Hi all.
I'm invoking the MediaStore.ACTION_IMAGE_CAPTURE intent with the MediaStore.EXTRA_OUTPUT extra so that it does save the image to that file.
On the onActivityResult I can check that the image is being saved in the intended file, which is correct. The weird thing is that anyhow, the image is also saved in a file named something like "/sdcard/Pictures/Camera/1298041488657.jpg" (epoch time in which the image was taken).
I've checked the Camera app source (froyo-release branch) and I'm almost sure that the code path is correct and wouldn't have to save the image, but I'm a noob and I'm not completly sure. AFAIK, the image saving process starts with this callback (comments are mine):
private final class JpegPictureCallback implements PictureCallback {
...
public void onPictureTaken(...){
...
// This is where the image is passed back to the invoking activity.
mImageCapture.storeImage(jpegData, camera, mLocation);
...
public void storeImage(final byte[] data,
android.hardware.Camera camera, Location loc) {
if (!mIsImageCaptureIntent) { // Am i an intent?
int degree = storeImage(data, loc); // THIS SHOULD NOT
BE CALLED WITHIN THE CAPTURE INTENT!!
.......
// An finally:
private int storeImage(byte[] data, Location loc) {
try {
long dateTaken = System.currentTimeMillis();
String title = createName(dateTaken);
String filename = title + ".jpg"; // Eureka,
timestamp filename!
...
So, I'm receiving the correct data, but it's also being saved in the "storeImage(data, loc);" method call, which should not be called...
It'd not be a problem if I could get the newly created filename from the intent result data, but I can't. When I found this out, I found about 20 image files from my tests that I didn't know were on my sdcard :)
I'm getting this behavior both with my Nexus One with Froyo and my Huawei U8110 with Eclair.
Could please anyone enlight me?
Thanks a lot.
