I have implementing custom Content Provider.
And I want to use Camera intent
Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(intent, requestCode);
but i don't know what uri to pass so i can add the result image to the content provider
onActivityResult returns null data when i dont put extra.
Any help ? Thanks in advance !
but i don't know what uri to pass so i can add the result image to the content provider
Pass a Uri
pointing to where you want the camera app to store the photo. Since nobody knows what your custom ContentProvider
is doing in openFile()
or related methods, we cannot give you more specific advice.
In the following activity, from this sample app , I am using FileProvider.getUriForFile()
to create a valid Uri
to where FileProvider
can save to the desired file:
