RSA encryption Android to C#, Bad Data Exception

RSA encryption Android to C#, Bad Data Exception

I want to encrypt some text from android and send to C# server, server
suppose to decrypt it but it keep throwing BadDataException. I've been
searching for solution for hours. Found none so far.
Here is android code
static final String pubKeyMod =
"weiz/bxDRnL2IotCt9zt51MhKa/k5nsOR4KSw5DUbtkv727vsvzdKGKXCmkGsJ9qbT30UIB80v57H0354+w1HxIO0nWTVzLWBveoYRQHL/UdkSLJPHFkp5KQWmUYvJtd8BjRG/agFCN4vbgNkqavYr/5HjhaxM8DpzZQ+KMQvTU=";
static final String pubKeyExpo = "AQAB";
static final BigInteger modulus = new BigInteger(1,
Base64.decode(pubKeyMod, Base64.DEFAULT));
static final BigInteger exponent = new BigInteger(1,
Base64.decode(pubKeyExpo, Base64.DEFAULT));
public static String Encrypt(String text) {
try {
PublicKey pubKey =
KeyFactory.getInstance("RSA").generatePublic(new
RSAPublicKeySpec(modulus, exponent));
Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.ENCRYPT_MODE, pubKey);
byte[] textBytes = text.getBytes("UTF8");
byte[] encryptedBytes = cipher.doFinal(textBytes);
return Base64.encodeToString(encryptedBytes, Base64.DEFAULT);
}
catch (Exception e) {
e.printStackTrace();
}
return null;
}
here is C# decoder
public static string Decrypt(string stringData)
{
try
{
byte[] data =
Decrypt(System.Convert.FromBase64String(stringData));
return Encoding.UTF8.GetString(data);
}
catch (Exception ex)
{
ShowError(ex);
}
return null;
}
static byte[] Decrypt(byte[] encData)
{
string privateKey =

var rsaCSP = new RSACryptoServiceProvider();

tbytes.Length);
decData.AddRange(rsaCSP.Decrypt(tbytes, false));
totalWrote += chunkSize;

return decData.ToArray();
}
PS : Keys are left for testing purpose. Thanks.
