Title Body

I'm developing an application for taking screenshots in the device. In this application, we can draw anything on the screen. For this I am using Canvas, Paint and Path to do this. I'm using this code to take screenshots: public void saveScreenshot() { if (ensureSDCardAccess()) { Bitmap bitmap = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); onDraw(canvas); File file = new File(mScreenshotPath + "/" + System.currentTimeMillis() + ".jpg"); FileOutputStream fos; try { fos = new FileOutputStream(file); bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos); fos.close(); } catch (FileNotFoundException e) { Log.e("Panel", "FileNotFoundException", e); } catch (IOException e) { Log.e("Panel", "IOEception", e); } } } /** * Helper method to ensure that the given path exists. * TODO: check external storage state */ private boolean ensureSDCardAccess() { File file = new File(mScreenshotPath); if (file.exists()) { return true; } else if (file.mkdirs()) { return true; } return false; } However, when the following line is run: Bitmap bitmap = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_8888); my application closes with the following exception: 11-28 15:05:46.291: E/AndroidRuntime(8209): java.lang.IllegalArgumentException: width and height must be > 0 If I change the height and width, the screenshot is taken, but it's empty: Why is that happening? What am I doing wrong?
