透过Runtime.getRuntime().exec() 调用系统应用时，应该异步打印verbose信息

通过Runtime.getRuntime().exec() 调用系统应用时，应该异步打印verbose信息
如果你这样打， 可能会导致执行阻塞

private static void printInput(Process p) throws IOException {BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));String line;while ((line = in.readLine()) != null) {System.out.println(line);}in.close();}

        if (p.getErrorStream() != null) {            StreamPrinter errorStreamPrinter = new StreamPrinter(p.getErrorStream(), "", System.out);            errorStreamPrinter.start();  //StreamPrinter是一个线程        }        if (p.getInputStream() != null) {            StreamPrinter infoStreamPrinter = new StreamPrinter(p.getInputStream(), "[INFO]", System.out);            infoStreamPrinter.start();  //StreamPrinter是一个线程        }
