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?

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.

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?

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:

The HTTPMultipartMode.BROWSER_COMPATIBLE bit is very important.
In my android application I an storing an image file in internal memory using below code-

Can anyone please help me to read this image file from internal display it in an activity?
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?
In my app I am drawing bus routes on top of a MapView. The routes have anywhere between a dozen and a few hundred GPS coordinates that describe the route that the bus takes. The problem I'm having is that once I draw out all these lines panning/zooming the MapView is incredibly slow (even clicking the 'Back' button takes a minute to happen). I'm not sure how relevant it is, but I put in some debug code then checked the logcat output and the MapView is repeatedly calling the draw() method of the Overlay whether anything has changed or not. This is happening several times a second and is causing a massive amount of garbage collection to happen (2-3 MB every second).

My application requires that when a snapshot is taken it must store in memory and next time when I restart the phone I must get a thumbnail of that photo in list of photos and the full scale photo when I click on it.There are 2 ways I know.
1. Store images directly. Concern here is every time it has to hit directory to get image which takes some time.
2. Store all images in single xml. Concern here is XML will be too big and takes time to parse.

Currently I'm using a HashMap to map the strings to int and the int values need to be frequently accessed. I'm looking for a better way to do this if possible with minimal object creation, and preferable being able to store the values as primitive ints without wrapping them with the Integer class. (Basically, the reverse of the SparseArray's int->object mapping.)

I currently have a Service in Android that is a sample VOIP client so it listens out for SIP messages and if it recieves one it starts up an Activity screen with UI components. Then the following SIP messages determine what the Activity is to display on the screen.
For example if its an incoming call it will display Answer or Reject or an outgoing call it will show a dialling screen. At the minute I use Intents to let the Activity know what state it should display. An example is as follows:
Intent i = new Intent();
i.setAction(SIPEngine.SIP_TRYING_INTENT);
i.putExtra("com.net.INCOMING", true);
sendBroadcast(i);
Intent x = new Intent();
x.setAction(CallManager.SIP_INCOMING_CALL_INTENT);
sendBroadcast(x);
Log.d("INTENT SENT", "INTENT SENT INCOMING CALL AFTER PROCESSINVITE");
So the activity will have a broadcast reciever registered for these intents and will switch its state according to the last intent it received...............
