经过数天的研究和努力，我发现了解决方案，可能有助于节省别人的时间。这是我的答案。我改变了上面的代码逻辑，像这样

现在发生了什么，我能够成功地加密文件并将其保存在SD卡中，然后解密它播放。其他人不能播放音频

public class Main2Activity extends AppCompatActivity {
    

    private String encryptedFileName = "encrypted_Audio.mp3"; 
    private static String algorithm = "AES"; 
    static SecretKey yourKey = null; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) {
    
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main2); 

     //saveFile("Hello From CoderzHeaven asaksjalksjals"); 
     try {
    
      saveFile(getAudioFile()); 
     } catch (FileNotFoundException e) {
    
      e.printStackTrace(); 
     } 
     decodeFile(); 

    } 

    public static SecretKey generateKey(char[] passphraseOrPin, byte[] salt) throws NoSuchAlgorithmException, InvalidKeySpecException {
    
     // Number of PBKDF2 hardening rounds to use. Larger values increase 
     // computation time. You should select a value that causes computation 
     // to take >100ms. 
     final int iterations = 1000; 

     // Generate a 256-bit key 
     final int outputKeyLength = 256; 

     SecretKeyFactory secretKeyFactory = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1"); 
     KeySpec keySpec = new PBEKeySpec(passphraseOrPin, salt, iterations, outputKeyLength); 
     SecretKey secretKey = secretKeyFactory.generateSecret(keySpec); 
     return secretKey; 
    } 

    public static SecretKey generateKey() throws NoSuchAlgorithmException {
    
     // Generate a 256-bit key
