Build a DP maker functionality apk.
-Use a firebase database.
1. Implement the designs.
2. The DP samples is to be uploaded in firebase manually and it would be called in the app using API. So you will be writing this API. The white space that you see is where the user photo would be uploaded.
3. The App flow is very simple
a. 800x800-bjp03 this is an example of the design that would be uploaded in the database
b. Sample-dp-fullscreen02 is the first screen. User will click on the create DP.
c. creation page is where user will upload his photo or click fresh photo.
d. Photoedit-screen is where user will adjust the position of user photo so put the frame.
e. Designformat-screen is where the user saves it and the photo gets downloaded on his mobile. The DP is then saved into firebase database.
4. Remember that the frames are dynamic and would be uploaded in the firebase so you will have to put these frames on the clicked photo by the user. We have shared few samples for the same.
You need to write the technical document so that it would be understood by even a non-programmer. Imagine that you are giving it to a 10 year old kid and still he should be able to use it and work on it without any other communication.
