Java native process timeout

If you're using Java 8 or later (API 26 or later for Android) you could simply use the waitFor with timeout:

Process p = ...
if(!p.waitFor(1, TimeUnit.MINUTE)) {
    //timeout - kill the process. 
    p.destroy(); // consider using destroyForcibly instead
}

All other responses are correct but it can be made more robust and efficient using FutureTask.

For example,

private static final ExecutorService THREAD_POOL 
    = Executors.newCachedThreadPool();

private static <T> T timedCall(Callable<T> c, long timeout, TimeUnit timeUnit)
    throws InterruptedException, ExecutionException, TimeoutException
{
    FutureTask<T> task = new FutureTask<T>(c);
    THREAD_POOL.execute(task);
    return task.get(timeout, timeUnit);
}

final java.lang.Process[] process = new Process[1];
try {
    int returnCode = timedCall(new Callable<Integer>() {
        public Integer call() throws Exception {
            process[0] = Runtime.getRuntime().exec(command); 
            return process[0].waitFor();
        }
    }, timeout, TimeUnit.SECONDS);
} catch (TimeoutException e) {
    process[0].destroy();
    // Handle timeout here
}

If you do this repeatedly, the thread pool is more efficient because it caches the threads.
