When you click the list row, it launches a new activity. I have had to build my own tabs because of an issue with the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the SD card) the application returns from the activity back to

the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. The image preview on the list view is being done with the cursor and ListAdapter. This makes it pretty simple, but I am not sure how I can put a resized image (I.e. Smaller bit size not pixel as the src for the image button on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. Is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? This would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row with touch screen because of focus issue. (I can use roller ball.) I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice. As soon as I disabled the image on the list view it worked fine again. FYI: This is how I was doin

of memory error is very common error when you are developing for a application that deals with multiple images sets or large bitmaps or some Animation stuff. In this case we have to be very careful and efficient while handling the images or object allocation http://blogs.innovationm.com/android-out-of-memory-error-causes-solution-and-best-practices/ and deallocation. OOM error comes when the allocation crosses the heap limit or your process demand a https://www.quora.com/How-do-I-prevent-out-of-memory-exception-in-an-Android amount of memory that crosses the heap limit. In Android, every application runs in a Linux Process. Each Linux Process has a Virtual Machine (Dalvik Virtual Machine) running inside it. There is a limit on the memory a process can demand and it is different for different devices and also differs for phones and tablets. When some process demands a higher memory than its limit out of it causes a error i.e Out of memory error. Possible Reasons: There are number of reasons why we get a Out of memory errors. Some of those are: 1. You are doing some operation that continuously demands a lot of memory and at some point it goes beyond the max heap memory limit of a process. 2. You are leaking some memory i.e you didn't make the previous objects you allocated eligible for Garbage Collection (GC). This is called Memory leak. out of memory 3. You are dealing with large bitmaps and loading all of them at run time. You have to deal very carefully with large bitmaps by loading the size that you need not the whole bitmap at once and then do scaling. The biggest reason for Out of memory is a Memory leak. First lets see a memory leak examples: Examples: 1. We make an Activity and create a TextView with Activity context and set a sample text in to it. @Override protected void onCreate(Bundle state) { super.onCreate(state); TextView label = new TextView(this); label.setText("Leaks are bad"); setContentView(label); } 1234567 @Override protected void onCreate(Bundle state) { super.onCreate(state); TextView label = new TextView(this); label.setText("Leaks are bad"); setContentView(label); } This means that views have a reference to the entire Activity and therefore to anything your activity is holding onto; usually the entire View hierarchy and all its resources. Therefore, if you leak the Context (“leak” meaning you keep a reference to it thus preventing the GC from collecting it), you leak a lot of memory. Leaking an entire activity can be really easy if you are not careful. 2. When the screen orientation changes the system will, by default, destroy the current activity and create a new one while preserving its state. In doing so, Android will reload the Application’s UI from the resources. Now imagine you wrote an application with a large bitmap that you don’t want to load on every rotation. The easiest way to
