Application crashing on using Bitmap in for loop

Question

for (int k = 0; k < file.length; k++) {
        Bitmap myBitmap= null;
        myBitmap = BitmapFactory.decodeFile(file[k].getAbsolutePath());
        bitMap.add(myBitmap);

}

My App is crashing when i am using this code for storing all image in bitmap Arraylist, For lesser number of image it works fine, but for more then 30 images it crashing.

If you look here

http://developer.android.com/reference/android/graphics/BitmapFactory.html#decodeFile%28java.lang.String%29,

you'll find out that decodeFile can return null. Therefore, you should check myBitmap before using it

You'll find this interesting as well:

Sounds like you are getting out of memory.. Not a NPE as someone mentioned in his answere. Use smaller images and scale them up when needed. Would be my first suggest without seeing logcat. Hope it helps.
