I'm trying to use BouncyCastle with android to implement ECDH and EL Gamal. I've added the bouncycastle jar file (bcprov-jdk16-144.jar) and written some code that works with my computers jvm however when I try and port it to my android application it throws:

java.security.NoSuchAlgorithmException: KeyPairGenerator ECDH implementation not found

A sample of the code is:

Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());

java.security.KeyPairGenerator keyGen = org.bouncycastle.jce.provider.asymmetric.ec.KeyPairGenerator.getInstance("ECDH", "BC");
                ECGenParameterSpec ecSpec = new ECGenParameterSpec("prime192v1");

                keyGen.initialize(ecSpec, SecureRandom.getInstance("SHA1PRNG"));



                KeyPair pair = keyGen.generateKeyPair();
                PublicKey pubk = pair.getPublic();
                PrivateKey prik = pair.getPrivate();

I then wrote a simple program to see what encryption algorithms are available and ran it on my android emulator and on my computers jvm the code was:

Set<Provider.Service> rar = new org.bouncycastle.jce.provider.BouncyCastleProvider().getServices();
    Iterator<Provider.Service> ir = rar.iterator();
    while(ir.hasNext())
        System.out.println(ir.next().getAlgorithm());

On android I do not get any of the EC algorithms while ran normally on my computer it's fine.

I'm also getting the following two errors when compiling for a lot of the bouncy castle classes:

01-07 17:17:42.548: INFO/dalvikvm(1054): DexOpt: not resolving ambiguous class 'Lorg/bouncycastle/asn1/ASN1Encodable;'

01-07 17:17:42.548: DEBUG/dalvikvm(1054): DexOpt: not verifying 'Lorg/bouncycastle/asn1/ess/OtherSigningCertificate;': multiple definitions

What am I doing wrong?
