Mainly the Window Leaked error raises the Illegal Argument Exception? how to rectify both og this.

Will 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?

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 RelatedI 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?

What could be some possible things that are causing the leak? I've tried many things. And I do have a unregisterCallback(..) call.

But I don't understand if it is ok to create an class that looks like this one:

View 4 Replies View RelatedI'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?
Any 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.
I'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?
I 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. Last thing, On emulator hardly application crash but when i try to test the application on device, i am using samsung glaxy android supported to test the application it goes smoth and suddenly it start getting crashed, and after crash android relaunch the activity that throws null pointer exception on every click and caught by try{}catch{} block i think after crashing android dealocate all objects only keep the UI objects thats why when after crash i auto launch the activity clicking causes null pointer exception.how can i stop relaunching crashed activity?

View 1 Replies View RelatedMy android app is getting an "Out of memory" error without a useful stack trace. It occurs after I have repeatedly re-invoked its main logic through a menu interaction, which leads me to believe that there's a memory leak somewhere.
I say that the stack trace isn't useful because it doesn't include references to any of my own code. There are no references to my own code in the logcat output, either.
I'm wondering if any of you can help me figure out where my memory leak might be occurring, given my stack trace and my logcat output.
Here's the stack trace: Code...
Could my error be related to the "Window already focused ..." warnings? If so, how can I find out what is causing these? I know that I could sprinkle my code with lots of calls to Log.v() in order to zero in on where my problem might be occurring, but I'm wondering if there is a better way to get more meaningful information about the cause of my memory leak.
Is it just me, or does it seem like it's been, what, a couple months since the last Froyo RC leak? Ok, maybe more like several days, but aren't you guys starting to jones hard for a newer 2.2 leak? When the first couple came out so quickly one after the other (along with the multiple new baseband versions) it seemed like it was going to be raining Froyo leaks (that sounds odd, doesn't it?) on an almost daily basis. I'm running well on BB Froyo v.2.0 plain vanilla, but looking forward to the next 2.2 RC to stumble out of Moto/Verizon's castle so we can continue the informal beta testing for them.
View 15 Replies View RelatedI have been messing with my eris. I held the power and send button and as usual it checked the leak file and asked if I wanted to update. At this time I noticed a list from one to four., one thing that was listed was bootloader and another was hboot My question would there be a way to get into the 2.1 leak file and some how switch the hboot and bootloader in it with the hboot and bootloader that is on the official ota file or some other jnoot or bootloader. Then convert it back to a zip file and reinstalling it like out was a v4 leak. Sorry if this was a stupid post but just trying to help leak users or devs brainstorm a little.
View 5 Replies View RelatedNow that it looks like the 2.2 SBF is online, how many people who are running leaks are going to upgrade to the 2.2 OTA that supposedly include an updated bootloader/kernel/radio? For those who did already, do you see any differences at all? Moto made some claims that the new one was better (i.e. that switching between wifi and 3g would be more seamless), but have people noticed differences? I guess I held out on upgrading to OTA because of the no SBF and the whole episode of the unlocked bootloader, but now should I consider upgrading? Would I lose any advantages of staying on the old boot loader?
View 7 Replies View RelatedI found this on Android Central (thanks to IzelTokatl) and someone there did verify it worked for OTA 2.1 phones. I tried it on my leak version 3 phone and I got the Hboot error again. I'm thinking this does not bode well for phones with the leak as once Verizon releases the upgrade for download from PCD or HTC we still won't be able to use it until the Hboot problem is fixed. The following instructions for doing the downgrade to 1.5 are cut and pasted from the Android Central forum and I edited them for PC's: Download the MR2 Upgrade Eris ROM from verizon partner: personal Communications Devices
1. Unzip the file
2. Plug your phone into your PC.
3. Navigate to folder ADR6200_MR2_Upgrade
4. Run .exe file in the folder (RUU_Desire_C_Verizon_WWE_1.17.605.1_release_signe d_with_driver.exe)
5. follow on screen instructions.
What is the basic difference between the PhoneWindow and MidWindow policies? I found that the emulator version takes the implementations of the PhoneWindow.When the MidWindow implementations will be used? Also, I found that PhoneWindow handles the call settings implementation and the same is not there in MidWindow? Please someone help me pointing out the differences between both the policies and under which circumstances which one will be used.
