Android app on tablet to take pictures of items in warehouse

We need an android app to take pictures of items stored in our warehouse.

the working process should be as following:
1. type in 6 digit SKU of the item
2. take up to 12 pictures of the item.
3. see all the pictures of the current SKU and also be able to delete a picture
4. press next, SKU goes up by 1 to the next item number.
5. take picutes again ...
.
.
.

at the end of the day, the app should save a txt file with all the SKUs and filenames of the pictures that belong to the SKU
for example:
301727; pic139242.jpg; pic139243.jpg; pic139244.jpg;
301728; pic139245.jpg; pic139246.jpg;
301729; pic139248.jpg;
301730; pic139249.jpg;


we use google drive to automatically upload all the pictures and TXT file.
