I am trying to connect to a server using this code, I tried the code in NetBeans as regular java frame and it works, when I transferred to android the application keep crashing. I added to manifest is there something else I have to add or something wrong with the code?
public class MainActivity extends AppCompatActivity {
String host;
String ip;
String password;
Session s;
int x;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onClick(View view) throws Exception {
EditText t1 = (EditText) findViewById(R.id.editText);
EditText t2 = (EditText) findViewById(R.id.editText2);
EditText t3 = (EditText) findViewById(R.id.editText3);
if (t1 != null && t2 != null && t3 != null) {
host = t1.getText().toString();
ip = t2.getText().toString();
password = t3.getText().toString();
JSch jsch = new JSch();
Session session = jsch.getSession(host, ip, 22);
session.setPassword(password);
// Avoid asking for key confirmation
Properties prop = new Properties();
prop.put("StrictHostKeyChecking", "no");
session.setConfig(prop);
session.connect();
// SSH Channel
ChannelExec channelssh = (ChannelExec)
session.openChannel("exec");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
channelssh.setOutputStream(baos);
// Execute command
channelssh.setCommand("ls");
channelssh.connect();
channelssh.disconnect();
}
else {
Toast.makeText(MainActivity.this, "Invaild Input", Toast.LENGTH_LONG).show();
}
}
}
