Numeri da capogiro per android

Ottocentocinquantamila nuovi dispositivi Android attivati ogni giorno: 850.000, pari a una media tranquillamente sopra i 25 milioni di apparecchi al mese, 300 milioni di device totali dal lancio. Cifre impressionanti che Andy Rubin, colui che per Google regola l'esistenza di Android, snocciola al Mobile World Congress di Barcelona. E sono pure cifre parziali, che non tengono conto di tutti quei milioni di apparati come Set-Top-Box o come il Kindle Fire che funzionano grazie a un fork dell'OS di BigG ma che non sono ufficialmente androidi. C'è solo un piccolo neo nei numeri di Rubin: i tablet non vanno come dovrebbero.
450mila applicazioni in circolazione (rispetto a 1 anno fa, sempre a Barcelona, sono triplicate), ogni mese oltre 1 miliardo di download dal Marketplace....

Android development : realtime scrolling chart using apache CircularFifoBuffer

Scrolling chart, code fragment written using the apache commons collection CircularFifoBuffer implementation.

Each refresh redraws the whole screen, giving the illusion of a scrolling chart without having to translate the canvas.

  import org.apache.commons.collections15.buffer.CircularFifoBuffer;
  .....
    private CircularFifoBuffer<Sample> mLocalBuffer;
    
    protected Runnable serviceConsumer = new Runnable() {

        @Override
        public void run() {
            if (!isStarted)
                return;
            synchronized (mLocalBuffer) {
                // se ha raccolto almeno un valore
                if (mService != null && mService.currentSample > 0 && !isScrolled) {
                    mScrollOffset = mService.currentSample;
                    Sample sample = mService.getSampleValue(mScrollOffset);
                    mLocalBuffer.add(sample);
                    drawSamples();
                    mReqNum++;
                }
            }
            handler.postDelayed(this, mUpdateSpeed);
        }
    };    
    .....
    
    protected void drawSamples() {
        Canvas c = new Canvas(mBitmap);
        c.drawColor(Color.BLACK);

        drawAxis();

        Paint paint = new Paint();
        if (isScrolled)
            paint.setColor(Color.GRAY);
        else
            paint.setColor(Color.GREEN);
        int lastX = 0;
        synchronized (mLocalBuffer) {
            for (Sample sample : mLocalBuffer) {
                float newY = mRect.centerY() + mScaleY
                        * (sample.values[SensorManager.DATA_Z] - SensorManager.STANDARD_GRAVITY);
                int newX = (lastX + mSpeed);
                c.drawLine(lastX, (lastX == 0 ? newY : mLastY), newX, newY, paint);
                mLastY = newY;
                lastX = newX;
            }
        }
        invalidate();
    }

    protected void drawAxis() {
        Paint paint = new Paint();
        paint.setColor(Color.WHITE);
        Canvas c = new Canvas(mBitmap);
        c.drawLine(mRectF.left, mRectF.centerY(), mRectF.right, mRectF.centerY(), paint);
        c.drawLine(mRectF.centerX(), mRectF.top, mRectF.centerX(), mRectF.bottom, paint);

Samsung Galaxy Nexus review | from TechRadar's expert reviews of Mobile phones

Samsung Galaxy Nexus review | from TechRadar's expert reviews of Mobile phones: "The Samsung Galaxy Nexus is the world's first phone to run Android 4.0 (Ice Cream Sandwich) and comes with a plethora of top end tech, including a huge but still massively high resolution screen.

There are some gadgets in geek-world that are announced and we just cannot wait to touch. Nokia's N95, the original iPhone, the T-Mobile G1 and Palm's first Pre. And the Galaxy Nexus fits firmly in that category.".....
