Problem Playing an Audio File/Clip

I'm attempting to work with Android's SoundPool() in Processing. The two separate files below are in the same Processing project. I can either use the Processing IDE itself or ant to compile and install them to my phone but soundPool.play() doesn't seem to work properly either way - no sounds are played and it returns a zero, which indicates a failure. I followed this example: http://www.droidnova.com/creating-sound-effects-in-android-part-1,570.html. I've played with MediaPlayer() as well but still no sound is played.

I've searched but couldn't find a solution for soundPool.play() returning a zero. Has anyone had any success with either soundPool() or MediaPlayer() in Processing for Android?

I have yet to try the Pd libraries for Android but that is next on the list.

Much thanks,

Gary

LetterBaby for Android (Updated)

I've updated my "LetterBaby" Android app including limited Android text-to-speech sounds (US English) and many wintery images. I also released a "full" version where each of the 125 pictures plays TTS sounds. Here are the appbrain listings. These were made with Processing. Please give them a try!! I would love to hear your feedback either here or comments in the dev log.

Here is the description:

LetterBaby is a picture alphabet game for young children ranging from toddler to preschool - it helps teach association of letters, words, pictures & sound!

*Swipe screen, use keyboard or DPAD
*Home exits, use supervision
*Try free version before buying
*Normal and large screens supported
*No ads

Recent changes:
v0.1.9
*Swipe forward/backward to get to next/previous letter
*Use keyboard to jump to a letter
*Use DPAD to advance to next letter
*Clicking an image will run Android's US English text-to-speech

-------------------------------------------------------------------------------------------------

I originally posted this in the Processing > Android Forum but I just noticed there is an Exhibition forum, so I thought I should copy it here as well. Thanks in advance to any Android users willing to try it. Enjoy!

-------------------------------------------------------------------------------------------------

I'm starting this discussion on an Android app I built with Processing and recently added to the Android Market. I submitted a free "beta" of an alphabet picture game for kids called LetterBaby. It currently has ~70 cartoon images designed for toddlers/young kids to scroll through (or click through with a DPAD/optical button), it also processes input from the keyboard. Here is the listing on appbrain. I'd like to eventually add more pictures, different play modes, sounds, etc.

I originally designed it for the PC so my toddler could learn to associate letters, words and pictures, and because I wanted to promote using the keyboard/PC as a sort of toy. I've focused solely on developing it for Android ever since learning it was possible to run Processing apps on Android.

I would love any criticism or feedback from anyone willing to try it. Feel free to share pros/cons you observe while you and/or your child are using it. So far I'm considering adding a delay so the user can really learn the images (the pictures may not be on-screen long enough when clicking rapidly with the DPAD). I've confirmed it installs and runs on the Motorola Droid, HTC Incredible/Desire, N1 and Samsung Captivate; it does not (may not) run on the Samsung Moment.

If anyone has any insight as to why it may not work for the Samsung Moment, that would be helpful as well.

Another black screen when exiting app via Home

I recently added a separate thread to my program - images seem to load (much) quicker now as compared to when they were loaded in the setup routine. However, this seems to cause the black screen when I start the app again. The same phenomenon was described here but was "fixed" when using A3D in the size() command. The issue has cropped up again now that I have started to use a separate thread.
The code is basically set up like this:
1. void setup(){
2. ...
3. imageThread = new imageThread(); // loads images faster
4. imageThread.start();
5. }
6. void draw(){
7. ...
8. }
9. private class imageThread extends Thread{
10. imageThread();
11. public void run() {
12. // Load images here.
13. }
14. }
Note: Using System.Exit(0) seemed to fix the black screen problem but that may have it's own issues...

How to Properly Quit App when Home Button is Pressed (can't detect or override Home button)

[18 Replies]

14-Sep-2010 06:48 PM
Forum: Android Processing

Using the Home button to exit my app does not work. After pressing home and restarting, the app has a blacked-out screen until I force close it (I believe the app is "running" because I see some printed debug text in the processing output space). Properly detecting the Home button and performing the appropriate quit sequence would be preferred but currently I'm trying to override the Home button. Quiting and restarting works perfectly when using the Back button.

The following code is taken from the android processing wiki. Pressing home returns the user to the home screen rather than be overridden as desired. Is it that we cannot override the Home button (without using a more complicated method)? Any suggestions as to what I'm missing? On the other hand, this code works fine when used with KeyEvent.KEYCODE_BACK and onBackPressed().


 void keyPressed() {

      // doing other things here, and then:

      if (key == CODED && keyCode == KeyEvent.KEYCODE_HOME)

      { // override the home key here }

I added the following to my code:

                         
                          public void onHomePressed() {
                           // Do nothing... 
                          }

Thanks,
Gary

EDIT 1: I'm not certain I can use this to my advantage, but I found that the Home button calls onUserLeaveHint() however the Back button does not. onResume and onPostResume run when I restart whether I exited via Back or Home

EDIT 2: I recently noticed that print() statements in the setup() routine are not working when I restart the app after exiting via the Home button but they do execute when I exit via the Back button. print() statements in the draw() routine work either way.

mouseX/mouseY and surfaceTouchEvent

[3 Replies]

The Processing for Android wiki states that I'll need super.surfaceTouchEvent() to get proper mouseX/mouseY variables.Currently, my code is reading mouseX/mouseY at the start of the mousePressed(), mouseDragged() and mouseReleased() functions. So do I essentially call super.surfaceTouchEvent in each of these? I mostly just store mouseX/mouseY until mouseReleased occurs. Here's my declaration of surfaceTouchEvent():
1. public boolean surfaceTouchEvent(MotionEvent event) {
2. float xoff = mouseX;
3. float yoff = mouseY;
5. return super.surfaceTouchEvent(event);
6. }
Here I'm storing mouseX/mouseY whenever surfaceTouchEvent is called. Is this all I need to do here or should the processing for Pressed/Dragged/Released be moved here? Any hints on making use of super.surfaceTouchEvent() would be appreciated.

EDIT: Note that the touch/cursor position is working as is, without using surfaceTouchEvent.

Much thanks,
Gary

Surface View

I've loaded a sketch onto my HTC incredible. I notice that the screen orientation flips when you turn the phone on its side. When I go from vertical to horizontal the Processing output window says:
SketchSurfaceView2D.surfaceChanged() 800 480

This also seems to re-start the app. Both the change in screen orientation and the re-start occur when I'm connected via USB (i.e. Sketch > Present) as well as running the app from the phone.

Is there a way to prevent this from happening?

Much thanks,
Gary
