This ought to be simple but I can't figure it out. I want to use the
Camera app to take a picture, then I want to view it in a picture
viewer such as Gallery. Since the camera in the emulator doesn't work
yet, I'm doing this on a Motorola Droid device. I do the following in
my application (captureImage is called from a button click):
public void captureImage(View view)
{
ContentValues values = new ContentValues();
values.put(Media.TITLE, "My demo image");
values.put(Media.DESCRIPTION, "Image Captured by Camera via an
Intent");
myPicture = getContentResolver().insert
(Media.EXTERNAL_CONTENT_URI, values);
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
i.putExtra(MediaStore.EXTRA_OUTPUT, myPicture);
startActivityForResult(i, 0);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if(requestCode==0 && resultCode==Activity.RESULT_OK)
{
Intent inn = new Intent(Intent.ACTION_VIEW);
Log.v(TAG, "myPicture is " + myPicture.toString());
inn.setData(myPicture);
startActivity(inn);
}
}
The Camera activity launches, I take a picture (which does get saved
to the SD card), I click on Done. Then I get this line in my LogCat:
myPicture is content://media/external/images/media/53
Then I get a forced close on my app with the following stack trace:
Uncaught handler: thread main exiting due to uncaught exception

I'm thinking that my local Uri object myPicture is missing something
because I'm not refreshing it after the picture is actually taken,
that it's still a shell of an object and not a full-fledged picture.
So how does one go about getting a good Uri to pass to Gallery? If I
don't pass the Uri to the Camera, it will return to me a small version
of the bitmap and not really what I want to view. If I query the
ContentResolver it will return a Cursor. Do I build a new Uri from the
Cursor? Or can I somehow tweak my Uri to get checkStartActivityResult
to find Gallery for me? Thanks for your help.
