FileCrypt is an opensource android application able to perform AES-128 bit encryption on all types of files.
Application Developer: Ravin Kumar
Steps to follow, for android target sdk 33-
1. After Installation, provide the File and Media permission, otherwise app will crash at startup.
2. Encrypted file will be stored inside Documents folder with name FileCrypt_filename.
3. Decrypted file will be stored inside Documents folder with original filename.

The working demonstration of FileCrypt is available at Youtube.
Note: This android application uses AES-128 bit for encryption which is considered good for general purpose use, please do consult a security expert regarding your required security standards.
Iteration: increasing the value will increase the security, select it based on the computation power of your device.
People often select it around 100,000.
Note: In case you set your own Iteration value please do remember it, as for decryption this parameter must be same as that of used during encryption.
Note: In the source code, the code of RealPathUtil.java is taken from link, which was made opensourced by Merab Tato Kutalia. This file is used to retrieve file path from uri.
