Question

每当我的应用尝试发送意图邮寄任何邮件应用时，它都会崩溃。有人可以帮我解决这个问题吗？

这是我的意图的xml代码：

Intent intent =  new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:"));
    intent.setType("*/*");
    intent.putExtra(Intent.EXTRA_EMAIL, "jainharshil670@yahoo.in");
    intent.putExtra(Intent.EXTRA_SUBJECT, "My Coffee Order");
    intent.putExtra(Intent.EXTRA_TEXT, priceMessage);
    startActivity(intent);

应用程序在日志文件中提供的错误消息是：

Answer 1

以这种方式向您的清单添加活动：

  <activity   android:name=".AppPreferenceActivity" android:label="@string/app_name">  
     <intent-filter> 
       <action android:name="com.scytec.datamobile.vd.gui.android.AppPreferenceActivity" />  
         <category android:name="android.intent.category.DEFAULT" />  
     </intent-filter>   
  </activity>

Answer 2

line 2:++++execSync('powershell get-netipaddress '+ip)消除了您在setType()中的价值。相反，结合：

setData()

成：

intent.setData(Uri.parse("mailto:"));
intent.setType("*/*");
intent.putExtra(Intent.EXTRA_EMAIL, "jainharshil670@yahoo.in");

（将intent.setDataAndType(Uri.parse("mailto:jainharshil670@yahoo.in"), "text/plain");替换为text/plain中所含内容的实际MIME类型

Answer 3

这意味着android系统没有找到任何电子邮件发送活动来处理您创建的意图。确保您的设备中安装了电子邮件应用程序。

还可以使用以下代码发送电子邮件，

<% if @posts.present? %>
  <% @posts.each do |post| %>
    <%= link_to "#{post.title}", post_path(post) %>
  <% end %>
<% else %>
    <p> You don't have any post yet. Keep posting! </p>
<% end %>

Answer 4

我在发布这个问题之后就知道了。

当我看到行

时，我发现了它

intent.setData(Uri.parse("mailto:"));
intent.setType("*/*");

然后我删除了： -

intent.setType("*/*");

然后一切都很好。

应用程序在向邮件应用程序发送意图时崩溃
