I try to run iperf server and client in my android device so i develop an app using exec() and it is working fine for ls, ping etc. command but when i try to run iperf -s i got error, Here is the code and i added internet permission in manifest file. Help will appreciate
What will be the working directory and environment for iperf command??
StringBuffer output = new StringBuffer();
Process p;
try {
p = Runtime.getRuntime().exec(command);
p.waitFor();
BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream()));
String line = "";
while ((line = reader.readLine())!= null) {
output.append(line + "\n");
}
}
I got following Error

Sound a permissions problem check your logcat line:
Maybe you can try execute a binary iperf in a external sd card? try to add permissions to read/write external storage.
