I am trying encryption and decryption using cipther,AES algorithm but while decrypting its throwing error bad decrypted file?

@SuppressWarnings("resource")
public static void encrypt(SecretKey key, /*AlgorithmParameterSpec paramSpec,*/ AlgorithmParameterSpec paramSpec, InputStream in, OutputStream out)
throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException,
InvalidAlgorithmParameterException, IOException
try
byte iv = new byte (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A, (byte) 0x8E, 0x12, 0x39, (byte) 0x9C,
0x07, 0x72, 0x6F, 0x5A ;
//generate new AlgorithmParameterSpec
// AlgorithmParameterSpec paramSpec = new IvParameterSpec(iv);
Cipher c = Cipher.getInstance(ALGO_VIDEO_ENCRYPTOR);
c.init(Cipher.ENCRYPT_MODE, key, paramSpec);
out = new CipherOutputStream(out, c);
Log.d("tag","out"+out);
int count = 0;
byte buffer = new byte[DEFAULT_READ_WRITE_BLOCK_BUFFER_SIZE];
while ((count = in.read(buffer)) >= 0)
out.write(buffer, 0, count);

finally
out.close();
