So kind of a little kink in my bitmap save... Any clues? here's the code...

Code: Select all

            case R.id.saveBtn:
                final Activity currentActivity  = this;
                Handler saveHandler = new Handler(){
                    @Override
                    public void handleMessage(Message msg) {
                        final AlertDialog alertDialog = new AlertDialog.Builder(currentActivity).create();
                        alertDialog.setTitle("Saved 1");
                        alertDialog.setMessage("Your drawing had been saved.");
                        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                                return;
                            }
                        });
                        alertDialog.show();
                    }
                } ;
               new ExportBitmapToFile(this,saveHandler, drawingSurface.getBitmap()).execute();
            break;

I hope that's all the code you need otherwise it could get hairy... any clues are much appreciated.

What that is stand for?
Please come with some detailed reply in order to get the exact answer.

Do you not see the picture? The picture is what i'm talking about when i export the drawing canvas to an image file saved on my sdcard. It comes out very distorted. I am not sure what is wrong with it.

i have the same problem and still no solution. i think when we draw on canvas . our running thread draw another canvas over the canvas on which we draw and when we save it looks like that some part of bitmap is missing....... realy need some solution.....please

i found the solution ............................. in ur surface view u have a method _run
to run the background thread to lock and unlock the canvas. you have an (if (mBitmap ==null)
{
create bitmap;
})
condition there
you have to remove this condition which will allow the program to create new bitmap every time this problem will be solved
