Android : Need To Change - Old Image Is Staying In Memory
Oct 30, 2009
I'm getting some reports from the remote stack trace plug-in, with this error (see below)
What I'm doing, is findViewById(R.id.instructionsBack).setBackgroundResource (R.drawable.instructions1);
And then when I need to change the image, findViewById(R.id.instructionsBack).setBackgroundResource (R.drawable.instructions2);
From the error, I'm guessing that the old image is staying in the memory and preventing the new one from loading?
What's the correct way to do this kind of thing? Code...

My application is designed to support both portrait and landscape orientations. Using my HTC IO device, it survives 12 orientation changes before throwing an out of memory exception while inflating my activity.When I follow the recommended procedure of using DDMS to first force a GC and then write a heap dump, and then load it into the Eclipse Memory Analyzer, there is only one retained instance of my application, as there should be. None of the other retained objects are obvious offenders. Just for yuks, I reran the test, and did everything the same way except I didn't force a GC. In this case I see 13 instances of my application, which is more consistent with throwing an OOM exception. Is this telling me something useful? If forcing a GC with DDMS reclaims the memory used by now-defunct instances of my activity, I would have thought the VM would have garbage collected some, if not all of these defunct activities automatically. Do I need to request GC at the very beginning of my activity lifecycle to make sure?

I have a scroll view with lots of image buttons. I want to change the image for an image button when it's pressed. The thing is that I want the image to remain until another image button is pressed. That's why I couldn't use a selector. What is the best practice to achieve his?

I have some headache with an error about the system going out of memory. When I run the game fo first time there's no problem, but when i quit - with finish();- and then start the app again, it gives me an error.
The LogCat error says:
VM won't let us allocate 5529600 bytes ....
Caused by: android.view.InflateException: Binary XML file line #14:
Error inflating class java.lang.reflect.Constructor ....
Caused by: java.lang.reflect.InvocationTargetException ....
Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget.
it's strange because if I finish the activity and start it again without exiting the app then it's everything OK....but when i finish the app and push the button to load that activity... it crashes with this error and come back to the main menu...

I am trying to store an image in phone memory /data/data/com.myapp/ files/here.jpeg but I keep getting an exception. If I try to store the image using the normal 'FileOutputStream' it works fine. Can anyone point out what am I doing wrong? I want to store an image in my phone memory app folder so that when user is setting wallpaper the image can be listed in 'gallery.I do not want to store the image on sd card.

I am trying to reduce the size of images retrieved form the camera (so ~5-8 mega pixels) down to one a a few smaller sizes (the largest being 1024x768).It looks like the OOM happens during the createBitmap. Is there a more memory efficient way to do this? Perhaps something that doesn't require me to load the entire original into memory?

Is it possible to boot the phone (ADP1) from a compiled android image stored on the memory card without affecting the contents of the image flashed on the phone?
I would like to do this so I can work with development images, but I didn't want to mess with the factory image.

I have a list that shows items containing text and image. I have to download the images from the remote server and show as list item. things are working fine. The real problem is my list could have around 100 list items and each item has image downloaded from remote server. It is giving me OutofMemory error when I fetch around 70-80 elements. Could anyone tell me the best way to manage this situation?

This is the sequence part of this question: http://stackoverflow.com/questions/3674441/combining-2-images-overlayed
so the problem is: if the image size is too big - it'll got an exception (out of memory exception)
what i want is, to handle even if the handset got the lower spec hardware, it doesn't go to that exception (but it'll take a longer time to process the image) is it possible to do that?
The code snippet is like this:
CODE:......
And that block of code is inside the async task.

As part of my Android app, I'd like to upload bitmaps to be remotely stored. I have simple HTTP GET and POST communication working perfectly, but documentation on how to do a multipart POST seems to be as rare as unicorns.
Furthermore, I'd like to transmit the image directly from memory, instead of working with a file. In the example code below, I'm getting a byte array from a file to be used later on with HttpClient and MultipartEntity.
CODE:..............
This all seems fairly clear to me, except that I can't for the life of me find out where to get this ByteArrayPartSource. I have linked to the httpclient and httpmime JAR files, but no dice. I hear that the package structure changed drastically between HttpClient 3.x and 4.x.
Is anyone using this ByteArrayPartSource in Android, and how did they import it?
After digging around in the documentation and scouring the Internet, I came up with something that fit my needs. To make a multipart request such as a form POST, the following code did the trick for me:
CODE:.....
The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important.

What I'm trying to do is this: I want my application to download an image from the Internet and save it to the phone's internal memory in a location that is private to the application. If there is no image available for the list item (i.e. it can't be found on the Internet), I want a default placeholder image to display. This is the image that I have defined in my list_item_row.xml file as the default.
In my ListActivity file, I am calling an instance of a CustomCursorAdapter class I have written. It is in CustomCursorAdapter where I am iterating through all the list items and defining what content needs to be mapped to the views, including the image file by trying to read it from internal memory.
I've seen several questions on this subject, but the examples either are specific to external phone memory (e.g. SDCard), involve saving strings instead of images, or involve using Bitmap.CompressFormat to reduce the resolution of the file (which is unnecessary in my case, as these images will be small thumbnails of already-small resolution). Trying to piece together code from each example has been difficult, hence my asking about my specific example.
At the moment, I believe I've written valid code, but no image is displaying for my list items, including the default placeholder image. I don't know if the problem is being caused by invalid download/save code, or invalid read code - it doesn't help that I don't know how to check internal memory to see if the image exists.Anyways, here's my code...

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...
I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?

I am currently considering to develop an application for processing of images captured by the camera of mobile phones using the Android OS. Before I make the decision to go forth, I have done some research and found out there are some complaints regarding the limits of the memory allocated by the Dalvik VM, which seem to be limiting to applications that require manipulation and processing of images. Which limits should i have in mind if i would have to process for example 3 photos taken with the camera, in my process, applying filters, transforms and other types of mathematical operations?I would like to know if it is possible to change the default value of
memory allocated by the Dalvik VM for each application (this default is of 16 MB), in any way, using the Android 1.6 OS. Has anybody looked into this that can help me out please? I have also read in the Android 2.1 compatibility definition document
(available here: http://static.googleusercontent.com/external_content/untrusted_dlcp/source.android.com/pt-PT//compatibility/android-2.1-cdd.pdf )that it is possible to change the allocation of memory by the Dalvik VM from 16 MB to 24 MB or even a bigger amount if it is necessary, but t is not mentioned anywhere how this can be done. If someone has looked into those issues before.

the last 2 days I've tried to charge my phone, it connects for about 2 seconds, then disconnects. i have to move the cable around, almost bending it downward, for it to register a charge. its starting to get really annoying because i have to make sure its charging for a little bit and sometimes have to prop it up so the cable is bent for it to charge before i can walk away. I just want to check on this forum before i take it to the sprint store or best buy where i got it.

I read the other posts about WiFi but mine seems a little different. This just started happening a few days ago. I understand that when the phone goes to sleep it shuts off it's WiFi thats fine although I'd rather it not but eh whatcha gonna do about it. The problem I have is that after it wakes back up it says that it's scanning for networks. I have a lot of WiFi networks in my neighborhood and none of them show up. The work around I've found for this for the time being is to shut the WiFi off and then turn it back on. When I do this it connects back to my WiFi and life goes on.

My Girlfriend picked up a tab sometime ago last year for convenience at school and light internet usage but as of recently it has developed a problem.
The battery drains very fast, within like 5 minutes after being unplugged from the charger. While on the charger it will reach 100% and stay there but as soon as its unplugged it starts dropping drastically. The model is a Maxwest Tab - 9100.

I am working on changing the image being shown when I have my ImageView Clicked. I am trying to use a similar code that I used for accomplishing this with a TextView but I can't seem to find the right terms to get it to work. Here is my current code:
electronconfiguration.setOnClickListener(new View.OnClickListener() {
public void onClick(View drawable) { if (drawable.equals(R.drawable.element_el))
electronconfiguration.setImageDrawable(R.drawable.aluminum_el);
else if (drawable.equals(R.drawable.aluminum_el))
electronconfiguration.setImageDrawable(R.drawable.element_el);
} } );
