Question

I’m trying to capture a photo with the camera and save it (to be previewed later) and it seems to work with the emulator but when I use it on my GalaxyS – it doesn’t save the file (I use RootExplorer to check) and there’s no preview.

What am I doing wrong?

Code for saving the file:

public void onPictureTaken(byte[] data, Camera camera) {
      FileOutputStream outStream = null;
      try {
        // Write to SD Card
        String filename = "captured_image.jpg";

        Log.d("@@--File name--@@", filename);
        outStream = openFileOutput(filename, Context.MODE_WORLD_READABLE); // <9>
        outStream.write(data);
        outStream.close();
        Log.d(TAG, "onPictureTaken - wrote bytes: " + data.length);
      } catch (FileNotFoundException e) { // <10>
        e.printStackTrace();
      } catch (IOException e) {
        e.printStackTrace();
      } finally {
      }
      Log.d(TAG, "onPictureTaken - jpeg");
    }

Code for displaying:

ImageView imagePrev = (ImageView) findViewById(R.id.image_capturedimagepreview_preview);


        Bitmap bmp = null;
        try {
            bmp = BitmapFactory.decodeStream(openFileInput("captured_image.jpg"));
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } 
        imagePrev.setImageBitmap(bmp);

Answer 1

i think i found the problem.
instead of outStream = openFileOutput(filename, Context.MODE_WORLD_READABLE); i should use outStream = getApplicationContext().openFileOutput(filename, Context.MODE_WORLD_READABLE);

but now i’m facing a new one – the file seems to be corrupted cause when i open it with the Android’s viewer it’s just black and its size is always 18474 bytes.

any ideas?
