1. You can let camera return bitmap data, then you handle the data by
yourself. There is no file saved this way.
2. If you let camera save the image to file in a specified directory(through
provider), making a empty file named .nomedia in that directory can prevent
mediascanner from scanning it. This way this image will not appear in
gallery.
See the code below in Camera:
if (mSaveUri != null) {
OutputStream outputStream = null;
try {
outputStream =
mContentResolver.openOutputStream(mSaveUri);
outputStream.write(data);
outputStream.close();
setResult(RESULT_OK);
finish();
} catch (IOException ex) {
// ignore exception
} finally {
Util.closeSilently(outputStream);
}
} else {
Bitmap bitmap = createCaptureBitmap(data);
setResult(RESULT_OK,
new Intent("inline-data").putExtra("data", bitmap));
finish();
}
