  • 0

ok so im trying capture the webview on button click, of the web page that is being displayed on my webview activity and save it to the sd card.

i have in my manifest the right permission to write external storage and all webview features are working just great, just when i attempt to capture the image.

 public void onClick(View v) {
    switch(v.getId()) {

            case R.id.button1:
                WebViewClientDemoActivity.web.goBack(); 
                break;

        case R.id.button2:
                WebViewClientDemoActivity.web.goForward();
                break;

            case R.id.button3:
                WebViewClientDemoActivity.web.capturePicture();
                //Capture Picture
            Picture picture = WebViewClientDemoActivity.web.capturePicture();
            //Create a new canvas
            Canvas mCanvas = new Canvas();
            //Draw the Picture into the Canvas
            picture.draw(mCanvas);
            //Create a Bitmap
            Bitmap sreenshot = Bitmap.createBitmap(picture.getWidth(),
            picture.getHeight(),Config.ARGB_8888);
            //copy the content fron Canvas to Bitmap
            //mCanvas.drawBitmap(mBitmapScreenshot, 0, 0, null);
            mCanvas.drawBitmap(sreenshot, 0, 0, null);
            //Save the Bitmap to local filesystem
            if(sreenshot != null) {
                   ByteArrayOutputStream mByteArrayOpStream = new
            ByteArrayOutputStream();
                    sreenshot.compress(Bitmap.CompressFormat.JPEG, 90,
            mByteArrayOpStream);

                try {
                    File folder = new File(Environment.getExternalStorageDirectory().toString()+"/Enlighten/Images");
                    folder.mkdirs();
                    // create a File object for the parent directory
                    File outputFile = new File(folder, "enlighten.jpg");
                    // now attach the OutputStream to the file object, instead of a String representation
                    FileOutputStream fos = new FileOutputStream(outputFile);
                    fos.write(mByteArrayOpStream.toByteArray());
                    fos.close();
                    Toast.makeText(WebViewClientDemoActivity.this, "File Created", Toast.LENGTH_SHORT).show();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                    Toast.makeText(WebViewClientDemoActivity.this, "File Not Found", Toast.LENGTH_SHORT).show();
                } catch (IOException e) {
                    e.printStackTrace();
                }

Im getting this error message. (UPDATED)

    The openFileOutput() expects just the file name, without path separators, because it assumes that the file will be created in the app’s private data area (if my memory doesn’t cheat me then it should be /data/data/[your app package name]/files/).

    To create a file on sdcard you can use FileOutputStream directly, see here for an example.

    And another advice is that don’t use hardcoded path like /mnt/sdcard because the absolute path of sdcard may vary on different devices, instead you should use Environment.getExternalStorageDirectory()
