I am reading pdf using itext on android platform and i'm using the following code.but when i try to open large pdfs it gives out of memory error on first line i.e. reader = new PdfReader(fileName);.Also below is the satck trace generated when a large file is clicked.
reader = new PdfReader(fileName);
numberOfPages = reader.getNumberOfPages();
System.out.println("This document contains:" + numberOfPages);
extractor = new PdfTextExtractor(reader);

There is a related discussion about memory allocation in another thread here on SO:
Android memory allocation
Haven't tried it myself but it might be worthwhile to try the option
android:largeHeap="true"
in the manifest since its hitting the 16MB upper boundary.

I am creating Image apps which has over 4k images. I dont load images as required rather load when required however if user visits different parts of app which links to different images my app becomes slow and waits for GC to run which makes it bad user experience.
I saw logcat with following messages:

I tried to improve/optimize my code by doing following changes:
Everytime I load app I clear my cached images.
Implemented ViewHolder pattern for ListViews.
Used android:largeHeap="true" attribute in Manifest at Application tag level.
Made classes which are used frequently to do some operations singleton.
But still not able to achieve performance i need.
I used Universal Image Loader Library which has cache mechanism but still its runs GC.
How to avoid GC or what are other optimization techniques.
I have exit my app, but there is still a backgroud service is running. Whe the GC logs come a log. I will so you the logs beblow. You can see, about 3 logs per second. Is This phenomenon is normal ? My device's memory is enough, and the backgroud service is holding a WebSocket connection.

Is This phenomenon is normal ?
It depends what you mean by "normal".
If you mean normal for an application with those particular heap dimensions, that amount of heapspace used for long-lived objects, and that rate of allocation ... then the answer is "Yes, it is normal".
Basically, you are running your application with a heap that is (objectively) too small for the work that you are asking it to do. You have roughly 2Mb of free space, and you are allocating objects at roughly 6Gb per second. If you want to reduce the number of GC cycles, you need to do one or more of the following:
Increase the heap size. (I don't know if this is feasible for an Android app ...)
Reduce the "working set" of long-lived objects. Maybe you have a memory leak, lots of large images loaded, or an overly large in-memory cache of ... something.
Reduce the rate at which new objects are being allocated by your application.
The last two require you to track down the source of the memory usage / allocation, and change you code to mitigate the effects. There are tools (memory profilers) that can help with this, but the details will be specific to your application.
Here's how I'd interpret the GC log lines ... by example:
08-11 10:33:54.456 6821-6823/com.tong.iknow:ik_service_v1 E/dalvikvm﹕
GC_CONCURRENT freed 2020K, 18% free 10682K/12871K, paused 12ms+6ms, total 44ms
The "GC_CONCURRENT" collector is being used.
This GC collection cycle reclaimed 2020K bytes.
When the GC cycle completed, 18% of the heap is free, and 10682K out of a total usable heap size of 12871K is in use.
Normal thread activity was paused for two intervals of 12ms and 6ms respectively.
The elapsed time for the GC cycle was 44ms.
Note that the amount of heap freed isn't always exactly the same as the different between total and available ... because for much of the time that the GC is running there are normal threads allocating new objects.
I have 1700 markers with strings holding a description for each marker on the map. I am getting the out of memory error since I am holding so many strings for each markers "click for more info" next screen activity. How can I better hold this data and share it on marker click and not have this memory issue? I am pulling my data from an XML based file.

I am posting them on the map like so:
BitmapDescriptor icon = BitmapDescriptorFactory
.fromResource(R.drawable.snotel_marker);
int nsize = visibleMarkers.size();
for (int i = 0; i < nsize; i++) {
MapMarkers marks = new MapMarkers();
String title = visibleMarkers.valueAt(i).getTitle();
String desc = visibleMarkers.valueAt(i).getDesc();
Float latitude = visibleMarkers.valueAt(i).getLat();
Float longitude = visibleMarkers.valueAt(i).getLon();
m = map.addMarker(new MarkerOptions()
.position(new LatLng(latitude, longitude))
.title(title).icon(icon));
marks.setTitle(title);
marks.setDesc(desc);
m.setData(marks);
On Info Window Click the next activity is populated like so:
getSupportActionBar().setTitle(extras.getString("name"));
webview.loadDataWithBaseURL(null, extras.getString("description"),
"text/html", "utf-8", null);
The app runs fine on my GNex, but on my old Droid, it populates the map, then after clicking on 3 or 4 markers and moving the map around I get the out of memory error. Any other output I can share to try and figure this out?

in my simple app i am using 6 buttons and setting background with png.
Button btnGadgetmusic = (Button) findViewById(R.id.gadgetmusic);
btnGadgetmusic.setBackgroundResource(R.drawable.btnselectedsong);
minimum size of png is 13.5K and maximum size is 40K. When ever i try to run this app on emulator with version 2.3, i get "external allocation too large for this process" and interestningly if i run on honeycomb or on ICS then there is no problem.
So i am confused what should i do, should i ignore it, if not, do we have some better solution for that.
looking for your reply

The heap keeps growing and growing and I have no idea what I can do about it. I searched through the web and through stackoverflow, but there was no helpful answer for me.
I hope someone of you can find the error. I am very new to Android, so please appreciate.

First, your heap doesn't "keep growing". It is hovering between 12893K and 13054K, rising and falling, with one outlier peak at 13925K. Personally, I don't see anything in that log that would worry me.
Regarding your MAT output, if those are the three top culprits, none are surprising. The latter two say "I am writing an app for Android", as those are always there on any Android app. The first one indicates that Maps V2 has one rather pudgy object. Again, I see nothing in that output that would suggest a problem.
