"no such algorithm: ECDSA for provider BC" when connect(host, port) from Android app

I was able to use the sshj lib to connect, authenticate, and execute remote commands from a standalone Kotlin client (command line).

But then when I tried to use the lib from a simple Android app it failed to even connect to the same server I used before from command line app.

I get `net.schmizz.sshj.transport.TransportException: no such algorithm: ECDSA for provider BC` (please see below the full error stack #1 from logcat):

The code is very simple:

```
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
CoroutineScope(Dispatchers.IO).launch{
val ssh = SSHClient()
ssh.addHostKeyVerifier(PromiscuousVerifier()) // it makes no difference
ssh.connect("www.blabla.com", 22223) <== it throws exception even before authenticating
//ssh.authPublickey(username, kp)
}
}
}
```

I've tried to add the following dependencies, but nothing really helped:

```
dependencies {
//...
implementation 'org.bouncycastle:bcpkix-jdk15on:1.70'
implementation 'com.hierynomus:sshj:0.34.0'
```

Any idea what I'm doing wrong?

Also I'm new to Android + Java + Kotlin dev, I see in "Project Structure..." I do have 6 x ways to add `sshj`:

What do they mean?
Are they all valid options?
Why in my error stack #1 I see `net.schmizz.sshj*`, even I'm actually using `com.hierynomus:ssh*`?!

[...]

BTW I've tried to replace com.hierynomus:ssh => net.schmizz.sshj, only to get another fatal exception:

`net.schmizz.sshj.transport.TransportException: Unable to reach a settlement: [diffie-hellman-group14-sha1, diffie-hellman-group1-sha1] and [curve25519-sha256, curve25519-sha256@libssh.org, ecdh-sha2-nistp256, ecdh-sha2-nistp384, ecdh-sha2-nistp521, sntrup761x25519-sha512@openssh.com, diffie-hellman-group-exchange-sha256, diffie-hellman-group16-sha512, diffie-hellman-group18-sha512, diffie-hellman-group14-sha256]`

(also see full error stack below)

Thanks for help,
