Android 在具有无效参数的根电话上执行进程

假设：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(SU);
DataOutputStream processStream = new DataOutputStream(process.getOutputStream());
processStream.writeChars("cat /qwerty");
processStream.writeChars(EXIT);
processStream.flush();

int status = process.waitFor();

Log.d("EXIT STATUS", String.valueOf(status));

process.waitFor（）导致当前线程永远等待。我想问题在于无效的命令（我故意这么做）。但我如何处理这种情况呢

Busybox 1.17.1
当您使用writeChars发送命令时，它们在shell中都处于同一行，我认为从未实际执行过。您需要添加新行以使shell执行。试试这个：

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(SU);
DataOutputStream processStream = new DataOutputStream(process.getOutputStream());
processStream.writeChars("cat /qwerty\n");
processStream.writeChars("exit \n");
processStream.flush();

int status = process.waitFor();

Log.d("EXIT STATUS", String.valueOf(status));
