Hi Megha,
Thanks for the sample app, but for the next release (1.0) would it be
possible to let the native Camera application respond to an
ACTION_GET_CONTENT intent and return with a media store content uri,
like the Pictures application does now. This way I can use:
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult( Intent.createChooser(intent,
getText(R.string.get_picture)) , 1);
To let the user choose if he/she wants to get a picture from the
Camera app or the Pictures app. Currently only the Pictures app works
this way.
I can then simply use the code below to get the resulting picture with
any location information (if available).
protected void onActivityResult(int requestCode, int resultCode,
Intent data) {
if (resultCode == RESULT_OK)
{
if (requestCode == 1)
{
Uri uri = data.getData();
ContentResolver cr = context.getContentResolver();
Bitmap bitmap =
BitmapFactory.decodeStream( cr.openInputStream(uri) );
double latitude = 0;
double longitude = 0;
Cursor c = cr.query(uri, new String[] {
MediaStore.Images.ImageColumns.LATITUDE,
MediaStore.Images.ImageColumns.LONGITUDE
}, null, null, null);
if (c != null) {
c.moveToFirst();
latitude =
c.getDouble(c.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.LATITUDE));
longitude =
c.getDouble(c.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.LONGITUDE));
}
// Alternatively if the Camera does not use a media store
content uri it could return the latitude and longitude in the extra
fields of the intent.
}
}
}
Using the code above, I don't even have to worry about how the Camera
works but I will give the user the option of using the Camera or any
other app that supports GET_CONTENT with image/*.
So I hope you can add support for the GET_CONTENT action in the Camera
app. It should not be that hard because
MediaStore.ACTION_IMAGE_CAPTURE uses a similar approach but does not
return an uri. And the camera app already stores pictures in the media
store on the sdcard.
I think this would also solve a lot of problems people are having in
the developer forum about getting a picture from the camera.
Thanks
