does not include the obfuscated files. My first hint was my stack traces, but I confirmed it with dedexer. Has anyone else verified their .apk? How does the compile step know what .class files to use? (I'm hoping its not assuming some hard coded path.)
