Hi Guys,
Im trying to run an unix command from my application,
Basically I want to extract a tar file, but Im getting an I/O
exception while running the below code.
Can you please tell me as to how this has to be done
////////////////////////////
executeCommand("tar", "- xvf", pathOfFileToBeExtracted);
///////////////////////////
public static void executeCommand(String command, String arg0, String
arg1) throws Exception {
try {
Class execClass = Class.forName("android.os.Exec");
Method createSubprocess =
execClass.getMethod("createSubprocess",
String.class, String.class, String.class, int[].class);
Method waitFor = execClass.getMethod("waitFor",
int.class);
int[] id = new int[1];
FileDescriptor fileDescriptor = (FileDescriptor)
createSubprocess.invoke(
null, command, arg0, arg1, id);
FileInputStream inputStream = new
FileInputStream(fileDescriptor);
BufferedReader reader = new BufferedReader(new
InputStreamReader
(inputStream));
String output = "";
String line;
while ((line = reader.readLine()) != null) {
output += line + "\n";
}
waitFor.invoke(null, id[0]);
} catch (Exception e) {
System.out.println(e);
throw new Exception();
}
}
