NineOldAndroids, Android library for using the Honeycomb animation API on old versions

In the post "Apply animations on layout changes using LayoutTransition" apply animation for deveice with API level 11 or higher. To apply Android 3.0 animation API on old devices, NineOldAndroids is an alternative.

remark: NineOldAndroids doesn't have LayoutTransition currently

NineOldAndroids is a Android library for using the Honeycomb (Android 3.0) animation API on all versions of the platform back to 1.0!

Animation prior to Honeycomb was very limited in what it could accomplish so in Android 3.x a new API was written. With only a change in imports, we are able to use a large subset of the new-style animation with exactly the same API.

This library also includes support for animating rotation, translation, alpha, and scale on platforms prior to Honeycomb!

Detect touch event in Processing for Android

Last exercise demonstrate the basic "Hello World of Processing for Android". This exercise show to to detect touch event, by implement surfaceTouchEvent() method.

import android.view.MotionEvent;

boolean showEvent = false;
int evAction;
int evX, evY;

void setup()
{
  size(displayWidth, displayHeight);
  background(0);
  
  stroke(255);
  strokeWeight(3);
}

void draw()
{
  if(showEvent){
    text("Action: " + str(evAction), 10, 50);
    ellipse(evX, evY, 10, 10);
    
    showEvent = false;
  }
}

public boolean surfaceTouchEvent(MotionEvent event)
{
  evAction = event.getAction();
  evX = mouseX;
  evY = mouseY;
  showEvent = true;
  
  return super.surfaceTouchEvent(event);
}

Hello World of Processing for Android

With Download and install Processing software and Setup Processing for Android development, we can noe prepare our first Hello World using Processing for Android.

- Start Processing and switch to Android Mode, by selection on the top-right pull-down box.

Enter the code:

void setup()
{
  size(displayWidth, displayHeight);
  background(0);
}

void draw()
{
  fill(204, 102, 0);
  rect(30, 20, 55, 55);
  text("hello Android + Processing", 100, 100);
}

With Android device connected, you can save and Run on Device under Sketch menu selection.

Setup Processing for Android development

Processing for Android project is aim to make it foolishly easy to create Android apps using the Processing API.

To setup Processing development tool for Android development, you have to install Android Developer Tools (ADT) in your system in advance.

Also you have to configure your Android SDK Manager to install Android 2.3.3 (API 10) - in Eclipse for Android Developer Tools, select Window -> Android SDK Manager:

otherwise you will have error of Unable to resolve project target 'android-10' when compile your Processing sketch.

- Download and install Processing software

Setup Processing for Android development:

Start Processing software:
- in Ubuntu, open Terminal, switch to your installed directory of Processing, type the command:
$./processing

- Select Add Mode in the Top-Right pull-down box.

- Select Android Mode, and click Install.

- You will be asked to select Android SDK installed location, click Yes.
