Solution 1: I have a simple program that draws the preview of the Camera into a SurfaceView . What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView , in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class Superficie extends SurfaceView implements SurfaceHolder . Callback { SurfaceHolder mHolder ; public Camera camera ; Superficie ( Context context ) { super ( context ); mHolder = getHolder (); mHolder . addCallback ( this ); mHolder . setType ( SurfaceHolder . SURFACE_TYPE_PUSH_BUFFERS ); } public void surfaceCreated ( final SurfaceHolder holder ) { camera = Camera . open (); try { ...

The question does arise, why would you need USB drivers for your Android smartphone or tablet? And, if they’re so important, how come you haven’t had to install those for most of your devices? The answer to this can be multi-faceted. For one, it depends on which Windows version you’re using. In the later iterations of the operating system, Windows update can serve USB drivers for many Android devices from reputable OEMs (Original Equipment Manufacturers). Then, since most of these devices connect, by default, in USB (mass) storage mode, a generic driver can suffice. At still other times, you may have installed an accompanying PC suite or like for your handset, and that, in turn, would’ve set up the proper drivers, too. As I said, there can be various scenarios, each with its own explanation. However, things play out a little differently when you connect your Android device in USB debugging mode, an essential requirement for application development in Windows, and for m...
