Question

我目前正在创建一个运行某些终端命令的Android应用程序。我正在使用genymotion Nexus 5（4.4.4）模拟器，它默认带有root。但是，为了测试一些常规命令，我执行了以下操作：

{{#section 'classes'}}has-navigation page-dashboard{{/section}}
{{#section 'body-classes'}}-fluid{{/section}}
 <div class="row" id="invoicer">
  <div class="col-xs-12 col-md-6">
   Fill your details and get live preview in the right side
     <form class="" action="/invoices" method="post" enctype="multipart/form-data">
  <div class="">
    <div class="invoiceform-logo-container">
      <input type="file" name="profilelogo" id="fileinput" accept="image/*" v-on:change="updateImage()">
      <img v-bind:src="logo" alt="" />
    </div>
    <div class="invoiceform-number"></div>
    <div class="invoiceform-currency"></div>
  </div>

  <div class="divider"></div>
  <div class="">
    Your Name / Company Name
    <textarea name="company_name" rows="8" cols="40" v-model="from"></textarea>
    Client Name / Company Name
    <textarea name="client_name" rows="8" cols="40" v-model="to"></textarea>

    \{{date_title}}
    <input type="date" name="start_date" v-model="date">

    \{{due_date_title}}
    <input type="date" name="end_date" v-model="due_date" v-bind:min="date">

      \{{unit_cost_header}}

      <input type="number" name="items[1][item_amount]" v-model="item.amount">

    <button type="button" name="button">Add Item</button>
  </div>

  <div class="divider"></div>
  <div class="">
    \{{subtotal_title}} \{{subtotal}}
    \{{tax_title}}

    <div class="input-group">
      <input type="text" class="form-control" aria-label="Text input with dropdown button" v-model="tax">
      <span class="input-group-addon">

      <span class="input-group-addon">
        <input type="radio" name="" aria-label="Checkbox for following text input"> F
      </span>
    </div>

    <div id="discount" v-if="fields.discount">

   </div>
 {{#section 'script'}}
  window.invoice = {{{json defaultInvoice}}}
  console.log({{{json defaultInvoice}}})
 {{/section}}

当＆＃34; su＆＃34;我从一个名为SuperUser的应用程序中获取一条消息，说我已获得root权限。但是没有其他命令被执行。没有tmp1 direcotry，我无法将我手动添加到模拟器的new4.txt文件拉到我的文档文件夹。

我在路径字符串中遗漏了什么？

Answer 1

当“su”执行时，我从名为SuperUser的应用程序中收到消息说我已获得root权限

所以我猜你正在手机上运行代码。在这种情况下，您还在手机上运行第三个命令（adb pull），而不是要在主机上运行。

作为this answer points out，您在不同的子shell中运行连续命令。因此，您的第一个su在第二个exec的上下文中无关紧要。要使用su执行命令，请参阅manual page of su。一个简单的例子是：

su - -c "whoami"

如何在rooted模拟器上创建的Android应用程序中运行终端命令？
