I am developing a Ping application for Android 2.2.
I try my code and it works, but only in local IPs, that's my problem I want to do ping to external servers too.
Here is my code:
private OnClickListener milistener = new OnClickListener() {
public void onClick(View v) {
TextView info = (TextView) findViewById(R.id.info);
EditText edit = (EditText) findViewById(R.id.edit);
Editable host = edit.getText();
InetAddress in;
in = null;
// Definimos la ip de la cual haremos el ping
try {
in = InetAddress.getByName(host.toString());
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Definimos un tiempo en el cual ha de responder
try {
if (in.isReachable(5000)) {
info.setText("Responde OK");
} else {
info.setText("No responde: Time out");
}
} catch (IOException e) {
// TODO Auto-generated catch block
info.setText(e.toString());
}
}
};
Ping 127.0.0.1 -> OK
Ping 8.8.8.8 (Google DNS) -> Time Out
I put the following line at Manifest XML too:
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
Can anyone suggest me where I'm doing wrong?
I tried following code, which works for me.
private boolean executeCommand(){
System.out.println("executeCommand");
Runtime runtime = Runtime.getRuntime();
try
{
Process mIpAddrProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
int mExitValue = mIpAddrProcess.waitFor();
System.out.println(" mExitValue "+mExitValue);
if(mExitValue==0){
return true;
}else{
return false;
}
}
catch (InterruptedException ignore)
{
ignore.printStackTrace();
System.out.println(" Exception:"+ignore);
}
catch (IOException e)
{
e.printStackTrace();
System.out.println(" Exception:"+e);
}
return false;
}
