JSCH print System.err message on textview - android-studio

Question

I have solved this:
My solution:
I print ErrStream into 'in2' and then print it out just like 'in'
InputStream in2 = ((ChannelExec) channel).getErrStream();
My goal:
-To print Error message "bash: dumper: command not found" (as shown on android monitor) from System.err on textview
My Question:
-How can I read the Error message from System.err?
What is the code for:
-get ssh commands from user then display as what is it return
public void ssh_send_cmd(String input_cmd) {
ssh_input_cmd = input_cmd;
Runnable runnable = new Runnable() {
public void run() {
IDList.clear();
Connection connection = null;
Session session= null;
try {
JSch jsch = new JSch();
// Get SSH session
session = jsch.getSession(Global.servUser, Global.host, Global.port);
session.setPassword(Global.servPwd);
java.util.Properties config = new java.util.Properties();
// Never automatically add new host keys to the host file
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
// Connect to remote server
session.connect();
System.out.println("Connection through ssh established!");
String command = ssh_input_cmd;
Channel channel = session.openChannel("exec");
((ChannelExec) channel).setCommand(command);
((ChannelExec) channel).setErrStream(System.err);
InputStream in = channel.getInputStream();
System.out.println("Connect to session...");
channel.connect();
byte[] tmp = new byte[1024];
while (true) {
while (in.available() > 0) {
int i = in.read(tmp, 0, 1024);
if (i < 0) {
break;
}
System.out.print(new String(tmp, 0, i));
update_monitor(new String(tmp, 0, i));
}
if (channel.isClosed()) {
System.out.println("exit-status: " + channel.getExitStatus());
update_monitor("exit-status: " + channel.getExitStatus());
break;
}
try {
Thread.sleep(1000);
} catch (Exception ee) {
System.out.println(ee);
}
}
channel.disconnect();
}catch (Exception e) {
System.out.println(e);
update_monitor("error 1");
}finally{
if(session !=null && session.isConnected()){
session.disconnect();
}
}
}
};
Thread mythread = new Thread(runnable);
mythread.start();
}
Android Monitor:
com.example.acer.ssh_cmd I/System.out: Connection through ssh established!
com.example.acer.ssh_cmd I/System.out: Connect to session...
com.example.acer.ssh_cmd W/System.err: bash: dumper: command not found
com.example.asus.ssh_cmd I/System.out: exit-status: 127
bash: dumper:command not found
For your information: "dumper" is input from user and the command is not found
