Problems running Unix commands in native Android Java...

Hello,
I've been trying to do some android stuff on java for some time now, and i've come across a problem here: i can't get the app to execute linux stuff, as there is no system() method like on other platforms... so i searched some code and found this:
Code:
protected void system(String[] Commands){
e Process process = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(process.getOutputStream());
DataInputStream osRes = new DataInputStream(process.getInputStream());
Vector<String> res = new Vector<String>();
for (String single : Commands) {
e os.writeBytes(single + "\n");
e os.flush();
e res.add(osRes.readLine());
// Log.e("CMDs", osRes.readLine());
}
e os.writeBytes("exit\n");
e os.flush();
process.waitFor();
}
However that won't work because of some errors i have in the marked lines:
"Unhandled exception type IOException"
and the process.waitFor(); line also gives me an error:
"Unhandled exception type InterruptedException"
Any ideas?

You need to add a try/catch block around that code which catches the IO exception and the interrupted exception.

So, first of all thanks to both of you it appears to be working now... i tried in on the emulator, and of course "su" didn't work there (broken pipe), so i replaced it by "sh", however this didn't seem to work well too. the application just locked up with a warning in android.... strange...
edit: tried using /system/bin/sh, didn't work, locked up again

What version of Android in the emulator? I've done it with 1.5 through 2.2 in the emulator, just by using "sh".

could you post the code you used please? would be AWESOME!
i'm trying to get this working on 2.1

Sure, I can post some more details later, but for now just the code.
Include the file in your project and use with:
Code:
ShellCommand cmd = new ShellCommand();
CommandResult r = cmd.sh.runWaitFor("ls -l");
if (!r.success()) {
Log.v(TAG, "Error " + r.stderr);
} else {
Log.v(TAG, "Success! " + r.stdout);
}
If you want su you can either use cmd.shOrSu().runWaitFor("..."); which will try su (by running "id", it just tests the status code but it's a nice entry in logcat for debugging) and fallback to sh. Or you can use cmd.su.runWaitFor("...");

Thanks kevin The code you are using there is awesome Looking good so far, however it keeps returning permission denied... is it some setting in the android manifest?

Actually "Permission denied" often also means "no such file or directory" on android :-/ . It's very frustrating.
Try running something simple to start with like:
cmd.sh.runWaitFor("echo foo");

yep, i tried running echo as i was confused by the "permission denied" although i had already set write permissions for the sdcard... didn't work, for some odd reason

[Q] Can I register a listener on process state?

I'm an experienced developer but new to Android development. I have an app that runs some native binaries, and I provide a status indicator to show when the native process is running and when it's not. Currently I poll the device to figure this out, using the ActivityManager API to determine if specific processes are running or not.
I'm hoping there is some way to register a listener on process state changes, so I can get notified when my process starts or stops. I looked through the API, and there doesn't seem to be such a thing. Does anyone know how I can keep track of process start and stop other than polling via ActivityManager?

Afaik there's no way to accomplish that other than your way or being system/root app. See this similar question here for reference.

Can you show how you start the process?

Sure. Here's the class that manages starting, stopping, and statusing (running or not) the binary executable. In this case, it's the omniNames service of the omni ORB (CORBA broker).
Code:
public class RHManager {
private TimerTask task = new TimerTask() {
@Override
public void run() {
if (RHManager.this.listener != null) {
listener.running(isOmniNamesRunning());
}
}
};
private IStatusListener listener;
public RHManager() {
}
public void startOmniNames() {
final Exec exec = new Exec();
final String[] args = new String[]
{RhMgrConstants.INSTALL_LOCATION_OMNI_NAMES_SCRIPTS + "/" + RhMgrConstants.OMNI_NAMES_SCRIPT_FILE,
"start"};
final String[] env = new String[] {"LD_LIBRARY_PATH=/sdcard/data/com.axiosengineering.rhmanager/omniORB/lib"};
Thread t = new Thread() {
public void run() {
try {
int res = exec.doExec(args, env);
logMsg("omniNames start return code " + res);
} catch (IOException e) {
logMsg("Failed to start omniNames");
e.printStackTrace();
}
String std = exec.getOutResult();
logMsg("omniNames start: std out==> " + std );
String err = exec.getErrResult();
logMsg("omniNames start: err out==> " + err );
};
};
t.start();
logMsg("omniNames started");
}
private boolean isOmniNamesRunning() {
String pid_s = getOmniNamesPid();
Integer pid = null;
if (pid_s != null) {
try {
pid = Integer.parseInt(pid_s);
} catch (NumberFormatException e) {
return false;
}
}
if (pid != null) {
RunningAppProcessInfo activityMgr = new ActivityManager.RunningAppProcessInfo("omniNames", pid, null);
return activityMgr.processName != null ;
}
return false;
}
public void stopOmniNames() {
String pid = getOmniNamesPid();
android.os.Process.killProcess(Integer.parseInt(pid));
android.os.Process.sendSignal(Integer.parseInt(pid), android.os.Process.SIGNAL_KILL);
}
private String getOmniNamesPid() {
Exec exec = new Exec();
final String[] args = new String[]
{RhMgrConstants.INSTALL_LOCATION_OMNI_NAMES_SCRIPTS + "/" + RhMgrConstants.OMNI_NAMES_SCRIPT_FILE,
"pid"};
String pid = "";
try {
int res = exec.doExec(args, null);
logMsg("oniNames pid return code: " + res);
} catch (IOException e) {
logMsg("Failed to start omniNames");
e.printStackTrace();
return pid;
}
String std = exec.getOutResult();
logMsg("omniNames pid: std out ==> " + std);
String err = exec.getErrResult();
logMsg("omniNames pid: err out ==> " + err);
String[] parts = std.split("\\s+");
if (parts.length >= 2) {
pid = parts[1];
}
return pid;
}
//monitor omniNames status and report status periodically to an IStatusListener
public void startMonitorProcess(IStatusListener listener, String string) {
this.listener = listener;
Timer t = new Timer();
t.schedule(task, 0, 1000);
}
private void logMsg(String msg) {
if (RhMgrConstants.DEBUG) {
System.err.println(msg);
}
}
}
Here's the Exec class that handles invocation of Runtime#exec(), consumes std and err out, and reports those and process return status to the caller.
Code:
public class Exec {
private String outResult;
private String errResult;
private Process process;
private boolean failed = false;
StreamReader outReader;
StreamReader errReader;
public int doExec(String[] cmd, String[] envp) throws IOException{
Timer t = null;
try {
process = Runtime.getRuntime().exec(cmd, envp);
outReader = new StreamReader(process.getInputStream());
outReader.setPriority(10);
errReader = new StreamReader(process.getErrorStream());
outReader.start();
errReader.start();
t = new Timer();
t.schedule(task, 10000);
int status = process.waitFor();
outReader.join();
errReader.join();
StringWriter outWriter = outReader.getResult();
outResult = outWriter.toString();
outWriter.close();
StringWriter errWriter = errReader.getResult();
errResult = errWriter.toString();
errWriter.close();
return (failed ? -1: status);
} catch (InterruptedException e) {
return -1;
} finally {
if (t != null) {
t.cancel();
}
}
}
public int doExec(String[] cmd) throws IOException{
return doExec(cmd, null);
}
public String getOutResult(){
return outResult;
}
public String getErrResult(){
return errResult;
}
private static class StreamReader extends Thread {
private InputStream is;
private StringWriter sw;
StreamReader(InputStream is) {
this.is = is;
sw = new StringWriter(30000);
}
public void run() {
try {
int c;
while ((c = is.read()) != -1){
sw.write(c);
}
}
catch (IOException e) { ; }
}
StringWriter getResult() {
try {
is.close();
} catch (IOException e) {
System.err.println("Unable to close input stream in StreamReader");
}
return sw;
}
}
private TimerTask task = new TimerTask() {
@Override
public void run() {
failed = true;
process.destroy();
}
};
}
Here's the script that startOminNames() invokes. It's the shell script installed with omniORB with functions other than start and get_pid removed, since those are handled by Android classes. You can invoke any executable in place of the script, or wrap your executable in a script.
Code:
#
# omniNames init file for starting up the OMNI Naming service
#
# chkconfig: - 20 80
# description: Starts and stops the OMNI Naming service
#
exec="/sdcard/data/com.axiosengineering.rhmanager/omniORB/bin/omniNames"
prog="omniNames"
logdir="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs"
logfile="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs/omninames-localhost.err.log"
options=" -start -always -logdir $logdir -errlog $logfile"
start() {
#[ -x $exec ] || exit 5
echo -n $"Starting $prog: "
$exec $options
}
get_pid() {
ps | grep omniNames
}
case "$1" in
start)
start && exit 0
$1
;;
pid)
get_pid
;;
*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
exit 2
esac
exit $?
And here's the IStatusListener interface
Code:
public interface IStatusListener {
public void running(boolean running);
}
Runtime.exec() has some pitfalls. See this helpful Runtime.exec tutorial for a nice explanation.

[Help] Android GUI for privoxy+polipo

Hi
How are you?
I have make simple android GUI to start privoxy and polipo binary
but my problem.How i can stop privoxy and polipo when press on stop button
i can get process id (PID) for privoxy and polipo using this code
Code:
public int findProcessIdWithPS(String str) throws IOException {
String readLine;
Runtime runtime = Runtime.getRuntime();
CharSequence name = new File(str).getName();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(runtime.exec("ps " + name).getInputStream()));
bufferedReader.readLine();
do {
readLine = bufferedReader.readLine();
if (readLine == null) {
return -1;
}
} while (!readLine.contains(name));
return Integer.parseInt(readLine.split("\\s+")[1]);
}
this code return the PID of process
then i have try kill process but not working with this code
Code:
Process process = Runtime.getRuntime().exec("kill -9 " + findProcessIdWithPS("privoxy"));
process.waitFor();
but this code not working with me
Please any help
Sorry of my English
