I am using an image to set as the background for all my activities but it was causing a memory overflow issue and crash the app. Now I am unbinding my drawables on pause() and on Destroy() in my activity and now it shows blank screen on pressing back button. So how can I avoid this without using extra memory.protected void onPause(){super.onPause();unbindDrawables(findViewById(R.id.login_root)); }protected void onDestroy() {unbindDrawables(findViewById(R.id.login_root));super.onDestroy();}privat

I need 6 large images in my app. And I don’t need the quality and alpha channel provided by PNG. Is there a way to embed JPEG files into the raw resource and unfold them into SD card at first launch of the program? It will save me 3-4 MB in my APK. Thanks!

I want to display a random image from the bunch of images i have stored in res/drawable.The only technique that I know is to access a particular image if you know its resource id. Is there a way to access the images by using the filenames or something else (which can be constructed at runtime)?I want to randomly select an image at runtime. Any suggestions/ideas appreciated :)Thanks Chinmay

I want to display a large number of images(say 500).i am currently displaying them in a scrollable grid layout by lazyloading images(very similar to fedor’s lazylist). but i am having issues while scrolling the grid. when i scroll the grid, the views get refreshed and the actual images are reloaded. so, even the images that were displayed earlier are refetched from SD card. this causes a very slow UI. is there any solutions for this.(i.e is there a way to tell the grid view not to refesh views o

I’m saving an image from the device’s camera to a directory on the SD card (ex: /sdcard/appName/image.jpg), then I save the path into a database. My problem is that I can’t seem to load the images into a ListView with a cursor adapter.I tried the following code, where helper.getImg(); is a method from my database helper that returns a String (the file path), but it is not working.icon=(ImageView)row.findViewById(R.id.icon_pura); String imgPath=helper.getImg(c); Bitmap myBitmap=BitmapFactory.deco

I am setting a background Image in my first activity which fits the complete screen in XML code only. From the first activity user navigates to another activity which does something from an image selected by a user. Now, my point is since the app loads an image for the user , is it feasible to remove the background image from first activity. And are there chances of app getting crashed if I don’t remove the background image while migrating to the second activity.

My app needs to list texts and images for one particular activity. Each row of the list has 2 columns – 1 for image and 1 for string.It works if the number of images is small (ten or less). When it exceeds 10 (sometime 15), the app will crash. How can make this work for more than ten images?Below are the codes for listing the texts and images. The first 2 lines retrieve the data from strings.xml. Thanks.pic=res.obtainTypedArray(R.array.site_pic);arr_site = getResources().getStringArray(R.array.
