Any Good way of securing assets and video file store internal in android or react-native

Question

We are building completely offline commercial eLearning app. we have to store some important video locally in the app and we don't want that to be stolen by extracting apk.

Is there any good way to achieve this with encryption/decryption or password protection etc on native android or react-native.

We are trying various solutions but a better way from you will help us in saving time and learning.

Answer 1

You can't do it.

You can encrypt it, but application will need key to decrypt it. Key can be sniffed or extracted from bytecode. Or even screen can be recorded without any key extraction.

Don't spend time on making troubles for anyone, spend time on great content.
