How to create notifications, even when the app is closed.
Okay I am new to android app development! I have been using ketai lib. to creat my apps so far and everything went super smooth.
But now when I searched how to create notifications using processing, I found things getting complicated. I thought I will have an another lib. to perfrom notification action. But I was wrong.
Can some one help me with a code on how to handle notifications in android. (OR) Suggest me where to start learning https://developer.android.com/guide/topics/ui/notifiers/notifications.html#CreateNotification I started here, but was not able to understand a line.
Its okay if it would take a lot of time for me to read and understand, I am ready to go trough it. I would be happy, if someone could show me the code also!!

Notifications in Android Mode
Hi! I'd like to have notifications in my app, but I know that the way in which a processing sketch works on Android is a bit different; I've been able to include toast notifications (that we can see when the app is on the screen), using the Android constructors.
A piece of code for Toast Notifications:
// The Looper is necessary for displaying Toast Notifications
import android.os.Looper;
import android.widget.Toast;
class TOASTnotifications extends Thread {
// Text of the notification
String txt = t;
// Duration of the notification
int time = n;
public TOASTnotifications (String t, int n) {
txt= t;
time = n;
}
public void start() {
super.start();
}
//@Override
public void run() {
Looper.prepare();
Toast.makeText(this, txt, time).show();
Looper.loop();
}
}
But I'd like to see notifications in the android notification center, and then return to the app when I click on them.
Thanks in advance for any help

Android PShape and Draw Order
Hello
in my processing/android app I use P2D and a lot of PShapes. but the thing is that it seems to me impossible to draw anything other than a PShape UNDER those PShapes I made.
I need to draw lines (complicated/dynamic/cannot do with PShape) in the background but wherever in the code I draw my lines, there appear OVER the PShapes.
Any Idea on how to control this kind of z buzzer for 2D ?
cheers :)
(writing this after a good, long, research on google, forums for v1, 2 and 3 of processing, OpenProcessing etc...)

Hello people,
I'm sketching an app that pick colour from the camera and turn it into a sound frequency. On the computer I used minim to generate my tone, where I also need to tune the decay, and release and stuff. I now know that minim doesn't work on android because of the javasound part.
Any idea how I could still make sounds happen there ?

I'd like to have simple AlertDialog in my Processing-Android sketch
Hi,
I'd like to have simple AlertDialog window with OK confirm button in my processing sketch for Android target...
I've found example code here : http://forum.processing.org/one/topic/android-pop-up-windows#25080000001725349.html
but it doesn't work. It seems that fix is not that hard but is beyond my newbie knowledge in Android field... There is a hint how to solve this but I don't know how to use it (it's commented)...
My code :
//Import required classes import android.app.AlertDialog; import android.content.DialogInterface;
// Activity activity;
void setup() {
// activity=(Activity) this.context;
// activity.runOnUiThread(Runnable r) ;
//Create the AlertDialog
AlertDialog alertDialog = new AlertDialog.Builder(this).create();
//Set the title
alertDialog.setTitle("Alert");
//Set the message
alertDialog.setMessage("This is an AlertDialog!");
//Add the OK button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
//The OK button has been clicked
}});
//Display the AlertDialog
alertDialog.show();
}
void draw() {
}
I get this error :
FATAL EXCEPTION: Animation Thread java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() at android.os.Handler.(Handler.java:121) at android.app.Dialog.(Dialog.java:101) at android.app.AlertDialog.(AlertDialog.java:67) at android.app.AlertDialog$Builder.create(AlertDialog.java:800) at processing.test.popup_test.popup_test.setup(popup_test.java:35) at processing.core.PApplet.handleDraw(Unknown Source) at processing.core.PGraphicsAndroid2D.requestDraw(Unknown Source) at processing.core.PApplet.run(Unknown Source) at java.lang.Thread.run(Thread.java:1019)

Generating Audio in Android (by playing multiple short audio files concurrently)
Hi Everyone
I would like to generate sounds using Processing for Android. The way I would like to do that is by generating individual pulses and varying the timing between them (Shorter interval = higher pitch).
[I'm using this audio to generate haptic feedback - ultimately planning on running an experiment with it, that's why I need this type of low level control over the audio output - I'm essentially trying to recreate something that I have built in MAX/MSP a while ago]
I was hoping to prerecord an impulse and then play it say, every ~20 milliseconds. I just started tinkering with the cassette library for doing this (https://github.com/shlomihod/cassette) however, I am unable to play the same sound multiple times concurrently:
Lets say my audio file is 1 second long and I try to do this:
pulse = new SoundFile(this, "impulse.wav");
pulse.play();
delay(20);
pulse.play();
the second pulse does not play (because the first one is still playing)
I need to do this:
pulse = new SoundFile(this, "impulse.wav");
pulse1 = new SoundFile(this, "impulse.wav");
pulse.play();
delay(20);
pulse1.play();
now I hear both pulses.
Obviously loading the pulse thousends of times on program start is a clumsy way of doing this. Does anyone have any other suggestions on how to set this up? Please not that I need to be able to set the interval between two pulses individually for each interval.
Is this even feasible?
How would you approach this?
