tc.run();
This is your problem. Here you call the run() method on the same thread.
In order to actually start a new thread, call
tc.start();
Question
Hi !!
I try to build an Android Application to control the Ar drone. But i have a problem when i try to connect my device with the drone. I created a Thread to do a socket. But when i run it in the main activity i have a exception : android.os.NetworkOnMainThreadException .
This is my code with my Thread in ThreadCmd class:
String commande="";
byte[] cmdToByte;
String iPinString;
InetAddress IpDrone;
DatagramSocket clientSocket;
Thread threadDecollage;
TextView tv ;
boolean etat;
DatagramPacket sendPacketWithCmd;
private byte[] ip = {(byte)192, (byte)168, (byte)1, (byte)1 };
boolean isRunning = true;
private final static long TIME_SLEEP= 20;
public void run() {
try {
IpDrone = InetAddress.getByAddress(ip);
} catch (UnknownHostException e1) {
e1.printStackTrace();
etat = false;
}
try {
clientSocket = new DatagramSocket();
} catch (SocketException e) {
e.printStackTrace();
etat = false;
}
while(isRunning){
runControl();
try {
Thread.sleep(TIME_SLEEP);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
public void runControl(){
commande ="AT*REF=1,290717696<LF>AT*REF=2,290717952<LF>AT*REF=3,290717696<LF>";
cmdToByte = commande.getBytes();
try {
sendPacketWithCmd = new DatagramPacket(cmdToByte,cmdToByte.length,IpDrone,5556);
clientSocket.send(sendPacketWithCmd);
} catch (IOException e) {
e.printStackTrace();
etat = false;
}
etat = true;
isRunning=false;
}
public boolean retourneetat(){
return etat;
}
After in the main activity :
Threadcmd tc = new Threadcmd();
tc.run();
I dont see my error so i ask to you if you can help me !! ( i don't forget the permission)
ps: please excuse my english :)
