Admittedly so short a ride that I may as well walk, I am being driven bazonkers by my rather simple (so far) app failing when trying to show the first Activity. It all displayed fine until I added some code to actually make it do something besides look pretty.Perhaps an Android guru will glean a reason from a slew of clues:1) The possibly pertinent errors in LogCat:01-29 19:57:58.168: W/ActivityThread(388): Application com.aXX3AndSpace.OnDemandAndAutomatic_Package is waiting for the debugger on

The problem I have is that Proguard keeps crashing my app on start and it’s hard to figure out what’s failing.I’m using the Android V4 support compatibility library and it seems to be blowing away that library as well as some other stuff.Does anyone has a proguard.cfg that works with a basic version of the v4 compat library for starters?Currently I’m using the stock proguard.cfg which doesn’t work

android memory-management android-imageview
You load in image in ImageView (android) , how is the memory allocated for it?And whether the memory allocated is in 1D array or 2D array? (like in terms of pixels maybe)And which is better BufferedImage or Bitmap for image handling?PS – It is not a duplicate of this.

android drag-and-drop imageview android-imageview ontouchlistener
SOLVEDSee the simple solution in the accepted answer I posted below.The Original ProblemSo I’ve created an onTouchListener for dragging Views. Images drag smoothly if I use getRawX() and getRawY(). The problem with that is the image will jump to the second pointer when you place a second pointer down then lift the first pointer.This onTouchListener attempts to fix that issue by keeping track of the pointerId. The problem with this onTouchListener is while dragging an ImageView, the ImageView jum

android android-layout android-imageview android-gallery
I have working sample of image gallery.Now if I have 10 images in gallery, few of them gets displayed initially, lets say 3 (based on image thumbnail dimensions), and rest of the images can be viewed by scrolling the gallery.I want to change this a bit. Based on image thumbnail dimensions, few images should be displayed initially and instead of scrolling, there should be previous and next buttons, on click of which images will shift left or right.Any help appreciated.
