I have a modified bluetooth chat program, that displays coming data from other device on screen. That works nicely, when using arduino and sending data. Now I would like to add a feature that when on screen pops message: "EMPTYING", then it would detect that and run a asynctask, but I cannot get it to work.
Here is the part that gets data and displays it on the screen.
`public void run() { byte[] buffer = new byte[1024]; int bytes;
String strRx = "";
int c = 0;
int k = 0;
//BLuetoothi pakettide vastuvõtmine ja ekraanile panek
while (true) {
try {
//Mingi data tuleb, seega ekraanile
if (connectedInputStream.available() > 0) {
bytes = connectedInputStream.read(buffer);
final String strReceived = new String(buffer);
runOnUiThread(new Runnable() {
@Override
public void run() {
// textStatus.append(strReceived);
textStatus.setText(strReceived);
String strReceivedCut=strReceived.substring(0,8); //Lõikab stringist esimese osa välja
boolean resultOfComparison=new String("EMPTYING").equals(strReceivedCut);
if(resultOfComparison==true) {
testkast.setText("It Happened");
//long timeNow= System.currentTimeMillis(); //Praegune hetk
//long startTime = System.currentTimeMillis();
//if(timeNow-startTime>1000*60*10) { //Should be 10 minutes
new UploadBySSH().execute(strReceived); //Saadame algse stringi SSH-ga servusse
//}
}
}
});
//Mingit datat ei tule, seega ootame Sleep
} else SystemClock.sleep(100);
//Keepalive osa, mis saadab ? mingi aja tagant
//hetkel on ajaks 10*100=1000 millisekundit
//Originaal programmi keepalive:
//;E??????????;E??????????;E??????????;E??????????;E??????????;E??????????
c++;
if (c > 10) {
String kl = "?";
byte[] bytesToSend = kl.getBytes();
connectedOutputStream.write(bytesToSend);
c = 0;
k++;
}
} catch (IOException e) {
e.printStackTrace();
final String msgConnectionLost = "Ühendus nurjus: PANE PROGRAMM KINNI\n"
+ e.getMessage();
runOnUiThread(new Runnable() {
@Override
public void run() {
textStatus.setText(msgConnectionLost);
}
});
}
}
}`
Here is the part that would ssh into a server.
private class UploadBySSH extends AsyncTask<String, Void, String> {
@Override
protected String doInBackground(String... args) {
try {
JSch ssh = new JSch();
Session session = ssh.getSession("root", "192.168.4.234", 22);
// Remember that this is just for testing and we need a quick access, you can add an identity and known_hosts file to prevent
// Man In the Middle attacks
java.util.Properties config = new java.util.Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.setPassword("password");
session.connect();
ChannelExec channel = (ChannelExec) session.openChannel("exec");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
channel.setOutputStream(baos);
channel.setCommand("/usr/bin/python /mnt/sda2/www/insert.py "+args[0]);
channel.connect();
channel.disconnect();
Boolean success = true;
session.disconnect();
} catch (JSchException e) {
System.out.println(e.getMessage().toString());
e.printStackTrace();
}
return "Executed";
}
}
Could anybody give some hints? Cannot that first part of code not find the ssh code? :S
