android 修改系统时间

使用adb查看 设置系统时间的格式

    public static void setSystemTime(String time) {
        try {
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.getDefault());
            Date date = format.parse(time);
            Process process = Runtime.getRuntime().exec("su");
            DataOutputStream os = new DataOutputStream(process.getOutputStream());
            String formatDate;
            if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
                format = new SimpleDateFormat("MMddHHmmyyyy.ss");
                formatDate = format.format(date);
                os.writeBytes("date " + formatDate + " set \n");
                os.writeBytes("busybox hwclock -w\n");
            } else {
                format = new SimpleDateFormat("yyyyMMdd.HHmmss");
                formatDate = format.format(date);
                os.writeBytes("/system/bin/date -s " + formatDate + "\n");
                os.writeBytes("clock -w\n");
            }
            os.writeBytes("exit\n");
            os.flush();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
