Facing out of memory issue when shows large thumbnails in each row of listview.
Clearly you're doing this wrong. Android gives you an extremely limited memory space. You should show thumbnails in your listview and only load the full images into memory (from the sdcard) when they've been selected. Also remember to recycle() your Bitmaps if you're loading them manually.

I have created an app which displays photos in a gridview and I want to load the photos from internet as the user scrolls up (like the pinterest app and facebook app), how can I make this?
The website exports a list of images and the app must load that in background and display the images as the user scrolls up.

I am new to Android. I am trying to make gallery view just like turning pages in a book. So kindly give me some suggestions.
What you are looking for is called a page curl or flip animation. There are plenty of open source libraries to implement this. You can try any of these:
android-page-curl
Android-Flip
page-curl-harism
3d-flip
Good luck !

I am working with automation.I want to start DDMS through my program and take the heap dump of the application programmatically . That is,instead of the clicking on the heap dump button i want to take the dump through program.Is that possible? how?
Use Debug.dumpHprofData(String) to generate a heap dump.
Dump "hprof" data to the specified file. This may cause a GC.
No DDMS needed.
