How to delete pkcs7 padding from AES encrypted strings in Android?

I'm using my own custom encryption method to develop secure applications, and I'm having problems decrypting messages

This is my password

private static void myCryptography(){

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
byte[] input = "Hitesh Dhamshaniya".getBytes();
byte[] keyBytes = "ABCD657865BHNKKK".getBytes();
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC");

// encryption pass

cipher.init(Cipher.ENCRYPT_MODE, key);
byte[] cipherText = new byte[cipher.getOutputSize(input.length)];
int ctLength = cipher.update(input, 0, input.length, cipherText, 0);
ctLength += cipher.doFinal(cipherText, ctLength);
Log.e("==> ", " == > Encode " + Base64.encodeToString(cipherText, Base64.DEFAULT));
String encodedStr = Base64.encodeToString(cipherText, Base64.DEFAULT);
// decryption pass

cipherText = Base64.decode(encodedStr, Base64.DEFAULT);
cipher.init(Cipher.DECRYPT_MODE, key);
byte[] plainText = new byte[cipher.getOutputSize(ctLength)];
int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0);
ptLength += cipher.doFinal(plainText, ptLength);
Log.e("==> ", " == > Decoded " + new String(plainText, "UTF-8"));

}

Below output

How to delete unnecessary characters from decoded strings, such as ""

resolvent:

The password will automatically delete the padding. What you see here comes from the conversion from byte array plaintext to string. You should only use the first ptlength bytes instead of the whole array:

new String(plainText, 0, ptLength, "UTF-8")
